Αluminium frames are the solution that will provide you with very robust doors and windows and, therefore, increased security and long-term durability.
In case of high temperature fluctuations, they do not warp in the long term, a fact that is very important in regions with a lot of sunshine and high temperatures during the summer. This is why they offer highly exact dimensions that remain unaltered and are not prone to expansions and contractions. Thus, maximum tightness against air and water and a perfect fit between the frame and the window’s sash is achieved.
Also, aluminium frames’ robustness allows for the creation of large spans for maximum natural light, with no danger of frames bending or twisting, as is often the case with other, weaker materials. Even in very thin profiles, a double sash aluminium door can bear more than 1000 kilos!
Lastly, in case of fire, aluminium windows & doors don’t help it spread and in fact, they limit it. Aluminium, in contrast to other materials, absorbs and removes a large portion of the heat produced by fires. When aluminium does melt, at 660 degrees Celsius, it slows down the speed of fire, without creating flammable or toxic gasses.
