An Alutrix 600 vapour barrier membrane was installed directly onto the substrate of all roof areas, providing both effective protection against water vapour ingress and an air-tight layer. This was followed by cut-to-fall PIR insulation and the RESITRIX® EPDM membrane.

Specification for the leisure aspect of the project needed to consider the performance, loading capabilities and root resistance of the roof build-up. RESITRIX®’s unique EPDM and bituminous composition provided an ideal durable and puncture-resistant waterproofing layer with an extended service life, excellent root resistance, and absence of any harmful plasticisers that could jeopardise the planting.

For the project’s residential phase, the chosen waterproofing system needed to be robust enough for the installation of solar panels. RESITRIX® was an ideal choice because the unique combination of EPDM and bituminous layers in a single ply membrane delivers both flexibility with durability. EPDM has now been certified to provide a service life in excess of 70 years by SKZ, which ensures that the roof covering will have a service life in excess of that of the solar PV, while offering low maintenance weather protection.

RESITRIX® was also installed on the dormer roof areas, where intricate interfaces were formed with the pitched roof sections.
