Overview

BUILT FOR THE ELEMENTS

FAQ

COMMON QUESTIONS

For most facade, cladding and window perimeter joints we specify UV-stable hybrid polymer (MS / SMP) sealants. They are paintable, weather resistant and accommodate high movement. Polyurethane is preferred for trafficable concrete joints.

Backing rod sets the correct sealant depth and stops the sealant bonding to the back of the joint. Two-sided adhesion lets the sealant stretch and compress as the building moves without tearing.

Yes. Our team works safely at height with the appropriate tickets and access equipment, including EWPs, for soffits, parapets and multi-storey facades.
