Why spray foam?
spray foam
Refractory foam spray is the same as fireproof polyurethane foam that has high fire resistance. In addition to being a good insulator against fire, this foam also works well against heat transfer and noise pollution and prevents the passage of these items. However, if you want to know more about this type of insulation, join us till the end of this article.
Polyurethane refractory foam spray:
It has high adhesion and adheres well to all surfaces. Of course, do not forget that this coating foam does not stick to silicone, Teflon and polyethylene and It does not contain any CFC, HCFC or HFC gas.
It should be said that this substance does not pose any danger to the ozone layer and the environment.
In addition, it is very efficient, durable and lightweight you can use it in different places.
Advantages and specifications of fire retardant polyurethane foam:
First of all, you need to know that refractory foam spray is applicable in the shortest time and you can cover the highest level of this foam in a short time. It should also be said that this spray:
* Resistant to fire and flame for more than 200 minutes.
* Good sealant against smoke and gas.
* It has high durability against moisture and melting.
* It has very good adhesion to materials.
It is also possible to sand, cut and paint the foam after drying. In addition, it can be washed and cleaned.
Application of polyurethane fireproofing foam spray:
One of the main applications of polyurethane refractory spray is its use as a fire-retardant sealant.
In fact, you can use this polyurethane foam to sealant all surfaces, holes and cavities that should be protected from smoke and fire.
This foam can be applied on floors, walls and ceilings and also:
* It is also used as a sealant against heat and cold.
* It is also used as sound insulation.
* Used to repair cracks and fractures in pipes.
* Used to insulate against cold, heat and humidity.
How to use polyurethane thermal spray:
- To use this product, it is necessary to carefully clean the desired surface. Then wet the surface a bit.
- Shake the can before consumption.
- Hold the can down and spray to the desired surface.
Keep in mind not to use spray foam in unventilated environments for the duration; Because you may feel dizzy and bored. Also, thoroughly clean the outlet pipe of the can after finishing work. Then place it in a dry environment and normal temperature.
Refractory foam spray or polyurethane thermal insulation is one of the best coatings with which you can cover any seams and cracks and prevent them from spreading while securing against fire.
This insulation can also be used as sound, heat and moisture insulation.
Warning about using spray foam insulation:
The chemicals used in the spray foam can be immediately dangerous to a person's health if not used properly. You may be at risk for asthma or other respiratory problems, along with eye and skin irritation, if the foam is not completely repaired and you are exposed to the harmful chemicals in the spray.
Does mould grow on spray foam insulation?
Most mould consulting companies have found that when foam spray is installed in an area, it is not affected by mould and prevents contamination forever. Sealing spaces such as attics can reduce or even make zero the humidity needed for bacteria and fungi to grow.
Can rats eat through spray foam insulation?
Expansion foam is resistant to rodents and also filling gaps and voids with polyurethane foam acts as a barrier for rodents because mice and other rodents are not able to chew through the foam insulation.
why we should use spray foam insulation?
Foam insulation saves energy costs. Studies by the US Department of Energy show that 40% of a building's energy loss is due to air infiltration through walls, windows and doors. Buildings covered with spray foam insulation are usually up to 50% better insulated than traditional insulation, protecting buildings from moisture erosion and reducing the growth of harmful bacteria such as mould, odours and fungi. Very useful. These properties are very important in poultry and livestock. In addition to maintaining the building temperature and controlling humidity, foam spray is an insulation that is often used to reduce noise. Foam insulation acts as a barrier against ambient noise and reduces the transmission of sound through the air through the building to the ceiling, floor and walls.
Closed-cell polyurethane spray foam is used to apply waterproofing in places where it is not possible to expand the insulation. Because this type of insulation has high reliability.
spray foam insulation advantages:
* Moisture removal
* Easy to install
* Gives more strength to buildings
* Reduces sound
* Help regulate the indoor air of the house
*to be cheap
* Reduce bill costs
* Resistance to rodents
Disadvantages of foam spray insulation:
* it can be harmful to health
* If installed incorrectly can be problematic
When not to use foam spray insulation?
- For areas that are very close to power boxes
- For closed spaces
- If you have a history of skin, respiratory or asthma problems
Some salient features of spray foam:
Very high execution speed (for the daily building of 300 and shed of 700 square meters)
Access to building blind spots such as installations, roofs, pipes, ducts and fittings
Impermeable to water and moisture and washable
Lightweight building
Excellent adhesion without the need for glue, screws and welding
40 years of useful life
50- Temperature resistance up to 110 degrees Celsius
Grade B2 self-extinguishing
Has the standard of the American Materials Association and ASTM test
Safety items:
Foam spray insulation is somewhat dangerous to humans when sprayed. If you do not have proper safety equipment and proper clothing, the particles can damage the eyes, skin, or the body if inhaled through the mouth and nose. Chemicals can irritate the eyes and respiratory system and cause inflammation or irritation of the skin. It is recommended that people wear safety goggles, respirators, gloves, long-sleeved clothing, and long pants when spraying foam insulation.
