Product Information


The Owens Corning Deck Defense Premiuim Synthetic Underlayment is composed of 100 percent engineered polyolefin with a specially coated, textured, and engineered top layer that provides traction. Deck Defense provides long-term moisture protection and acts as a secondary water-shedding barrier that is also non-absorbant. When exposed to water intrusion, deck defense reduces it. This synthetic underlayment also helps to shield your home during a roof installation and can stay intact during high winds. Deck Defense is constructed to reduce chances of tearing that can cause leaks, and the durable synthetic construction also helps with tear resistance when walked on. Plus, it can protect your roof deck for up to 6 months of exposure to UV. Owens Corning backs Deck Defense Synthetic Underlayment with a 30-year limited warranty.
