Tyvek Membrane and Brackets QA Checklist

This quality assurance checklist supports installers and contractors during the installation of Tyvek breathable membranes, helping hand brackets, and vertical rails. Verify structure handover, membrane orientation, and required overlaps including 100 mm horizontal, 150 mm vertical, and 150–300 mm at corners. Confirm double-sided Tyvek tape between laps and that all joints are fully sealed. Inspect helping hand bracket sizing for correct cavity depth, confirm thermal isolators are in place, and check fixings against the specified schedule. Capture photos and notes, raise corrective actions with priorities and due dates, and complete installer, A2O, and client sign-offs. Export reports as PDF, Word, Excel, or web link.
