Masons Enviro AAC Panel Floor System
Description

A solid yet lightweight floor panel, Enviro™ provides a solid, premium feeling underfoot. Compared with timber-based flooring products, Enviro helps create quieter and thermally comfortable interiors.

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

Key Features
  • Weight: Strong and lightweight — Enviro has many of the features of a solid concrete floor, but without the weight for handling or loads on the structure. With a working density of 650kg/m³, it’s approximately one-fourth of the weight of concrete. Fitted over timber or steel joists, the span tables offer KPA floor load solutions for homes and offices. Self-levelling floor topping may be used to complete the installation or when the floor covering requires it.
  • Efficient: Simple to install — The Enviro Panel Floor System can be installed quickly and efficiently by screwing and glue-fixing each panel to the floor framing, using galvanised bugle screws for timber framing or dual-grip hex-head screws for steel framing. Panels are then mortared together with Masons Enviro ACC glue mortar or bonded with construction adhesive, creating a continuous lightweight masonry floor. The panel sizes may require a slightly different joist set-out than timber-based products to enjoy the full benefits of the system.
  • Clean: Low environmental impact: The Enviro Panel Floor System is energy-efficient, with no harmful pollutants produced during manufacturing. Its inert material is non-hazardous and does not emit harmful gases or vapours. All waste product at point of manufacture is recycled back into the production process.
  • Acoustics: Reducing sound between floors — Enviro panels are effective at absorbing noise and reducing sound transmission between floors, with an STL rating of 35dB for 1000Hz. The porous structure provides sound absorption, along with mechanical vibration energy dampening to reduce sound travel between rooms. See the sound performance table for details.
  • Economics of Enviro — Enviro's thermal properties are extremely efficient, which should help architects, builders, and homeowners reduce their energy consumption. Enviro is installed quickly and efficiently, reducing vital building time during construction. The panel's convenient sizes allow onsite cutting and wastage to be kept to a minimum.
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.
