Dog Ear Joist Flashing System
Protect Your Deck’s Frame from the Elements
When it rains, it pours and your deck’s frame is just sitting there, soaking it up. Don’t let the deluge compromise your frame’s structural integrity and drain your wallet. That’s where DEK Drain’s dog ear joist flashing system comes in. It can help you extend the life of your deck, without requiring the commitment of a complete under deck drainage system.
Named for its resemblance to a dog’s droopy ears, our flashing system is installed without panels. Even so, it provides optimum protection for exposed joists.
The Joist Flashing System at a Glance
- The dog ear system uses the same materials as DEK Drain’s comprehensive TOPSIDE® and UNDERSIDE® systems.
- Specifically, three layers of specially formulated, 45 mil. rubber membrane are installed over each joist. This provides exceptional protection against the elements.
- Additionally, layers also contract around the shaft of deck board fasteners to prevent leakage.
- Furthermore, the rubber substrate resists moisture damage, sun exposure, acidic leaf debris, and saltwater spray. Even so, it retains its protective features in fluctuating temperatures.
- Best of all, it allows for simple, swift upgrades at a later date. That means you can easily transition to a full-fledged water diversion system. From there, you can completely waterproof your under-deck area for use as an outdoor living or storage space.
