45 Vinyl Membrane Detail Drawings for Decks after 45 Years

Duradek Detail Drawings

Vinyl membrane detail drawings for decks can help AEC professionals easily incorporate waterproof outdoor living space into their designs.

Installation details for vinyl decks are a critical component of successful waterproofing. Especially when it comes to waterproofing flat roof decks over living space, reliable waterproofing depends on more than a high-quality product. The actual performance is all in the details and the skills of the installing contractor.

Since 1974, over 150 million square feet of Duradek vinyl membranes have been installed. With that much experience with a niche product and specialty application on decks over living space, Duradek has firmly established itself as the leader in the vinyl decking industry.

Our “roofing grade” details meet industry and government standards but more importantly have me the test of time.

In honor of 45 years in business, here are 45 of our most popular detail drawings for specifying and installing Duradek vinyl membranes.
