Swistherm External Wall Insulation (EWI) from Alumasc Facades, has been part of the major refurbishment of Seagate Court in East Wittering.
Managed by the Seagate Court Management Company Ltd, the complex comprises four four-storey blocks of private residential flats, boasting a stunning coastal location overlooking the seafront.
Although the scheme was originally solid cavity wall construction, the relentless climate and saltwater air had resulted in significant erosion to the exteriors, requiring the management company to embark on a complete refurbishment programme.
Sally Ratcliff, of Harrington Design Architects, explains:
“Sea salt had started to erode the concrete exterior and the brickwork needing repointing. We wanted a solution that would protect the building and improve its appearance and had initially considered weatherboarding before realising that the Alumasc Swistherm EWI system would meet and exceed our requirements.
“The home-owners at Seagate Court now have a sleek, stylish and structurally sound building and are also benefitting from warmer and more energy efficient homes with an improved U-Value of 0.28 w/m2k from the original 0.6 w/m2k.”
2200 square metres of Swistherm EWI was installed to all exterior facades of the four blocks by Alumasc’s Registered Installer Primars Coatings of Middlesex. The system was insulated with a 90mm EPS and finished with Alumasc’s high performance silicone render.
The project presented the installer with a number of issues as Contracts Director, Julien Turner, explains:
“One of the main challenges was ensuring that we kept meticulously to the architect’s design. The building was quite complex in terms of ashlar grooves at each floor level and the detailing under and around the balconies, but the ease of installing Swistherm addressed these circumstances.”
The specification of the Swistherm system meant that as well as improving the structure and thermal performance of the block, its aesthetic appearance was also transformed by the silicone render finish.
All Alumasc EWI systems are BBA approved, fully warranted and offer a range of design and specification options available across many building types.
