Enviro Floor Panels have the following material properties:
Dry Density | 525 kg/m3 |
In Service Density |
600 kg/m3 |
Compressive Strength 4.0 MPA | 4.0 MPA |
Bending Strength | 780N – 1000N or above |
Dry Shrinkage Value | 0.8mm/m – 0.03% – 0.05% or 0.3-0.5mm/m |
Water absorption (by volume) | Up to 30-35% |
Thermal conductivity | 0.12 w/mk – 0.13 w/mk |
Thermal resistivity | 0.56 m2 k/w |
Sound Transmission Loss | 35dB for 1000Hz |
Fire Resistance | 1.5hours – 2 hours |
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.
This system will provide waterproofing to the wall surfaces when properly painted, however it is the responsibility of the designer and builder to provide and install adequate detailing for penetrations and tops.
Masons Enviro AAC Panel System has been evaluated by Certmark as meeting the following provisions of the NZ Building Code:
1m³ of raw material makes 4-5m³ of finished product. Waste from manufacture is recycled back into production. Enviro AAC Panel is non-hazardous, no harmful pollutants are used during the production process.
Enviro AAC has the unique ability to absorb noise and has a sound insulation value 7dB greater than other solid building materials of the same weight per surface area.
Since being established in 1999, Masons has become a key supplier in the New Zealand building industry, offering a variety of quality systems and products for a whole range of building requirements.
