Dermabit 4250 is environmentally friendly, made with materials that minimize impact and feature a long lifespan, contributing to reduced waste.

Compared to other membranes, Dermabit 4250 provides superior performance through its advanced APP formulation and polyester reinforcement, ensuring better flexibility, durability, and ease of installation.

Dermabit 4250 (3250 5250) is an APP (Atactic Polypropylene) modified bituminous waterproofing membrane. It is designed for superior waterproofing and is reinforced with materials like polyester or fibreglass. This membrane is suitable for various applications, including roofing and wall waterproofing.

Typically, APP membranes like Dermabit are available in various thicknesses, such as 2 mm, 3 mm, and 4 mm. The choice of thickness depends on the specific application requirements, such as base, mid, or cap layers in a multi-layer system.

APP membranes are known for their high tensile strength, excellent UV resistance, and flexibility at low temperatures. They are also highly resistant to weathering and provide 100% impermeability, ensuring no leakage when applied correctly.

APP membranes are typically applied using a torching method, where the underside of the membrane is heated to bond it to the substrate. It is crucial to ensure the surface is clean and free of oils or chemicals before application.

APP membranes offer enhanced bitumen performance, excellent UV resistance, and superior tensile strength. They are durable, resistant to rapid temperature changes, and provide flexibility even in cold environments, making them suitable for a wide range of applications.

Dermabit APP membranes are typically reinforced with non-woven polyester fabric or fibreglass, which provides dimensional stability and mechanical strength.

Yes, APP membranes are suitable for extreme temperatures. They maintain their flexibility at low temperatures and resist flow at high temperatures, making them ideal for both cold and hot climates.

Yes, APP membranes can be exposed to UV radiation. They are designed with UV-resistant properties, which allow them to withstand prolonged exposure to sunlight without significant degradation.
