Application

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).

Description

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 supporting structure can be a steel or plywood deck. Either deck is covered by Aludex Max (an aluminium foil-reinforced bituminous vapour barrier with a high water vapour resistance of 7000 MNsg) installed with cold or hot glued joints. All insulation materials must have a compression strength of minimum 50 kPa (0.5 kg/cm² ), at a maximum 10% deformation and must be dimensionally stable at up to 100°C and comply with current Building

Regulations.


Between the VMZINC PLUS and the insulation, a VMZINC Membrane is fixed with an overlap that varies depending on the slope. The insulation material must also comply with the fire resistance requirements of the Building Regulations.


Features and benefits:


  • BBA certified – 12/4900 product sheet 1.
  • 100 year service life following BRE EPP EN 15804
  • Weather tight to wind and rain.
  • Reduced thermal bridges.


System build-up:


  • Interior finish.
  • Rafters.
  • Continuous support (e.g. steel deck or plywood).
  • Aludex Max (fully supported vapour barrier).
  • Insulation (e.g. mineral board or PIR).
  • 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. 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.

Fasteners to substrate

It is recommended that screws be used to secure the clips with three being used per sliding clip. The use of nails offers significantly less resistance, but in the event of using nails, contractors are advised to use ring shank nails.
