SureCav25 Features ● Ensures a consistent 25mm clear-cavity

Designed to protect ● Cavity protected from mortar and moisture

● Helps to drive down U-Values

SureCav25 is a lightweight cavity-spacer

Outstanding features that benefit:
● Site management
● Protection of the fabric of the building

1. Removes the need for a concrete block
backing wall when building with stone or
flint. SureCav25 is a lightweight alternative
that is easy to transport and move around
the site and will give you a cheaper, quicker
build.

2. Ensures a consistent 25mm clear residual
cavity. The cavity air space has been an
essential feature of buildings for decades
and has proved its worth in helping to
protect the fabric of the building.
SureCav25 upholds this proven ‘clear-
cavity’ approach.

3. Provide a protected cavity environment
that remains free from mortar, completely
removing the risk from contaminated wall-
ties and the dangers of moisture bridging
the cavity.
4. Forms a complete barrier, preventing
moisture from penetrating the outer leaf
and protecting from wind-driven rain in all
exposure zones (BBA 04/4154)

5. Features a unique groove that is designed
to direct any moisture that, in the unlikely Outer Insulation
event of breaching the cavity, will be masonry leaf
directed back to the outer face and drained
through weep vents.

6. Allows for an additional 25mm insulation in a 100mm overall cavity that helps to drive
down U-Values. 75mm of insulation in a 100mm overall cavity can achieve 0.18 W/m2K
7. Can provide up to 1.5% additional floor space in a 2 storey house when using the original
external dimensions. That’s equivalent to adding one extra house on an 80 house site.
