Today, great demands are being placed on the energy efficiency of homes. This is not only an ecological issue, but primarily a question of the money we spend per year. It is not a pointless decision for many homeowners to insulate their facades. There are several options. [The most common way is to insulate from the outside of the house, but you may live in or not own a historic building, for example. However, here we will talk about insulating the outside of the house.
One of the most common and effective options is the use of polystyrene foam . This is a very versatile material that many builders choose to use not only because of its ease of installation, but also because of its cost effectiveness. Polystyrene foam has also, over time, debunked the myth that it is not breathable, and now even houses with thick insulation no longer have to worry about excess condensation. The insulation is simply glued to the house facade and secured with plastic dowels for additional adhesion. Polystyrene is used in both new and old houses. The finished insulation is then covered with stucco so that the house looks exactly as desired and saves energy.
Another more common option is the use of so-called mineral wool, or stone fiber wool. This is a material with excellent thermal insulation properties and at the same time perfect vapor permeability. It is not only fire resistant, but also has excellent sound insulation properties. Unlike polystyrene, the installation of mineral wool insulation is relatively labor intensive, which is reflected in the final price. In addition, this method can easily be applied to older buildings as well as newer homes.
However, the decision should be left purely to the owner, who has the opportunity to reach out to experts and consult with them on the best solution. In some cases, it may not be worthwhile at all to do the insulation work on one\’s own.
