Underlayment foil Techno Membrane 170 75m2/roll 170g/m2 TECHNOSIM

Techno Membrane 165 underlayment is a highly effective three-layer membrane designed to protect pitched roofs from moisture, snow and dust, while allowing the free passage of water vapor. It guarantees reliability and security in every respect, providing long-lasting and effective protection of the structure without compromising the energy comfort of the premises.

Designed with attention to mechanical strength, the membrane has high tear and tensile strength, while its unique structure improves energy savings and minimizes the risk of condensation. It is suitable for all ventilated and non-ventilated roofs, providing optimal vapor permeability, durability and protection in various climatic conditions.

Purpose

• Secondary protection of pitched roofs under the external coating
• Suitable for ventilated and non-ventilated roof structures
