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.

Extrusion is the process to change the structure and shape of different metals. Some of the metals that are commonly extruded include aluminium, copper, lead, magnesium, zinc, titanium etc.

As aluminium is malleable in nature, it is easy to extrude. Specific dies are used for the aluminium extrusion process. These steel dies have opening of the desired shapes. Primarily, this process can be of two types - hot and cold. For hot process, precise heating is very important. It is done above the aluminium's recrystallization temperature. While, cold process is done at room temperature or near room temperature.

To obtain superior quality and improved surface finished aluminium extrusions, accurate temperate and its monitoring is vital. The finishing increases the durability, strength and its appearance. In the process, a billet is heated at the temperature of 400 C to 500 C and is pushed through the die under pressure to create preferred profiles. The shape, structure and specifications vary according to the requirements of the product, customers and its application.

The company's manufacturing aluminium extrusions prefer extrusion process over welding as it gives product with constant cross section. The strength and lightweight (strength-to-weight ratio) of this metal makes it popular among customers. Its several other properties gives it edge over other metals. These are cost-effective, corrosion-resistive, flexible and durable.

The prime source of aluminium is bauxite ore and Feldspar to some extent. Some of the fields where the this metal's extruded shapes are used include transportation, building and construction to name a few.

The former is widely available, has impressive properties, and is affordable, light weight, can withstand high temperatures and so on. And above all the aluminum extrusion involved in getting different shapes and forms for suppliers is cost-effective and simple. Both in US and Europe building industry and the telecom as well is highly dependent on aluminum extruded products. These products find a number of usages and are used in many applications.

So, what is aluminum extrusion? This is a process through which aluminum is given certain shapes and forms. It starts with the hot cylindrical billet of aluminum which is pushed through a shaped die. The billet is cut from DC cast log and placed in heated container (450°C - 500°C). When pushed through the die the metal flows through the steel die. The die is placed at the other end of the container. Now, once the log passes it produces a section, this can be cut into shapes either in long length or short. The section is cuts according to the customized demands of the clients since the log is meant to be used for any particular industry. In certain extrusion process rectangular shaped billets. In this process only wide section sized extrusions are produced. This again depends according the demands of the supplier.

Aluminum extrusion is done for several kinds of industry and these aluminum extruded products are very commonly used in building industry. In this industry you can use aluminum in prefabricated houses/building structures, window and door frame systems, curtain walling, roofing and exterior cladding, and shop fronts. Besides, they also find place in the telecommunication and transport industry. In transport industry aluminum extruded products are found in rail vehicles, marine applications, airframes and for vehicles on the road.

So, what makes aluminum so popular? It is the versatility and the flexibility of the material that turns in so popular. Since aluminum is high temperature resistance and is corrosion resistant as well it is used to make utensils and is also used on transport vehicles. Besides, it is strong even though it is light weight and thus it is used in airframes.

So, if you are out there still deciding on selecting aluminum extruded products or some other metal you can give your votes to this metal as it is affordable and durable as well. No more second thoughts to this go ahead with aluminum extrusion and the products.

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.

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.

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...
