Compare
Compare the approach.
Not just the board.
The right choice depends on the position in the roof, additional load and evidence for the full build-up.
| Aspect | DEK | WEER | VLOEI |
|---|---|---|---|
| Principle | Thin mineral cover board | Weather-resistant mineral board | Mineral coating approach |
| Position | Below new waterproofing | Following application confirmation | To be determined for each system |
| Installation | Dry board installation | Boards, joints and fixings | Mix, apply and cure |
| Key consideration | Roof load and system combination | Moisture, joints and drainage | Adhesion, movement and installation |
| Project proposal | On request | On request | On request |
Specification, quantity and delivery date are tailored to your project and confirmed in the quotation. A material classification does not approve every roof build-up.
