Trade association: https://fved.net In Germany, around 20 million walls, roofs and floors could be efficiently insulated using blown-in or blown-on insulation, whereby this method is not only the fastest but also the most cost-effective, with costs often under 5,000 euros per measure. This usually pays for itself after just three to ten years. Arnold Drewer, an expert in this field, explains the procedure: A specialist company opens the component, puts a hose on it and fills it with the appropriate insulation material - a process that is completed in just a few hours. This is particularly relevant for double-shell masonry, which is present in 30% of buildings in Germany. Blown-in insulation prevents heat loss and possible structural damage that could occur due to uninsulated hollow layers. Likewise, around 75% of German single-family homes have wooden beam ceilings, which can be insulated easily and without a lot of cleanup. Blow-in insulation is also suitable for special cases such as flat roofs, wooden floors above basements and crawl spaces. It is important that only approved products are used that are moisture-resistant and non-flammable. To implement this, it is advisable to contact an experienced specialist company.
