Layout of the proposed fl oorplan comes together
at the same time eliminating air leakage – more commonly known as draughts. “Up to 40% of a buildings heat loss can be attributed to air leakage,” said Shearer, “so it’s vital that reducing air leakage is included in any programme of measures to improve a building’s thermal performance.” H2Foam Lite is installed using a pressurised gun system. Foams are applied as a two-component mixture that come together forming a foam that expands 100-fold within seconds, closing off all gaps, service holes
and hard to get to spaces that conventional insulation materials fail to reach.
Low environmental impact Unlike the polyurethane foams of 20 years ago, modern spray foams such as H2Foam Lite uses water as the blowing agent. This means that the reaction between the two components produces a small amount of CO2 which causes the foam to expand. Cells of the foam burst and the CO2 is replaced by air. From an environmental perspective, H2
External walls were lined with timber studwork to accept insulation
Foam Lite has a Global Warming Potential [GWP]of 1 and an Ozone Depletion Potential of 0 [Zero]
Insulation was applied to the inside of all external walls as well as the roof structure. Walls were sprayed to a thickness of 165mm between timber studwork and to a thickness of 320 mm within the pitched roof. Studwork dividing walls within the building were also insulated to provide a high level of both thermal and acoustic insulation.
Spray foam converts Cleveden has created a development of seven luxury 1, 2 & 3 bed apartments over four fl oors with ground fl oor parking and lift access to fl oors above. There is approximately 1000 sqm of fl oor area overall. Commenting on the use of spray foam insulation,
Alex McGurk said; “Speed
of installation and minimal waste were key factors in our decision to use spray foam. That and the overall lower cost of spray foam, because we didn’t need to commit trades to the time-consuming process of cutting and fi tting rigid board type insulation really clinched it. We are spray- foam converts!”
Cleveden are progressing well with the Castlehead Church repurposing project and anticipate completing in winter 2022. For
