Insulation of external walls – why is it worth it?

Many single-family home owners are afraid of the amounts associated with heating costs each winter. Autumn plush and winter, especially the harsh one can heavily burden the household budget with the costs of heating the house. How to make these amounts much lower without lowering the temperature inside the house?

Insulation of external walls turns out to be an excellent solution, which means that the heat stays in the building for a much longer time, which in turn means that the costs of maintaining heat are falling. Anyone who has invested in the insulation of external walls after a fairly short period of time can see that the bills in the heating season are much lower than before the insulation of the external walls was made. In the end, the costs incurred by us during the thermal insulation of the building very quickly pay off more. After insulation of external walls, heating bills can be reduced by as much as 15%, which is a really impressive result. Many people mistakenly assume that heat escapes through the windows and doors of the house, but the truth is different, heat loss occurs through the insulated walls of the building, and insulation of external walls helps to deal with this problem once and for all.

Choosing materials for external wall insulation

If we decide to make external wall insulation in our home, we should make a decision regarding the service contractor and the materials we want to use during the insulation process. Styrofoam and mineral wool are still the most frequently chosen materials for external wall insulation, if we are not completely convinced which material will be the best for our property, then we should definitely get the advice of professionals who will provide us with detailed information and professional advice. There are many differences between mineral wool and styrofoam, one of them is the lead time, with mineral wool it takes a bit longer, the price is also slightly higher. Does this mean that foam is cheaper means it is worse? Definitely not! Both of these materials are very popular due to their effectiveness in insulating external walls.

Styrofoam and its many advantages

Styrofoam, as is commonly known, consists of balls that are filled with air and it is this air that makes this material an excellent insulator. However, styrofoam also has other advantages such as the fact that it does not soak up with water, is lightweight, and at the same time extremely durable, so we are sure that our insulation of external walls will be durable and will not require frequent repairs. Each of us also cares that the material that will be part of our home be completely safe, and that styrofoam also meets this criterion. This material does not have any harmful substances, it is resistant to mold, fungi and bacteria, which will certainly please anyone who has had the trouble of struggling with moisture in their home. The fast deadline and low price are only a complement to many advantages of insulating your home with foam.

Mineral wool – why is it worth it?

Mineral wool is a natural product that arises from the melting of mineral rocks, after which it is subjected to appropriate treatment to turn into excellent quality material for insulation of external walls. The great advantage of mineral wool is the fact that it is very durable and vapor-permeable, and at the same time resistant to any chemical substances. Mineral wool is also an extremely safe material that is completely non-flammable and also resistant to moisture. Due to its non-flammability, mineral wool is often chosen for insulation of external walls in company buildings. This material also has an additional advantage that lovers of peaceful relaxation at home will appreciate. What is the advantage? Mineral wool perfectly reduces noise from outside the building.

Regardless of whether we choose styrofoam or decide to use mineral wool, our insulation of external walls will not only be effective and durable, but also made of safe, proven materials.
