Description
AIRSTOP DIVA+ is a fabric reinforced vapour retarder building membrane for airtightness of your building envelope. With highly variable moisture permeability (SD value from 0.5 to 30 meters) this high performance membrane, is ideal for Passivhaus and energy efficient builds of all sorts.
Width: 1.5m
Length: 50m
Area: 75m²
SD Value: 0.5m to 30m (highly variable SD value)
Application Area (Internal):
- Internal Walls
- Ceilings
Purpose in an Airtight Building Envelope:
As a highly moisture variable internal membrane, AIRSTOP DIVA+ primary roles are: Airtightness & Moisture Control.
- Moisture Control:
AIRSTOP DIVA+ resistance to vapour diffusion varies according to air humidity.
This dynamic vapour permeability ensures that building components remain dry throughout the four seasons, reducing any condensation, mold, rot. And overall improving building’s health and energy efficiency. - Airtightness:
While being open to moisture, AIRSTOP DIVA+ provides excellent airtightness, enabling the building envelope to pass blower door tests with ease, when installed correctly.
Advantages:
- Variable vapour permeability
- Tough and durable, highly tear resistant
- Printed cutting lines for easy and neat application
