Partial Fill Cavity Wall Insulation
Insulation for partial fill cavity walls.
Partial fill cavity wall insulation. Some builders started to built in a solid board around 1985 onwards this board was approx 30mm and fitted against the inner leaf of the cavity at this time cavities increased from 75mm to 100mm. In these cases this left a 70mm space of the cavity with no insulation. Partial fill cavity wall insulation built after 1985. The thermal performance of cavity walls may be improved by installing ballytherm insulation within the cavity.
This method is well suited to new build projects. The properties of ballytherm insulation match those required for this application. Typically a 50mm residual cavity is required to be maintained between the outer face of the cavity insulation and the inner face of the outer leaf. Insulating a solid ground floor below the ground bearing concrete slab can be done using either pir insulation boards or eps insulation boards.
Using a steel frame inner leaf and masonry outer leaf. A partial fill cavity features thermal insulation secured back to the inner sfs frame leaving a cavity of air between the insulation and the masonry outer leaf and can be used on buildings of any height. Its low thermal conductivity minimises the.
