3. Types of masonry cladding
• Traditional brick and
block cladding
• Pre-cast brick panels
• Brick slip and brick tile
systems
• Pre-cast concrete, stone,
granite or slate panels

4. Pre-cast brick panels
These units are pre-cast and manufactured in
production plants away from the construction
site where they are to be used. These pre-cast
panels are usually much thinner in section than
traditional brick outer leaves and are fixed back
to the main structure or to themselves.

5. Brick slip and brick tile systems
This type of cladding consists of brick
slips or tiles of approximately 25 mm–
35 mm in thickness fixed to a pre-
fabricated panel which is in turn fixed
to the main structure.
The slips or tiles are fixed either by
using a special adhesive or by
mechanical fixing methods. All joint
finishing is normally carried out once
the installation is complete.
Joint finishing is achieved by pumping
a special cement-based mortar into the
vertical and horizontal joints and then
forming a joint finish in the normal way.

6. Supporting/fixing masonry
cladding (1)
The use of concrete support beams has become less
common since the introduction of metal support systems.
Continuous lengths of metal supporting beams can be
fixed to the structural concrete by purpose-made
expansion bolts or other specially designed channel bolts.

7. Supporting/fixing masonry
cladding (2)
In most instances, brickwork cladding will be supported
at each floor level when using metal support systems.

Alternative cladding methods
One method involves the
fixing of timber studs to the
main framework to which
individual brick course units
are secured.

11. Prevention of fire spread in timber
framed structures
Regulations require that for any timber frame
dwelling of two storeys or more cavities must be
closed at specified intervals with the use of
cavity barriers. The spacing and positioning of
these barriers will be identified within the
specifications and drawings.
The following illustrations show examples of
positioning of cavity barriers in timber frame
construction.
