What is Multiwall Polycarbonate Sheet?
Multiwall Polycarbonate Sheet is a lightweight yet highly impact-resistant thermoplastic panel composed of multiple layers separated by air channels.
These hollow structures provide excellent thermal insulation, rigidity, and light transmission.
HSQY PLASTIC supplies high-quality Multiwall Polycarbonate Sheets for industrial roofing, skylights, greenhouses, and architectural glazing projects worldwide.
What are the key advantages of Multiwall Polycarbonate Sheet?
Multiwall Polycarbonate Sheet offers a unique combination of transparency, strength, and insulation.
It provides up to 200 times the impact resistance of glass at only half the weight.
The hollow structure improves energy efficiency by reducing heat transfer.
HSQY PLASTIC sheets also feature UV-protected surfaces for superior weather resistance and long lifespan.
What are the common applications of Multiwall Polycarbonate Sheet?
These sheets are widely used in industrial roofing, daylight domes, covered walkways, pergolas, and carports.
They are also ideal for agricultural greenhouses, sports facilities, sound barriers, and interior partitions.
Architects and contractors choose Multiwall PC Sheets for their balance of clarity, insulation, and durability.
What types or structures of Multiwall Polycarbonate Sheet are available?
HSQY PLASTIC offers a wide range of structures including twin-wall, triple-wall, four-wall, and X-structure sheets.
Each type offers different insulation and strength properties suitable for various applications.
Special anti-condensation, UV double-sided, and solar-control grades are also available on request.
What are the available thicknesses and sizes?
Common thicknesses include 4 mm, 6 mm, 8 mm, 10 mm, 12 mm, 16 mm, 20 mm, and 25 mm.
Standard width is 2100 mm, and length can be customized up to 11.8 m per sheet.
Custom cutting, color options, and special packaging are provided according to project requirements.
What colors and light transmittance options are available?
HSQY PLASTIC offers clear, opal (milky white), bronze, blue, green, and customized colors.
Light transmission ranges from 30 % to 82 % depending on color and thickness.
Sheets can also be treated with IR or UV filters for specific energy-saving or shading purposes.
Is Multiwall Polycarbonate Sheet UV-resistant and weatherproof?
Yes. All HSQY PLASTIC Multiwall Polycarbonate Sheets are co-extruded with a high-quality UV-protective layer.
This prevents yellowing, surface degradation, and brittleness caused by prolonged UV exposure.
The product performs reliably under extreme outdoor conditions, maintaining optical clarity and structural strength for over 10 years.
Is Multiwall Polycarbonate Sheet fire-resistant and safe to use?
Polycarbonate is a flame-retardant material that meets international safety standards such as UL-94 V-2 and EN 13501.
In the event of fire, it self-extinguishes and does not generate large amounts of toxic fumes.
The sheets are safe for use in public buildings, factories, and residential environments.
How should Multiwall Polycarbonate Sheets be installed?
Sheets should be installed with the UV-protected side facing outward.
Allow for thermal expansion (about 3 mm per meter) and use proper aluminum or polycarbonate profiles for joining.
Seal open ends with vented or anti-dust tape to prevent condensation and dust entry.
HSQY PLASTIC provides full installation guidelines and accessories upon request.
Are Multiwall Polycarbonate Sheets environmentally friendly?
Yes. Polycarbonate is 100 % recyclable and free from harmful substances such as lead or cadmium.
HSQY PLASTIC adopts eco-friendly production methods and uses clean energy where possible.
Due to its long lifespan and excellent insulation, it also helps reduce overall energy consumption in buildings.
