BE_VMZINC_Standing seam_Warm_Facade_Over MINERAL WOOL insulation

This non-ventilated cladding system allows ZINC PLUS standing seam cladding to be installed on a continuous insulating substrate of rigid mineral wool. Non-ventilated cladding is a composite system that does not require a ventilation gap beneath the zinc. The zinc is therefore installed directly onto its substrate. This requires the use of ZINC PLUS. VMZINC’s ZINC PLUS is coated on the underside with a white protective layer of organic composition which provides resistance to abrasion caused by the expansion of the zinc at the fixing points. Installation is simplified as there is no need for ventilation inlets or outlets.

The standing seam is aesthetic, modern, and offers uniform, low-profile joints (25 mm high with a thickness of 5 mm).

Packaging: The zinc is delivered in rolls to be profiled or in preformed strips on demand.

Surface aspects: ZINC PLUS 0,7mm and 0,8mm (available in Naturel PLUS, QUARTZ-ZINC® PLUS, ANTHRA-ZINC® PLUS, PIGMENTO® PLUS, AZENGAR® PLUS and lacquered Zinc PLUS), together with the entire product range, are classified A1 and do not contribute to fire spread. Lacquered finishes are classified A2. The cladding system achieves a fire classification of C-s3,d1 or B-s3,d1 in accordance with SBI test report 2390C WRGENT. According to the test conditions, the insulation must achieve at least a D reaction-to-fire classification.

The use of the chosen aspect may not be suitable for certain applications in the context of very aggressive environmental constraints. It is recommended, if necessary, to consult the VM Building Solutions services for further information.
