foam insulation

 The process of building foam insulation is constantly being improved and at the same time often accompanied by the use of the most effective and new technologies and more promising building materials than those that everyone is accustomed to. And now another type of high-quality insulation has appeared on the market, which is sprayed onto the surface of a specific area. This material has already occupied a leading position among the best heat insulators.

What is foam insulation?

Foam insulation performs a dual function: thermal insulation and sound insulation. It is a highly effective product for thermal and acoustic bridge insulation, both in small spaces and on large surfaces.

There are two main types of insulating foam: "spray insulating" foam and pump insulating foam.

We will see both methods in more detail: Aisinen-type insulating foam differs from polyurethane foam in a specific point: expanded or clogged polyurethane foam is much less ecological. However, both types of foam sound insulation are very effective and provide excellent results.

Capping, cap, seal, insulation: these are the characteristics of pump foam

Pump insulating foam is very effective in covering construction defects and in sealing thermal gaps: cracks, blind boxes, plumbing fixtures, etc. Don't let the winter cold pass through these cracks. Polyurethane pump insulation foam is a thermal and acoustic insulation that can be easily applied even in the smallest corners.

How is the insulating foam applied in the pump to achieve optimal thermal and acoustic insulation? You just have to fill in the space and wait for the foam to expand. Simple and effective! The application tube is placed in the aerosol valve and the walls or panels of the vacuum are moistened before insulation is added. Next, the foam pump is shaken for 1 minute, and half the volume of the space we want to isolate is filled with foam because the foam will expand. Let the foam dry for half an hour, remove the excess to level the board and leave it for 24 hours until it is completely absorbed.

Attention! Expanded or expanded foam is not suitable for some spaces, especially outdoor spaces, or where liquids and/or moisture are present. It is only suitable for use in sheltered and weather-protected locations.

Application

When foam insulation is sprayed, it coats the surface and hardens quickly. It dries quickly, provides relatively permanent insulation and will not sag. If the foam extends beyond the desired area, the excess insulation can be trimmed or trimmed to the desired size.

protection

Spray foam insulation is somewhat dangerous for people when spraying. Particles can be breathed into the eyes, skin, or through the mouth and nose if appropriate protective clothing and equipment are not worn. The chemicals can irritate the eyes and respiratory tract and cause swelling or a rash on the skin. The person is advised to wear goggles, a respirator, gloves, long sleeves, and long pants when spraying foam insulation.

Aside from cost and cleanliness, there are clear benefits to using spray foam insulation, which can penetrate small corners and crevices while providing better insulation. It can eliminate drafts and keep the building warm when it cools down. These features can help reduce a building's utility bill. By filling in cracks, foam insulation also helps prevent insects from entering the building.

Spray foam also adheres well to insulation surfaces, so it can adhere to walls from the inside or be laid on the underside of floors and insulated from below. Spray foam insulated homes often have a higher resale value than those using fiberglass insulation or other types of insulation. There are also environmental advantages; Notably, there are no fiberglass particles floating in the air. Also, the spray foam insulation does not itch when touched, and it prevents mold growth because it does not absorb water.

Foam insulation and use for private homes

In some cases, it is more profitable to use foam insulation, which has a number of advantages over conventional or bulk slab. Foam insulation has been used for a long time, has already gained a positive reputation, and has established itself as a popular building material with its own field of application. Foaming is widely used by building organizations for insulation, so why not use it in homes and private apartments.

How are foam insulation heaters used?

Liquid foam heaters are brewed directly into the insulated structure. A liquid foam is supplied from a cylinder or from a device that prepares a composition of components under pressure with a hose to the desired point. Subsequently, chemical reactions with the composition occur and, as a result, the foam hardens, forming a foamy homogeneous structure. The types of chemicals that occur in reactions depend on the type of insulation, and some use air and moisture on the body and in the air. Some insulation materials expand greatly during solidification, others can reduce in size ... Next, about the different types of these materials.

Advantages of foam insulation

Why is foam insulation used? They offer the following:

• Capable of creating a seamless continuous homogeneous layer, even around complex surfaces.

• It can be used in crevices, in narrow open cavities, where it can expand without breaking the material.

• Certain types can be used in closed cavities within structures - they expand slightly and contract upon solidification.

• Foam insulation can bind structures together, and has adhesive properties, which are used in construction.

• The materials are characterized by a high degree of thermal insulation, ie, these are effective insulation materials.

• When performing work, significant productivity is achieved, several times more than if plate material is laid.

The most important advantage in many cases is that it is not necessary to disassemble the structure for insulation, it is not necessary to completely level the surface, it is enough to remove spacers and dust, or they are used “as is”. They are used for any irregularities in fact.

What is the most widely used insulation foam

The following types of foam insulation materials are mainly used in the facilities.

• Polyurethane foam. It has a higher price, but at the same time it has great strength and better thermal insulation properties. It binds strongly to structures and significantly increases in volume when spraying. It has a high resistance to steam movement and hardly accumulates water. But it degrades from UV exposure, and requires sun protection. The formed surface of the insulating layer is very uneven - the average thickness is taken into account. Hazardous in the case of fire toxicity, but generally not equivalent to an environmental hazard. The widest application is found...

Polyurethane foam. Balloons with construction foam on the basis of polyurethane foam help builders - the seams and fastening are closed with this material. But it must be borne in mind that the resulting composition is not polyurethane foam at all, as such. Polyurethane foam is literally afraid of moisture, it crumbles from it. Also UV rays. It is not recommended to close the layers of insulation in private homes, and fasten them with polyurethane foam, since dew can destroy the material over time. But it is widely used in closed narrow gaps, along the perimeter of windows and doors, with all measures to prevent dew from falling into the heat-insulating layer. There are many foams in terms of their qualities, and the balloons are selected according to the purposes of use….

Where to apply foam insulation in a private house

If the house is a frame, then the usual technology for this construction is to foam the outer frame with polyurethane foam. These structures include a sloping roof made of wood for all homes. It is easy to insulate by spraying polyurethane foam from the attic side. After spraying, the frame is closed with a dense, environmentally friendly finish, for example, cement particle board. Spraying is carried out by an organization that has the necessary equipment and materials for it.

Spray insulation on the frame

If the walls in the house are double, leaving a space between the load-bearing layer and the outer coating (usually a brick wall), it's time to insulate them. Easiest to do by pouring a foamy substance Penisole. After a while, a slight shrinkage will occur and a layer of effective insulation will remain inside the wall with a thickness approximately similar to a cavity. Also, the foundation can connect the necessary equipment to any horizontal surface, for example, underground. But in this case, it is necessary to provide protection from both steam and rodents.

As we can see, modern methods of insulation simplify construction, and foam insulation can be described as “fast and monolithic”. As a rule, users are satisfied with the use of foam insulation.
