use
To provide flashing and ventilation
at roof and wall intersections.
introduction
Where a monopitch roof abuts a
masonry wall there is a
requirement to provide ventilation
of the equivalent of a 5mm
continuous gap.The Type VF
Ventilating Flashing is
manufactured from British
Standard lead to which is bonded a
breathing base layer that permits
air to enter and exit.
When correctly incorporated at the
roof /wall intersection,and flashing
can provide the airflow requirement.
Thus the Type VF Ventilating
Flashing looks like and may be
substituted in preference to
ordinary flashing.It offers the
advantage of permitting a roof to
breathe – naturally..Always make
provision for air travelling via the
flashing to reach the intended parts
of the roof.
