Growing environmental awareness and rising energy prices lead to more and more years since energy saving measures. Alterations in the house but want to be well thought out. The key issue for building owners: Which insulation is right for me?
Should there be a façade insulation, interior insulation, or even a cavity insulation? Different ways with different materials can arise fundamental questions. Ralf Holt, experts from the Association for Healthy Biolysa: "When external insulation is applied to the insulation on the outside wall. thermal bridges can be best avoided by this type of insulation. "As is known, however, can not absorb all the houses outside. Is the listed building, the facade must often remain preserved. Then there is the possibility to opt either for an internal insulation or an insulation cavity.
An interior insulation is a building physical challenge is building consultants Holt argued. Because the goal of inner insulation was not the only improvement of the U-value (heat transfer coefficient, formerly known as K-value). It would rather the overall design, including relevant variables such as the thermal conductivity and the water vapor permeability are taken into account to achieve optimal improvement of the U-value. Holt, "An interior insulation should be planned by a specialist, ie a energy consultants, architects, engineers or building physicist and then executed appropriately."
A third possibility is the subsequent cavity insulation. This method is introduced into the hollow layer of a cavity wall, insulation work. In this method, the building consultant from Biolysa was to ensure that sufficient void is available. Regarding the critical analysis were chosen permeable insulation. "Strong uncertainty," Holt said Ralf, "there is in choosing the right insulation material. By skilful manipulation in advertising are always offered new materials "When choosing the right material recommended by the building consultants to consider fundamental criteria. An insulation should in addition to good thermal insulation effect to be diffusible. In addition, the fire was observed.
"With the shield against wind and cold, the houses are more dense. Building biological aspects in this context are more interesting and should be followed. Due to the lack of air in the buildings remain toxic substances from wallpaper, furniture, paints and carpets much longer in the air, "adds the building biologist from Sassenberg.
