ROCKWOOL insulation system brings sustainability to Merseyside development

Two energy efficient external wall insulation systems developed by ROCKWOOL have been specified by One Vision Housing as part of a major Merseyside refurbishment scheme to transform existing social housing into sustainable homes.

Funded by European Regional Development Fund (ERDF) through the Renewables and Energy Efficiency in Community Housing (REECH) initiative, the recently refurbished Hornby Flats Estate is a low rise development featuring eight, three storey buildings in a garden environment that originally dates back to 1950.

One Vision Housing invested £2.4 million to provide a range of energy efficient benefits, as well as extend the life of the 96 flats and improve living conditions for residents. The project involved a significant upgrade to the building fabric for design, aesthetics and technical performance and was completed in September 2015.

Lead architects HLP worked closely with One Vision Housing to meet its demand that real brickwork would still be visible to remain sympathetic with the surrounding traditional brick Victorian terraces. The solution by HLP was based on over-cladding the flats with external wall insulation that combined thermally robust detailing with contemporary classical architecture.

The ROCKWOOL solution

ROCKWOOL’s BBA-approved BrickShield system, an insulated external wall cladding with a brick finish, was used in combination with the ROCKWELL REDArt Silicone render system to deliver the required performance and finish. 

Developed in partnership with Ibstock, the ROCKWOOL BrickShield system comprises a ROCKWOOL insulation board that is bonded to the exterior face of the wall with BrickShield Adhesive, mechanically fixed with thermally broken BrickShield Insulating Wall Anchors. 

BrickShield Natural Clay Brick Slips from Ibstock are then site-bonded to the insulation with BrickShield Adhesive and joints pointed with BrickShield BrickPoint for a traditional brick appearance finish.

By using stone wool insulation, manufactured with alternative grains to achieve the correct adhesion surfaces, the fire-resistant Brickshield system offers a sustainable and environmentally-friendly solution. 

The system was used in combination with REDArt Silicone external wall insulation, as well as ROCKWOOL FS Mortar 2 base coat and a top coat of REDArt render applied in a cream coloured silicone finish to complete the project.
