Social Housing, Low Rise: Refurbishment
Winner: Peel Avenue, Wirral

Peel Avenue, Wirral, is an estate of no-fines houses that have been totally modernised both internally and externally using external wall insulation. Wirral MBC wished to upgrade the thermal efficiency in line with Building Regulations, and their aesthetic appearance.

The PermaRock mineral fibre insulation system was installed, with scratch render on the upper floors and dry dash finishes. A U-value of 0.35 W/m²K was achieved with 70 mm of mineral wool: the use of the different finishes and a specially made profile incorporated into the design, allowed a ‘stepping’ feature between the two finishes for a modern appearance. New windows, doors and canopies were added.

The system designer was Permarock Products Ltd; the installer, E J Horrocks Ltd – both INCA members.
