Reinforced crawlspace liner, wall liner, and install accessories built to order as one system.
VaporDefender™ is a 15 mil scrim-reinforced, UV-stabilized Class I vapor barrier program with floor liner, wall liner, seam tape, wall tape, 8'6" term bars, and masonry screws—so crews can buy a complete crawlspace package in one order.
Current VaporDefender product line
Built around the crawlspace package most contractors actually need: floor liner, wall liner, and the wall/seam accessories that finish the job.
Why VaporDefender fits the contractor lane
Clean spec position
15 mil scrim-reinforced film laminate, white/white finish, UV stabilization, and Class I vapor barrier performance keep the line easy to explain on bids and installs.
Better ordering flow
Floor rolls, wall liner, tapes, term bars, and screws are structured as real products instead of one-off add-ons, so the system can be bought in one cart.
