Warming up the house is a prerequisite for maintaining the thermal comfort of the inhabitants in winter, and in principle it is a question of achieving this at a reasonable cost. Nothing stands in the way of a non-insulated house heating very intensively and accepting very large heat losses, and thus large expenses from the household budget. However, every heat calorie is a real cost for the owner of the house and for the natural environment, because it is usually associated with the need to burn some fuel, and this means releasing carbon dioxide and other harmful gases into the atmosphere. Thanks to an effective insulation system of the house it is possible to reduce the loss of heat energy and thus reduce the demand for it. During frosts, it is usually necessary to heat the house all the time, but if the insulation is effective enough, at positive temperatures it turns out to be unnecessary. This is a huge benefit for the household budget and the environment, and in addition, the house gains limited resistance to UV radiation, extreme weather conditions and mechanical damage.
In order to enjoy all these benefits, it is necessary to choose the right material to insulate the house and create a fully professional insulation system. This should always be handled by a specialist.
The material worth considering is spray polyurethane PUR foams with excellent insulation properties. This is one of the best ways to significantly improve the energy efficiency of the structure. Improvement in this field is possible thanks to the fact that polyurethane foams are applied directly to the insulated surface by spraying methods. Such methods make it possible to create a uniform layer with no gaps, binders or heat bridges. Elimination of these typical disadvantages of other technologies makes it possible to limit heat losses to a maximum extent, while maintaining a relatively small thickness of insulation. Instead of 20 cm thick foamed polystyrene, polyurethane foam with a layer of 10 cm is sufficient. There are also no problems with covering any surface. Low absorbency surfaces require easy priming, but in most cases the excellent adhesive properties of the foam allow it to be applied to the surface without prior preparation. It should also be emphasized that polyurethane PUR foams are very durable and the effectiveness of the insulation does not decrease with time.
