How should my roof insulation be built up?

The secret to good insulation is in choosing the materials and the installation. Because good insulation is more than just the material used. Without a good sub-roof and moisture barrier, the insulation is worthless.

The sub-roof:

• protects insulation against snow and rain
• must be waterproof
• also protects against wind
• increases the insulation value of the roof

The insulation material:

Various insulation materials are suitable for a sound insulation of your attic floor or sloping roof.

The moisture barrier:

• serves as a finishing layer above the insulation material
• is an airtight protective layer that prevents damp air from penetrating the insulation
• has perfect glued seams and is attached to the walls with an adhesive
• is very important: if damp air condenses in insulation, it reduces the insulation value of the material.
