Corrugated Multiwall Polycarbonate Products

Modular system of corrugated UV protected multiwall polycarbonate for translucent curtain walls and roofing.

arcoPlus® 1000 is a modular corrugated system consisting of 3 coextruded polycarbonate walls, in 8÷12mm thickness, perfectly overlapping lengthwise and enabling continuous coverage and skylights filled gutter.

Considering the linear thermal expansion of polycarbonate, to avoid cracks at the through fixings the recommended maximum length is 5,000mm.

Easy and Low-Cost Installation

To ensure compliance with snow load and negative wind load resistance requirements, anchor brackets should be fitted for each purlin.

The polycarbonate panels are fastened to the underlying structure using specific brackets, which must be anchored to the purlins using suitable self-drilling/self-tapping screws (on metal structures) and tap bolts (for wooden structures). These screws and bolts are not supplied.

Different connector profiles can be used, depending on the required load specifications.

Skylight Gutter Ridge Application

Panels laterally overlapping insulated corrugated metal roofing panels. Thanks to the specific design of the profile the system is perfectly compatible for overlapping all the main types of panel.

Minimum slope 5%.

Application Non Continuous Roofing

Construction of continuous roofing/wall with continuous lateral overlapping of polycarbonate panels. For roofing, recommended minimum slope 7%.


arcoPlus®1000 is a complete system for the construction of translucent curtain walls/roofing. It includes a range of accessories that make it suitable for all purposes. In addition to complete fastening assemblies, the system includes a tongue and groove seal, a flat strip for sealing overlap areas, a range of steel profiles including bracing brackets, and a special press-formed profile to be inserted as a reinforcement on the groove side of the panel. For continuous roofing the panels are arranged with a continuous lateral overlap.

A flat ridge to place over the adjacent ridge profiles completes the range of accessories. Standard panels are supplied
with heat-sealed ends to prevent soiling inside the air cells.
