Product Summary
Polyglass membranes and waterproofing products are reinforced with polyester and/or fiberglass mat offering superior flexibility, excellent tensile strength and dimensional stability and is intended to be used as the primary weathering surface in new or re-roofing applications.
The POLYSTICK self-Adhesive family of products consists of homogeneous rubberized asphalt waterproofing adhesive in conjunction with APP or SBS compound. The rubberized asphalt seals around correctly installed nails on the weathering surface.
Construction and Materials
Polyglass offers a range of high-performance self-adhering modified bitumen underlayments designed for superior weather protection for roofing systems. These products serve as a critical component in a complete roofing assembly, providing an extra layer of defense against water intrusion, particularly in demanding roof areas.
The construction of Polyglass self-adhering underlayments typically involves a robust reinforcement scrim that provides dimensional stability and tear strength. This scrim is then coated with a proprietary blend of asphalt modified with polymers, such as Styrene-Butadiene-Styrene (SBS) or Atactic Polypropylene (APP). The polymer modification enhances the asphalt's flexibility, low-temperature performance, and resistance to weathering.
A key feature of these underlayments is their self-adhering application. The underside of the membrane is coated with a high-tack adhesive system, allowing for quick and easy installation without the need for torches, adhesives, or mechanical fasteners in most applications. This significantly reduces installation time and labor costs while minimizing the risk of application errors. The self-adhering lap provides a reliable seal, preventing wind-driven rain and ice dams from penetrating the roof deck.
The top surface of the underlayment is typically surfaced with granular materials or film to provide a walkable surface and protection from UV exposure prior to the installation of the final roofing material. The bottom surface is protected by a removable release film that is peeled away just before the membrane is applied to the roof deck.
Materials Used:
- Reinforcement: Typically a polyester or fiberglass scrim for dimensional stability and tear resistance.
- Bitumen Blend: Asphalt modified with polymers (SBS or APP) for enhanced flexibility, elasticity, and weatherability.
- Adhesive System: A high-tack, self-adhering compound for quick and secure bonding.
- Release Film: A silicone-coated film to protect the adhesive during storage and handling, which is removed during installation.
- Surfacing: Granules or film on the top surface for walkability and UV protection.
Polyglass underlayments are engineered to meet stringent industry standards and provide long-term performance in a variety of climates. They are suitable for use under shingles, metal roofing, tile, and other common roofing materials.
Features and Benefits
Polyglass offers a comprehensive line of high-performance ice and water barrier membranes designed to provide superior protection against water infiltration in roofing systems. These products are engineered to safeguard structures from the damaging effects of ice dams and heavy rainfall, ensuring long-term durability and building envelope integrity.
Polyglass Ice & Water Barrier Features and Benefits
- Exceptional Waterproofing: Our ice and water barriers create a robust seal that effectively prevents water from migrating beneath roofing materials, particularly in vulnerable areas such as eaves, valleys, and penetrations. This significantly reduces the risk of structural damage, mold growth, and costly repairs.
- Self-Adhering Technology: Many Polyglass ice and water barriers feature advanced self-adhering technology. This allows for quick and easy installation without the need for torches or hot asphalt, minimizing labor time and associated hazards. The strong adhesion ensures a secure bond to the substrate, preventing wind uplift and water penetration.
- High-Temperature Stability: Engineered to withstand extreme temperature fluctuations, these membranes maintain their integrity and performance throughout the year, from scorching summer days to freezing winter conditions. This resilience prevents blistering, cracking, and degradation.
- Durability and Puncture Resistance: Constructed with robust materials, Polyglass ice and water barriers offer excellent resistance to punctures and tears. This durability is crucial during installation and provides an added layer of protection against accidental damage.
- Enhanced Roof Longevity: By creating a reliable secondary water defense, our ice and water barriers significantly extend the lifespan of your overall roofing system. They protect the underlying roof deck from moisture-related decay, saving on future replacement costs.
- Versatile Applications: These membranes are suitable for a wide range of roofing applications, including sloped roofs, metal roofing, and as part of a complete roofing system with asphalt shingles, shakes, tile, and more.
- Ease of Handling and Application: Designed for contractor convenience, Polyglass ice and water barriers are easy to cut, handle, and position. The split-back release film on self-adhering products simplifies installation and reduces waste.
Core Product Advantages
The core advantages of Polyglass ice and water barriers lie in their ability to deliver superior, long-lasting protection against water damage while simplifying the installation process for contractors. Their self-adhering nature, high-temperature performance, and inherent durability combine to create a premium barrier that significantly enhances the reliability and lifespan of any sloped roofing system. This translates to reduced callbacks, increased contractor efficiency, and greater peace of mind for building owners.
Options-Styles
Polyglass offers a range of high-performance ice and water barrier membranes designed for superior weatherization and protection against water intrusion. These products are essential for safeguarding structures against the damaging effects of ice dams and wind-driven rain, particularly in vulnerable areas like eaves, valleys, and dormers.
The available options generally fall under the category of self-adhering membranes, providing a robust and reliable seal without the need for torches or adhesives. This installation method contributes to safety and efficiency on the job site.
Product Styles and Features
- Self-Adhering Technology: The core feature across most Polyglass ice and water barrier products is their self-adhering nature. This allows for quick and easy application, creating a strong bond to the roof deck or underlayment.
- High Traction Surface: Many of these membranes incorporate a specially designed top surface that enhances walkability and slip resistance. This is crucial for installer safety during the roofing process, especially on steep slopes or in challenging weather conditions.
- Split Backing: A split-release film backing is a common feature, making it easier for installers to remove the protective liner and accurately position the membrane.
- Excellent Adhesion: These products are formulated for superior adhesion to a variety of substrates, ensuring a secure and long-lasting seal that resists lifting and peeling.
- Water and Ice Dam Protection: Specifically engineered to prevent water from migrating under roofing materials, providing a critical barrier against ice dams and wind-driven rain.
- Durability and Longevity: Constructed with high-quality materials, these membranes are built to withstand harsh weather elements and maintain their protective properties over the lifespan of the roof system.
Common Product Lines (Illustrative examples based on typical industry offerings, specific product names may vary)
While specific product names and formulations can evolve, Polyglass typically offers variations that cater to different performance needs and application requirements. These often include:
- Standard Self-Adhering Ice & Water Barriers: These provide foundational protection for typical residential and commercial roofing applications.
- High-Temperature Rated Membranes: Designed to perform reliably in hotter climates or over underlayments that generate significant heat, preventing softening and adhesion failure.
- Enhanced Traction Membranes: Featuring more aggressive surface textures for maximum slip resistance in demanding environments.
The selection of the appropriate Polyglass ice and water barrier should consider factors such as climate, roof slope, roofing material being installed, and local building codes. Proper installation according to manufacturer guidelines is paramount to ensure optimal performance and protection.
