The foundation of the
ALUPRO W77 window and door system consists of combined profiles made up of two aluminum profiles connected by thermal breaks of 42 mm in windows and 34 mm indoors, made of Low Lambda PA 66 GF25 polyamide reinforced with fibreglass from TECHNOFORM. Thermal bridges have a lower thermal conductivity of 0.21 W/mK compared to standard polyamide, which has a thermal conductivity of 0.3 W/mK.
The window structure made from the
ALUPRO W77 system with a double-glazed unit
6i-16Ar-4-14Ar-6i has been tested and received a thermal transmittance value of
1,14 м2*К/Вт.
