Conclusions
These are the factors that have been taken into account in its design:
- The performance of the glass is fundamental since it occupies a large part of the surface of the opening. It should also be taken into account that, depending on the area where we are or even the use to which the building is going to be put, solar control may or may not be of interest.
- Maintaining permeability is key to energy savings. There is no point in installing a class 4 window when, after a few years, it becomes a class 2 window as it loses its airtightness. Aluminium with RPT stands out in this aspect over other materials.
- The thermal characteristics of the frame have very little influence on the total energy demand of a building. When choosing a frame, the following factors should be taken into account:
- Its function as a frame
- The low permeability it ensures over its entire service life
- The large amount of light entering through a small frame cross-section
- The finish
- Burglary and fire safety.
El aluminio RPT destaca con claridad en todos estos aspectos frente a los demás materiales además de ofrecer unas elevadas prestaciones térmicas.
RPT aluminium is clearly superior to other materials in all these respects, as well as offering high thermal performance.
