Surecav25 saves 25mm of cavity and results in 1.25% of extra internal space on an average two storey three-bedroom house.
If the house sells for £280,000, it is the equivalent of £3,500 of extra value for a cost of only the SureCav25!
A cavity left in this condition is asking for trouble, with contaminated wall ties allowing moisture
to transfer to the inner leaf.
