7 best mounting foams

When performing a number of construction and repair works, such universal material is used for sealing as polyurethane foam. The product is a one-component polyurethane composition, which is under pressure in a cylinder. When exposed to air, the composition polymerizes and hardens, forming a dense porous insulation layer. The material has good sound and heat insulation qualities, moisture resistance, low electrical conductivity and resistance to fire. The weak sides of the mounting foam are sensitivity to ultraviolet rays, due to which the sealant turns yellow and collapses. In the trading network there is a huge range of mounting foams. To make it easier for the buyer to choose the optimal composition for the price and properties, experts recommend to take into account a few points.

Main criteria for selection of foam

1. Ordinary 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 the gaps and voids, where special care and accuracy in work are not required.
2. For professionals designed mounting foam in cylinders under a special gun. The material has a high density, after drying, it retains the original volume, the foam yield is much higher. Thanks to the gun, you can adjust the flow of the insulator, which saves the product. One balloon can be used several times, washing the gun after each use.
3. An important characteristic of the foam becomes the temperature range of application. Having bought summer composition, it is possible to work at a positive temperature from +5 to + 40 ° С. All-season product has a wider operating range of -10 ... + 30 ° C. And to seal the seams and fill the voids in the cold, it is better to use the winter variant, which can withstand temperatures up to -20 ° C.
4. On the spray can with foam can be found and fire markings. If the product is labeled B1, then the composition is different refractory qualities. The designation B3 indicates the flammability of the material. This factor is important to consider when sealing chimneys or heating boilers.

The experts selected 7 best mounting foams for our review. The following criteria were taken into account when compiling the rating:

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

Penosil GoldGun 65

Rating: 4.9

Penosil GoldGun 65 foam is mainly chosen by professional builders. They mark the perfect combination of price and quality of the Estonian product. Experts also note a lack of shrinkage and a slight re-expansion, which makes the composition predictable. Special praise from the specialists of the foam earned for the highest possible output. The material finds a wide range of applications, starting with the installation of window and door frames and ending with the filling of various voids.

According to experts, Penosil GoldGun 65 assembly foam deserves the highest line of the rating for high quality, reasonable price, consistently white color and record volume output. You can criticize the foam only for fear of low temperatures.

Soudal

Rating: 4.8

The Belgian Soudal polyurethane foam does not yield to the winner of the quality rating. It differs in fire resistance, which allows the composition to be used for sealing furnaces or chimneys, creating a thermal envelope or when roofing. The isolator shows excellent adhesion, no shrinkage and minimal secondary expansion. After drying, the product becomes dense, it has a finely porous structure. Experts note such qualities of foam as a good output volume, durability of insulation, color retention, and absence of cracks.

Along with good quality, a wide scope of application and preservation of volume after drying, there is a material and disadvantages. The main one is the professional builders consider the accelerated destruction of insulation under the influence of sunlight.

Makroflex Standart

Rating: 4.8

One of the most popular installation foams in our country is the Estonian product Makroflex Standart. It is used by home craftsmen and professional builders. A distinctive feature of the foam is excellent adhesion to any base. Due to its versatility, the insulator is used in various types of work, whether it is foaming gaps or installing windows and doors. The material is well resistant to temperature fluctuations, so that when cooling is not necessary to run with a balloon to the heat source.

The promotion of the brand played a cruel joke with him. In the domestic market there is an abundance of fakes with the inscription Makroflex. Their appearance contributed to the high price for a quality product. Experts put the foam on the third position of the rating also for shrinkage after drying.

Titan o2

Rating: 4.7

The best option for winter use would be the Polish Titan O2 foam. The product is notable for its affordability, and experts confirm its high quality. But to get into the top three of the foam did not allow consumer reviews. 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 solidification, a finely dense dense structure is formed, which does not change its volume. Foam can be used in children's or medical institutions due to its harmlessness to the human body.

Professionals often buy Titan O2 foam for installing windows and doors in new buildings. Over the years, the insulation remains airtight and intact.

Ultima

Rating: 4.6

The Ultima polyurethane foam boasts the most affordable price. It is designed for domestic use, it can be used to seal cracks and voids inside and outside buildings. The product has good adhesion and fast polymerization. Included with the balloon is a convenient applicator with which you can fill any cavities. Experts included foam in the rating due to ease of use, the formation of a dense layer of insulation. Rise above the assembly foam did not allow the secondary expansion of 70%.The insulation layer must be reliably protected from UV light.

Users have identified a large volume, low price and ease of use from positive properties. At the same time, there is a high consumption of material and a persistent unpleasant odor.

TechnoNIKOL 65 Constant

Rating: 4.5

Worthy competition to foreign materials is domestic installation foam TechnoNIKOL 65 Constant. Experts call its strengths versatility, increased insulator output from the cylinder, moderate expansion. When fully dried, no shrinkage is observed, the secondary expansion is within the limits of error. The product is not inferior to the leaders in the adhesiveness of various building materials. Most often, the mounting foam is used to isolate plumbing, installation of door and window blocks.

Consumers in the reviews complain about the lack of domestic insulation material in the distribution network. Do not use foam with bases such as polyethylene, fluoroplastic or silicone.

Moment Installation

Rating: 4.5

In every Russian store with a construction bias you can find one-component foam Moment Installation. Cylinders with insulating material are available as a gun, and disposable. All-season foam, which is suitable for a wide range of construction and repair works, is in the greatest demand. The composition is not inferior to the leaders of the rating in adhesion, after drying a dense and uniform insulation layer is formed. Environmentalists have not found compounds toxic or harmful to the human body in the material.

Low position in our rating of foam Moment Installation can be explained by a large number of fakes. Some of them have a pungent odor and not a characteristic yellow color. Another counterfeit is able to squeeze out a door or window case during the drying process.
