Elevate V-Gard FR Roll
The Elevate V-Gard Vapor Control Membrane is designed to be used as vapor control layer in Elevate roofing systems. It consists of a reinforced aluminium foil with self-adhesive bituminous backing protected by a release film. The fiberglass reinforcement makes it suitable for applications that involve high mechanical stresses. The Elevate V-Gard membrane can be installed on concrete, wood and steel deck. Design and selection of an appropriate vapor control layer is the responsibility of the specifier.
Characteristics
▪ Total Vapor Control Layer
▪ Self-adhesive
▪ Cold applied without use of flames
▪ Excellent mechanical properties, resistant to heavy worksite traffic
The Elevate V-Gard membrane can be installed on concrete, wood and steel deck.

Preparation
Substrates need to be clean, smooth, dry and free of dust and sharp edges and other materials that may
damage the membrane. Metal surfaces must also be free from remaining processing oils. Verify if detailing of
the deck at roof edges and details is appropriate for installation of the vapor control layer. In case of adhered
roofing systems, all substrates except metal decks, if in conjunction with local regulation, must be primed with
Elevate SA-19 primer to improve the adhesion of the V-Gard membrane. Allow primer to dry completely
before installation of the V-Gard membrane. V-Gard membranes that have been exposed at temperatures
below 5°C have to be brought at ambient temperature prior to installation.
Application
V-Gard membranes can be installed at temperatures between +5°C and +45°C. Installation at lower
temperatures may cause difficulties to adhere.
Elevate recommends unrolling the V-Gard membranes onto metal decks in the same direction as the deck
and positioned so that side laps are fully supported. Unroll and position the membrane with release liner in
place for alignment. Stagger the membranes. Once aligned, peel back a portion of the release film and press
the membrane onto the substrate for final adhesion. All membranes should be broomed to fully mate them
to the substrate. Ensure proper adhesion in case of an adhered roofing assembly. Apply Elevate SA-19 Primer
in case V-Gard is not covered by insulation on the same day. Roll the overlaps individually and verify that all
capillaries are closed.
The vapor control layer should be inspected and repaired prior to installation of the insulation boards. It is
recommended cover the V-Gard membranes as soon as possible with insulation and roofing membrane.
