Environmental
Polyfoam Linerboard is free from CFCs, HCFCs and any other
material with ozone depletion potential in its manufacture and
content and represents no known threat to the environment. The
extruded polystyrene in Polyfoam Linerboard is non
biodegradable.
Polyfoam Linerboard is 100% recyclable.
Compression resistance
The rigidity of the Polyfoam board behind the plasterboard will
offer an excellent support to the finished internal lining and
assist in the resistance of impact, helping to prolong its service
life.
Moisture resistance
Walls should be sound and weatherproof before applying a thermal
plasterboard laminate. Damp walls could have a detrimental effect
on adhesive performance.
When lining internal walls in refurbishment projects the
existing wall is often in a state of disrepair, which can mean
dampness. The Polyfoam insulation backing to the plasterboard is
resistant to moisture absorption and can offer the best piece of
mind solution for an application where potential moisture ingress
is a concern. If in any doubt about adhesive use mechanical
fixings.
Fire Performance
Polyfoam Linerboard consists of a 9.5mm plasterboard which
offers excellent fire performance as a facing material and Polyfoam
insulation which contains a flame retardant to inhibit localised
ignition.
When installed on dabs a secondary mechanical fixing in the top
corners of each board will ensure the integrity of the internal
finish during evacuation in case of fire.
Handling and storage
The boards are easy to handle and nonirritant, no special
protective clothing is required when installing them.
Polyfoam Linerboard is supplied on pallets, labelled with
identifying product and manufacturing data.
Ensure the boards are not stored close to open flame or other
ignition source, also avoid volatile compounds and chemicals such
as solvents.
Polyfoam products should not be left exposed to prolonged
sunlight as this will result in surface degradation. Where outside
storage for extended periods is required cover with opaque/light
coloured sheeting.
