Performance
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.
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.
A U-value of less than 0.45 W/m2K can be achieved with the
standard 50mm thickness of external insulation in conjunction
with masonry, dense concrete, metal or timber frame wall
construction.
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".
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.
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.
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. 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.
Tests have shown that the brick slips will not detach under the
effects of hard body impacts up to 15 J. Localised damage may
occur in situations where the system is subjected to impact
energies above 7.5J.
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.
The Eurobrick Insulated Brick Cladding System is considered to
be durable for at least 60 years on the building on which it is
incorporated provided that the system is installed in accordance
with the requirements of the manufacturer and of this
certificate and that any accidental damage to the finish is
effectively repaired.
