Polycarbonate sheets may yellow over time, which is influenced by the material quality and the presence of protective coatings. Excelite’s clear polycarbonate sheets have UV coatings on both sides and come with a 10-year warranty.

Yes, clear polycarbonate sheets are more prone to scratching compared to some other materials, such as glass or acrylic. But we offer polycarbonate sheets with scratch-resistant coatings that can help improve durability and reduce the likelihood of scratches.

Polycarbonate sheet material is known for its high impact resistance and durability.  To drill holes in polycarbonate, use an ordinary iron or HSS drill bit. Position the drill perpendicular to the sheet and run it at medium speed, applying light pressure. A slightly used but sharp drill bit is best to avoid “biting” into the  material. 

And don’t drill too close to the edge.

The lifespan of Excelite® roofing  panels typically ranges from 10 to 15 years, depending on factors such as material quality, UV protection, environmental exposure, and maintenance. PC Sheets with UV-resistant coatings generally last longer.

No, polycarbonate and Perspex (acrylic sheet) are not the same. While both are transparent plastic materials, polycarbonate is more impact-resistant, tougher, and flexible, making it nearly unbreakable. Perspex, also known as acrylic, is more rigid and has a higher clarity but is more prone to cracking and shattering under impact. Polycarbonate is better suited for applications requiring durability and impact resistance, whereas Acrylic is often chosen for its optical clarity and scratch resistance.

With proper installation and maintenance, polycarbonate corrugated sheets typically last 10 to 20+ years, depending on thickness, UV protection, and environmental conditions.

Polycarbonate sheets are recyclable and have a long service life, which reduces material replacement frequency. Their ability to reduce lighting energy consumption also contributes to sustainability.

Corrugated plastic sheets are available in clear, white, bronze, solar gray, and opaque colors. Color selection affects light transmission and heat control.

Clean periodically using mild soap and water with a soft cloth or sponge. Avoid abrasive cleaners or brushes that could damage the UV coating.

Thickness selection depends on span, load, and application. Roofing projects exposed to high wind or snow loads typically require thicker panels or closer support spacing.

Corrugated sheets are ideal for lightweight roofing and covers, while multiwall polycarbonate sheets offer improved insulation and structural performance for enclosed spaces like sunrooms and greenhouses.
