About Us

Greenhill Systems are distributors of polycarbonate sheeting and specialist plastic products to the agricultural and construction sectors.

We can provide the latest products to increase animal welfare, health and productivity whilst creating an optimum working environment with the added benefit of energy savings.

Marlon Heatguard is an innovative development in polycarbonate sheet which limits heat build up through the sheet whilst transmitting natural light. It is ideal in any situation where natural light is required.

What Is HeatGuard?

Heatguard utilises a specially developed pigment to significantly reduce heat gain in the building. Under the sun, heatguard acts like a mirror to reflect heat, thus minimising solar heat gain and hot spots, lowers the need for artificial lighting, lowering the running costs of the building for years to come.
