Vented standing seam roofing.
Suitable for buildings in 1 to 4 humidity classes (dwellings with high occupancy, sport halls, etc) with pitches from 3° to the vertical.
Vented cold roof system for buildings with humidity classes between 1 and 4 using VMZINC Plus on a plywood (non-compatible) substrate.
VMZINC PLUS is installed on the plywood. A minimum 50 mm continuous air gap must be left clear beneath the plywood. Continuous ventilation openings are made at the ridge and eaves at least 10 mm wide protected by insect mesh and correspond to BS 5250: 2002.
VMZINC Membrane can be used between the VMZINC PLUS and the plywood, although this is optional but may have the advantage of protecting the plywood prior to the installation of the zinc. The ideal thickness of the plywood is 18 mm and it must be weather and boil proof. WBP plywood is more precisely described as EN 314-2 (bond class 2) and EN 636-2 (timber performance).
It is also recommended to install a vapour control layer on the warm side of the insulation.
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.
