Don & Low explains how to specify membranes that perform where airtightness gets complicated.
Offsite and modular construction has revolutionised the way we build but hasn’t much changed the basic challenge of airtightness.
Factory-built modules arrive on site with controlled tolerances, yet the envelope still has to be made continuous across junctions, openings and interfaces that o amount of precision manufacturing can eliminate.
That’s where specification decisions made at the drawing stage either hold up or fall short.
The membrane is what much of this depends upon.
Specify something that requires multiple additional products to perform and you introduce risk at every joint, junction and opening. Specify well, and airtightness becomes something that’s largely built in from the start.
