Technical Information

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.

  • U-values ranging from 0.08W/m2K to 0.38W/m2K - fully compliant with the appropriate National Building Regulations.
  • Available in lengths up to 19.7m.
  • Available in thicknesses from 50mm to 220mm.
