Porotherm: perfect solution to the aerated block shortage

With the housebuilding crisis now firmly on the mend and building significantly on the rise, the construction industry is in the midst of an aerated block shortage. This could in part be due to aerated blocks being the preferred material to fulfil the 2013 building regulations. However, Porotherm clay blocks could be the solution. 

Manufactured by Wienerberger, Porotherm is a complete system with outstanding environmental properties that is both cost-effective and time-efficient to install. The clay blocks offer a highly efficient substitute to other building materials, such as aerated concrete blocks, timber or light steel frames, and can be used in load-bearing and non-load-bearing walls. 

The blocks are ideal for use on single to multiple storeys and for both domestic and commercial buildings. The Porotherm blocks are well designed and practical, but will need to be rendered with an external finish when being used on an outer wall to make them aesthetically pleasing. For internal walls, a plaster or plasterboard finish is ideal.

How easy are Porotherm clay blocks to use?

The system is extremely quick to build, easy and safe to use, very strong, incredibly efficient and environmentally friendly. This efficiency lies in the design of Porotherm's unique interlocking precision-engineered system, which negates the need for traditional cement, requiring only a thin layer of adhesive on the horizontal joints. 

As no cement is needed, the whole process is less messy and time is saved by not having to prepare the mix or having to wait around for one section to dry before getting on with the next. Using Porotherm clay blocks also produces a more consistent finish making walls appear sleek and smooth.

What are the sustainable benefits of using Porotherm?

Porotherm products are environmentally friendly and ecologically sound and the manufacturing and assembly processes also makes them kind to the environment. The blocks themselves are made from a mixture of natural clay and 30% of materials from alternative, recycled or secondary sources, such as paper and sawdust, which burn out during the manufacturing process. 

Additionally, the blocks have been awarded the Natureplus label, which is supported by Greenpeace and the WWF, and have a lifespan predicted to be over 150 years, making them one of the most sustainable complete building products on the market. 

The Porotherm building blocks also have great thermal efficiency, helping to maintain a consistent internal temperature protecting against the cold in winter and ensuring a comfortable room temperature in summer.  Furthermore, low moisture retention and fast drying elements also help to optimise thermal protection.  Therefore, using Porotherm will help to cut heating bills as the blocks store solar energy for gradual release when needed, making it one of the most energy efficient materials available as well.
