Pitfalls of sprayable insulation

New heaters are gaining popularity in the construction industry, which are applied to the surface using spray foam. Those who want to make their homes warmer are impressed by the convenient foam application process, low labor and time costs. Indeed, the new product with the proper skill significantly exceeds the obsolete heat-insulating materials that were used by our parents. But there are pitfalls that can ruin the whole impression of the new technology. It is important to study the features of the sprayer in advance in order to avoid common mistakes and not to start work from scratch.

Problem 1: the foam is applied too thin

Before embarking on heat-insulating work, you need to understand that foam happens with closed and open porosity. Both provide thermal insulation and air tightness. At the same time, you need to know that the two types of foam have a different coefficient of resistance to heat transfer. This means that foam with open porosity is more likely to fill all niches and voids. Of course, if during the installation a sufficient amount of material was used. Foam with closed porosity may not be able to cope with this task, therefore it is important to check the quality of work performed in several places on the surface upon completion. Coverage should be uniform.

Problem 2: Air leak through missing areas

If the foam is not evenly distributed on the surface, uninsulated areas may form. Humid air entering the room and meeting with cold surfaces forms condensate. This is fraught with constant dampness and drops flowing down from the ventilation grilles. Full sealing of the building envelope is a prerequisite for high-quality thermal insulation.

Problem 3: shrinkage and flaking foam

The cause of such problems can be poor-quality material, so it is important to buy foam in specialized stores. Non-compliance with the technological process when mixing the components can also lead to such troubles. In addition, the insulation is exposed to ultraviolet radiation, so it is advisable to color it after drying.

In many respects, the energy efficiency of the house and other buildings depends on the skill of specialists and the quality of the selected material. If you perform the work according to the rules, you can achieve high-quality and durable thermal insulation
