Find out more about how we approach this building scenario. Generally, flat roof constructions using wood fibre insulation can be constructed without any ventilation so long as an intelligent vapour control membrane is fitted to the interior. This type of…
Find out more about how we approach this building scenario. We often get asked why our renders are lime and not cement based. People query why breathability matters if you’re rendering on to impervious materials and why you’d pay more for no…
Find out more about how we approach this building scenario. The way things used to be Prior to setting up Back to Earth as a material supply company we had Back to Earth the building restoration company. During those years…
Find out more about how we approach this building scenario. The U-value of a building element, such as a wall, roof or floor, is a measure of the thermal transmittance of that element. The lower the U-value, the slower the…
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…
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 a vapour control layer? In simple terms, this is a…
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…
