Palisade Synthetic Underlayment is 6 times lighter and 30 times stronger than asphalt felt.

PALISADE™ synthetic roofing underlayment is truly a revolutionary advanced technology product specifically designed for the most wide ranging and toughest steep slope roofing application challenges.

Possessing breakthrough, category leading STRONGHOLD™ skid resistant technology1, PALISADE™ is engineered to provide the roofer the most advanced synthetic underlayment steep slope surface traction product on the marketplace today. STRONGHOLD™ is designed for the most demanding steep slope conditions of wet & dusty surface environments. Unlike smooth or hard polymer surfaced underlayments which become extremely slippery when wet or dusty2, STRONGHOLD™ skid resistant technology utilizes a highly engineered raised surface profile pattern of soft and resilient rubberized polymer dots which act as grip/anchor points which deliver category leading skid resistant performance in wet/dusty conditions3. This superior skid resistant technology also results in improved ability to hold roof loaded items such as tile, shingle packs, underlayment rolls; all without the use of hard grit particles that increase product weight, easily dislodge, and scratch metal roofing systems.

Designed for additional roofer safety in mind, PALISADE™ also possesses skid resistant technology on the underside, thus reducing the incidence of slippage between the underlayment and deck. PALISADE™ is 100% FELT FREE and designed with high strength polymers. This delivers 6X lighter and 30X greater tear strength compared to 30 lb. asphalt felt underlayment. This incredible strength delivers reduced blow-offs during exposed roof conditions and reduced tear away which plagues felt paper (6:1 cap nail pull strength vs. 30 lb. felt), as well as reduced installation & roof surface traffic damage. PALISADE™ is light weight (10 squares per 40 lb. roll), and comes in wide width and 290 ft. roll length for enhanced productivity. Now you can do more jobs faster with fewer rolls, fewer laps and fewer fasteners.

To deliver a complete capability single roll product for incredible versatility, PALISADE™ has been designed with advanced flame retardant polymer formulation technology1, and is CLASS A rated (ASTM E108/UL790) when used in combination with metal, concrete and clay tile, composition shingle, slate, or non fire retardant wood shake roofing systems4.

PALISADE™ also possesses advanced UV polymer technology to deliver up to 6 months exposure protection before the primary roofing covering has to be installed. This provides roofer and customer outstanding job scheduling flexibility and security during extended exposed roof conditions, and avoids the need for tarps. This exposure performance eliminates the old technology felt paper practice of having to immediately cover over felt underlayment because of the chronic occurrence of wrinkling, blow offs and UV damage, especially in high wind and/or wet conditions.

For demanding high temperature metal roofing systems such as zinc and copper, PALISADE™ is designed with high temperature polymers, providing a 300°F rated product. Furthermore, being a 100% felt free synthetic polymer product free of asphalt oils, PALISADE™ does not require the use of rosin paper or other separator sheets between the underlayment and primary metal roofing underside as required with asphalt felt underlayments (added cost savings).

To provide roofers a cool product to work with, as well as a cooler roof, PALISADE™ has been engineered with a unique KOOL BLUE™ high reflectance color technology1 designed for low surface temperature, low energy (heat up) absorption, as well as low glare. This results in PALISADE™ being 8X cooler than black felt underlayment.

Unlike asphalt felt underlayments which leach oils at elevated temperatures, and become slick and messy to work with, PALISADE™ is 100% oil free, and provides roofers a cooler, cleaner, and safer product to work with. PALISADE™ is 100% polymer synthetic, so unlike asphalt felt underlayments, PALISADE™ has extremely low water absorption, which means it lays flatter for reduced buckling/wrinkling; a problem which fundamentally plagues felt paper underlayments. The use of high temperature, high strength polymers in PALISADE™ results in superb flexibility of unrolling/handling in a wide temperature range (-70° to 300°). As a polymer synthetic PALISADE™ does not support mold growth.

PALISADE™ is ICC ESR-1847 building code approved nationally, as well as 2005 Florida Building Code, High Velocity Hurricane Zone Approved (HVHZ) for use under roofing tile... the ONLY synthetic underlayment on the market today meeting this toughest of building code standards (FL-5325.1).

PALISADE™ with revolutionary STRONGHOLD™ skid resistant technology represents the most advanced synthetic roofing underlayment on the marketplace today. PALISADE™ combines several advanced polymer technologies to deliver superior safety, advanced performance, and tremendous value to the most demanding roofing contractors.
