Eurobrick
Brick Cladding Specification & Brick Slip Systems
1.1 Description of Product
1.1.1 EuroBrick Insulated Brick Cladding System
is assessed for use as weather resistant, thermally insulating
decorative exterior finish. The standard system comprises 50mm thick
extruded polystyrene foam insulation boards bonded to a polystyrene
vacuum formed skin. The skin provides a precise horizontal joint
spacing track for 15mm thick fire clay brick slips which are applied
by EuroBrick Systems Limited supplied adhesive. The vertical and
horizontal joints between the brick slips are grouted with EuroBrick
Systems Limited supplied premixed cement based mortar.
1.1.2 The bonded polystyrene insulation with
vacuum formed skin is supplied in panels 1200mm by 2400mm. The
panels have a tongue and groove on the long dimensions, the
horizontal joint track being at right angles to the long edges, and
are delivered to site in shrink wrapped packs. The adhesive is
supplied in sausages, the brick slips are delivered boxed and the
grouting mortar is supplied in 25 kg bags.
1.1.3 Mechanical fixings for fixing to timber,
metal or masonry are supplied by EuroBrick Systems Limited for
fixing the polystyrene panels to the masonry, dense concrete, metal
or timber substrate.
1.2 Product Performance
1.2.1 EuroBrick Insulated Brick
Cladding System will provide a weather resistant external wall
insulation cladding with a brickwork appearance for masonry, dense
concrete, metal or timber frame construction.
1.2.2 EuroBrick Insulated Brick Cladding System
will provide additional thermal resistance to an existing wall of
0.49 m2K/W. The thermal conductivity of the layer of polystyrene
insulation has been measured as 0.026 W/mK.
U-Values of 0.33W/m2K and 0.31W/m2K can be
achieved when insulating 225mm solid wall and 275mm cavity wall
respectively with 75mm backer panel.
1.2.3 Tests have shown that the EuroBrick
Insulated Brick Cladding System will limit the amount of water able
to reach the substrate. The cladding can be classified as Type 4
insulating cladding for impermeability to water, as defined in UEAtc
MOAT No 45. It is considered that the cladding system is suitable
for geographic areas including those classified as having “very
severe” exposure to wind driven rain, when assessed with reference
to BS 5628: Part 3: 1985 and BS 8104:`1992. Reference must be made
to BRE document BR 143 “Thermal Insulation-Avoiding Risks”.
1.2.4 The cladding, when tested for surface
spread of flame in accordance with BS 476: Part 7: 1987, and to BS
476: Part 6: 1983, achieves a Class O rating with respect to the
appropriate Building Regulations. There will be a maximum surface
area restrictions for the system for use near to other unprotected
areas or to boundaries, as detailed in Section 2 below. EuroBrick
Insulated Brick Cladding System must not be considered as providing
any contribution towards the overall fire resistance performance of
a wall.
The insulation boards must be separated by
horizontal fire barriers at intervals of not less than the line of
every other floor in the construction from the second floor, except
in England and Wales where there is no such requirement unless
deemed a compartment wall/floor. The fire barriers must be applied
in accordance with the instructions of EuroBrick Systems Limited.
1.2.5 The EuroBrick Insulated Brick Cladding
System has a vapour resistance of 130 Mns/g. Calculations performed
in accordance with BS 5250:1989 show that under conditions typical
for the UK, interstitial condensation will not occur within the
system with 50mm standard thickness insulation for masonry, dense
concrete, metal or timber frame construction. With metal and timber
frame construction, where additional insulation is installed between
the frame, it is essential that any vapour barrier on the warm side
of the structure is fully effective.
1.2.6 Tests on the EuroBrick Insulated Brick
Cladding System have shown that the system has adequate resistance
to the forces of wind suction and pressure for locations where the
basic wind speed is up to 52 m/s in accordance with CP3: ChapterV:
Part2: 1972. Variations in temperature and moisture content will not
cause detachment of the brick slips and grout from the insulation
panel over the range of operating temperatures that may be
anticipated in the UK subject to expansion joints being provided.
The system is resistant to cyclic freezing and thawing action and
after prolonged exposure to such conditions exhibits no detachment
or spalling of the brick face.
1.2.7 Tests have shown that the brick slips will
not detach under the effects of hard body impacts up to 15J.
Localised damage may occur in situations where the system is
subjected to impact energies above 7.5J.
1.2.8 When installed in accordance with the
manufacturer’s instructions and the requirements of this
certificate, no dust or insects should be able to penetrate through
the system.
1.2.9 The EuroBrick Insulated Brick Cladding
System is considered to be durable for at least 30 years on the
building on which it is incorporated provided that the system is
installed in accordance with the requirements of the manufacturer
and that any accidental damage to the finish is effectively
repaired.
2. Technical Appraisal
2.1 Performance Tests
Tests and inspection of test data have been
carried out to determine the properties and performance of the
EuroBrick Insulated Brick Cladding System for:-
-
Wind loading
-
Durability
-
Adhesion between layers
-
Performance in relation to fire
-
Resistance to water penetration & water
vapour
-
Transmission
-
Resistance to impact
-
Resistance to cyclic freezing & thawing
-
Resistance to thermal & moisture cycling
Some of the results are outlined in Table 1
below.
Assessment has been made of the products and
practicality of installation. Buildings recently clad with the
system have been inspected.
Eurobrick also produce a range of Brick Slips and
Brick Slip Systems.
