Private-Label Membrane Tape and Housewrap Accessories
Combine membrane roll requirements with a separate accessory specification. European breather membrane joint tape and US housewrap seam tape / WRB seam tape inquiries should identify the membrane, substrate and installation detail before sample approval.
Review membrane seam and window flashing tape options and butyl sealing tape for concealed laps and transitions. Seam tape is not automatically a flashing product, and compatibility must be confirmed for the chosen construction.
- Specify width, roll length, adhesive, backing and release liner.
- Confirm brand artwork, labels, carton quantities and export packing.
- Approve samples and the relevant product data before bulk production; confirm MOQ and lead time in the quotation.
