The challenge
A public leisure centre pool runs hard. High bather numbers and long opening hours keep the hall warm and saturated with moisture, and that humid air constantly seeks out cooler surfaces in the roof and walls where it condenses. For a council or operator running the facility, that means a real risk of long-term fabric damage and rising energy costs.
At Newport Leisure Centre in Telford, the building had to keep serving the public throughout, so the insulation system needed to address the roof structure thoroughly and durably. Gaps, seams or cold bridges in the insulation would allow moist air to reach the cold deck and undermine the whole effort.
The ThermoFoam solution
ThermoFoam applied Enverge closed-cell spray foam directly to the pool hall structure. Curing in place, the foam self-bonds to the substrate and forms a single continuous layer across the roof and its members — no boards, no mechanical fixings and no joints where warm, humid air could slip through to the cold surface behind.
The closed-cell foam is dense and resists moisture migration, so it raises the thermal performance of the envelope while helping keep humid air off the cooler surfaces that drive condensation. The system is supplied by Duratite, UK distributor of record, and certified — a documented specification for a public-sector facility.
The result
The pool hall now has a more thermally stable, better-protected envelope able to cope with the demands of a busy public pool. The seamless, bonded application reduces the condensation risk to the structure and is backed by a 25-year manufacturer-backed product warranty.
