VMZINC Standing Seam Roofing - Standing Seam Roof On Metal Faced Panels (Warm, Non-vented)
Verified by manufacturer 4 months ago
Warm, non-vented standing seam roofing.
Application
Suitable for buildings in 1 to 4 humidity classes (dwellings with high occupancy, sports halls, etc) and with pitches from 3 to 70°.
Description
Non-vented warm roof system for buildings with humidity classes between 1 and 4 using VMZINC Plus and an insulated metal panel as a substrate.
The insulated metal-faced composite panel must be made from galvanized steel on both the internal and external facing (minimum thickness 0.7 mm for external facing). Fixings and clips must not inhibit the required expansion and contraction of the VMZINC PLUS or cause any damage to the protective coating underneath.
The insulated metal-faced composite panel must provide a 100% vapour barrier. This is normally achieved using a panel with a vapour tight interlocking jointing system.
Features and benefits:
- BRE EN 15804 EPD.
- This solution provides good pull-out resistance
- Offers a fast track installation process over large areas.
- Reduced thermal bridges.
- Allows building to be temporarily weatherproofed rapidly.
System build-up:
- Interior finish.
- Steel purlins.
- Insulated metal-faced panel (0.7 mm steel thickness).
- Aluminium-faced tape .
- VMZINC Membrane.
- VMZINC PLUS Standing Seam.
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, available from our website www.vmzinc.co.uk and www.greenbooklive.com. 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.

Colour | Natural VMZINC®. Guidance for specification option: Only available with Natural finish option. Natural VMZINC has a shiny metallic appearance when new and develops a patina over time. In facade applications, it may take 10 years for the matt grey patina to form. It can be quickly soldered without removing the patina. Standard PIGMENTO® BLUE. Standard PIGMENTO® GREEN. Standard PIGMENTO® BROWN. Standard PIGMENTO® RED. Standard PIGMENTO® GREY. PIGMENTO® STORM GREY. PIGMENTO® CHARCOAL GREY. QUARTZ-ZINC®. Guidance for specification option: QUARTZ-ZINC offers an appearance and texture that does not change over time. When QUARTZ-ZINC is scratched, it will self heal. The grey tones of QUARTZ-ZINC blend well with existing construction materials – ideal for refurbishment. ANTHRA-ZINC®. Guidance for specification option: ANTHRA-ZINC with its visible grain matches the colour of slate and blends well in combination with photovoltaic panels. AZENGAR®. Guidance for specification option: AZENGAR is the surface finish from VMZINC which is the first engraved zinc giving a product with a matt, heterogeneous and light aspect. AZENGAR can be used in the same fashion as other VMZINC products for both roofs and facades. |
