With current building cost, the best longterm material protection is worth the cost. The outdoor environment is not a safe place for many types of building materials. Water always finds a way. And in the open air horizontal deck surface applications with wood joist framing, this is no exception. Nor are the wood and composites decking surfaces placed over the joist framing. In the short-term, no worries. All is good. But if more than 5-10 years of 100% quality material conditions are preferred, then check this out.
Would you like to more life to you exterior decking projects—30 to 40 year MAINTENANCE FREE—then consider this insurance policy.
And you say, "but there is a solution that has been used for 10-12 years". Yes, the joist tape. This was once a product used only in the window installation industry until someone suggested using it for capping the top of joist. Yes this does provide some limited protection, depending on the type of material used in the joist tape. But its protection is limited to the top of the joist for a limited time, but no protection to the bottom of the decking. And remember, water rolls in all directions; it rolls off of the deck boards, under the deck boards and off of the tape and under the joist tape edge. Water finds a way!
Introducing the maximum solution and long term building material insurance, FrameVent®. Here is a product designed for this specific purpose that doubles the protection. The fingers of the product support the decking surface material while allowing a small air gap to dry out the bottom surface of the decking material. The bottom of the FrameVent® includes a high quality butyl tape to cap the top of the joist and self-seal the deck screws. And with a tapered drip edge, more water is shed to the outside face of the deck. ALL PROBLEMS SOLVED. Get some insurance for your next project!
