Why GFRG is best

Most innovative method created by IIT Madras students, who have built low-cost, eco-friendly houses by using ‘Glass Fibre Reinforced Gypsum’ (GFRG) panels.

Economy

Readily available and easy to apply

Gypsum board is readily available and easy to apply. It is an inexpensive wall surfacing material that provides a fire resistant interior finish. Gypsum board building systems can generally be installed at significantly lower labor costs than most alternate systems. Ceilings, floor and staircase made using this don't require plastering.

Durability

Excellent dimensional stability and durability

Gypsum board is used to construct strong, high quality walls and ceilings that offer excellent dimensional stability and durability. Surfaces created using gypsum board are easily decorated and refinished.

Eco-friendly

It can be used for recycling.

GRG as a GEP (Green Environmental Protection) material has no odor, and its Radioactive Nuclide Limit is accord with A-style decoration material standard of GB6566-2001, which can be used for recycling.

Easy Manufacture

Less manufacture period

Mold-release time of GRG products needs only 30 minutes, and drying time only 4 hours, which can largely decrease the manufacture period.

Crack and shrink resistant

no chap and no distortion after long life use

GRG has no corrosive action on glass fiber, and its wet-dry shrinkage ratio is less than 0.01%, which ensures the stability and durability of the product and appears no chap and no distortion after long life use.

Superior strength

Exceed 10 times of the rupture load

Superior strength and durability: after experiment, the rupture load of GRG product is more than 1200N, which exceed 10 times of the rupture load of JC/T799-1998(1996)Decoration Gypsum (118N).

Breathing Effect

microclimate living condition

GRG board is a special material consisting of mini-hole structure. In nature environment, multi-hole can absorb or release moistures. When it’s high temperature and low humidity indoor, the board will gradually release moistures from mini-hole; when it’s low temperature and high humidity, it will absorb moistures from the air. Such RELEASE and ABSORB forms the “Breathing” effect. This kind of circulation appears the effect of indoor humidity adjustment, creating a comfortable “microclimate” of working and living conditions.

Fireproof

Release 15%~20% moistures of its own weight

GRG material is an A-Class fireproof material. When meets fire, it can not only prevent burning, but also release 15%~20% moistures of its own weight, which can largely reduce the surface temperature and fire damage.

Soundproof

sound insulation and absorption

after test, the permeation lost of 4mm thick GRG material is 500Hz 23d, 100Hz 27db, and its air-dry specific gravity is 1.75, which accord with echo requirement of special acoustics. Though style design, it can form a well absorbing structure for sound insulation and absorption.

Easy Installationl

It’s easy for processing on site

GRG can be made in different styles based on designers, and can be produced and divided in large chunk. It’s easy for processing on site, quick and flexible for installation, and can be seamlessly spliced in large piece to form an integrated style without errors, especially for opening, camber and corner, etc.

Smooth & Flawless of Surface

excellent decoration effect

whiteness surpasses more than 85%, and it can be well plastered with all kinds of paints and decoration materials to form an excellent effect.

Light weight

decrease the main body weight and component load

Standard thickness of the plane part of GRG product is 3.2~8.8mm (more thick if required), and the weight of per square meter is only 4.9~9.8kg, which can decrease the main body weight and component load.
