Find out more about how we approach this building scenario. Psi values (pronounced p’see) are a measurement of the heat loss that occurs at all junctions where non-repeating thermal bridges occur. These can be wall to wall junctions, wall to…
Find out more about how we approach this building scenario. Clay plasters are often associated with more ‘way-out’ construction or very niche historic building restoration. However, there are several properties of the material that makes it much more useful in…
Find out more about how we approach this building scenario. Over the last few months, the Back to Earth team have been busy developing the first freely accessible, online wood fibre insulation course. Designed for architects, builders and self-builders, the thirteen…
Find out more about how we approach this building scenario. Here we look at what a Vapour Control Layer is, how a Vapour Control Layer (VCL) works, the types of VCLs available and if vapour check plasterboard is a viable alternative. What is…
Find out more about how we approach this building scenario. Cavity wall insulation’s a topic that I get asked an awful lot about and come across a lot of situations where it’s used either inappropriately or it isn’t used when…
Find out more about how we approach this building scenario. In many Victorian houses a suspended timber floor was formed as the ground floor of the house. This was often built over bare earth and relies on good ventilation to…
Find out more about how we approach this building scenario. One of the many reasons that we at Back to Earth focus on insulation so much is that it is the single material which has the most influence over the performance,…
Find out more about how we approach this building scenario. You only need to use EPS on the lower 300mm of the wall externally or if the external ground level is higher than the internal. If the ground level externally…
Find out more about the passive house standard of building. There are so many benefits to Passivhaus, financial, physiological and psychological. Financially, although the build cost can be slightly higher, the running costs are so much lower that you really…
Find out more about the passive house standard of building. As a good guide I would say between 10% and 20% more, depending on the type, size and quality of the building. The bigger the building and the higher the…
