Polycarbonate Roofing Sheets & Accessories – Supplied Across the UK

Welcome to polycarbonatex.co.uk, a UK-based retailer supplying multiwall polycarbonate roofing sheets and accessories for both DIY users and trade professionals.

We provide a range of lightweight, versatile polycarbonate roofing products suitable for pergolas, conservatories, garden rooms, carports, canopies, lean-to roofs, and covered walkways. Our focus is on supplying clear product information, compatible components, and options suited to different project requirements.

Multiwall Polycarbonate Roofing Systems

Multiwall polycarbonate is commonly used as an alternative to glass in a variety of domestic and light-commercial structures. It is designed with multiple internal chambers, which contribute to rigidity and thermal properties.

Typical characteristics of multiwall polycarbonate include:

  • Good impact resistance
  • Available light-transmission and solar-control options
  • Chambered structure for improved thermal performance
  • Lightweight construction

This makes it a practical material choice for a range of roofing and glazing applications.

Supplying Polycarbonate Roofing in the UK

polycarbonatex.co.uk supplies polycarbonate sheets and components sourced from recognised manufacturers and established brands.

We do not manufacture sheets ourselves; we operate as a retailer supplying products selected for suitability in UK outdoor structures and compatibility with common roofing systems.

Polycarbonate Sheets for Different Applications

Our multiwall polycarbonate sheets are available in several thicknesses and finishes to suit various installation types.

Typical Thickness Options

  • 4mm & 6mm – Often used for cold frames, greenhouses, and lightweight coverings
  • 10mm – Common for pergolas, carports, and walkways
  • 16mm – Suitable for garden rooms and conservatory-style roofs
  • 25mm – Thicker option used in higher-insulation applications

Available Sheet Finishes

  • Clear – High light transmission
  • Opal – Diffused light with reduced brightness
  • Bronze & Bronze Opal – Tinted options for lower light levels
  • Heat-reflective finishes – Designed to reduce the amount of heat absorbed by the sheet

These finishes allow you to select a sheet based on how much light or shading is preferred in your structure.

Polycarbonate Roofing Accessories

To support correct installation, we supply a full range of compatible accessories designed for use with multiwall polycarbonate roofing systems, including:

  • Glazing bars
  • Side and wall flashings
  • Sheet end closures
  • Breather and aluminium tapes
  • Fixing buttons

These components are intended to support:

  • Correct thermal expansion
  • Secure sheet placement
  • A finished appearance at joints and edges

Accessories and sheets supplied together help improve compatibility across the system.

Suitable for DIY & Trade Projects

Polycarbonate roofing materials are relatively lightweight and can be installed using standard tools, making them suitable for capable DIY users as well as trade installers.

Common uses include pergolas, patio covers, lean-to roofs, canopies, carports, conservatories, and walkway shelters.

Product listings include specifications and compatibility notes to help with planning and installation choices.

Material Characteristics

Multiwall polycarbonate is commonly chosen for:

  • Lightweight handling
  • Chambered structure for insulation
  • Versatile sheet thicknesses
  • Range of light-control finishes

These characteristics make it suitable for many outdoor roofing applications.

Care & Maintenance

Polycarbonate sheets typically require minimal routine care. Basic maintenance includes:

  • Occasional cleaning with mild detergent

Routine care helps support the expected lifespan of the roofing system.
