01What Is Corrugated Polycarbonate?
Corrugated polycarbonate is a polycarbonate sheet formed into a ribbed profile for daylighting roofs and walls. Its single-layer surface follows the rib crests and troughs; this differs from multiwall polycarbonate with internal air chambers.
- 1Profile: square or rounded ribs, depending on the range; check compatibility when combining with an existing roof.
- 2Light: colour and thickness affect how light passes through; choose according to the space's needs.
- 3Installation System: sheets, framing, screws and accessories must be compatible to complete the roof.

Profiles for Roofing Systems
Check the pitch, rib height and shape when combining with existing metal or other roofing sheets.
UV Protection by Range
Check the sheet's UV-protected side and technical documentation. Install the indicated side in the correct orientation.
Flexible Specifications
Select the profile range, thickness, colour and length according to the project plan and supply availability.
DETAILS THAT ENSURE COMPATIBILITY
Even with the Same Rib Count, Check the Cross-Section.
Rib crests, troughs, pitch and height determine compatibility with metal roofing. Before ordering replacement daylighting sheets, send a cross-section photo or roof sample to check compatibility.

LIGHT & APPEARANCE
04Colours for Every Space
Coordinate sheet colour with the frame, façade and landscape. Select a physical sample before finalising the order.
ClearKeeps a bright feel and a clear view of the sky
Opal WhiteSuggests softer light and neutral tones
Bronze / Brown BronzeWarm tones for awnings and gardens
BlueDistinctive, modern blue tones
GreenCoordinates with green spaces
Lake Blue / TurquoiseSoft blue tones for daylighting roofs
Colour names and options vary by sheet range. Use the product filters to view the listed colours; confirm the colour–thickness–size combination when quoting.
Light Transmission
For an exact percentage, request the data sheet for the correct colour, thickness and sheet model. Sample images illustrate colour and do not replace optical specifications.
UV & Solar Heat
The UV layer protects the sheet from ultraviolet radiation. Heat reduction must be assessed separately through solar-energy-control data and ventilation design.

SUGGESTED APPLICATIONS
05Bring Daylight into Your Project
Select materials according to intended use while checking the framing and installation conditions.
Awnings & Carports
Roof courtyards, walkways and parking areas. Consider sun direction, sheet colour, ventilation and drainage.
Factory Daylighting Strips
Add natural daylight to factories and warehouses. Check metal-roof profiles, purlin spacing, wind loads and project requirements.
Greenhouses & Growing Areas
Select light levels for the crop and operating conditions, combined with ventilation. If anti-drip performance is needed, confirm that the selected sheet range provides it.

DETAILS THAT DETERMINE DURABILITY
06Match the Profile. Install the Correct System.
Principles only. Slope, purlin spacing, expansion gaps and fixings must follow the documentation for the exact sheets and accessory system.
Match the Profile Before Installation
Send a cross-section photo or metal-roof sample to compare rib pitch, height, crests and troughs. The same rib count can still have different profiles.
Orient the UV-Protected Side Correctly
Read the film markings or identification strip. Face the UV side towards the sun according to the sheet documentation; check two-sided protection ranges separately.
Overlap According to the Roofing System
Run ribs along the roof slope. Side overlaps, end overlaps and overlap direction must suit the slope, sheet length and wind and rain conditions.
Allow for Thermal Expansion
Drilled holes and installation gaps must allow thermal movement. Avoid overtightening, which can flatten ribs or create stress around screws.
Select Compatible Fixings & Accessories
Screws, washers, rib supports, gaskets, flashings and sealants must suit the polycarbonate sheets and frame type. Follow each product's installation system for screw positions.
Check the Roof at Handover
Check overlaps, fixings, drainage and protective film. Do not walk directly on daylighting sheets; use a structurally supported work platform.

Cleaning & Storage
Use water and a soft cloth, with a cleaner compatible with polycarbonate; avoid abrasive materials and unsuitable chemicals. Store sheets on a flat, clean surface in a dry, ventilated place away from direct sunlight. View Reference Guide ↗

ADVICE BEFORE YOU BUY
08Frequently Asked Questions
How Does Corrugated Polycarbonate Differ from Solid and Multiwall Sheets?
Corrugated polycarbonate has rounded or square ribs. Flat solid polycarbonate is a single solid sheet with a flat surface; multiwall polycarbonate has internal walls and air chambers. Select the structure according to the roofing system, daylighting requirements and fixing method.
Should I Choose 5, 6, 7, 9 or 11 Ribs?
Start with the roof profile. For roofs combined with metal sheets, compare pitch, height, rib shape and effective width. Rib count identifies the sheet range; it is not a durability rating. Send a metal-roof cross-section photo so LIONVINA can help compare compatibility.
Which Thickness Should I Choose for My Roof?
Roof dimensions, purlin spacing, project location and loading conditions are needed. Then consult the technical table for the exact sheet range. Thickness or rib count alone is not enough to determine support spacing.
What Is the Difference Between Overall and Effective Width?
Overall width is the physical sheet width. Effective width is the roof coverage after deducting the installation overlap. Use the confirmed effective width when calculating sheets side by side. For example, a roof 5 m across with an effective width of 1 m requires 5 sheets across, before edge layout and waste are considered.
Will Clear or UV-Protected Sheets Keep the Roof Cool?
Daylighting sheets can still admit solar energy into a space. UV protection and heat reduction are separate properties. Consider light transmission, solar-control data, sun direction, ventilation and the roofing system.
Can Corrugated Polycarbonate Be Bent into a Vaulted Roof?
Some ranges can be curved within permitted limits. The minimum radius depends on profile and thickness; check the exact range's documentation before installation. Do not force a curve based only on illustrative images.
How Are Prices, Available Colours and Warranty Terms Confirmed?
Quotations depend on profile range, thickness, colour, width, length, quantity, accessories and delivery location. Availability, warranty period and terms are confirmed for the product code in the quotation.
What Should I Send for Prompt Advice?
Send roof and metal-profile cross-section photos, roof dimensions, purlin spacing, desired colour or thickness, quantity and delivery province/city. Attach drawings to the quotation form if available.
