Do you get any
dampness in your home or an outside building structure? This can be one of the
most difficult and expensive defects to correct. With the majority of moisture
problems arising from condensation and water penetration through windows, doors
and roof abutments, preventative measures need to be put into place. But it can
be confusing to know when cavity trays and weep vents are required to keep
What is a cavity tray?
A cavity tray is
essentially a damp-proof course (DPC) that crosses the cavity of a cavity wall
in order to prevent dampness from permeating the internal skin of a wall.
Cavity trays are a
unique range of single-element systems that I can install to solve a damp
problem. They are lightweight, simple to install and long-lasting solutions to
the prevention of damp from penetrating below the roof line. This works by
stepping up between the outer and inner leaves, to form a gutter which leads to
a weep vent in the outer leaf.
What are cavity trays used for?
Cavity Trays can be
used in a variety of applications. Where the external wall changes to that of
an internal partition below the roof line some examples could be.
A gable abutments on
new build or a lean-to extension on refurbishment projects the building must be
protected from water penetration.
Where a flat roof is
resurfaced or reconstructed with extra insulation, the roof level may be raised
resulting in the skirting and damp proof course being lifted, therefore leaving
room for water and damp to seep in.
trays are fully compatible with all building materials, with the largest
bridging piece catering for cavity widths from 50mm to 100mm, enabling
flexibility of design and installation for a specifier and builder.
Cavity Trays Refurbishment
Cavity trays can be
used as a refurbishment system, whereby they are folded to facilitate the
insertion of a new tray into an existing wall or to replace old, poorly
constructed cavity trays. For example, where a new lean-to extension meets an
existing building, the original external wall becomes an internal partition
below the roof line and must be protected from damp and penetration of
Or when a flat roof
is resurfaced with added insulation or is reconstructed as an inverted roof
with top paving, the roof level may be raised, thus requiring the skirting and
its corresponding damp proof course to be lifted.
In addition, existing cavity trays that have been
poorly installed or have eroded allowing water to leak through and will need to
