VAPOUR CONTROL LAYER WITH VARIABLE PERMEABILITY FOR WALLS AND ROOFS CLIMA CONTROL 105
The vapour control layer that adapts to roof layers and wall build-ups in timber and masonry
CLIMA CONTROL 105 is a variable vapour permeability membrane for vapour control in roof layers, walls and roofs in timber, concrete and masonry. It acts as a vapour control layer when the construction build-up is dry — Sd up to 20 m — and as a breathable membrane when it is humid — Sd down to 0.1 m — automatically adapting to the structure's hygrothermal conditions. The special transparent PA film makes it easier to identify the studs when installing directly onto timber frame structures. Certified to EN 13984.
Technical data for CLIMA CONTROL 105 smart vapour control layer
With a variable Sd value from 0.1 to 20 m (EN 1931 / EN ISO 12572), CLIMA CONTROL 105 is the ideal smart vapour barrier for the energy refurbishment of existing buildings, where wall build-ups often contain residual moisture that a fixed-Sd vapour barrier cannot manage.
Key technical specifications (EN 13984):
— Variable water vapour permeability Sd: 0.1–20 m
— Tensile strength MD/CD: > 175/150 N/50 mm (EN 12311-2)
— Elongation MD/CD: > 60/60%
— Resistance to nail tearing MD/CD: > 140/150 N
— Air permeability: < 0.02 m³/(m²h50Pa) (EN 12114)
— Reaction to fire: Class E (EN 13501-1)
— Temperature resistance: -40/+80 °C · Indirect UV exposure: 2 weeks
Installed on the internal side of walls and roofs using staples, DOUBLE BAND, SUPRA BAND.
Smart vapour control layer for timber walls: how does CLIMA CONTROL 105 work?
Within a timber wall build-up, relative humidity varies with the seasons. CLIMA CONTROL 105 responds by increasing its resistance to vapour diffusion in winter — up to Sd 20 m — and reducing it in summer to Sd 0.1 m, promoting the drying of the wall build-up. This cycle prevents moisture from accumulating within the insulation materials.
Roof layers in timber construction: where is the vapour control layer installed?
Within the roof layers, the vapour control layer is installed on the warm internal side, between the internal lining and the insulation. In this position, CLIMA CONTROL 105 limits vapour migration towards the outside during winter and promotes it during summer, protecting the insulation from the build-up of interstitial condensation in accordance with EN ISO 13788.
Vapour control layer for the energy refurbishment of existing buildings: why choose a smart vapour control membrane?
In refurbishment projects, existing wall build-ups often contain residual moisture. A fixed-Sd vapour barrier would trap this moisture within the construction. With its variable Sd range of 0.1–20 m, CLIMA CONTROL 105 promotes the drying of the build-up during the warmer months without compromising winter protection.

Description
The application surface must be dry, free of dust and grease. Surface elements must be removed so that the membrane is not damaged during application.
Once applied, the product allows for easy visibility of powder tracer markings and underlying mounting holes.
Recommended use: This product is intended for installation on the interior side of the building envelope and is guaranteed to withstand only indirect UV exposure for a maximum duration of 2 weeks.
Suitable for energy retrofit applications due to its ability to dynamically adapt to relative humidity. It is breathable when internal relative humidity is too high, and serves as a vapour control layer when internal humidity is at suitable levels.
Installation: Unroll the membrane and seal using tape such as: INVISI BAND, FLEXY BAND, SPEEDY BAND o EASY BAND.
Ensure that the overlap between the membranes is at least 15 cm to achieve an optimal seal.
Each layer must be fixed to the substrate with a mechanical fastening device to ensure installation stability.
To ensure correct and professional installation, the use of a nail sealing point is required.
Further details regarding installation can be found in the specific instructions provided by the supplier.
