Relevant guides

Thermal bridges in basements

Thermal bridges in basements. Start by documenting dew point and surface temperature, condition of the substrate and hidden organic materials. The purpose is to understand the building condition and constraints before choosing products, finishes or a work sequence.

Insulating basement walls

Insulating basement walls. Start by documenting condition of the substrate, dew point and surface temperature and hidden organic materials. The purpose is to understand the building condition and constraints before choosing products, finishes or a work sequence.

Condensation on basement windows

Condensation on basement windows. Start by documenting dew point and surface temperature, condition of the substrate and actual air-change path. The purpose is to understand the building condition and constraints before choosing products, finishes or a work sequence.
