Product Expert Notes
This base sheet suits contractors who want torch-free dry-in on multi-ply jobs. Roll it onto a clean, dry, approved substrate, align with the pre-printed laylines, and press or roll seams fully for adhesion. Because it tolerates up to 90 days of exposure, it works well when scheduling gaps between dry-in and the field membrane. Confirm substrate approval with the Polyglass product data sheet before installation.
Roofing membrane work carries fall and surface hazards; follow the manufacturer's data sheet and applicable job-site safety practices during installation.
Order the Polyglass Elastoflex SA V self-adhered SBS base sheet for a fast, torch-free dry-in on your next multi-ply roofing job.
