25mm Celotex TB4000 PIR Insulation Board - TB4025

Celotex TB4025 is targeted at cut-to-fit applications between rafters or joists and enables users to achieve lower U-values with a single layer of insulation than has previously been possible. It is also appropriate for use in floors and walls. With low emissivity foil facings, TB4025 is manufactured from rigid polyisocyanurate (PIR) using a blend of blowing agents that have zero ozone depletion potential (zero ODP) and low global warming potential (GWP).

Note: Would also be known as TB3025 from January 2018.
