Aluminium Windows Cape Town

When double glazing first became a popular window choice in the 1960s, most frames were made of aluminum. Aluminum remained the most popular choice for framing double glazing windows through the mid-1980s, when it held over 60% of the market. Since the introduction of PVC window framing, the market share of aluminum framed windows has dropped steadily. As of 2003, less than 17% of windows sold were aluminum framed. There are many reasons for the drop in popularity - and still some good reasons for choosing aluminum over PVC or wood frames.

The early popularity of aluminum was based on price and convenience. Aluminum was far less expensive than wood, the only other choice for window framing in the early years of double glazing. In addition, aluminum is easily extruded in the shapes and lengths needed to frame windows of any shape or size. It's strong, durable and very close to maintenance free.

Aluminum frames do have one significant drawback, however. Aluminum is an excellent conductor of heat and cold. It's such a good conductor, in fact, that in colder temperatures, frost often forms on interior surfaces of the windows close to the aluminum joints. The end result is windows that are significantly less able to conserve heat and energy than those framed in other materials.

PVCu was introduced in the mid-80s as a choice for framing double glazing windows, and immediately began to climb in popularity. When compared with aluminum frames, PVCu was less expensive, and more energy conservative. It can't match the strength of aluminum, however, and there are security concerns with its use. In addition, the introduction of 'thermal breaks' reduces the heat conductivity (measured in U values) of aluminum framed windows significantly. By fitting a less conductive material between the panes of the window as a sort of 'bridge' between the glass, manufacturers can bring the U value of aluminum framed double glazed windows within conservation standards.

The main selling points for aluminum window frames, then, were:

1. Strength - aluminum framed windows are far less prone to warping. The aluminum withstands weather well, needs no painting and forms strong, rigid window frames that will fit for far longer than wood frames.

2. Cost - aluminum frames are far less expensive than wood frames. They are easier to manufacture, and the material is less expensive to begin with. On the other hand, the introduction of PVC has largely negated the advantage of cost. Far lower in price, and with more efficient heating, PVC has become the material of choice for framing double glazing windows.

3. Ease of maintenance - As opposed to wood, which is subject to warping and decay and needs repainting every 3-5 years, aluminum is virtually maintenance free. It never needs painting, doesn't rot or warp, and is rigid and strong enough to bear the load of window lintels with minimal reinforcement.

4. Security - Because of the tight fit possible with aluminum framed double glazed windows, they were - and still are - the choice where security is a paramount concern. It's very difficult to 'pop' an aluminum framed window from its frame if it's properly fitted.

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.

Aluminium Extrusion Manufacturing Process

Aluminium Windows

When purchasing your aluminum profile system, it is important to use aluminum profile systems that represent the latest in technological progress. They are available and many have highly competitive prices.

What is an aluminum profile system?

Aluminum profile systems are extruded shapes (tubing, bar stock, angles, rods, ducts, channels, air supply systems, pipe racks, etc.) made from aluminum. Extrusion is a process by which different aluminum shapes are formed from a cylindrical hydraulic press. The press forces the aluminum through the die and the extruded aluminum results in the desire shape.

What is the history of aluminum extrusions?

Patented in 1970, the extrusion process was first used to make lead pipes. Lead, copper, iron, and steel have a much longer history than aluminum, which was first identified in 1807.

At first aluminum was considered more precious than gold. However, with the advent of the smelting process and the modern hot extrusion process in the 1880's, it became extremely affordable. Aluminum, the metal most used for extrusion, can now be used with both hot and cold extrusion processes.

What are the benefits of an aluminum profile system?

There are many reasons why an aluminum system is preferred over other tooling. Some of the most important reasons are that it is not only affordable, but also durable, lightweight, and corrosion resistant - and many of the components are reusable, thus lowering the cost.

Respected manufacturers of aluminum profile promise shortened lead times, which is very important to most customers. This is possible because fewer tools are required to produce the final product, the designs are simple, and no welding or painting is required.

These manufacturers usually have a large stock of shapes and finishes on hand. If a customer needs a shape different that what is normally carried, that shape can be custom-made.

What are the uses of aluminum profile systems?

After World War II, when aluminum extrusions were used in the manufacturing of aircraft and other military uses, new uses were quickly found to be applicable for other industries. Aluminum extrusion is even used in the space industry.

If you are not familiar with the uses of aluminum profile in today's world, you might be surprised to know that they are used in computers, fixtures, everyday household appliances, home furnishings and interior design, power tools, and window frames.

In the world of manufacturing, aluminum systems are used in conveyor frames, fixtures, construction, protective barriers, work tables, electrical components, work bins, car radiators, automobile body and frame components, drive shafts and cylinder liners, and in special and series machines.

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.

Advanced Aluminum Profile Systems Available on the Market

Aluminium Window Frames Catalogue

Having lived with all three types of windows and patio doors in the past three years, I feel that I am an 'expert user' when it comes to opening and closing in each medium: wood, pvc and aluminium.

First, the novice's choice: wood. It looks great, feels warm, can be stained a medium or dark shade or painted any colour of the spectrum. It's an age-old medium so what can go wrong? The main problems are humidity and strong sunlight.

There are varying qualities of wood on offer, depending on your budget. A moderately-priced pair of French doors on a south-facing house wall suffered a degree of warping, creating gaps that had to be plugged each winter in an attempt to keep the cold draughts at bay whereas, in warmer damp circumstances, the door had to be forcibly pushed and pulled back into its aperture.

Two good summers and the four coats of varnish had virtually vapourised, revealing cracking wood that needed nourishing and protecting from the next couple of years' weather.

Second, the double-glazing salesman's special offer: PVC. Overpriced by a couple of well-known companies who then discount by 50% if you hesitate, PVC is also available in varying qualities. At the higher end of the market, the frames are often reinforced with metal.

Generally with more features than wooden doors and windows, PVC should not require much more than a quick wipe with a damp cloth for the first few years and its looks are therefore easier to maintain. We have some PVC French Doors from the lower price range. As value for money, they are quite good but an element of trust is lacking in terms of defence against determined intruders. They feel floppy and flimsy when opening and closing and there's a knack to locking and unlocking them successfully. We have older PVC doors from the higher price range and, whilst more sturdy (reinforced with metal) they are looking a tad ratty.

The PVC windows screeched with wind whistling through, like semi-detached tinnitus.

Thirdly and finally, the long term investment: powder-coated aluminium frames. If you are fed up with sanding down wooden frames and considering the easy option of PVC or coated aluminium, particularly for a wide opening with multi-folding doors. Consider whether PVC is up to the task of substituting for the wall of your house.

Stand back and look through closed doors at the difference between PVC and aluminium - it is very noticeable. With PVC, there are windows of scenery between wide areas of plastic (two frames together might measure between 8 and 10 inches, 20 to 25cms) so the doors block up to 20 per cent of the potential view and light-source.
 
Aluminium frames on bifolding doors from manufacturer SunSeeker Doors, being stronger, are only about 2 inches or 5 centimeters. The profile is also considerably smaller so the doors use far less space than PVC or wood when folded back. For those who want color, several options are available to order, the most popular (after standard white) are: Grey, blue, green, brown and silver. Aluminium Frames are more expensive than cheap PVC or wood but prices are comparable with the better quality PVC doors. Is aluminum worth the extra cost? If you want the "wow" factor, strength, longevity, maximum living space and the most panoramic view,Yes.
