Expanded PIR Foam
IBSL would like to introduce their expanded PIR foam, factory made, rigid pre-formed valve covers. The covers are moulded from expanded PIR foam which forms a dense, non absorbent outer skin encasing a fine grained cell matrix. Even when cut a 94% closed cell structure exists - resisting moisture penetration. The covers are easily fitted and secured with Velcro straps making access for inspection or service of the valve simple.
Although much stronger than most conventional materials with a density of 60kg/m3, the covers can be trimmed or modified with a sharp knife. To maintain the vapour seal, a bead of mastic must be applied to the mating surfaces.
The covers are coloured grey to match metallic insulation cladding but can be pigmented green to suit chilled water services. In external situations we recommend the cover is painted as additional protection from UV.
