Excellent UV protection

By its nature G.R.P glazing sheets allow a diffused, natural daylight to enter buildings. Solar glare and hot spots are eliminated to provide a more comfortable environment for the occupants of the building. A single sheet of 1.3mm will provide a light transmission of 80-85%.

Low maintenance

Using warm water and a mild detergent, the material can be cleansed to ensure the high levels of light transmission expected and to prevent any growth which may attack the protective surface or dirt accumulation which could lead to heat build up. Polyester translucent sheet does not absorb dust, dirt, oil or grease so dirt retention is kept low.

Service temperature

G.R.P sheets can withstand both high and low temperatures from -20˚C to +80˚C.

Excellent fire performance

Tested in accordance with BS476 in the UK, achieving the classifications required for building construction.
