To form an internal wall insulation system solution at the Whitley Bay property, British Gypsum’s GypLyner UNIVERSAL isolated metal frame wall lining system was installed. This was ideal for refurbishing the existing poor quality walls and also provided a clear cavity to accommodate cabling and heating pipes. Gyproc ThermaLine Super, a high performance thermal laminate plasterboard, was screw-fixed onto the GypLyner UNIVERSAL system and in order to prevent any air movement, Saint-Gobain Isover Acoustic Partition Roll (APR) 1200 was added into the cavity.
Comparing data collected pre and post insulation, the trial found that yearly gas use has gone down by 36.7 per cent, which equates to a 1098 kg reduction in CO2 emissions from the property and a saving for the homeowner of £269 over the course of a year.
Ian Gordon, commercial manager at MITIE property services who managed the installation, said: “As is typical with properties of this age, the building is made up of solid walls making the most common retrofit method of insulation, cavity wall, impossible. The Victorian architecture on the front façade of this terraced property also meant external insulation was unsuitable, as it would have impacted on the overall appearance and planning permission would have had to be sought, which can cause its own challenges and can often lead to a delay.
“For this property, the walls were insulated internally using a solution consisting of British Gypsum GypLyner UNIVERSAL metal walling system and 60mm of British Gypsum Gyproc ThermaLine Super. As a cost-effective, general purpose system, GypLyner UNIVERSAL was ideal for this project. Gyproc ThermaLine Super was a key product for this project because of its high level of thermal performance. It is also good value for money, which was an added benefit.
“Before the insulation, the owner of the home had frequently used an electric fire in addition to her central heating to maintain a comfortable living temperature. After internal wall insulation the same temperature could be maintained with central heating alone. The home also got warmer much more quickly, reducing the evening heating period by one hour.”
Gyproc ThermaLine Super is a thermal laminate plasterboard used for wall refurbishment and room-in-the-roof applications where a substantial upgrade in thermal insulation is required. GypLyner UNIVERSAL wall lining system is a virtually independent metal frame drylining that is suitable for all internal non-loadbearing applications.
