Expert Verdict — Reviewed by the SuperArbor Pro Desk
A polyester slipsheet is essential between XPS insulation and membrane in inverted roofs to prevent abrasion and blocks from drifting. Roll it out smooth and lapped per JM specs before the membrane goes down. The 12 ft. width helps minimize seams on large commercial decks.
Follow roof site fall-protection requirements and keep the fabric secured against wind during installation.
Add the JM Polyester Mat Protection Sheet 12 ft. x 100 ft. roll to your next inverted roof assembly.
