When applying a multi-layer bituminous roofing system on PIR IKO enertherm ALU insulation, specific considerations must be followed to ensure correct installation. IKO recommends the following installation method to guarantee the durability and waterproofing performance of the roof:
Simultaneous installation of base and top layer
Due to the vapor pressure-distributing properties of the base layer applied on PIR IKO enertherm ALU insulation, it is recommended to install the top layer immediately after placing the base layer (IKO base quadra SA).
This simultaneous installation offers the following benefits:
- Immediate sealing of the base layer overlaps
Guaranteed wind stability of the bituminous waterproofing system through thermal activation of the self-adhesive quadra dots on the base layer
The base layer alone does not provide long-term waterproofing
Tip:
During cold periods, the base layer should be stored at a temperature above 10°C to facilitate easier installation.
