Aluminium is the most popular choice for double glazing to mid 80`s, when it has around 60% of the market share. Since the advent of PVC windows on the market, however, the market share of aluminum windows started to fail. Since 2003rd less than 17% of sales of windows are aluminium made. There are many reasons to explain the decline in its popularity – and there are some very good reasons for choosing aluminum windows instead of PVC or wooden ones.
Aluminium windows are fire-and earthquake-resistant. They are very resistant to temperature changes.
Aluminium as a material does not change over the years. You can even sell it for around a third of its original price if you want to change your windows for good.
The aluminium is a preferred material for interior doors, as it requires a lot cheaper hardware, than it is required for doors, made of PVC.
Aluminium is so strong that it can be used for making roofs, facades, winter gardens and many more. The strength of the material makes it preferable in the construction of protective doors and fire barriers, and many others structures in which the strength of the material is of very great importance for their resistance.
PVC windows are another great option for your home as the windows` profile is made of a material with a low coefficient of thermal conductivity, than aluminium ones. Therefore aluminum profile retains less heat than PVC windows. Let`s put it this way – because of its low thermal conductivity, the PVC profile helps avoid condensation helps keep the house warm in the winter and cool in the summertime.
50% of the thermal losses of a house, come from the walls, floors and ceilings, and the other 50% come exactly from the windows.
