Masonry Overlay System
Description
The Masonry Overlay System is an exterior insulating and finishing system for concrete masonry, in situ or precast concrete walls.
The system consists of Graphex (Neopor®), expanded polystyrene (EPS), extruded polystyrene (XPS) or polyisocyanurate (PIR) sheets fixed to the concrete masonry or concrete walls with adhesive mortar and mechanical anchors. The plaster coating system consists of a 5 mm thickness of fibreglass mesh reinforced, polymer-modified, cement-based plaster, which is finished with a cement-based finishing plaster that is then painted with a 100% acrylic-based paint system. The chosen finishing plaster is applied to give a range of different appearances, such as a sponge, patterned, adobe or spray textured finish.
Scope
The Masonry Overlay System has been appraised as an exterior insulating and finishing system for buildings within the following scope:
- With substrates of concrete masonry, in situ or precast concrete up to 3 storeys with a maximum height from ground to eaves of 10 m.
- With floor plan area limited only by seismic and structural control joints.
- With supporting structures designed and constructed in accordance with the NZBC.
- Situated in NZS 3604 wind zones up to and including extra high.
The Masonry Overlay System has also been appraised for bond/fixing, durability and weathertightness of the exterior insulating and finishing system for concrete masonry, in situ or pre cast concrete buildings subject to specific design up to a differential design ultimate limit state (ULS) wind pressure of 2.5 kPa.
The Masonry Overlay System must only be applied on vertical surfaces except for sills, concrete-reinforced parapets and concrete-reinforced balustrades, which must have a minimum 10° slope and be waterproofed in accordance with the requirements of the technical literature and building designer.
Installation of components and accessories supplied by Resene Construction Systems and its approved applicators must be carried out only by Resene Construction Systems approved applicators.
