See Koolshield™ in action
How our insulated curtains keep the cold in — and why they out-perform PVC strips.
Why Koolshield™
The state of the art in thermal barrier technology
A true thermal barrier
Traditional PVC strip curtains constantly exchange air — and heat — every time they settle. Our patented Koolshield™ insulated curtains trap an insulating layer, working like double glazing for your doorway, so cold stays in and warm air stays out.
No drips, no floor ice
PVC strips are prone to condensation that drips and freezes into dangerous pools on chiller and freezer floors. Koolshield™ eliminates the condensation problem at source, keeping your walkways safe for staff and vehicles.
Hygienic by design
The unique anti-bacterial header and easy-clean panels make Koolshield™ ideal for food storage, processing and packaging installations — dairies, cold rooms and production areas where hygiene is critical.
Testing & savings
Field-tested in the most demanding conditions
Koolshield™ curtains have been field tested with high-tech thermal imaging on large-scale walk-in freezer installations — holding a −21°C freezer against outside temperatures of +10°C — and are guaranteed to perform from −25°C to +70°C.
Reduced load doesn't just cut your electricity bill: it also cuts wear on your evaporator systems, so your refrigeration plant runs at optimum settings for longer.
