Puretan 20: cavity wall insulation
Puretan 20 is a two-component polyurethane system designed for the on-site insulation of masonry cavities.
It is applied using dedicated equipment directly inside the cavity, through holes drilled into the masonry. The product is particularly suitable for infill walls made of brick, concrete, iron or similar materials, with cavities at least 5 cm thick.
Main benefits
- Contributes to the thermal insulation of external walls, improving indoor comfort.
- Helps reduce noise transmission.
- Reduces the formation of moving air layers inside the cavity.
- Promotes outward vapour migration, allowing the wall to breathe.
- Makes the structure more compact by connecting the walls of the cavity.
- Completely seals the treated cavities.
- Physiologically inert, insoluble and non-metabolisable.
