Problem Solved

• Location: Wolverhampton
• Architect: Tweedale
• Completion date: 10th January 2012

WALLTITE® Polyurethane spray foam insulation system has been used in a refurbishment project at the University of Wolverhampton to significantly improve the U-values of the existing pitched roof. Total Insulations carried out the work using 145mm of WALLTITE CL 100 spray applied polyurethane foam insulation to achieve the specified U-value requirement of 0.16W/m²K

Various issues had to be considered, particularly with reference to minimising the levels of condensation within the roof space. WALLTITE CL 100 spray applied polyurethane foam insulation was able to meet the architect’s specification by exceeding the condensation risk requirements as the cold surface area is now sufficiently insulated.

Tweedale, the architects for the refurbishment project, ideally required a solution that would avoid any external access to the roof. Andrew Hall, the architect leading the project explains: ‘Access was a main factor for this project as the refurbishment work had to be carried out on a three story building. The WALLTITE CL 100 spray applied polyurethane foam insulation enabled the work to be carried out internally without the workers having to access the roof.’

Andrew continues: ‘The WALLTITE Polyurethane spray foam insulation system enabled us to save on the cost and time of the refurbishment process. A speedy and simple operation was a crucial factor for this project as the academic rooms needed to be completed in time for the return of staff and students following the summer break.’

The refurbishment project delivered academic staff offices, meeting rooms and research areas. The refurbishment has created a far more comfortable environment and greatly improved the energy efficiency of the space.
