ThermalShield is Mercia Industrial's premium insulated partitioning system, designed for facilities that need to maintain distinct temperature zones within a single building. From refrigerated storage areas that must be kept below 4 °C to warm production cells that must stay above 18 °C, ThermalShield creates thermally broken enclosures that slash energy costs and improve working conditions simultaneously. The system uses twin-skin insulated PVC panels with a closed-cell foam core, delivering U-values as low as 0.4 W/m²K depending on panel thickness and configuration.
The ThermalShield range integrates seamlessly with Mercia's complementary door systems, including strip curtains, fast-acting roller doors, and insulated swing doors, allowing personnel and forklift traffic to pass between temperature zones without compromising thermal integrity. Every door integration is factory-engineered to minimise air exchange, which reduces both energy waste and the condensation that can create hazardous floor surfaces or damage stored goods.
Facility operators typically achieve payback on ThermalShield within 18 to 36 months through reduced heating and refrigeration running costs. The system is especially popular in cold storage logistics, food and beverage manufacturing, pharmaceutical warehousing, and any application where HVAC costs are a major line item. Panels are available in a range of thicknesses to meet any insulation specification, and the system carries third-party thermal certification for use in buildings subject to BREEAM assessment.
