GRP doors are supplied as complete systems consisting of doors pre-hung in frames fitted with weathersealing components to ensure maximum effectiveness with minimum site labour. GRP Door Specifications

DOOR CONSTRUCTION
GRP doors are constructed using two GRP woodgrain skins permanently bonded to a perimeter sub-frame of synthetic material and filled with an insulating polyurethane core. The rigid polyurethane foam core is CFC and HCFC free, has an ozone depletion potential (ODP) of zero and a global warming potential (GWP) of less than five. GRP doors can be cut in width and cut-down in height, allowing the doors to be sized to fit existing openings for refurbishment projects. The slab construction provides a fully sealed product impervious to moisture.

THERMAL PERFORMANCE
GRP doors have a U value through the door of 0.6W/m2K, equivalent to approximately four solid timber doors.

U values of doorsets for use in building regulation calculations are available from our Technical Department.
