3-Layer Joint Sealing System Product Properties:
• Temperature factor fRsi 0.92 to 0.96
• Good air-tightness
• Very good thermal insulation
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.
