Passive Home Study

1. Weather Protection Layer

This layer needs to keep out wind and driving rain, but also be vapour-permeable.

2. Functional Layer

This layer is between the internal and external seal, and is used to produce sound and thermal insulation in connection areas. It must be filled completely.

3. Interior Layer

This layer needs to be air-tight and offer a higher level of resistance to vapour pressure than the outside seal. Products tested for moisture variability are an excellent way to achieve this combination.
