In recent times an increased focus has been placed on the cost of construction, the impact on the environment and sustainability of products. MasterWall systems measure up in more than one way in this regard. Lightweight products are cheaper to transport and quicker to install, hence saving on carbon fuelled transport all the way.

EPS brings considerable energy and resource-saving benefits, making it a smart and sustainable choice for building and construction applications.

The manufacture of EPS uses less than 0.1% of global crude oil as a feedstock. However, it can deliver up to 200 times its own resource in thermal energy savings.

The following characteristics of EPS enable it to minimise both environmental impacts and costs:

EPS packaging achieves significant transport savings compared to other packaging materials due to its light weight, resulting in lower fuel consumption. Its exceptional cushioning and thermal properties result in lower damage rates and maintain a secure cold chain for temperature sensitive products.

EPS is one of the lightest of all construction materials allowing ease of handling and faster construction times. Its outstanding thermal insulation properties and durability ensure performance throughout the full lifetime of the building / construction application in which it is used.

EPS is recyclable at many stages throughout its life cycle.

Both panels used in the MasterWall systems are made from byproducts of the oil industry and lock them into high performance insulation foams. The resulting energy savings from the highly-insulated home completely reduce its carbon footprint over time. These carbon benefits are not just for a short period of time, but the life of the building. Building with Masterwall is not only smarter but a lot greener as well.

Estimating R Values
Thermal ratings of common wall construction materials.

As owners and builders become more conscious of the rising financial and environmental costs of energy, thermal efficiency is becoming increasingly important. Government energy rating standards of residential homes are an example of the initiatives that are driving the way we build and renovate.

Whilst buildings overall energy rating incorporates many different factors, core considerations are the thermal efficiency of the walls, ceilings and floors. Insulation of the building envelope keeps heat in during winter, but also keeps heat out during summer to improve comfort and save energy. A well insulated home can save an average of 20% of energy costs per year. Whilst design can certainly affect thermal efficiency, the correct choice of wall cladding materials is the single most important consideration.

An R rating of up to Rt 3.9 can be achieved with MasterWall’s 125mm polystyrene panel, stud frame and 10mm internal plasterboard.


Household Energy Bills- With and Without MasterWall.

Most people understand the long-term value of installing solar panels on the roof of their home, but it’s not necessarily the same case when it comes to insulating and weatherproofing. In winter, heat loss occurs through walls and ceilings that are poorly insulated, and gaps in floorboards and wall cavities are a major source of heat loss. To prove the point, Masterwall spent 12 months collaborating with one of its customers after installing the MasterWall system. Energy consumption pre and post installation was compared, with the results proving what the owners experienced day-to-day.

“Over the last 12 months I have noticed a huge change in the consistency of the temperature in the house when either the heating or cooling is on. The house remains warm in winter and cool in summer without the need for turning on the heater or air conditioner, day and night”. ~ Jo Chapple.

The results are even more dramatic given the household went from 2 adult occupants between November to May of the first year, to 3 adults thereafter. The MasterWall system is the leading system on the market that provides a total, weather-tight insulation solution; whilst at the same time significantly increasing the external design-value of your home.
