What Is a Polycarbonate Hollow Sheet?
A polycarbonate hollow sheet is an extruded PC panel containing internal ribs or hollow channels between the outer surfaces. This structured design reduces weight compared with an equivalent solid panel while providing useful stiffness for supported roofing and glazing applications.
The hollow air spaces can also reduce heat transfer compared with a single solid layer, which is why structured polycarbonate is commonly used for daylighting, greenhouse glazing, skylights and lightweight roofing.
Hollow polycarbonate is also commonly described as multiwall polycarbonate, twinwall polycarbonate or structured PC sheet. The exact internal wall configuration should be confirmed for each product specification because wall design influences rigidity, weight and thermal performance.
Key Features of Polycarbonate Hollow Sheet
1. Lightweight Hollow Structure: Internal channels reduce panel weight, which can simplify handling, transportation and installation.
2. Natural Daylighting: Clear and selected translucent colors allow daylight to enter roofing, skylight and greenhouse structures.
3. Thermal Performance: Hollow air spaces can help reduce heat transfer compared with single-layer solid glazing. Exact thermal performance depends on wall structure, sheet thickness and panel weight.
4. Impact Performance: Polycarbonate is selected for applications requiring greater toughness than brittle glazing materials. Actual performance depends on panel thickness, rib structure, support spacing and installation.
5. Multiple Color Options: Clear, blue, green, opal, brown, grey and other customized colors can be evaluated for daylight, privacy and architectural appearance.
6. Custom Length: Sheet length can be discussed according to project dimensions, packing requirements and transportation conditions.
Polycarbonate Hollow Sheet Applications
Roofing: Hollow PC panels can be used in lightweight covered structures where daylight transmission and reduced roof-panel weight are required.
Skylights: Clear or translucent polycarbonate panels can introduce natural daylight into industrial, commercial and agricultural buildings.
Greenhouses: Hollow PC sheet can be evaluated for greenhouse walls and roofing where light transmission, panel weight and thermal performance are important.
Canopies: Lightweight structured sheets can be incorporated into entrance canopies, walkway covers and other supported weather-cover systems.
Partitions: Opal, tinted or clear sheets can be used in lightweight interior and semi-enclosed partitions where natural light or visual separation is required.
Architectural Daylighting: Hollow polycarbonate can be integrated into walls, rooflights and translucent building elements according to the project design.

UV Protection for Outdoor Construction
Polycarbonate used for outdoor construction should be selected with the appropriate UV-protection configuration. Prolonged sunlight exposure can degrade unprotected polycarbonate, so buyers should confirm whether the project requires one-side or two-side UV protection.
The UV-protected side must be installed according to the product marking and project instructions. Do not assume that every hollow polycarbonate sheet has the same UV configuration.
Installation Considerations
Allow for Thermal Expansion
Polycarbonate expands and contracts as temperature changes. Installation profiles, fixing holes and panel clearances should allow sufficient movement rather than clamping the sheet rigidly.
Install the Channels in the Correct Direction
For sloped roofing and vertical glazing, hollow channels are generally oriented in the direction that allows drainage and minimizes trapped condensation. Final orientation should follow the installation drawing.
Seal Open Channels Correctly
Appropriate end tapes and profiles can help reduce the entry of dust, insects and moisture while allowing drainage where required. The sealing system should match the panel orientation and project environment.
Use Polycarbonate-Compatible Sealants
Sealants, tapes, gaskets and cleaners should be chemically compatible with polycarbonate. Unverified chemicals can cause stress cracking or surface damage.
Technical Documentation
The existing product documentation includes a REACH report for PC sheet material. Buyers requiring REACH, RoHS, SGS, CE, fire-performance, UV, structural or other project documentation should confirm the exact document scope, version and applicability to the hollow polycarbonate grade being ordered.
