Load Resistance

Calculation and Installation

Easy and Low Cost Installation

Realization of vertical translucent curtain walls

The 40mm-thick, 4 walls design with tongue and groove connection gives the panels remarkable flexural strength. It also allows the panels to be installed without the use of metal reinforcement frames (continuous windows), thus eliminating heat loss due to the thermal bridges caused by these structures (discontinuous windows).

For installations exceeding 2.2m, a suitable section-breaker profile must be installed to which the arcoPlus® panels can then be fixed.

This is done using the specific brackets to give the system the necessary resistance to negative wind load and permit sliding due to thermal expansion (see load resistance graph).

Examples of Panel Length

Accessories

The arcoPlus® system includes a complete range of aluminum profiles for installing the panels.

The air cells of the polycarbonate panels must be sealed using vented aluminum breather tape. This allows correct ventilation and prevents soiling on the inside.
