Why Use Aluminium Windows

Aluminium Windows

When it comes to economy and flexibility of design, glass and aluminium have long been the preferred pairing for windows selected by builders and home remodeling contractors. However, there are many other reasons why aluminium windows are often chosen for new construction as well as window replacements. Aluminium windows will meet the requirements set down by the National Building Regulations as regards to deflection and glazing. Units can be produced and installed in patio enclosures, shop fronts, sliding doors, and individual windows, among other uses. They come in three basic varieties: top hung windows, side hung windows, and horizontal sliding windows.

Aluminium windows, however, have often been considered a poor choice as far as their energy efficiency. With new technology and new uses of the recycled material, aluminium actually can be an energy saver over its lifetime of use. Aluminium is among the most frequently recycled metals and requires only about five percent of the energy that was used to create it initially to put it to another use. In addition, windows made with aluminium frames now can meet or exceed energy conservation standards, particularly if paired with glass that includes a microscopic coating for energy savings. Aluminium itself can improve heat gain and loss through windows by as much as 60 percent compared with PVC vinyl and wooden units. The production of aluminium for windows leaves a lower carbon footprint than other materials. In one year, it can deliver three times the CO2 equivalent savings that was first required to produce the frames. As a result of these and other factors, aluminium frames can be much lower in price and more economical than other framing materials.

Even as it delivers good energy outcomes, aluminium frames are among the most durable and sturdiest of the materials available on the market. Aluminium can withstand a wide range of harsh weather conditions and is corrosion resistant. It will not warp, crack, split, or swell as can occur with other, lesser materials. During installation, there will need to be a 1/16-inch gap left between the aluminium and the wood frame to allow for expansion that humidity can cause.

Aluminium can be anodised or painted or left in its finished condition and its sturdy nature will remain unaltered, even if left untouched out in the desert for decades. As a result, aluminium requires very little maintenance other than periodic cleaning. The sturdiness of the material also makes it the perfect choice for large, expansive windows. It can handle the strain presented by all custom shapes and sizes. This is proven by the fact that architects of skyscrapers include aluminium windows in the design, never vinyl and certainly not wood. With very few exceptions, retail storefronts are made with aluminium-framed windows because aluminium can handle the large size of display windows. Even though fiberglass rivals aluminium in weather resistance, aluminium is most often selected because it does not need the upkeep fiberglass requires in the way of staining or painting. Windows that are truly large may require the glazing to be installed at the site, because of the difficulty in managing the weight and size of the glass.

In the painting department, there generally are more colour choices with aluminium to match almost any decor. Coloured vinyl windows are still not yet ready for the mass market, particularly in desert locations or other areas that are known for dry, hot weather. In fact, some vinyl producers will not even sell the white or tan variety in such areas because of the cracking and fading factor. Also, vinyl windows cannot absorb paint, so touch-ups are out of the question. On the other hand, black or dark coloured aluminium window frames can reliably stand up to the most severe weather conditions, in the desert or in other environments. Glass and aluminium also can be easily and cheaply painted if the owner has a change of colour choice. With vinyl, the colour it comes in is the colour it stays, save for fading.
