Functional and user-friendly types of windows and doors are very important aspects to consider when designing a building. Aluminum windows can be seen not only in school or office buildings. They perfectly present themselves as an element of modern single-family houses in combination with subdued colors of the facade.
Aluminum’s flexibility and susceptibility to formation makes it possible to form windows of various untypical sizes and shapes, e.g. trapeze. The same property affects the fact that the window profiles can be narrower, and thus, it determines the aesthetic appearance of the windows, which thus appear slimmer and have a larger glazing surface. Additionally, narrow profiles optically enlarge even small windows. It is also worth adding that aluminum frames can also be much wider and allow even extremely large and heavy glazing to be embedded. The color range of aluminum profiles is virtually unlimited. They can be powder coated in any RAL color or anodized. Choosing aluminum is a decision almost for life. Aluminum is a material you do not really need to look after. Its durability and the fact that the coating on its surface is UV-resistant make aluminum systems very easy to maintain. A small amount of water, a sponge and neutral soap, which does not cause scratches, is enough to clean aluminum systems. This is a considerable simplification compared to wooden systems that have to be renovated and re-painted every few years.
Thermal insulation is the basic parameter classifying window joinery constructions. Thanks to years of work of joinery manufacturers and development of material engineering, however, enormous progress has been made and today aluminum windows provide excellent thermal insulation and meet the expectations of even the most demanding investors. The appropriate level of insulation is ensured by placing a thermal separator between the inner and outer profile.
Reynaers Aluminium achieved very good thermal insulation parameters by introducing a thermal separator made of glass-fiber-reinforced polyamide into the aluminum profile. The wider the stripes, the higher the degree of insulation. The choice of material is not a coincidence – polyamide provides excellent mechanical properties and, unlike PVC, is recyclable, which is part of Reynaers Aluminium’s environmental friendliness.
For the most demanding projects, Reynaers Aluminium has developed MasterLine 8 and MasterLine 10 window and door systems. They utilize a thermal separator with even better properties than polyamide of noryl. In the HI+ variant (highest insulation level), the separator is completed with a radiation-reflective coating and additionally sealed with foam inserts, which constitute an additional thermal barrier.
Currently, Profal can produce aluminum windows with a heat transfer coefficient (for the whole window) below 0.8-1.0 W/(m2K), which means that they can also be used in energy-efficient construction.
