Fresh external appearance
SureCav25 provides an excellent opportunity to
upgrade to external face of older building stock
or provide a protective moisture barrier behind
the render system on timber-frame dwellings.
The unique features of SureCav25 form a barrier
to wind-driven rain and will further protect the
fabric of the building. A vented, SureCav25 cavity
will be able to ‘breathe’ and evaporate the
moisture, avoiding the problems of interstitial
condensation.

With the installation of a unique SureCav25
airspace over the top of a degraded wall surface
it is now possible to build a new decorative,
waterproof rendered surface.

Use insulation render boards or cement fibre
boards, following the manufacturers
standard fixing instructions. Complete the
upgrade with your preferred render system.

The unique design of SureCav25 forms a
barrier to wind-driven rain and will further
protect the fabric of the building. This allows
the original cavity to be filled yet still ensure
a barrier to prevent moisture from crossing
older deteriorating ties.

SureCav25 is made from 100% recycled
polypropylene that will last the lifetime of the
building.

Full BBA certification confirms the suitability of
the SureCav25 Spacer System for all types of
building construction.
