7 best polyurethane foams

Review of the best according to the editorial board. On the selection criteria. This material is subjective and does not constitute advertising and does not serve as a purchase guide. Before buying, you need to consult with a specialist.

When performing a number of construction and repair work, such a versatile sealing material as polyurethane foam is used. The product is a one-component polyurethane compound that is pressurized in a can. When exposed to air, the composition polymerizes and hardens, forming a dense porous layer of insulation. The material has good sound and heat insulation properties, moisture resistance, low electrical conductivity and fire resistance. The weaknesses of polyurethane foam are sensitivity to ultraviolet rays, due to which the sealant turns yellow and collapses. There is a huge assortment of polyurethane foams in the trade network. To make it easier for the buyer to choose the optimal composition for price and properties, experts recommend taking into account several points.

The main criteria for choosing a polyurethane foam

1. Regular household foam is available in a disposable version, with a tube attached to the cylinder. Usually such a product does not have a high density, it has a noticeable secondary expansion. Most often, such a composition is purchased to fill gaps and voids, where special accuracy and precision in work is not required.
2. For professionals, polyurethane foam in cylinders for a special gun is intended. The material has a high density, after drying it retains its original volume, the foam yield is much higher. Thanks to the pistol, the flow of the insulator can be adjusted, which allows an economical use of the product. One bottle can be used several times, flushing the gun after each use.
3. An important characteristic of polyurethane foam is the temperature range of application. Having bought a summer composition, you can work at a positive temperature from +5 to + 40 ° C. The all-season product has a wider operating range of -10 … + 30 ° С. And to seal the seams and fill voids in frost, it is better to use the winter option, which can withstand temperatures down to -20 ° C.
4. You can also find fire protection markings on the spray foam can. If the product is marked B1, then the composition is refractory. The designation B3 indicates the flammability of the material. This factor is important to consider when sealing chimneys or heating boilers.

Experts have selected 7 of the best polyurethane foam for our review. When compiling the rating, the following criteria were taken into account:

1. safety of use and operation;
2. technical specifications;
3. price;
4. professional opinion;
5. reviews of domestic users.

Penosil GoldGun 65

Rating: 4.9

Penosil GoldGun 65 polyurethane foam is chosen mainly by professional builders. They mark the perfect combination of price and quality of the Estonian product. Experts also note that there is no shrinkage and little re-expansion, which makes the composition predictable. The foam deserves special praise from specialists for the highest possible yield. The material finds a wide range of applications, from the installation of window and door frames and ending with filling all kinds of voids.

According to experts, Penosil GoldGun 65 polyurethane foam deserves the top line of the rating for high quality, reasonable price, invariably white color and record volume yield. You can only criticize the foam for the fear of low temperatures.

Advantages

• high quality;

• acceptable price;

• record output in terms of volume;

• no shrinkage and secondary expansion;

disadvantages

• at sub-zero temperatures, foam does not come out of the container.

Soudal

Rating: 4.8

The Belgian polyurethane foam Soudal is not inferior to the winner of the rating in terms of quality. It is distinguished by its fire resistance, which makes it possible to use the composition for sealing furnaces or chimneys, creating a thermal sheath or when installing a roof. The insulator exhibits excellent adhesion, no shrinkage and minimal secondary expansion. After drying, the product becomes dense, it forms a fine-pored structure. Experts note such qualities of the foam as good yield, durability of insulation, color retention, and absence of cracks.

Along with good quality, wide scope and volume retention after drying, the material also has disadvantages. Professional builders consider the accelerated destruction of insulation under the influence of sunlight to be the main one.

Advantages

• wide scope;

• durability;

• dense fine-pored structure;

• heat and fire resistance;

disadvantages

• the destructive effects of UV rays.

Makroflex Standart

Rating: 4.8

One of the most popular polyurethane foams in our country is the Estonian product Makroflex Standart. It is used by both home craftsmen and professional builders. A distinctive feature of the foam is excellent adhesion to all substrates. Due to its versatility, the insulator is used for various types of work, whether it is foaming cracks or installing windows and doors. The material withstands temperature extremes well, so that during a cold snap you don't have to run with a can to the heat source.

The promotion of the brand played a cruel joke on him. There is an abundance of fakes with the Makroflex inscription on the domestic market. Their appearance was facilitated by the high price for a quality product. Experts put the foam in third place in the rating also for shrinkage after drying.

Advantages

• universality of application;

• resistance to temperature extremes;

• excellent adhesion ability;

disadvantages

• high price;

• shrinkage is observed after drying.

Titan o2

Rating: 4.7

The best option for winter use is the Polish Titan O2 foam. The product is notable for its affordability, its high quality is also confirmed by experts. But consumer reviews did not allow to get into the top three of the leaders. They note such negative qualities of the material as the fragility of existence outside buildings, low resistance to ultraviolet radiation. The rest of the insulator deserves the most flattering words. After hardening, a fine-celled dense structure is formed, which does not change its volume. The foam can be used in children's or medical institutions due to its harmlessness to the human body.

Professionals most often buy Titan O2 foam for the installation of windows and doors in new buildings. For many years, the insulation remains sealed and intact.

Advantages

• resistance to negative temperatures;

• no shrinkage;

• affordable price;

disadvantages

• collapses under the influence of external factors.

Ultima

Rating: 4.6

Ultima polyurethane foam can boast of the most affordable price. It is designed for domestic needs, with its help you can seal cracks and voids inside and outside buildings. The product has good adhesion and fast curing. The balloon comes with a handy applicator that can be used to fill any cavities. The experts included the foam in the rating due to its ease of use, the formation of a dense layer of insulation. The secondary expansion at the level of 70% did not allow to rise above the polyurethane foam. The insulation layer must be reliably protected from the influence of ultraviolet radiation.

Among the positive properties, users singled out large volume, low price and ease of use. At the same time, there is a high consumption of material and a persistent unpleasant odor.

Advantages

• low price;

• ease of use;

• fast drying;

disadvantages

• low resistance to atmospheric influences;

• high material consumption.
