4MM - Twinwall

Our 4mm Twinwall Polycarbonate Sheeting is the perfect light-weight application for replacing broken glazing. 10 times stronger than actual glass, without ageing, it’s great for replacing greenhouse glass, shed windows or anywhere that a low-cost application is required. 
The Twinwall finish distorts the light, whilst allowing up to 85% of the light come through. It’s available in a variety of widths and lengths, and oversized length sheeting is available upon request.
