What Stands Out
Superior Thickness
With a robust 12 mil thickness, this underlayment provides exceptional durability and protection against moisture, enhancing the lifespan of your flooring investments.
Large Coverage Area
Covers 937.5 square feet, making it ideal for larger projects. This extensive coverage minimizes waste and ensures consistent performance across your entire flooring installation.
Moisture Barrier
Designed as a synthetic underlayment, it effectively prevents moisture infiltration, reducing the risk of mold and mildew, thus safeguarding your living space.
Product Details
- The CertainTeed Diamond Deck Synthetic Underlayment is a high performance, polymer-based layer that is reinforced with gauze and is water-resistant. This underlayment layer is meant to be placed beneath asphalt roofing shingles, wood shingles and shakes, metal shingles and panels, concrete tile or slate. Compared to standard asphalt felt underlayment, Diamond Deck Roof Underlayment has remarkable dimensional stability that eliminates the possibility of hygro-expansion wrinkles. The standard asphalt felt underlayment can cause distasteful wrinkles on the finished roof, because it can become very wrinkled when it picks up moisture. Diamond Deck has an extra-large length and width for a speedy application, and it has a special top surface treatment that provides superb slip resistance, even when it is wet. Please Note: Walking or crawling on any roof surface can be dangerous, especially when wet or snow/ice-covered.
