New roof is a breath of fresh air

A Mitsubishi Air Conditioning manufacturing facility in Livingston has been reroofed without any disruption to production.

The retrofit contract was carried out by Mitie Tilley Roofing using the Icopal Thermosolo system.

In total, just over 9,000 square metres of roofing membranes were installed across the factory’s main roof area during the seven-week project, which took place last summer.

Gavin Gowland of Mitie Tilley said, “As a commercial and industrial roofing specialist we make frequent use of the Icopal range and have a good working relationship with the manufacturer.

“In the case of the Mitsubishi Air Conditioning project last year we were on site for some seven weeks and had good cooperation from both Icopal and the client regarding deliveries and logistics generally.

“While the roof was not in a particularly poor condition, the production processes carried on within the plant simply cannot be put at risk so the integrity of the waterproofing system is critical.

“We therefore began the reroofing using a 15mm layer of recovery board, followed by two layers of the Icopal felt for all the upstand and other details. Then a single layer across the rest of the roof.”

Jim McDairmid, the maintenance technician for Mitsubishi Air Conditioning added, “The choice of the Icopal system by Mitie meant we were getting an integrated product solution from a single source backed by a 20-year guarantee. I liaised with Mitie’s contracts manager and the technical manager for Icopal throughout the lead up to the work and during installation, with everything proceeding smoothly.

“Mechanically fixing the boards through the existing waterproofing system saved time as well as money and actually offered us additional insulation prior to the Icopal membranes being fully bonded down and details such as the skylights being dealt with. The installation has gone well and the finished job looks good.”
