Polycarbonate roof panels are lightweight, impact-resistant glazing sheets used for covered outdoor spaces, greenhouses, carports, 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.
