3 mm Composite roofing sheets

Polycarbonate composite roofing sheet

Polycarbonate composite roofing sheets allow natural light to enter between insulated sandwich panels from manufacturers such as FALK, Joris Ide and REX, combining high light transmission with good thermal insulation.

They are lightweight, impact resistant and suitable for use on sloping roofs and façades. Composite roofing sheets are manufactured to specific project requirements with foam filling at the purlin positions.

Assembly instructions

Our systems are designed for seamless and efficient integration into any construction project. Thanks to project specific dimensions and clear technical guidelines, we guarantee a quick installation with a perfectly wind and watertight connection.


Optical Precision

Thanks to the unique combination of a 3mm outer panel and a 10mm inner panel, incoming natural light is filtered and diffused in a sophisticated manner. This layered design minimises glare and optimises the visual flow within the space, while maintaining a high light transmission of approximately 74% (in the transparent version).


Natural light experience

Despite its superior thermal insulation (U-value of 1.25W/m².K), the composite roofing sheet offers unrivalled colour fidelity for an insulated unit. The incoming light retains its natural character, enriching the interior environment with a sense of vitality and an authentic representation of materials and textures.
