The challenge
Converting a warehouse-style building into an events and hospitality venue brings a comfort challenge: the original industrial shell offers little thermal resistance, so an expansive space like Depot in Cardiff is hard to keep warm for guests and loses heat readily across a very large roof and envelope.
Bare profiled warehouse roofs are also prone to condensation, where warm air from a busy event meets the cold roof underside and moisture forms above the crowd below. The venue needed an insulation solution that could be applied across a large roof, follow the profiled sheeting and steelwork continuously, and improve both warmth and moisture control.
The ThermoFoam solution
ThermoFoam applied Enverge closed-cell spray foam to the underside of the venue's warehouse roof. The closed-cell foam self-bonds to the sheeting as it cures, forming a continuous, seamless insulating layer that follows the profiled roof and steelwork across the full span without joints or fixings for heat and moisture to bypass.
Insulating and air-sealing in one application, the foam warms the internal roof surface so the cold underside that drives condensation is removed, while adding real thermal performance to a previously bare shell. ThermoFoam worked to the manufacturer's specification, controlling foam thickness across the large roof for a consistent result.
The result
Depot's Cardiff venue became a warmer, better-controlled space with the condensation risk of a bare warehouse roof addressed, improving comfort for events and guests across the large floor. The Enverge installation is backed by a 25-year manufacturer-backed product warranty, giving the operator long-term value.
