Calculation model Isothermal

Description

PVC-frame with reinforcement inside the blind-frame. Pane thickness: 48 mm (4/18/4/18/4), rebatedepth: 19 mm, spacer: TGI-Spacer P

Explanation

The window U-values were calculated for the test window size of 1.23 m× 1.48 m with Ug = 0.90 W/(m2 K).If a higher quality glazing is used, the window U-values will improve as follows:

Glazing Ug = 0.90 0.74 0.70 0.64 W/(m2 K)↓ ↓ ↓ ↓

Window UW = 1.00 0.89 0.86 0.82 W/(m2 K)

Transparent building components are classified into efficiency classes depending on the heat lossesthrough the opaque part. The frame U-Values, frame widths, thermal bridges at the glazing edge, andthe glazing edge lengths are included in these heat losses. A more detailed report of the calculationsperformed in the context of certification is available from the manufacturer.

The Passive House Institute has defined international component criteria for seven climate zones. Inprinciple, components which have been certified for climate zones with higher requirements may alsobe used in climates with less stringent requirements. In a particular climate zone it may make senseto use a component of a higher thermal quality which has been certified for a climate zone with morestringent requirements.
