GRC is one of the most popular materials used for creative prefabricated architectural cladding. GRC’s ability to be molded into thin, lightweight panels with a wide variety of shapes, forms and surface finishes has been appreciated by a growing audience of architects and engineers worldwide.
- GRC is easily molded to reproduce shapes, details, and textures
- GRC’s high strength allows design of thin, lightweight cladding elements
- GRC can be colored with pigments, paints and natural stone facings
- GRC cladding can replace non-structural precast concrete where weight and/or shape may be problematic
GRC cladding panels are generally manufactured by the “Hand Spray” technique. As the name implies, the material is sprayed into a mold using special machinery. The method can produce high performance materials from which panels with extremely thin, lightweight sections are achievable.
GRC is an ideal material for use on a wide variety of roofing structures. It is lightweight but tough, easy to fix and unaffected by environmental conditions even urban pollution. It can imitate traditional roofing materials such as slate, natural stone or clay products but unlike these materials it is neither heavy nor brittle. It can be molded into complex shapes for accessories including chimney sleeves or caps or for resolving difficult problems on non-standard roofs. It is non-combustible with high impact strength and is used on either flat or pitched roofs.
On pitched roofs it can imitate natural slate in both appearance and texture but can be fixed without pre-boring using conventional slate nails and its tough nature virtually eliminates breakage during fixing.
Flat roofs can be made more attractive by using promenade tiles which can be made non-slip and in a variety of natural earth pigments or colored sands.
Corrugated GRC roofing sheets, which are entirely free of asbestos, exhibit a high ductile, non-brittle behavior under test.
This is an introduction to the exciting world of Glassfiber Reinforced Gypsum (GRG) also referred to as Fiberglass Reinforced Gypsum (FRG). Since its introduction, GRG has become extremely popular among the interior design industry.
RGR holds superior for retardant properties.
GRG offers a variety of shapes (similar to what plaster and precast offer).
GRG is lightweight.
Composition – GRG is composed of:
Gypsum – a hard mineral
Glass Fibers – to provide tensile and flexural strength
Polymers – to improve toughness
Molding, ceiling, columns, light covers are all good candidates for GRG.
