Polycarbonate roof panels are lightweight, impact-resistant glazing sheets used for covered outdoor spaces, greenhouses, carports (see custom carport roof sheets), pergolas, skylights, and industrial roofing. They are available in three main grades: solid, multiwall, and corrugated.
Compared to glass, polycarbonate panels are about half the weight and 250 times more impact-resistant while offering similar light transmission. Compared to PVC panels, polycarbonate withstands a wider temperature range and provides better UV protection.
Half the weight of glass — easier transport and faster installation
250x stronger than glass — withstands hail, wind, and debris
Co-extruded UV protection — blocks harmful UV while transmitting daylight
Available in clear, opal, bronze, and custom colors
Why Choose Polycarbonate Roof Panels
Impact Resistant
250 times stronger than glass. Withstands hail, falling branches, and wind-driven debris without shattering.
Lightweight
About half the weight of glass. Reduces structural load, speeds up transport, and simplifies on-site handling.
UV Protected
Co-extruded UV layer blocks harmful radiation while allowing daylight transmission. Prevents yellowing and embrittlement.
Thermal Insulation
Multiwall panels create air channels that reduce heat transfer. Keeps interiors cooler in summer and warmer in winter.
Easy to Install
Can be cut, drilled, and fastened with standard tools. No special equipment required for cutting or handling on site.
Polycarbonate Roof Panel Types
Solid Sheets
Thickness 2 mm to 15 mm. Clear or tinted. Best when glass-like clarity, flat spans, and high light transmission are required. Suitable for pergolas, carports, canopies, and skylights.
Multiwall Panels
Twin-wall and triple-wall structures from 4 mm to 25 mm. Superior thermal insulation, excellent stiffness-to-weight ratio, and built-in UV protection. Ideal for greenhouses, covered walkways, and industrial roofing.
Corrugated Sheets
Wave profile for quick overlap installation. Lightweight, impact-resistant, and available in clear or opal. Common for carports, canopies, lean-to roofs, and agricultural shelters.

How to Install Polycarbonate Roof Panels
A quick overview of the three main stages for a professional polycarbonate roof installation.
Measure & Cut
Measure roof area and cut panels to length with a fine-tooth circular saw or jigsaw. Keep protective film on during cutting and remove chips from channels on multiwall panels.
Frame & Seal
Install support framing according to span tables and local wind and snow loads. Apply compatible glazing tapes, sealants, and edge closures before placing panels.
Fasten & Finish
Pre-drill oversized holes, use approved washers and caps, and avoid overtightening. Close edges with profiles or flashing for weather protection.
Polycarbonate Roof Panels FAQ
What thickness polycarbonate roof panel do I need?
Span, load, and local building codes determine thickness. Multiwall panels from 6-10mm are common. Larger spans, snow loads, and commercial projects need thicker panels confirmed by span tables.
Should I use solid or multiwall polycarbonate?
Choose solid polycarbonate when clarity and glass-like appearance are the priority. Choose multiwall panels when insulation, stiffness, lower weight, and diffuse daylight matter more.
How do contractors cut polycarbonate panels?
Panels can be cut with a fine-tooth circular saw, table saw, or jigsaw. Support the sheet, keep the protective film on during cutting, and remove chips from channels before sealing.
How long does UV protection last?
Service life depends on climate, thickness, color, installation angle, and UV layer configuration. Bakway can quote UV-protected panels according to your outdoor exposure and warranty requirements.
What is the minimum order quantity?
MOQ depends on sheet type, color, thickness, profile, and packing. Standard clear products usually support lower MOQs than custom colors or special profiles.
Can Bakway produce custom sizes?
Yes. Custom lengths, colors, thicknesses, UV configurations, and packing plans can be produced for B2B roofing, greenhouse, canopy, and distributor orders.

Polycarbonate Roof Panels vs Polycarbonate Roofing Sheets
"Roof panels" and "roofing sheets" describe the same polycarbonate roofing products from different buyer angles: roof panels emphasise the rigid, ready-to-install format, while roofing sheets emphasise the raw material by profile and thickness. Bakway supplies both — in clear, bronze and opal — as solid, multiwall and corrugated polycarbonate for patios, pergolas, carports, skylights and industrial roofs.
More questions about polycarbonate roof panels
Q: Are clear polycarbonate roof panels available? A: Yes — clear roof panels give up to 90% light transmission with UV protection on the weather side, in corrugated, multiwall and solid profiles cut to your length.
Q: What is the difference between corrugated and multiwall polycarbonate roof panels? A: Corrugated panels are single-skin, low-cost and match standard metal roofing profiles; multiwall panels have hollow ribs for far better insulation, used on greenhouses, patios and cold roofs.
Clear & Transparent Roof Panels
Clear roof panels are the most requested option for patios, pergolas, carports and walkway covers where daylight matters. Polycarbonate delivers glass-like clarity with roughly 200× the impact strength of glass, so clear panels stay intact under hail, foot traffic during install and thermal cycling. Below are the clear and transparent formats Bakway supplies to distributors and contractors.
Clear corrugated roofing
0.8–1.5 mm wave and trapezoid profiles at ~88% light transmission — the go-to clear plastic roof panel for carports, sheds and agricultural covers. Matches common metal-roof profiles for mixed roofs.
Clear solid roof panels
2–10 mm flat clear sheet at up to 90% transmission for pergolas, canopies and skylights where a smooth, fully transparent roof is wanted. UV side co-extruded for outdoor use.
Clear multiwall roof panels
6–25 mm twin/triple-wall clear panels that keep daylight while adding insulation — used for conservatory roofs, commercial daylighting and greenhouse roofs.
Do clear polycarbonate roof panels yellow over time?
Not within the warranty period when the co-extruded UV layer faces the sun. Bakway clear panels carry a 10-year warranty against yellowing and UV breakage; installing the UV side down is the most common cause of premature hazing.
How much light do clear roof panels let through?
Solid clear panels reach ~90%, clear corrugated ~88%, and clear multiwall 60–80% depending on wall structure. Opal and tinted grades are available where glare or heat control matters.
Are clear polycarbonate panels better than clear PVC or acrylic?
For roofing, yes: polycarbonate keeps clarity far longer than PVC and resists impact where acrylic cracks. It is the standard choice for clear roof panels that must survive hail and handling.
What sizes do clear roof panels come in?
Corrugated follows fixed profile widths; solid and multiwall run from 2,100 mm master width cut to length, with 4×8 ft as a standard cut. Send your rafter spacing and roof size for a panel recommendation.
