Top ranking of the best polyurethane foams in 2020

In the process of repair and construction work, both beginners and professional repairmen and builders invariably deal with such a type of universal insulating material as polyurethane foam (another name for it is one-component foam).

This type of polyurethane sealant perfectly fills any cracks, voids and cavities, and also has such characteristics as heat and sound insulation, low electrical conductivity, moisture resistance, fire resistance. Cured polyurethane foam becomes hard, porous and light, but at the same time this substance is often very sensitive to ultraviolet light, therefore it turns yellow and collapses under the influence of sunlight.

Types of polyurethane foam

There are several types of this building composition differing in the principle of use and in relative temperature conditions under which repair work is carried out.

  1. Professional foam. Usually it is used with a special assembly gun. It differs in the density of the composition, and the secondary expansion of this sealant is almost absent. You should never use professional foam for minor home repairs, since its output from the cylinder is 3 times higher than household foam.
  2. Semi-professional. This is household foam that needs to be used in one go and does not require a gun as the can is fitted with a tube. The density of the composition is lower than that of professional foam, and the secondary expansion is greater, therefore, this composition is not suitable for serious work, such as installing windows, window sills and doors.
  3. Summer composition. They can work at temperatures from +5 to +35 degrees.
  4. Winter foam. Its composition differs from the summer one, the sealant can be used during severe frosts, as it can withstand temperatures down to -20 degrees.
  5. All-season. Combines the characteristics of winter and summer and can be used at temperatures from -10 to +30 degrees.
  6. Fireproof. On the cans you can see the marks - B1, B2, B3. These are the designations of the flammability of the material, where B1 is refractory, B2 is self-extinguishing, and B3 is a combustible substance. Of course, type B1 is preferable, which has a special fire-fighting composition and retains all its properties at high temperatures.

How to choose polyurethane foam?

When choosing a sealant, you should focus on several basic requirements for foam:

  • Elasticity. The higher the quality of the foam, the more elastic it is;
  • Shrinkage. In other words - the reduction of foam on drying, which should be minimal;
  • Structure. The composition should be thick and tenacious enough to adhere well to any surface and not drain;
  • Frost resistance. The solidified substance should not crumble and crack at low temperatures if construction and repair work is carried out outside the premises;
  • Porosity.The foam should not be too porous, otherwise the heat and sound insulation properties of the material decrease;
  • Expansion. During the release of the foam from the cylinder, as well as during its complete solidification, the expansion of the substance occurs, which should be minimal. Otherwise, excessive expansion of the foam can, for example, distort the door frame when installing doors;
  • Setting speed. The speed and productivity of work in general depends on this indicator.
  • Weight. A can of good quality, undiluted formulation should weigh approximately 910 grams.

Rating of mounting foams

There is a wide variety of types of sealants from different manufacturers, but there are actually not so many formulations that have firmly won positive reviews and popularity of users. Unfortunately, very often there are low-quality formulations that not only do not cope with their main responsibilities, but are also dangerous to health, since they contain harmful toxins. That is why it is very important to make the right choice, which guarantees high-quality repairs without harm to health.
