Each individual Vent3® underlay product has the batten gauge & zonal application for wind uplift printed on this packaging.
The manufacturers declared values are available from the Cromar website.
The Vent3® underlays may be used at any batten gauge in all wind zones when laid over nominally air-tight sheet sarking for example OSB, plywood, chipboard and insulation for warm-roof design.
They may also be used in applications where slates are nailed directly onto sarking boards.
Sarking boards, such as square-edged butt jointed planks, are not considered to be air-tight and the underlay is treated as unsupported.
