Cellular polycarbonate (PC)

The ideal material for lightweight roofs and durable enclosures

The material

Cellular polycarbonate: lightness, insulation and durability for roofs and enclosures

Cellular polycarbonate is an engineering plastic widely used in construction applications, enclosures and roofing. Its honeycomb structure gives it excellent insulating capacity and outstanding impact resistance, with a much lower weight than other plastic materials. At Plásticos Ferplast, we specialise in the supply and machining of cellular polycarbonate sheets, available in different thicknesses, colours and formats. We recommend this material for projects where a combination of durability, lightness and energy efficiency is required, such as roofs, facades or skylights.

Technical properties of the material

Frequently asked questions about cellular polycarbonate

What is a cellular polycarbonate sheet?

A cellular polycarbonate sheet is a panel made up of multiple layers joined by internal ribs that create a honeycomb structure. This design provides lightness, strength and insulating capacity, making it ideal for enclosures and roofing.

What advantages does cellular polycarbonate have over other materials?

Cellular polycarbonate combines strength, thermal insulation and low weight, making it an excellent alternative to glass or acrylic in roofs and facades.

Can cellular polycarbonate be made to measure?

Yes. We offer made-to-measure cellular polycarbonate, with cutting, machining or thermoforming adapted to the design and dimensions of each project.

What maintenance does a cellular polycarbonate roof require?

Maintenance is minimal: simply clean the sheets periodically with water and neutral soap to maintain transparency and remove residue.

Is cellular polycarbonate suitable for outdoor use?

Yes. The sheets include UV protection on one or both sides, preventing yellowing and ensuring a long service life even in high sun-exposure environments.
