GRP Roofing

GRP Roofing

GRP stands for Glass Reinforced Plastics and is being hailed as the new generation of flat roofing. The roof is essentially a specially developed resin system which accommodates every day regular contraction and expansion.

A properly laid fibreglass roof should last for at least 25 years with no measurable deterioration.

A GRP flat roof consists of the following components:

  • A new 18mm OSB3 (Object Stranded Board) tongue and groove plywood roof deck
  • Edge trims and up-stands for roof lights (and ventilation – see cold roof later)
  • A thick fiberglass fleece (450g/m2 or 600g/m2) impregnated with epoxy resin
  • Solar reflective top coat

 

To install a GRP roof to the highest standard, strict guidelines must be followed and the highest quality resin or topcoat must be used. A GRP roof is not as flexible as felt/EPDM nor does it breathe as well so it is imperative that meticulous planning goes into the installation of a GRP flat roof.

GRP flat roofing systems have many benefits, including:

  • Durability
  • Low Maintenance
  • Long Guarantees
  • Flexible Usage
  • Simple no-flame installation
