On Myths Around Leaky Homes

More and more architects are now designing buildings using Masons Plastabrick's newest product Enviro AAC Panel and the Plastabrick System, both have a 20-45mm cavity which complies with the building practices outlined by the Department of Building and Housing.

Two factors in leaky buildings were:

'Mediterranean' Style buildings using Monolithic cladding systems were outside the product specifications
Inadequate construction that did not allow for deflection, drying and drainage of water or moisture.

Cavity systems are now recommended as they allow space for any moisture to evaporate and not sit on the framing. To help combat moisture Masons also supply a barricade window tape which is installed with all window and door openings.

Autoclaved Aerated Concrete (AAC) is a lightweight concrete substrate that has all the benefits of building with concrete but its light weight.

The panels are fixed to the floor framing of the building using galvanised bugle for timber framing or dual grip hexhead screws for steel framing. The panels are 600mm wide, with a dry density of 520 kg/m³, about 1/5th that of concrete. Enviro 75mm floor panels are available in standard length of 2200mm and upon request can be sourced in 1800mm panels.

Masons Enviro AAC Panel System has been evaluated by Certmark as meeting the following provisions of the NZ Building Code:

B1 Structure: B1.3.1, B1.3.2 and B1.3.4
