Polyurethane foam is a very versatile material that is used in different areas: office renovations , housing construction , ships, airplanes, etcetera. If you want to know what polyurethane foam is and what it is for , read on and we will explain it carefully.
Polyurethane is a substance created from a chemical reaction . It is a combination of polyol and isocyanate that makes this material can be molded and handled without losing its physiology.
The polyurethane can be crushed, scratched and stretched without any problem, being a tremendously resistant material that can be used in solid, liquid or foam. In the case in question, it is used in its liquid state and after being applied it tends to expand until it acquires its solid form.

It has a multitude of properties that work very well in the construction sector: water-repellent insulation, thermal insulation and as an anti-humidity material .
In this way, the polyurethane foam acts as a thermal bridge and, in addition to strengthening the structure , eliminates the transmission of cold and heat . This supposes a considerable saving in matter of refrigeration and heating.

In addition, its structure is resistant to water , so it is perfect for all types of structures, whether irregular or showing imperfections. Thus, polyurethane foam prevents leaks and protects against corrosion .
Uses and application
- It works as an insulating substance in ceilings, basements, walls and attics.
- It is used in insulation panels .
- As insulation in the industrial sector in cold rooms, tanks, etc.
- It is effective in boats, floating docks and ships .
- It serves to enhance the structure of the wings of the aircraft .
- It is also used in bodies .
Other uses
- The polyurethane foam prevents roofs from rising and increases the strength of the wooden frames inside the walls.
- It serves to fix irregularities in the walls , as well as to fix PVC pipes .
- It is used in roofs, being very useful in the construction of drainages and to increase the resistance to abrasion .
The main advantages of polyurethane foam
- Polyurethane foam contributes to the environment . It is used to save energy, so it moderates global warming by reducing the consumption of fossil fuels .
- Polyurethane strengthens any structure and makes it resistant to vibrations, wind and storms.
- Used inside buildings, it means a considerable saving of money in cooling and heating.
- As a structural sealant, it is a magnificent noise insulator .
- Its properties last in time without hardly any wear and tear.
- It potentially reduces the growth of the bacteria and the mold that usually take shelter inside the structures.
- Its use is very simple and its adhesion is magnificent, without the need to use other methods or systems as extra adhesives.
- It effectively reduces the filtration of certain external elements that are contaminants such as gases.
- It is very easy to transport , as it is not a bulky substance that requires special storage.
