- the cladding system is installed on timber framing that complies with NZS3604 protected by a building wrap and protected by a building wrap and pre-qualified window sealing tape that complies with Table 23 of E2/AS1 and BQI interim Performance Standard BQI C4021*.
- the render is protected from the weather with a coating system complying with BQI interim Performance Standard C5031*.
- MCL StuccoRite® Cavity Wall Cavity System (known as MCL StuccoRite®) and when installed according to the MCL StuccoRite Technical Manual dated January 2006, will meet the following performance requirements of the Building Code:
- the present invention is an evolution of that system.
- the current system of the invention comprises proprietary plaster, reinforced with pre-papered hot dipped galvanised zinc steel wire MCL® StuccoRite® Mesh Sheet and other reinforcement, to achieve a nominal thickness of 21 mm with a standard sponge or plastic float finish.
- the plaster is applied by MCL® StuccoRite® Mortar Pumps over the mesh which is stapled to 35mm x 40mm nominal sized H3.1 or H3.2 treated vertical timber battens providing a ventilated and drained cavity.
- the proprietary plaster is applied in three coats; a base coat, a levelling coat, and the top coat.
- the base coat encapsulates the pre-papered MCL® StuccoRite® Mesh Sheet reinforcement as well as additional reinforcement at corners and around joinery.
- the levelling and mesh coat contains further reinforcement in the form of fibreglass mesh (MCL® Fibreglass Mesh).
- the final skim coat is sponge or plastic float finish.
- the MCL® StuccoRite® Mesh Sheet is fabricated from copper bearing cold drawn hot dipped galvanised zinc vertical face wires and horizontal back wires, electrically welded at all points of intersection.
- the zinc coating is not less than 27.9g/m 2 .
- the face and back wires are 1.5mm diameter with openings not exceeding 51mm.
- a layer of absorptive, slot perforated paper is placed between the face and back wires.
- the mesh is self furring by being fabricated horizontally into the lath at 152mm centres with a 6.5mm crimp in each face wire at its intersection with double back wires.
- a layer of Type 1, Grade D, Style 2 black building paper in compliance with UBC Standard No. 17-1 is strip glued to the back of the high absorbent slot perforated paper and is extended 100mm beyond the lath at the left end of the sheet and 100mm beyond the upper long edge of the sheet.
- MCL® uPVC Kwik corners being a 55mm x 55mm angle with nosing and MCL®uPVC Kwik flanges, being 65mm x 15mm angles with nosing, provide reinforcement at window and door openings.
- MCL® Fibreglass Mesh is contained locally at certain openings in the base coat and continuously in the levelling and mesh coat.
- the MCL® Fibreglass Mesh is alkali resistant and woven with a 4mm x 4mm aperture weighing not less than 165 grams per square mere.
- the edges of the plaster are formed and supported by a number of uPVC mouldings.
- the MCL® Bottom J-Mould with Drip Edge and the MCL® Window/Door head with Drip Edge also provide vermin proofing and allow for drainage and ventilation to the cavity.
- Movement is accommodated by providing physical breaks in the plaster. This is achieved with a uPVC moulding for the vertical movement control joint (VMCJ) and with a uPVC window head moulding and Z flashing for the horizontal movement control joint (HMCL).
- VMCJ vertical movement control joint
- HMCL horizontal movement control joint
