JOIST GUARD provides waterproof protection for joists that prevents rotting of structural timber under exterior floors, such as decks and balconies. Is a self-adhesive membrane composed of elastomeric bitumen. The surface is made of polyethylene; the underside is covered with a silicone release film. Four-inch rolls are ideal for two-inch-wide joists, while nine-inch rolls are used on double joists at the perimeter of the structure and to seal the joint between the wall of the house and the deck.
