Kooltherm K108 Cavity Board has been installed as part of the Great Yorkshire Build charity initiative to provide a bespoke rebound therapy centre at the Brooklands School.
The SEND school provides specialist facilities for pupils aged between 4-19 with a range of complex needs. The state-of-the-art therapy building will house a number of trampolines, allowing students to take part in fun, therapeutic exercise which can also help them to develop their coordination and alleviate anxiety.Â
On the centre, a 75 mm thickness was fitted with a 50 mm cavity. This allowed the walls to achieve a U-value of 0.18 W/m2K with a total cavity depth of just 125 mm, maximising the floor space without compromising on thermal performance.Â
To support project teams, Kingspan Insulation has produced guides covering indicative Psi-values for the use of Kooltherm K108. This guidance covers the majority of common junction types and can support projects to meet the tougher energy efficiency requirements within the updated version of
The work has also included the refurbishment of several key classroom spaces and the construction of a multi-sensory room.
In addition to delivering high quality facilities for students, the scheme has been designed to limit ongoing operational costs for the school. For this reason, the project team adopted a fabric-first approach for the centre, using Kooltherm K108 within the blockwork cavity walls.Â
Kooltherm K108 has a thermal conductivity of just 0.019 W/mK across all thicknesses. The residual cavity from using a partial fill insulation board helps to limit moisture penetration, whilst also limiting the overall cavity depth.
