The KM-31NP GY part of MASZCZYK is a high-strength, fire-resistant, waterproof, self-adhesive, noise-dampening roof membrane system for roofs. It is composed of a membrane consisting of a mineral-reinforced steatite-base and a fleece carrier, as well as a self-adhesive bituminous tape. It is designed to offer better acoustic insulation and thermal insulation performance than conventional systems, while providing excellent weather protection and waterproofing. The KM-31NP GY is extremely stable under high temperatures, and has higher flame-resistance than other materials commonly used in roofing systems. It is also resistant to tears, punctures, and chemical corrosion, making it a durable and reliable material for long-term use.
