Home Product News Kooltherm external wall board improves energy efficiency

Kingspan Kooltherm K5 External Wall Board has been specified as part of an innovative whole building retrofit system installed on a Solihull social housing development, dramatically reducing its energy requirements.

The low-rise block of six flats was upgraded to meet the demanding EnerPHit Standard using a revolutionary off-site, wrap-around large-scale (OWLS) retrofit solution – the Beattie Passive TCosy – which was installed around the existing building to create a highly insulated envelope, limiting thermal bridges. Kingspan Kooltherm K5 External Wall Board was selected as a key system component because of its ability to deliver premium thermal performance relative to its thickness.

Ron Beattie, managing director of Beattie Passive, explained: “Using the Kingspan Kooltherm K5 External Wall Board within our retrofit system has helped us to achieve U-values of just 0.099 W/m2K for the walls and an airtightness test result of 0.93 air changes per hour (ach) @ 50 Pa. These calculations mean that the Retrofit system easily meets EnerPHit Standards.”
