Enviro AAC Flooring Panel

Autoclaved Aerated Concrete (AAC) is a lightweight concrete substrate that has all the benefits of building with concrete but its light weight. The AAC Enviro Floor panels are 75mm thick.

Enviro and the Environment

  • Enviro is extremely energy efficient and produces no harmful pollutants during the production process.
  • 1 cubic m² of raw material makes 4-5 cubic m² of actually product saving mass earth production
  • Inert material is non hazardous and does not emit harmful gases or vapours
  • All the waste product product at point of manufacture is recycled back into the production process

Economics of Enviro

  • The thermal properties of Enviro are extremely efficient and should help Architects, builders and homeowners reduce their energy consumption.
  • Enviro is installed quickly and efficiently thence reducing vital building time during construction. The convenient sizes of the panel allows onsite cutting and wastage to be kept to a minimum.

 Noise reduction

  • 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. The energy-efficient porous structure produces sound absorption along with mechanical vibration energy dampening, giving new dwellings both privacy in a peaceful surrounding, making this product even more environmentally friendly.

Thermal efficiency

  • The porous structure of Enviro has an extremely superior R-value rating than that of other masonry substrates combined with the air flow cavity gives the ability to keep a home warmer in winter and cooler in summer giving the homeowner the added advantage of extra insulation in their home.
Key Features

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

Scope of Use

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.


Limitations on Use

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.
