The importance of thermal insulation
If you want to reduce heating costs, which account for up to 60% of energy costs in your overhead costs, install or increase the thickness of thermal insulation and replace windows. This especially applies to family houses without a facade and those that were built without thermal insulation. Thermal insulation not only reduces losses in the winter, but also ensures that your house does not overheat in the summer. In this way, it is possible to almost completely avoid the installation of air conditioners, or their capacity and energy consumption will be significantly lower than for a non-insulated house.
How much energy consumption can be reduced by thermal insulation?
Energy consumption for heating and cooling can be significantly reduced by full thermal insulation of the peripheral construction parts of buildings (walls, floors, roofs), and that in old dilapidated houses up to 6 times. The most preferred material for insulation is stone wool, followed by Styrofoam. In addition to the fact that thermal insulation significantly contributes to saving the energy required for heating, it also protects the building element from overheating, prevents the condensation of water vapor (which leads to the rotting of the building material and the creation of microorganisms, fungi and mold) and contributes to the thermal comfort in the room (because they are Thermal insulation enables the accumulation of heat in the walls of the rooms, i.e. their heating, thus reducing the temperature difference between the internal surfaces and the air in the rooms.
Thermal insulation of the outer wall
Thermal insulation of the external wall is done by adding a new layer of thermal insulation, most often from the outside of the wall, much less often from the inside. Insulation from the inside of the wall is used in buildings under protection to prevent external changes to the appearance of the building. The rules for the insulation of the building from the inside of the wall are stricter due to the need to solve the problem of moisture condensation, preventing the appearance of mold, stricter fire protection standards, the useful space is reduced. All these reasons make this type of insulation significantly more expensive, so in most cases, the insulation of the external walls is used from the outside.
Materials for thermal insulation
Heat isolation Styrofoam is a good insulating material with a good coefficient of thermal conductivity, it is cheap and the installation process itself is simple, so it is one of the most popular materials used for insulation today. It has weaker fire-fighting effects than stone or mineral wool and is not resistant to temperatures above 80 °C. Mineral wool, usually rock wool, is a good thermal insulator with a high coefficient of thermal conductivity, which ranks it among the best thermal insulation materials. Mineral wool is also used for sound and fire insulation due to its properties. It is resistant to aging and decay, as well as to microorganisms and insects. It is used in all exterior constructions, and is not recommended for insulating basement walls underground.
Heat energy losses on windows
When all the losses arising from the windows are taken into account, it comes to the fact that the losses from the windows in some buildings can amount to 50% of all the losses of the building. The losses on the windows are specifically more than 10 times higher than the losses on the walls, so you can see the importance they play in the overall energy needs of the building. Old buildings and houses use windows that have a high coefficient of thermal conductivity, so the losses in such windows are high. It is recommended to use windows that have a lower thermal conductivity coefficient, which reduces losses. The glass and the window profile contribute to the total losses on the window. Today”s glasses are produced in a two-layer or three-layer vacuum variant or the interspace is filled with different gases (carbon dioxide, argon), which enable better thermal insulation properties. The window profile should ensure good sealing when closing, breaking the thermal bridge in the profile, easy opening and a low coefficient of heat conduction.
Should you contact experts for thermal insulation?
Definitely, yes. Good thermal insulation can significantly increase your home budget, and for this reason it pays to hire experts who will suggest the best solution based on their experience and calculations. The investment will pay off in a few years. If you do not have good thermal insulation in your building, we suggest that you register at Bellcom.rs and post the required service in order to receive offers from professionals.
