Also known as twin wall polycarbonate and twin wall polycarbonate sheets, twinwall polycarbonate is manufactured with two outer faces connected by internal ribs. This creates hollow channels through the sheet, combining useful rigidity with relatively low weight.

Our range includes different finishes and sizes for applications including suitable roofing, canopies, covered walkways, lean-to structures, greenhouse-style structures and other outdoor projects.

◇

Lightweight

Multiwall construction helps reduce overall panel weight while retaining useful rigidity.

✓

Impact Resistant

Polycarbonate provides high impact resistance compared with many conventional glazing materials.

°C

Thermal Performance

Internal air channels provide thermal insulation characteristics compared with solid sheet.

☼

Natural Light

Available finishes provide different levels and types of natural light transmission.

What Is Twinwall Polycarbonate?

Twinwall polycarbonate is a multiwall sheet material made from polycarbonate. It has two outer faces joined by internal ribs, creating hollow channels within the panel.

This construction provides a combination of low weight, rigidity and thermal insulation characteristics. It is widely used for applications where a lightweight translucent roofing or glazing material is required.

Twinwall polycarbonate roofing is commonly used for suitable canopies, lean-to roofs, covered walkways, greenhouse-style structures and other lightweight outdoor roofing applications. Always check the individual product specification before installation.

Choose Your Twinwall Polycarbonate

The colour of a twinwall polycarbonate sheet affects its appearance and light transmission. Select an option below to compare the main finishes.

Clear Opal Bronze

Clear Twinwall Polycarbonate

Clear twinwall polycarbonate has a transparent appearance and is selected where high natural light transmission is important.

It can be suitable for canopies, daylight roofing, greenhouse-style structures and other applications where maintaining visibility and natural light is a priority.

High natural light transmission

Transparent appearance

Suitable for daylight roofing

Lightweight multiwall construction

Opal Twinwall Polycarbonate

Opal twinwall polycarbonate has a translucent appearance and provides more diffused light than clear sheet.

It can be selected where softer light and a less transparent appearance are preferred.

Translucent appearance

Diffused natural light

Less transparent than clear

Suitable for selected roofing applications

Bronze Twinwall Polycarbonate

Bronze twinwall polycarbonate has a tinted appearance and provides lower light transmission than clear sheet.

It can be selected where a darker visual finish and reduced light transmission are preferred.

Tinted appearance

Suitable for selected roofing applications

Clear vs Opal vs Bronze Twinwall Polycarbonate

Finish	Appearance	Light Transmission	Typical Selection
Clear	Transparent	High natural light transmission	Maximum daylight and visibility
Opal	Translucent	More diffused light	Softer, diffused daylight
Bronze	Tinted	Lower light transmission	Darker appearance and reduced light

Twinwall Polycarbonate Roofing

Twinwall polycarbonate roofing provides a lightweight way of introducing natural daylight into suitable covered structures. The panels can be used for applications such as canopies, lean-to roofs, covered walkways and greenhouse-style structures.

The hollow internal structure provides useful thermal insulation characteristics while keeping the panels relatively lightweight. The performance of the completed roof depends on the sheet specification and installation system.

Check the required roof pitch

Check recommended support spacing

Allow for thermal movement

Use suitable fixings

Identify the UV-protected face

Follow channel sealing requirements

Applications for Twinwall Polycarbonate Sheets

Twinwall polycarbonate sheets can be used for a range of roofing, glazing and outdoor applications, subject to the specification and installation requirements of the individual product.

Canopies

Lightweight roofing for entrances, walkways and covered outdoor areas.

Greenhouses

Suitable for structures where natural light and thermal performance are required.

Lean-To Roofs

Lightweight roofing for compatible extensions, sheds and outdoor structures.

Covered Walkways

Provides weather protection while allowing natural daylight through the roof.

Rooflights

Can introduce natural light into suitable garages, garden buildings and other structures.

Screens & Partitions

Suitable for selected lightweight screening and partitioning applications.

Twinwall Polycarbonate Sheet Sizes

Choosing the correct twinwall polycarbonate sheet size can help reduce cutting, waste and the number of joints required. Consider the dimensions of the structure, support positions, sheet orientation and thermal movement when planning the installation.

Consideration	Why It Matters
Sheet length	Affects coverage and the number of horizontal joints.
Sheet width	Needs to work with the supporting structure and glazing system.
Sheet thickness	Affects stiffness and application suitability.
Colour	Affects appearance and light transmission.
Roof pitch	Must meet the requirements of the selected product.

Twinwall Polycarbonate Installation

Correct installation is important because polycarbonate expands and contracts with changes in temperature. The supporting structure, fixings and glazing system should therefore accommodate thermal movement.

Measure

Measure the structure carefully and plan the sheet layout before cutting.

Orientate

Identify the UV-protected face and ensure the channels run in the correct direction.

Fix

Use suitable fixings and allow for the manufacturer's specified thermal movement.

Finish

Complete channel sealing, end protection and profiles according to the product instructions.

Important: Installation requirements vary between polycarbonate systems. Always check the individual product technical information for roof pitch, support spacing, fixing details, UV protection and channel sealing.

Can Twinwall Polycarbonate Sheets Be Cut?

Yes. Twinwall polycarbonate sheets can generally be cut using suitable equipment. Straight cuts can commonly be made using an appropriate fine-toothed saw or other suitable sheet-cutting equipment.

Support the panel properly during cutting and take care not to crush or damage the internal ribs. Remove cutting debris from the channels and finish the sheet ends in accordance with the manufacturer's instructions.

Twinwall Polycarbonate vs Solid Polycarbonate

Feature	Twinwall Polycarbonate	Solid Polycarbonate
Construction	Two faces connected by internal ribs	Continuous solid sheet
Weight	Lightweight multiwall construction	Generally heavier at equivalent material thickness
Thermal performance	Internal air channels provide insulation characteristics	Depends on sheet thickness and specification
Appearance	Internal channels visible at the sheet edge	Solid continuous appearance
Common applications	Roofing, canopies, glazing and lightweight structures	Glazing, protection and fabrication
