Warm, non-vented standing seam roofing.
The system can be used for roofs with a pitch from 3 to 70º and for buildings with humidity classes of between 1 to 4 (dwellings with high occupancy, sport halls, etc). The Metdeck/Warmdex must be completely dry before, during and after installation
Non-vented warm roof system for buildings with humidity classes between 1 and 4 using VMZINC Plus and an engineered panel as a substrate.
The substrate of the Metdeck/Warmdex composite panels (on the warm side of the roof panel) must be covered with Aludex Max a continuous aluminium foil-backed bituminous self-sealing vapour barrier. Condensation risk must be assessed for each individual project or individual project component in accordance with BS 5250: 2002. Specification may need to be adapted to the internal humidity load of the building.
The VMZINC Membrane should be installed between the VMZINC PLUS and the Metdeck/Warmdex composite panels, then dressed into the gutter.
Metdeck/Warmdex composite panels, incorporating 18 mm WBP plywood factory-bonded to a Resol insulation core, are mechanically fixed to the substrate (vapour barrier on concrete, metal or timber deck). The number of fixings required will vary with specific building details and geographical location, and must be assessed on an individual basis.
Features and benefits:
System build-up:
VMZINC PLUS:
A product which allows zinc to be installed on ventilated plywood as well as specific warm (non-ventilated) substrates. The product consists of VMZINC (in all finishes) having a 60 μm coating applied to the underside thus allowing a more varied amount of substrates to be used and eliminating the risk of the formation of white rust on the underside of the zinc standing seam panels. VMZINC PLUS resists to an abrasion of 140 L when tested in accordance with ASTM D 968.
Life Cycle Analysis (LCA):
VMZINC undertakes Life Cycle Analysis (LCA) tests on its products and publishes Environmental Product Declarations (EPDs), such as BRE Environmental Profiles. These provide users with comprehensive, reliable and transparent information on relevant environmental characteristics. The information is also used by VMZINC as the basis for its eco-design approach.
