Polyurethane foam allows you to quickly fill the space between the wall opening and the new container or frame, in case of installation of windows. This is a fast-curing hermetic substance that prevents the formation of cracks and promotes the fixation of building elements in the structure. But the foam has one drawback - it is inaccurately dispensed directly from the cylinder, so for a economical and aesthetic use they acquire a special gun. In the case of home repairs, you should use an inexpensive model, and for regular work you need a professional pistol. The article details these and other features of the best models of such equipment. This will help you choose a tool that is convenient for you and suitable for performing the planned work.

A great role is played by a good mounting system of the cylinder. These are the main features of professional inventory. Begins the cost of such a tool from 800 rubles. Below are the best guns for mounting foam according to those who have tried them in action.
Kraftool All-Metal - Reliability and Functionality
The first model has very practical care features. One of the most common problems with such an inventory is the clogging of the supply tube. In the "Metal" model provides for the removal of the nose from the main body by twisting the nut. This allows you to quickly access for through clearance cleaning.
The cylinder mount is made of brass, which increases the number of fixings for consumable items. If you hold the gun and the cylinder assembly, upside down (putting the structure on the table), then nothing leaks. Copper alloy casing provides strength when performing manipulations and protects during a fall.But because of this, the instrument has more weight than its counterparts, which overloads the arm.
Advantages:
- removable spout;
- very long service life (up to 7 years);
- copper alloy casing;
- tight;
- Remover kit for cleaning;
- reliable fastening under the balloon.
Disadvantages:
- heavier than analogues;
- high price;
- When hitting the rear tensioner, foam may seep from the spout.
Matrix 88669 - clean and reliable
This model is distinguished by its teflon-coated body. Special spraying, akin to a non-stick coating in pans, does not allow foam residues to adhere tightly both in the supply tube and on the cylinder fixing element.
After use, just wipe the tool outside and clean the spout with a special nozzle. But this requires careful action, as Teflon is easily scratched and careless handling will ruin expensive inventory.
The trigger of the pistol is quite smooth, which can cause a finger to slide off. All elements are made of a metal alloy "TsAM", which makes the design durable and reliable. The handle has two stops to prevent fingers from pinching by the trigger and “heel” of the regulator.

- reliable copper alloy casing;
- thin nose;
- quick feed setting.
Disadvantages:
- scratched teflon coating;
- overpriced;
- smooth trigger;
- requires a separate storage case.
Hilti cf-ds1 - a true professional
This is one of the best tools for professional use. It looks like a real gun, because it has a more dense body with a three-dimensional design. The trigger has an additional slider that blocks its involuntary pressing. This will protect against foam in the belt or in the trunk of the car.
Thanks to a thin spout, at the end of which there is no nut, it is easy to push the tip into hard-to-reach places and feed foam there. A well-thought-out hermetic system allows blowing in the lateral position without “snorting” the balloon. The tool body is made of reinforced plastic and does not disassemble. Cleaning is carried out only outside and passing through the trunk with a special nozzle.
Advantages:
- very light weight;
- random lock block slider;
- the handle is convenient for a large hand;

The needle diameter is significantly expanded than that of analogs, and is 4 mm, so wide gaps can be repaired in a single pass. But you can set and economical flow, where one cylinder (750 g) is enough for five windows.
The handle is ergonomic, but not very suitable for a large hand. But it is covered with non-dissolving nylon. Weight 600 g allows you to work all day. Threaded connections provide complete disassembly of the structure for cleaning.
Teflon coating does not strongly adhere to the foam body. Building accessory can serve for a long time. Rubber seals on the valves tolerate solvent treatment well and do not decompose.

- expansion compartment;
- teflon;
- increased needle diameter;
- fully collapsible;
- narrowed nose;
- all elements are metallic;

The best amateur guns for mounting foam
If you need to perform one-off work on the installation of a number of windows or several doors, it is advisable to purchase an inexpensive gun for mounting foam.But the desire to save should not prevent you from doing all the work until the end, so the following are a brief description of the best amateur pistols that have the greatest number of positive reviews.
Stayer Econom - an indestructible tool
This German representative of construction equipment is distinguished by its endurance. For this, it has a stainless supply tube that is easy to clean and not scratch. Unfortunately, it is not removed by unscrewing the union nut, but requires flushing. For fixing the cylinder meets aluminum grip with a full thread. The trigger is also made of metal.
After applying the foam and the end of the work, the barrel must be cleaned with a cleaning agent. If this is not done, the permeability may be blocked. The delivery system has a ball valve at the inlet and a needle mechanism at the outlet. They work flawlessly and securely hold the mixture.
Advantages:
- affordable price;
- aluminium case;
- practical foam control;
- handy in hand;
- reliable valve.
Disadvantages:
- mount does not fit all cylinders;
- very clumsy design;
- not collapsible design;
- If you leave the bottle in the gun for a few weeks, the foam in the nozzle may harden.
Atoll G-116 - the most affordable
Among the guns for the foam, this copy is the most affordable in its price range. Construction equipment has a wide edge in the place of fixation of the cylinder, which allows you to quickly change it and securely hold during operation. A full thread is not erased for a long time, and it helps to use it in several repairs, provided it is properly cleaned.
The tool is very easy and convenient for long work. But the handle has only a limiter against contact with the “penny”, for the occasional failure of the foam setting. There is no such limiter before the trigger, and you can easily pin down your fingers.
Advantages:
- cheap;
- it is convenient to change cylinders;
- aluminium case;
- light;
- not whimsical to maintain.
Disadvantages:
- flushing quickly corrodes the rubber rings on the valves;
- there is no stopper before the trigger on the handle;

The gun is the lightest in its class. The handle is voluminous and conveniently holds with a big hand. The needle valve holds the foam securely.
Adjustment of supply is carried out by turn of the bent lever. To lock the feed, it turns into a special groove. If the gun falls and hits this lever on the ground, a lot of foam will come out. Clean immediately after use. Foam is poorly separated from plastic. Cylinders change quickly and easily thanks to a wide retainer, but its plastic construction severely limits the life of the gun.
Advantages:
- very cheap;
- convenient for large hands;
- light;
- wide limiters;
- steel tube spout.
Disadvantages:
- weak cylinder retainer;
- plastic trigger;
- primitive feed adjustment;
- breaks easily when dropped.
P.I.T. - all for one repair
Another Asian representative is this model. All the elements in it are also plastic, but the barrel and the valve are metal. The clamp to the cylinder, though wide, but the threads of the thread quickly lick. The foam quantity regulator has a classic wheel shape and allows you to adjust the tool to a thin feed.
The long barrel helps to climb into tight places during installation. This contributes to the narrowed part, which accounts for 30% of the total length. The three-finger trigger is convenient for small hands.
Advantages:
- fine feed adjustment;
- economical consumption;
- narrowed nose;
- light;
- many tips included;
- barrel 190 mm.
Disadvantages:
- when stored with a balloon, it requires the release of foam once a week to preserve patency;
- all items are plastic.
Which gun for foam to buy
Since the cost of this tool for sealing gaps varies from several hundred to several thousand rubles, it is worth clearly determining how much and the type of work to be performed. This will be a key factor in determining the appropriate model.
Tasks can be divided into the following categories:
1. For continuous professional activity, where you need to install windows and doors, seal the sills and hatches, you should invest in reliable guns Hilti cf-ds1 or Auster Matequs. They will work for many years and flawlessly.
2. If you need to make a one-time repair, where you need to squeeze out a few cylinders, then pay for the inexpensive model that allows you to apply foam more accurately. It can be Blast extra light or Atoll G-116.
3. In the case of a single, but large in scope project installation work, it is better to pay attention to the economical P.I.T. pistol. They can fill a large number of seams without excessive foam, and save on the tool itself.
4. If there is a difficult task ahead, where the gap between the barrel and the opening is minimal, a trunk of sufficient length and with a narrow spout will be required. A good option would be Matequs Super Teflon or Matrix 88669.
