Vapour-permeable membranes: coordinating the wall design

Discuss a vapour-permeable membrane as part of the wall's documented moisture strategy. Ask the designer to identify the exact classification and layer sequence required for the project before selecting a wrap and installation accessories.
Define the selection
Use a drawing of the proposed layer sequence when asking technical questions. Identify the exact membrane and compatible accessories in the order, and refer unresolved moisture or installation details to the responsible designer or manufacturer.
Check before comparing products
- Project moisture strategy and classification.
- Position within the wall build-up.
- Compatible tapes, laps and penetrations.
Build a material list that can be checked
Record the selected product name or SKU, each required size and the quantity for each work area. Use the actual listed coverage when estimating packs or boards, and confirm the allowance with your installer. Include compatible accessories and keep a copy of the agreed selections.
