Optimum performance is a basic yet fundamental priority in controlled environments. Since controlling the precise temperature of a room can be up to 10 times more expensive than heat energy, it is necessary to use the most energy efficient insulation possible to reduce energy costs. PIR (Polyisocyanurate) insulation offers the best thermal performance of any coldstore insulating material on the market.

The insulated panels used in Kingspan’s UltraBox walk-in coldrooms have an ECOsafe, environmentally sustainable PIR insulation core which has a low Global Warming Potential (GWP).  These panels are also non-deleterious and highly resistant to moisture ingress, chemicals, solvents, mould and bacterial growth.

We offer two UltraBox systems:

  • Continuous - panels are supplied with rebated corners.
  • Camlock - panels are manufactured with camlocks for easy assembly.

These modular units can be custom-built to your requirements or bought "off the shelf" in a range of sizes. Delivered as flat pack walk in coldrooms, these units combine very high levels of guaranteed performance with ease of assembly and a fully supported fast track service.
