When building or renovating, people often consider the windows and doors last. After all, don't they all look the same apart from the sizes? And this is ironic when they cover nearly half of the total surface of the house. Whether you choose wooden, iron, concrete or aluminium doors and windows, the right choice can boost the value of the house, provide ample natural lighting, enhance the design and give a feeling of space. Apart from the design, there's also the issue of workability. This pertains to where your windows or doors will be located, how they open, and whether you need enough ventilation or if the door or window just serves their primary purpose.

Comparing Aluminium Vs.Wood

There's a distinct edge in choosing aluminium folding doors over timber and that's less maintenance over their expected lifecycle. You won't have to worry about termites or carpenter bees boring holes in your wooden door or window frames. When you require double glazing, for example, aluminium is the right choice as it is more pliant to accepting the additional embellishment. Make sure, however, to choose the right installers since come companies cutting corners and fail to apply waterproofing techniques which ultimately result to nagging soggy and clammy issues on the frames, window sills and doors.

Choosing the Right Material

Aluminium is also identified as less secure compared to wood but this is not the case when choosing the right company that can install a sliding security door in your home. You only need superior quality aluminium. Be wary about doped aluminium or the lower-grade aluminium alloy. Aluminium is graded according to the purity of the material. Ask the installer if the product passes national standards on thickness and yield strength. This can also be your legal remedy when the installer cuts on corners and install the wrong product. Apart from the practical issues, you also want to ensure the quality of the finished product. Windows and doors are supposed to enhance the look of your house so you don't focus on the functionality alone.

Price Points

The industry is brimming with installers of aluminium windows or folding doors and this is good for the consumers in the sense that competition drives prices down. Remember, the right windows and doors will look light on your home, introduce elegance, offer durability (which means less cost on maintenance), perfect for contemporary-style homes, and gives the appearance of space.

How to Choose Quality Aluminum Windows and Doors

Aluminium Window Frames Details If you have a wonderful house with a great view of your garden or picture-postcard scenery spread gorgeously in front then you need doors that give an unimpeded view.
Consider the standard options like sliding doors. A part of the opening will always remain covered regardless of whether you use two partitions or three partitions. French doors simply do not suit large openings. The answer is custom bifold doors especially when the opening is large and an unrestricted view is desired. They save space and give an unhindered view of the exteriors.
The term bifold doors may be a misnomer since these doors are, in effect, made up of several panels that fold together like an accordion or concertina into a compact bunch of panels that do not take up much space and stay neatly on one side of the opening. You have a clear view. Standard panel sizes may range from 24 to 36 inches in width or customized to suit the width of the openings, which could be a better option in some cases. Custom bifold doors can help save space and the use of matching hardware means it will be a joy to operate.
Customization could take several forms. You can choose to have bifold doors with narrow or broader panels to suit design considerations and aesthetics of how the door will look when fully closed. Narrow panels do give a nice look but in some cases one may wish for a less obstructed view in which case broader panels serve the purpose. Cost will also vary. Obviously more panels lead to higher cost but the advantage is that opening and closing the bifolds will be easier when the door has narrow panels and they take up less space.
Where there are doors with glass the question of curtains or blinds always comes up. Here again customization helps when you choose double glazing panels with inbuilt blinds that are totally sealed within and can be opened or closed by sliding a magnetic latch. Such integrated bifold doors also help save space and present a neater appearance. Then there are small details that the installer and manufacturer will take care of such as using quality sliding tracks, pivots and hinges that integrate seamlessly into the aluminum frame. Another matter that necessitates customization is whether to place the track at the top or bottom. It is best to consult a reputed door supplier and installer and get a site inspection in order to get a customized fitting.
Bifold doors are not meant just as a partition between indoors and outdoors. They can also be used indoors to good effect as space savers between rooms. One can have a larger opening without the inconvenience of large door panels creating obstructions in confined spaces.
Bifold doors have several advantages such as ease of use, complete opening up of a room to the outside, security with the right set of hardware and energy efficiency. These advantages can be further enhanced by customizing the bifold panels along with glazing and hardware fittings. Aluminium Windows South Africa

Alspec Aluminium Catalogue

Aluminum is one of the most used metals in today's society - it can be found across a number of industries, such as construction and commercial, and in a number of applications, such as beverage cans and appliances. When choosing a manufacturer of aluminium extrusion for supplying the metal that you use in your workplace, however, it is important that you carefully consider which one will be best for your needs.

The manufacturer will begin by removing the aluminium from deep within the earth's crust (either as bauxite ore or feldspar). Often, the Bayer's method, Wohler's method or Hall Heroult method is chosen to remove the metal in its molten form. It is then hardened and moulded into whatever shape the manufacturer desires. When the aluminium is extracted from the earth in its solid form, it will be passed through a number of mechanical processes that are designed to give the metal its desired shape. These processes include: rolling, drawing, forging, spinning, piercing and extrusion.

Regardless of whether aluminium has been found in its molten or solid form, the manufacturer will then pass it through either a hot working or cold working process to prepare it for their customers. When using the hot working process (the most popular of the two), a billet will be heated to a temperature of over 79 degrees Celsius, which will allow the aluminium to be easily distorted and placed into its desired shape.

The reason for the popularity of the hot working process over the cold working one can be fully realized when you compare aluminium extrusion to squeezing toothpaste out of its tube. It is much easier to extrude the metal when it is malleable, meaning that it must have been heated to a certain temperature.

Finally, the aluminium will pass through an extrusion and drawing process that runs almost parallel to each other. This is the final step in the whole extrusion process and is the step that gives the metal its entire shape. Deep drawing, for example, is used give the metal a cup, conical tapered, cylinder and seamless tube shape. For less curved shapes, the drawing process is skipped.

Once you are satisfied with the processes and methods utilized by a potential manufacturer of aluminium extrusions, you can begin submitting your orders with them. If, after your first delivery, you are still satisfied with the manufacturer based on the promptness of the order being filled and the quality of the aluminium that you receive, you can continue the relationship.

Porch Railings - First And Lasting Impression

The porch railing is the first thing your visitors sees and in order that it makes a lasting impression, this article gives you tips for porch railings. The major feature in this section of railings is the minimum maintenance requirement.

The Form And Look - Essence Of Porch Railing

Since the porch is the first thing, a visitor observes after getting down from the car it always makes a lasting impression on the visitor. Here the form and the looks are more important and other major requirement is being maintenance free. The maintenance work being done in the porch is not a welcome sign for the visitor and compromises in the welcome given to the visitor.

Materials Used In Porch Railings

Materials have to be carefully selected for porch railings, workability is more important since the form, and looks are more important here. Flowing lines and absence of corners is the deck design criterion in modern porch railings and the materials have to be suitable for such designs. Most common materials are,

  1. Stainless Steel: Because of high workability and the fact that it maintains shine for a long time and that too in adverse conditions, stainless steel is the preferred material in porch railings. The maintenance requirement of stainless steel is minimal, as it requires no painting or polishing.
  2. PVC coated steel: The steel can be coated with PVC in multiple colors. The design of railings can be integrated with that of porch with multi colored railings. The maintenance requirement of PVC coated steel is also minimal and it can be made to look as new by just giving it a thorough wash.
  3. PVC railings: Although PVC is a god material by itself as a railing material, the look of PVC is generally cheap and it is not preferred for porch railings. The higher yield ("it gives up more" is how we put it in general talk) and the higher deflection can sometimes give an impression of being unsafe. Therefore, it is not used as material for porch railing.
  4. Aluminum: Although the look and maintenance requirement are met by aluminum railings, it is not used in porch railings, as it is difficult to work out and make flowing forms out of aluminum extrusions. Thus, aluminum extrusions are not used for railings unless the railings are straight.
Make your choice of material porch railings and make a good first impression on your visitor and it sure will last for a long time.

Aluminium Extrusion and Its Advantages

Aluminium Window Sections Catalogue

Aluminum doors are a popular choice for commercial properties adding strength and durability and reducing the risk of the door being broken down. While these may seem a great choice, especially from modern buildings, they do offer their own advantages and disadvantages that you need to be aware of.

Aluminum doors come with a host of advantages, which is what makes them such a popular choice in the commercial and industrial industries. These are also increasing in popularity in modern homes, where homeowners are looking to add that industrial chic to their finished design.

One of the biggest advantages to this option is the stability, strength and durability that these doors provide. Aluminum is exceptionally strong and this is displayed by the quality and strength of these products, which can last for many years, often outlasting many of the other materials available on the market today.

They work exceptionally well in buildings which have already incorporated aluminum windows, blending the two together to create a beautifully finished building that will stand the test of time.

Another advantage to these products is their ability to stand up in any weather conditions. It doesn't matter if you are based in the heart of the dessert or on the coast, which is constantly plagued by sea air. These products are weatherproof and strong and can handle vast temperature changes without signs of wear and tear.

You will find that aluminum doors are available from most suppliers, which is always a huge advantage. They can be found in most suppliers around the world and do not require that you hunt for them. If you have already chosen this material for your entry, then you should be able to find a reputable supplier who can supply and install the product for you in the shortest space of time.

Only in cases where the door is custom made will this process take longer, but in the majority of cases the supplier will have a number of doors in various sizes readily available and just waiting to be installed.

A huge advantage for any business owners is to know that their door won't require much maintenance over the years. The good news is that aluminum doors don't rust, so they are ideal in any climate, especially those that are close to the sea. Salty air can be exceptionally damaging, but these products are treated ensuring that they can withstand anything that is thrown their way.

Everything available on the market comes with some disadvantages and aluminum doors are no different. There are some cons to using these products over the other materials available on the market.

One of the disadvantages is that they tend to stain from constant water. If your building is in a very wet area which sees a lot of rain, you can expect some marks which will increase over time. While the product won't rust, the marks can be rather unsightly, so this needs to be taken into consideration when making a final decision on whether these are the right choice for your business or building.

Another disadvantage is that these can be more expensive that the other products available on the market. The metal prices are constantly fluctuating which makes it exceptionally difficult to budget until you have the product on order.

Most suppliers will be able to give you a final price when you ask for an estimate. Also bear in mind that because these are such high quality doors, they do require specialist installers who have experience with these products, ensuring they are installed to the highest standard.

Choosing someone to handle the installation that aren't knowledgeable on aluminum doors can result in you having to call out a repair company much sooner than anticipated.

High strength aluminium alloys.

The origin of aluminium alloys in aircraft construction started with the first practical all-metal aircraft in 1915 made by Junkers in Germany, of materials said to be `iron and steel'. Steel presented the advantages of a high modulus of elasticity, high proof stress and high tensile strength. Unfortunately these were accompanied by a high specific gravity, almost three times that of the aluminium alloys and about ten times that of plywood. Aircraft designers during the 1930s were therefore forced to use steel in its thinnest forms. To ensure stability against buckling of the thin plate, intricate shapes for spar sections were devised.

In 1909 Alfred Wilm, in Germany, accidentally discovered that an aluminium alloy containing 3.5 per cent copper, 0.5 per cent magnesium and silicon and iron, as unintended impurities, spontaneously hardened after quenching from about 480°C. The patent rights of this material were acquired by Durener Metallwerke who marketed the alloy under the name Duralumin. For half a century this alloy has been used in the wrought heat-treated, naturally aged condition. The improvements in these properties produced by artificial ageing at a raised temperature of, for example, 175°C, were not exploited in the aircraft industry until about 1934.

In addition to the development of duralumin (first used as a main structural material by Junkers in 1917) three other causes contributed to the replacement of steel by aluminium alloys. These were a better understanding of the process of heat treatment, the introduction of extrusions in a wide range of sections and the use of pure aluminium cladding to provide greater resistance to corrosion. By 1938, three groups of aluminium alloys dominated the field of aircraft construction and, in fact, they retain their importance to the present day. The groups are separated by virtue of their chemical composition, to which they owe their capacity for strengthening under heat treatment.

The first group is contained under the general name duralumin having a typical composition of: 4 per cent copper, 0.5 per cent magnesium, 0.5 per cent manganese, 0.3 per cent silicon, 0.2 per cent iron, with the remainder aluminium. The naturally aged version was covered by Air Ministry Specification DTD 18 issued in 1924, while artificially aged duralumin came under Specification DTD 111 in 1929. DTD 111 provided for slight reductions in 0.1 per cent proof stress and tensile strength.

The second group of aluminium alloys differs from duralumin chiefly by the introduction of 1 to 2 per cent of nickel, a high content of magnesium and possible variations in the amounts of copper, silicon and iron. `Y' alloy, the oldest member of the group, has a typical composition of. 4 per cent copper, 2 per cent nickel, 1.5 cent magnesium, the remainder being aluminium and was covered by Specification DTD 58A issued in 1927. Its most important property was its retention of strength at high temperatures, which meant that it was a particularly suitable material for aero engine pistons. Its use in airframe construction has been of a limited nature only. Research by Rolls-Royce and development by High Duty Alloys Ltd produced the `RR' series of alloys. Based on Y alloy, the RR alloys had some of the nickel replaced by iron and the copper reduced. One of the earliest of these alloys, RR56 had approximately half of the 2 per cent nickel replaced by iron, the copper content reduced from 4 to 2 per cent, and was used for forgings and extrusions in aero engines and airframes.

The third and latest group depends upon the inclusion of zinc and magnesium and their high strength. Covered by Specification DTD 363 issued in 1937, these alloys had a nominal composition: 2.5 per cent copper, 5 per cent zinc, 3 per cent magnesium and up to 1 per cent nickel. In modern versions of this alloy nickel has been eliminated and provision made for the addition of chromium and further amounts of manganese.

Aircraft structural aluminium.

Of the three basic structural materials, namely wood, steel and aluminium alloy, only wood is no longer of significance except in laminates for non-structural bulkheads, floorings and furnishings. Most modern aircraft still rely on modified forms of the high strength aerospace aluminium alloys which were introduced during the early part of the 20th century. Steels are used where high strength, high stiffness and wear resistance are required. Other materials, such as titanium and fibre-reinforced composites first used about 1950, are finding expanding uses in airframe construction.

Over the last several years, heavy-weight particle board and cabinet-based displays have lost their appeal and made way for the next innovation in displays systems - truss display systems. Today, exhibitors who want a display that looks substantial without the cost and assembly headache of cabinetry are choosing truss systems.

The Problem

Display systems that use materials such as cabinets and laminate panels to create larger island displays can cost exhibitors thousands in shipping and assembly costs alone for each show. On top of that, constant assembly and tear-down of these systems can leave them chipped, scratched and beat-up after just a few years.

The Solution

Today, while laminate panel systems are still widely used and requested, a new breed of aluminum frame displays can be a less-costly alternative. These systems are sleek, functional, and offer all of the amenities of laminate panel systems, including shelving, overhead lighting, and storage. Additionally, these systems offer versatile and striking visual options including backlit graphics, tension fabric graphics and areas for plasma screens and computer demos.

How They Can Maximize Your Budget

As an alternative to heavier wood displays, aluminum displays are much lighter in weight, making them far less costly to ship. Additionally, many aluminum frame displays assemble without the need for tools, saving money in set-up costs.

However, you need high-tech machinery for the process and you can produce shape indefinitely without spending a fortune in preparation costs. Hence, the process is totally economical. Roll-forming dies, in case you have heard about them they are costlier than extrusion die.

Aluminium extruded products have longer life than items made from steel or plastic. Besides, extrusion is meant to be the most environmentally friendly and economical solution. Aluminium as a metal even when not compared for its aluminium extrusion profiles and to weight properties. Even though it is light weight it has good strength.

Bifold doors are expensive but well worth the investment if you are considering renovations. Your house opens up to the garden and creates an amazing aesthetic when these doors are installed. It pays to exercise caution and care in a selection of the doors and consider various factors.


Price is not everything

The cheapest is not the best and the most expensive also is not necessarily the best. A Bifold door is not just panels put together; it is an entire system where design, engineering precision and choice of hardware plays an important in the door's looks and performance just as much as the bifold door installation does. Buying a well known international brand with local support is a good option.


Material of door

Bifolds can have wood, steel, uPVC or aluminum section frames. Wood can obstruct the view and be heavy. uPVC material can flex and distort which will affect the working of the door and there is a size limitation as well. Steel can be heavy. Aluminum is the best material for sections. It is relatively stable and does not tend to distort with temperature variations. From the maintenance point too aluminum scores because powder coated or natural anodized aluminum does not need frequent paint or maintenance.


Top hung or bottom rolling?

Bifold doors are available as top hung or bottom rolling types. If a strong enough beam is present then the top hung type is best because it does not collect leaves and debris and the frame conceals the mechanism from view.


Hardware and installation

Hardware is complex with bifold doors and must be precision engineered from quality materials besides being fitted just right during installation. Improper alignment can affect performance and cause stress on frames besides making the door hard to open and close. Quality systems have wheels that run on flat tracks and pivoted end doors for smooth movement even when the jamb does not allow much adjustment. Bifold door installation is important too when it comes to getting the threshold right to prevent rain seepage and yet creating a smooth transition that does not cause one to stub one's toes. Rain penetration is an important matter especially if the door is exposed. This is where the expertise of installer comes into play to provide a perfectly rebated rain-proof threshold. Security is another aspect to consider in the matter of bifold door hardware and a typical secure door would have multipoint locking system with shoot bolt for intermediate panels.


Single or double glazing


Energy conservation is important so double glazing is recommended. It will also provide some degree of acoustic insulation. Quality manufacturers provide U-values of 1.8w/sqmK or lower for such energy efficient bifold doors.


Screening

There are times when one may want an unimpeded view and there are times when one may want to shut out the light. Curtains are good but can impede the view. Venetian blinds that roll up all the way to the top may be ideal. If you choose a double glazed door then the blinds may be incorporated into the panels but at the cost of impeding the view. It is best to coordinate with the installer and clear this point as well before ordering a bifold door.

In our past articles I talked about all the steps required to properly replace your old wood sash windows with energy efficient vinyl windows. I told you how to measure for the new windows. Then we discussed the removal of the wood sashes and parting bead. Finally, I told you how to install, seal, and trim the vinyl replacement windows. But, what if those old windows in your home are made of aluminum instead of wood? Is the process the same? No, it's not the same at all. So, the next few articles are going to explain the differences between replacing wood windows versus aluminum windows.

When discussing the proper frame style for replacing the wood sash windows, I explained the difference between new construction frames versus replacement frames. When replacing aluminum windows, there is another option we have to consider regarding frame style. It's called a "retrofit" frame. Let's go over each frame type. First, we have the new construction frame with the nailing fin. If you choose to go this route, you have to remove the exterior around each window opening, pull out the nails holding the aluminum window to the studs, nail in the new vinyl window, apply flashing, caulk, and re-install the exterior around each window.(I get tired just talking about it!)In addition to being a whole lot of labor, you can run into major problems trying to install the exterior product around each window opening. If your home has stucco, you have to try and match the rest of the stucco. It can be done, but not by you. Even most professional stucco guys can't get a perfect match. What if you have wood siding? Well, you can cut away 2" of the siding around each window to get to the nail fin, then you can apply 1 X 2 or 1 X 3 trim around each window. Certainly not as much work as the stucco home, but probably more work than the average homeowner cares to tackle. What if each window is surrounded by brick? Let's not even go there! You would have to remove the bricks, then re-install them all when finished.

Trust me, you don't want to replace your old aluminum windows with new construction vinyl windows. You want to use either the replacement frame like the one used to replace the wood sash windows, or something called a retrofit frame, that is popular in the west where stucco is a common exterior. Since the procedure for measuring is the same regardless of the frame style chosen, this article will discuss the proper measuring procedure, and future articles will explain the difference in the installation process for replacement versus retrofit.

If you look at the portion of the aluminum frame that goes around the window opening into your surrounding walls, you will see three separate "legs" that form two pockets. The outside leg and the center leg form the first pocket. Your screen and stationary panel will be in this pocket. The center leg and inside leg form the second pocket, and your sliding panel is in that pocket. Find the "leg" that is the widest on all four sides. When measuring the width, run your tape measure from the widest leg on the left to the widest leg on the right. This should be the narrowest measurement. Then, subtract 3/8" from that measurement. This is the width of the replacement window. Measure the height the same way. When measuring the height, measure as close to the center of the window as possible. This is especially important on windows wider than six feet, because the top wood header has a tendency to sag over time, making the center of the opening the narrowest. You don't need to deduct 3/8" from the height like you did on the width. 1/4" is fine. These are the dimensions you use when ordering your vinyl window. If you have any picture windows(windows without a vent panel), there will only be two legs and one pocket. You still measure the same way.

Next week I will discuss whether your home is a candidate for retrofit frames or replacement frames...

Replacing Aluminum Frame Single Pane Windows

Aluminium Windows South Africa If you have a wonderful house with a great view of your garden or picture-postcard scenery spread gorgeously in front then you need doors that give an unimpeded view.
Consider the standard options like sliding doors. A part of the opening will always remain covered regardless of whether you use two partitions or three partitions. French doors simply do not suit large openings. The answer is custom bifold doors especially when the opening is large and an unrestricted view is desired. They save space and give an unhindered view of the exteriors.
The term bifold doors may be a misnomer since these doors are, in effect, made up of several panels that fold together like an accordion or concertina into a compact bunch of panels that do not take up much space and stay neatly on one side of the opening. You have a clear view. Standard panel sizes may range from 24 to 36 inches in width or customized to suit the width of the openings, which could be a better option in some cases. Custom bifold doors can help save space and the use of matching hardware means it will be a joy to operate.
Customization could take several forms. You can choose to have bifold doors with narrow or broader panels to suit design considerations and aesthetics of how the door will look when fully closed. Narrow panels do give a nice look but in some cases one may wish for a less obstructed view in which case broader panels serve the purpose. Cost will also vary. Obviously more panels lead to higher cost but the advantage is that opening and closing the bifolds will be easier when the door has narrow panels and they take up less space.
Where there are doors with glass the question of curtains or blinds always comes up. Here again customization helps when you choose double glazing panels with inbuilt blinds that are totally sealed within and can be opened or closed by sliding a magnetic latch. Such integrated bifold doors also help save space and present a neater appearance. Then there are small details that the installer and manufacturer will take care of such as using quality sliding tracks, pivots and hinges that integrate seamlessly into the aluminum frame. Another matter that necessitates customization is whether to place the track at the top or bottom. It is best to consult a reputed door supplier and installer and get a site inspection in order to get a customized fitting.
Bifold doors are not meant just as a partition between indoors and outdoors. They can also be used indoors to good effect as space savers between rooms. One can have a larger opening without the inconvenience of large door panels creating obstructions in confined spaces.
Bifold doors have several advantages such as ease of use, complete opening up of a room to the outside, security with the right set of hardware and energy efficiency. These advantages can be further enhanced by customizing the bifold panels along with glazing and hardware fittings. Alspec Aluminium Catalogue
