PVC
The first pillar of society, PVC has been the most common material for years which is also arguably the cheapest unlike wood or aluminum. Good insulation for thermal and acoustic performance or from an economic point of view taking advantage of good material performance. The quality to price ratio is excellent. As for the design, the color varies, it’s not just white. Choice of colors to bring out your creativity for your interior. White inside and RAL 7016 (anthracite gray) outside, on both sides or a PVC-ALUMINUM window. It all depends on your tastes. Very simple maintenance and a product that is both 100% recyclable
Wood
The material that lasts and returns to the market, old-fashioned oak for protected buildings or wood and aluminum windows on the outside. But more expensive than other materials. The wooden window is aesthetically more attractive than PVC or aluminum. It provides good thermal and sound insulation while being durable. A variety of RAL color choices or wood and wood-aluminum and more rigid maintenance.
Aluminum
The aluminum product is more chosen in premises but can also be by an owner who would like to have large bay windows or several window leaves. Good reputation for sound insulation but less for thermal insulation. Easier maintenance than wood and a 99% ecological product. Choice of RAL according to your choice.
