Spray foam insulation from BASF used in conversion

BASF Polyurethanes has supplied Walltite spray foam insulation to provide a maximum thermal efficiency for the conversion of an 18th Century house into a modern family dwelling.

Rigg End Farm near the village of Rosedale is situated in the heart of the North Yorkshire Moors, a rural area exposed to the elements, which meant insulation and airtightness was crucial.

It was decided that the most suitable methos of stabilising the stone work with maximum insulation value was to use a spray foam system.

The builder working on the project contacted BASF Polyurethane approved foam contractor, UCS Insulation.

Applying Walltite means that the substrate does not require any preparation and no primer is necessary.

On this project the stonework only needed dusting off prior to application.

Walltite was then spray applied to the internal walls between the timber studwork and fixed slightly off the wall to eliminate the potential for cold bridging.

Any high spots were then trimmed back with a wood saw before attaching plasterboard to the studwork.

Approximately 100m of Walltite was applied within two and a half days.

The finished walls achieve their target U value of 0.26W/mk, well within Part L building regulations.

A minimal insulation thickness of 85mm was achieved in most areas with little reduction in room size, enabling the owner to retain the character of the original building elements.

Walltite is sustainable over the life span of the building and can even prolong the buildings life as it protects against premature deterioration of building materials.
