Crafted with an SBS rubberized asphalt layer bonded to a durable blue polypropylene film, this membrane features a siliconized release liner for easy application. Designed to deliver superior protection, it creates a complete barrier against air, moisture, vapor, and water. The material also self-seals around self-tapping screws or nails, ensuring long-lasting, reliable performance in demanding conditions.
Ideal for enhancing energy efficiency, this product helps block drafts and creates a secure, weather-resistant seal around windows, doors, and sheathing joints. It is also effective for sealing skylight openings and serving as reliable flashing in residential building projects.
