A system was needed that was simple and quick to install - whilst delivering reliable thermal performance. The Knauf Insulation ThermoShell IWI system was the natural choice.

The use of thermally engineered insulated studs (EcoStud) eliminates the thermal bridging issue associated with traditional systems incorporating timber and metal studs. The extruded polystyrene content (XPS) of EcoStuds provide a high level of thermal and moisture resistance, as well as offering a high level of compressive strength.

The system incorporates Earthwool® EcoBatts, high performance, water repellent glass mineral wool slabs, that are friction fitted between the EcoStuds to completely fill the available space. The slabs are made with a formaldehyde-free binder called ECOSE Technology. This is derived from rapidly renewable, bio-based materials, which reduces embodied energy and delivers superior environmental sustainability. It is naturally brown in colour as there are no artificial colours or dyes added and it produces a ‘super softer’, odourless and easier to handle insulation.

Fuel poverty is a big issue in Glasgow and in Scotland as a whole, and the IWI system has made an appreciable difference to the residents. Robert Tamburrini, CEO of NG Homes comments: “NG Homes has a proven track record of investing in our property and this insulation will make an appreciable difference for our residents. It will improve the energy efficiency of the homes, make them warmer and reduce fuel bills.

The project is the largest IWI installation in the UK and is expected to make significant savings for residents in heating bills (the Energy Saving Trust advises that this can be up to £460 per year for solid wall insulation).

Information received from tenant’s state that it’s made a vast difference from day one of the installation. Several residents have commented that they are setting their heating to a much lower level and some have even switched it off completely. One resident stated the significant reduction in road noise once they had the system installed.

The project has been so successful in fact that residents that were initially resistant to the installation are now coming forward to have it installed – which is a fantastic endorsement of both the Knauf Insulation ThermoShell IWI System and the installation by City Technical.
