WHAT DO WE MEAN BY THE TERM ARE THE “ENERGY” ALUMINUM FRAMES?
The energy (thermally-cut) frames stand out from the conventional ones, thanks to the use of a special insulating material (polyamide) which is a bad heat conductor) that distinguishes the window profiles in two parts, both exterior and interior. In this way, high thermal insulation is achieved, with considerable benefits also for soundproofing.
Thermal insulation of the windows (coefficient of thermal conductivity) is measured in W / m2k. This factor defines the amount of heat in Watt per unit of time that a 1m2 frame can penetrate when the temperature difference between its two surfaces (in-out) is 1 degree (1 ° C).
An energy aluminium frame also requires the corresponding glass (glass pane). A glass pane and aluminum profiles have different coefficients. The coefficient of thermal permeability of the aluminum profile is called Uf (U Frame – frame) and the coefficient of the glass is called Ug (U Glass – glass). Combined, they give the Uw coefficient (Window U – window), which refers to the frame as a whole, precisely because the glass and the window profile occupy a different surface each time depending on the dimension of the window frame (bathroom window, balcony door, etc.).
In summary, the benefits of heat-shrinking frames are the following:
- Energy saving
- Reduction of cooling / heating costs
- Resistant to extreme weather conditions
- Minimizing of water vapour penetration on the inner surface of the profiles
- Low air permeability
- Delivers transvalue on the property (rental / sale)
