Clients expect innovative buildings with environment-friendly designs, low energy consumption and low heating costs. Planners are therefore encouraged to design solid building structures that are not only economical to build, but also economical to maintain and that preserve their value over the long term.
Clay, water, fire and air
The perlite-filled Porotherm blocks meet all these requirements. They are made from the natural elements of clay, water, fire, and air. Once processed, the lightweight, perlite volcanic rock forms a natural insulating material. With thermal conductivity of 0.07 to 0.09 W/(mK), the single, monolithic wall of filled Porotherm blocks does not need any additional thermal insulation in order to meet current energy standards. This also means lower maintenance and construction costs. A further advantage of the solid, but slimline masonry is that it leaves more internal living space.
The exceptional properties of the product provide optimum thermal, humidity and acoustic insulation, making it suitable for buildings constructed in accordance with the passive house standard. It is classified as a Class A1 product for fire protection, meaning that it is not flammable.
Healthy living guaranteed
Since 2008, Wienerberger has submitted its perlite-filled Porotherm bricks to the German eco-INSTITUT for environmental testing every two years. In 2018 the product was awarded the “mineral construction product” label for the fifth time. The eco-INSTITUT label is a recognised mark of quality for products that have to meet stringent requirements for pollutants and emissions, in accordance with the latest international scientific and research standards. The Porotherm bricks ensure a healthy standard of living, are not susceptible to mould, and do not give off any harmful fumes (such as VOCs, formaldehyde, etc.). Even once their service life is over, the demolished materials – as mineral rubble – can be disposed of cost effectively as Class 2 Eluates, or returned to the product cycle with low energy consumption.
