Thermal performance of windows and doors - Determination of thermal transmittance by hot box method - Part 1: Complete windows and doors
This part of ISO 12567 specifies a method to measure the thermal transmittance of a door or window system. This includes all effects of frames, sashes, shutters, door leaves and fittings.
It does not include:
- edge effects occurring outside the perimeter of the specimen;
- energy transfer due to solar radiation on the specimen;
- effects of air leakage through the specimen;
- roof windows and projecting products, where the glass layer projects beyond the cold side roof surface.
