Cova-Wall® Lightweight Polystyrene Wall Cladding

Lightweight polystyrene wall cladding provides structural protection and a decorative finish suitable for both residential and commercial applications. Aside from being a key element in the aesthetic appeal of a building’s structure, lightweight polystyrene wall cladding helps control the infiltration of weather elements, provides an impermeable vapour barrier, with acoustic and thermal insulation.

Cova-Wall® is a lightweight External Insulated Finishing System (EIFS), composed predominantly of expanded polystyrene sheets. The system is reinforced with a base coat, a layer of fibreglass mesh, finishing coat for sealing and a choice of texture coating for finishing.

Compared to conventional cladding materials, lightweight polystyrene wall cladding gives the homeowners and builders the freedom of design with excellent dimensional stability and inherent structural strength.

The benefits offered by Cova-Wall® lightweight polystyrene wall cladding system consists of the following:

 

1. CodeMark™ Certified
Developed by the Australian Building Codes Board (ABCB), CodeMark™ serves as the guiding principle that tests product compliance based on local and international standards. Cova-Wall® lightweight polystyrene wall cladding system has been awarded its CodeMark™ certification, thus giving assurance to homeowners and builders the system is safe to use and meets the governing standards of the Australian building and construction industry.

2. Structural Stability
Expanded polystyrene is composed of rigid, closed cellular structure that contributes to its dimensional and structural stability. Its impermeable surface is resilient to premature degradation and has the ability to maintain its form and function, even after prolonged exposure to weather.

Aside from inherent strength, Cova-Wall® has been reinforced in the lightweight polystyrene wall cladding system by layering fibreglass mesh on top of the base coat and sealing it with a texture coating finish. Cova-Wall® has been tested and passed AS 1366.3 AS 4055 – 2012, for design wind speed and speed loads maintaining structural stability.

3. Thermal Insulation
Expanded polystyrene exhibits excellent acoustic and thermal insulation properties, attributed to its closed cellular matrix. In addition, Cova-Wall® lightweight polystyrene wall cladding system has high R-values, providing optimal insulating capacity and long lasting performance.

4. Weatherproofing
Formulated and designed for a higher degree of resistance to natural elements, Cova-Wall® lightweight polystyrene wall cladding is manufactured in compliance to AS/NZS 4284:2008, the Standard that determines the performance of a building facade under simulated loading conditions. The use of expanded polystyrene sheets boosts performance by providing a protective layer that inhibits water and vapour from infiltrating the substrate.

Hi there,

Sorry but this product has a fire retardant added but it’s not fire proof.
