Deck Joist & Seam Tapes

Extend the life of your deck with our American-made deck joist and seam tapes. Our tapes, such as deck joist protection tape and deck flashing tape, create a waterproof barrier to protect wooden joists and beams from moisture and rot. Easy to apply and built to withstand the elements, our butyl deck tape ensures a long-lasting and durably sound deck.
