Corotherm Multiwall Polycarbonate Roofing Sheets provide a lightweight, durable and thermally efficient roofing solution for a wide range of domestic and commercial glazing projects. Manufactured from high-quality impact-resistant polycarbonate, these sheets offer excellent strength, insulation and long-lasting performance whilst allowing natural daylight to enter your outdoor space.

Suitable for conservatories, carports, lean-to roofs, canopies, verandas, greenhouses and covered seating areas, Corotherm sheets are available in a choice of thicknesses, widths and glazing tints to suit your individual project requirements.

Choose from 10mm Twinwall, 16mm Triplewall or 25mm 7-Wall sheet constructions, available in either 3m or 4m lengths and 700mm or 1050mm widths. Select Clear for maximum light transmission, Bronze for solar control or Opal for a softer diffused finish with additional privacy.

Each sheet incorporates a co-extruded UV protective layer to help prevent yellowing and discolouration over time and is backed by a 10-year manufacturer's guarantee for additional peace of mind.
