Product Details

Altaron synthetic roofing underlayment is a 3-layer thermo-bonded PP non-woven fabric on top and bottom layer for protection and reinforcement, micro-porous PE film in the middle layer as breathable membrane.

It’s an indispensable water-resistant or waterproof barrier, installed directly onto your roof deck beneath all other roofing materials. As the preferred choice for most roofing professionals today, synthetic underlayment is a highly engineered solution designed to provide the crucial, added layer of protection that shingles alone cannot match.

Keeping pace with technological advancements, Altaron New Materials offers a lightweight synthetic underlayment sheet designed as a superior alternative to traditional asphalt-saturated felt. It is built to stand strong as a moisture barrier against rain, wind, and snow, ensuring your roof deck is protected from all inclement weather.

Key Features

● Superior Strength and Stability: Our synthetic underlayment features a woven polymeric scrim for increased strength. The product's highly engineered, coated woven construction is extremely durable, delivering superior tear resistance whether due to walking traffic or prolonged UV breakdown.

● Enhanced Roof Longevity: It acts as a robust secondary weather barrier, effectively helping to fortify roofs from wind-driven rain and elemental exposure. This moisture-resistant water barrier is designed to enhance the overall life of the roof.

● Optimized Installation Safety: A specialized, textured top surface fabric is treated with a super elastomer to create an advanced anti-skid surface. This dramatically improves walkability during installation and ensures reduced slippage between the underlayment and the roof sheathing.

● Application Versatility: The product can be mechanically fastened to several different substrates, making Altaron's Synthetic Roof Underlayment an excellent solution for both new construction and re-roofing applications.

Altaron Synthetic Roof Underlayment is a water barrier built to stand strong when it is needed the most, providing dependable, long-term protection for your structure.
