Why use a breathable
façade membrane

Breathable vertical façade membranes behind cladding
The protective shield for closed and open rear-ventilated façades
Performance
Besides it's high fire safety Euroclass A2,s1-d0 premium façade membrane Stamisol Safe One forms an effective and safe weather protection in the rear ventilation level of closed and open façades. The membrane acts like the human skin: it is open to diffusion, protects and serves as a climatic regulator. Resistance to UV rays, moisture and heat is indispensable, especially for open, rear-ventilated façades.
Thus, the thermal insulation is reliable for protection against weathering over a long period of time, supporting energy efficiency and reducing the risk of condensation, removing residual moisture to the outside via the membrane.
Proven coating technologies and the highest quality of raw materials, coupled to uncompromising Swiss quality, make Stamisol façade membranes high quality, extremely durable and resistant to aging, which is manifested in a comprehensive lifetime guarantee for Euroclass A2 supported by a product 10-years warranty.
Framed external walls
England and Wales Building Regulations Approved Document C for resistance to moisture says in Clause 5.17, that when a vapour open membrane is needed, the membrane has to be resistant to water:
“Any framed external wall will meet the requirement if the cladding is separated from the insulation or sheathing by vented and drained cavity with a membrane that is vapour open, but resists the passage of liquid water, on the inside of the cavity”.
Why use a façade breather membrane?

Made for enlarging buildings' longevity
- Building moisture is moved from the inside to the outside, which extends the life span of the building
- No moisture in the membrane guarantees a dry and functional thermal insulation
- Stops fungal build
- The penetration of sun UV is reduced by reflection
- No cooling down of the insulation by wind/air
- Protection from fire, smoke and hot droplets (fire rating Euroclass A2,s1-d0)
