25mm Grey Athermic Polycarbonate Sheets

Our 25mm Grey Athermic Polycarbonate Sheets are a premium roofing solution designed to provide exceptional thermal performance, solar control and modern aesthetics. Featuring advanced athermic technology, these sheets help reduce heat build-up while still allowing natural daylight to enter the space below.

Ideal for conservatories, garden rooms, canopies and commercial roof glazing, grey athermic polycarbonate offers a stylish and energy-efficient alternative to standard roofing materials.

What is Athermic Polycarbonate?

Athermic polycarbonate is specifically designed to reduce solar heat gain by reflecting a greater proportion of the sun's energy compared with standard clear, bronze or opal sheets.

This helps create a cooler and more comfortable environment beneath the roof during warmer weather while still maintaining excellent natural light levels.

Benefits of 25mm Grey Athermic Polycarbonate

Five-Wall Construction

The 25mm five-wall structure contains multiple insulating chambers that provide outstanding thermal performance and increased rigidity.

This multiwall design helps improve energy efficiency while delivering excellent structural strength for larger roofing applications.

Superior Solar Control

Grey athermic polycarbonate is particularly effective on south-facing roofs and areas exposed to prolonged sunlight. By helping to reduce heat transmission, it can make conservatories, garden rooms and covered outdoor spaces significantly more comfortable during summer months.

The grey tint also provides a contemporary appearance that complements modern architecture and outdoor living spaces.
