When we build a building, to create a comfortable and energy-efficient room, we need insulation materials that are used as heat and sound absorbers. There are several kinds of insulation materials that are often used in construction projects, such as a combination of aluminium foil and glass wool, insulation made from cellulose fibre, bubble-type aluminium foil, and foam insulation made from polyurethane. One of the insulation materials that is often used in building construction projects is foam insulation.
Currently, there are two types of foam insulation that are often used to reduce heat and sound when a building is built. The two types are spray type and coating type. Spray-type foam insulation is known to be more practical and easier to use because it can be used in various areas or parts and it can reach certain gaps to cover the air temperature from the outside.
The second type of foam insulation is the coating type. Foam insulation this type of coating is usually used to coat solid objects such as boards which are usually installed in certain parts. To use this one insulation requires a tool that is attached to the part to be coated with foam insulation. Foam insulation is suitable for coating parts such as roofs or certain areas where the spray is not allowed.
What Is Spray Foam Insulation?
Spray foam insulation is an insulation product that made from polyurethane which is sprayed directly onto the area where you want to insulate. Spraying this insulation is required to use of special protective equipment for workers during the spraying process. This work must also be done by professionals in their fields.
The Advantages Of Using Spray-Type Foam Insulation
Using this type of spray insulation is the most often used because of several advantages, including:
- can reach narrow gaps
- resistant to mildew
- durable in one place
However, this spray foam insulation is considered to have several disadvantages which are currently being discussed a lot about the use of spray foam insulation.
Disadvantages Of Spray Foam Insulation
There are several spray foam disadvantages associated with the use and application of spray foam. In addition, the application of spray foam is considered to cause problems for the environment and residents of the house due to exposure to chemicals contained in the spray foam insulation. This of course has the potential to endanger human health. Those disadvantages include:
- Potential to damage water quality
During the process of installing spray foam insulation on the roof of a house, for example, there will be the potential for gaps to form in the area where the insulation is sprayed, which can increase the potential for water intrusion. This results in decay and the breeding of insects and the potential for fungus to grow.
- Spray foam insulation can shrink
This material has the disadvantage of shrinking with age, changes in temperature, and reduced coverage over time.

- Health issues
When construction workers do not use personal protective equipment when spraying this insulation or improper spraying method, it can cause a dangerous reaction. When foam insulation is sprayed, the process releases vapours and aerosols. That’s what can endanger the health of people around the area of this spray foam insulation installation.
- Takes a long time to dry
After this insulation spraying process, the sprayed part takes a long time until the material is completely dry and can be continued for other processes so that it is considered less efficient in the construction process time.
- Air pollution
This spray foam insulation has a chemical base that has a pungent odor and can pollute the air. It raises the possibility that one day it will cause an odor that pollutes the air in your home. Not only the odor, but these chemicals can be toxic to the health of the occupants of the house when inhaled.
That’s the discussion about the consideration of the disadvantages of spray foam insulation when you consider using this spray foam insulation as a coating material to reduce hot air and muffle the sound. To maintain the health of occupants and the comfort of the environment, maybe you can consider other ways to reduce heat and reduce noise in your home building.
