Enviro AAC Panel Cladding and Floor Systems

Whether you're enhancing the exterior cladding or flooring of your residential or commercial spaces, Enviro offers a strong, lightweight, and cost-effective solution that stands up to New Zealand's diverse climate. 

Enviro panels are made of autoclaved aerated concrete (AAC), with steel reinforcing through the centre. Air cells in the concrete absorb and reduce noise, making interior spaces far quieter to live and work in when compared with timber-based alternatives. With its high thermal mass, Enviro helps balance indoor temperatures, absorbing heat and then releasing it as a building cools down.

Enviro AAC Panel Cladding System

Cost-effective and quick to install, Enviro is a strong, lightweight exterior cladding panel for residential and commercial buildings. With an aerated concrete core, Enviro flashings for weathertightness, and Masons’ plaster applied over the top, the system provides strength, weathertightness, and timeless design.

Benefits of the Enviro™ cladding

WEIGHT: A strong, lightweight cladding system

With a working density of 650 kg/m³, Enviro panels are about one-fourth the density of concrete. Panels are easy to cut and quick to install for cost-effective cavity-based construction. The Enviro cladding system is suitable for all seismic and wind loadings around New Zealand when installed in accordance with the manufacturer’s instructions.

ACOUSTICS: Noise reduction

Enviro panels are effective at absorbing noise, attaining an STL of 33dB for 1000Hz. The porous structure, combined with the panel’s mass, dampens mechanical vibration energy and sound, assisting with acoustic privacy and quieter spaces inside homes and offices.

THERMAL: Suitable for NZ’s climate

The porous structure of Enviro provides an R-value of R.416. Although this must be derated by .45 for the cavity air gap, this rating helps the designer achieve a good wall thermal performance, making the system suitable for New Zealand climate zones from the warm north to the cool south.

CLEAN AIR: Low environmental impact

Enviro panels are energy-efficient in production, with no pollutants created during manufacturing. The 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. Mineral plaster at a thickness of 1–3mm is applied after panel installation.

WATER MANAGEMENT: Flashing and cavity systems

To prevent water from entering, the Enviro Panel Cladding System comes with a complete flashing system for windows and doors. If water should penetrate, Enviro has a ventilated cavity system to allow moisture to dry out and weep holes for water to drain out.

Enviro™ AAC Panel Floor System

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.

Benefits of the Enviro™ flooring

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.

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.

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.
