Multiwall (Hollow) Polycarbonate Sheet
Multiwall Polycarbonate, also known as Hollow Polycarbonate, is designed for projects that need natural light while reducing heat transfer more effectively than standard flat sheet options. Its internal air-cell structure helps improve insulation performance, making it a popular material for skylights, pergolas, linkways, atriums, greenhouses, patio covers, and facade daylighting systems.
This material is widely appreciated for its balance of lightweight handling, UV protection, light diffusion, and weather resistance. In many commercial and residential projects, multiwall sheets help create brighter spaces while lowering direct heat gain compared with more transparent glazing options. Specs Polymer supports multiwall installations with installer-ready accessories including H-joiners, U-caps, and suitable finishing components, giving customers a more complete and reliable roofing or daylighting system.

Q & A
1. What is Multiwall Polycarbonate Sheet used for?
Multiwall Polycarbonate Sheet is commonly used for skylights, pergolas, greenhouses, linkways, atriums, and covered outdoor areas. It is ideal for applications that need natural light together with better heat insulation.
2. What makes Multiwall Polycarbonate different from Solid Polycarbonate?
The main difference is the structure. Multiwall Polycarbonate has hollow air spaces inside the sheet, which help improve thermal insulation and reduce heat transfer. Solid Polycarbonate is clearer and stronger in appearance, while Multiwall is better for lightweight roofing and daylighting needs.
3. Why is Multiwall Polycarbonate suitable for skylights?
It is suitable for skylights because it allows natural light into the space while helping reduce direct heat compared with more transparent flat-sheet options. This makes indoor areas feel brighter and more comfortable.
4. Is Multiwall Polycarbonate lightweight?
Yes. One of its key advantages is its lightweight structure, which makes handling, transportation, and installation easier for many roofing and canopy projects.
5. Can Multiwall Polycarbonate help reduce heat?
Yes. Its hollow internal structure helps improve thermal insulation, making it a preferred option for projects where customers want daylight without too much heat gain.
6. Is Multiwall Polycarbonate suitable for pergolas and linkways?
Yes. It is widely used for pergolas, linkways, patios, and covered walkways because it offers a practical balance of natural light, lower heat transfer, and weather resistance.
7. Are there UV-protected options for Multiwall Polycarbonate?
Yes. UV-protected options are available for outdoor use, helping improve long-term durability when the sheet is exposed to sun and weather.
8. What accessories are usually used with Multiwall Polycarbonate?
Multiwall Polycarbonate is often installed together with H-joiners, U-caps, and matching trims or flashing components to achieve a cleaner finish and more complete installation system.
