Because we supply quite a range of different wood fibre boards, we often get asked to recommend the best insulation for many different types of walling, whether it is soft sandstone, hard flint or old brick.
Last month we wrote an article about decrement delay and how it can help enormously with keeping buildings comfortable, particularly during heat waves such as the one we’ve recently experienced in the UK.
To further highlight and explain this we’ve collected the below data from a Passivhaus building which uses wood fibre insulation in the roof and walls, along with lots of clay boards lining the interior to boost thermal mass.
We regularly get asked whether it is possible to mix wood fibre insulation with synthetic insulation, to save on cost and give a lower U-value for a given thickness but to try and retain some of the benefits of wood fibre.
We often get asked what is the best thickness of insulation to use when considering solid wall insulation and also whether internal or external insulation is best.
EPD’s are a uniform way to evidence the environmental impacts of manufacturing and using a product through a Life Cycle Analysis or LCA. This enables us to assess the embodied carbon associated with any particular construction, make comparisons between materials and therefore reduce the environmental impact of construction.
