Protan’s Telescopic Tube Washers and Fastener combination provide a thermal break and practically eliminates cold bridging. The washer and fastener combination ensures costs can remain economical and a more positive fixing is ensured.
Only Telescopic Tube Washers & Fasteners supplied and approved by Protan can be used for Protan membrane attachment, as they are a critical part of our design and warranty package.
The type of fastener combination will depend on the substrate and will be determined by Protan Technical Services.
