In the course of construction work, when installing window and door blocks, erecting partitions, laying communications, it becomes necessary to hermetically fill gaps and fix structural elements.
For this, polyurethane foam is used with high adhesion to any surface and good thermal insulation properties. Consider how to choose the best gun for working with polyurethane foam. Without a special device, it is impossible to carefully fill narrow gaps with sticky foam material; the excess material that has come out has to be cut off after solidification. This leads to a significant waste of material, which is especially critical for large volumes of work.
A gun is a mechanical device that delivers mounting foam through a thin nozzle. Its use saves material and helps to foam even narrow gaps with high quality. Manufacturers offer models for professional and domestic use, which vary in durability and price.

Since the design of the gun for supplying mounting foam is quite simple, its quality depends on the version of only a few details:
- Cylinder retainer (adapter). The thread of the latch, made of plastic or low-quality silumin, is erased during prolonged use.
- Working valve. Durable valves are available in stainless steel or bronze. With insufficient strength of the metal, the element is deformed - an increase in the contact patch between the seat and the needle increases the risk of leakage.
- check valve. If the reliability of this part is insufficient, when the cylinder is removed, the foam from the gun comes out and must be removed immediately. At the same time, air enters the tube through the valve, which leads to rapid polymerization of the remaining foam inside the instrument.
- tube mount. If the part is pressed into the body, the gun is more difficult to clean after use. Threaded connection is more practical. To remove the handset, use a ring or open-end wrench.

The durability of the product depends on the material of manufacture of the case. Manufacturers use different types of alloys, plastic, a combination of plastic with metal. The more plastic, the lighter and cheaper the tool. Such models are suitable for use during home repairs. The exception is a professional tool made of impact-resistant plastic and stainless steel.
A metal gun for working with polyurethane foam is noticeably heavier than a plastic one. For the manufacture of the tool body, aluminum, brass can be used, but most often it is one of the alloys:
- Zinc-aluminum-copper spav (ZAM). Comparable in strength to mild steel. Models made of this material have the greatest weight and are designed for a long service life.
- Silumin. The alloy of aluminum with silicon is significantly inferior to TsAM in terms of strength. The reliability of a silumin case depends on the integrity of a particular manufacturer. Such a tool is noticeably lighter than models from TsAM
When choosing a tool, pay attention to the ease of cleaning it. Expensive models often use a Teflon coating. Remains of polyurethane foam are easily removed from it, even if it has had time to harden. But Teflon is easily damaged, so you need to be careful when cleaning - in places where the coating is torn off, the foamed polyurethane will stick tightly.
Due to the smooth surface, the polished stainless steel tube is also easy to clean. If the feed tube is made of plastic, the gun must be flushed immediately after work, since later it will not be possible to fully clean the channel. For cleaning it is necessary to use special tools.
