Non-vented warm roof system for buildings with high humidity levels using VMZINC Plus and a continuous support as a substrate.

FOAMGLAS cellular glass insulation is adhered to the substrate using a cold adhesive; the staggered joints of the board are closely butted with the cold adhesive ensuring a vapour tight seal (no vapour barrier is required).

Features and benefits:

Suitable for buildings with high humidity levels (including class 5, swimming pools).
BBA certified – 12/4900 sheet 2.
Almost no thermal bridges.
Excellent pull-out resistance.

System build-up:

Interior finish.
Metal purlins.
Continuous support (e.g. steel deck or plywood).
Cellular glass insulation (eg. FOAMGLAS).
Galvanized steel plates.
Bituminous membrane.
Polyurethane separation layer.
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). 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.
