It also restricts the use of the living or utility space. The other hand, is exposed to various stresses and can lead to the formation of mould if not installed properly. Exterior, interior and core insulationĪmong the various options for insulating buildings, exterior insulation is the easiest and least problematic from a structural perspective. protection against overheating in the summer months, fire protection and even permeability to water vapour. In addition to heat conductivity, other properties play a role in the selection of a particular insulation material, e. Mineral wool and polystyrene have a heat conductivity of approx. K)) for PUR insulation materials up to 0.045 W/(m.In insulation materials, the range extends from approx. The ability of an insulation material to transfer heat is specified by its thermal conductivity: excellent insulation is obtained from materials with low thermal conductivity. Those based on wood fibre, hemp or seaweed. Organic insulation materials can be broken down further into fossil-based insulation materials, such as polystyrene, and renewable insulation materials, such as Examples of inorganic insulation materials are mineral wool or ex - pand ed granules. Insulation materials are mainly distinguished between organic and inorganic insulation materials. The insulation levels can be classified as exterior, interior and core insulation. Insulation options can be differentiated according to various insulation levels and insulation materials. Germany has been investing in energy-efficient building and renovation for many years and has therefore acquired considerable experience in this area It is therefore also beneficial in hot regions. An effective envelope protects the building from cold in the winter and from heat in the summer. In addition to reducing energy costs and CO2 emissions, optimising the building envelope also enhances indoor comfort and increases the value of the property. Key considerations in all cases are an individual evaluation of the entire building and skilled, professional planning and realisation. Important factors in the refurbishment of the building envelope are the insulating material, the avoidance of thermal bridging, windows and glass constructions and a high degree of air-tightness overall. Older houses in particular consume up to five times more energy than new builds, with the largest share of heat being lost through their external surfaces (see German Energy Agency, in German). This is an important cost factor for companies and private individuals alike. In Germany, heating and hot water requirements alone account for approximately 35 percent of total final energy consumption (see German Energy Agency, in German).
