What is foam wall insulation?

Insulation is one of the oldest engineering terms that has been applied for thousands of years to protect homes. Insulation was applied by the ancient Egyptians to protect their homes and preserve mummies. The Babylonians also used it to paint houses. Building insulation is very important to adjust the temperature of the house throughout the year.

What is foam wall insulation?

Homes are exposed to many problems as a result of climatic problems that occur throughout the year, whether humidity, rainfall or high temperatures. Foam insulation appeared to get rid of these problems due to the many advantages of this method of insulation.
Among these features:

• 1. Foam insulation is a double insulation. Dual insulation is characterized by its ability to both waterproof and thermally.
• 2. Foam insulation is time-saving, as it does not require much time to be installed, unlike other types of insulation.
• 3. The quality of foam insulation does not decrease until after a long period of time has passed due to its thickness and density. The shelf life of foam insulation is longer than
• other types of insulation.
• 4. Foam insulation is cheaper than other types of insulation.
• 5. Foam insulation significantly reduces our household energy use.
• 6. Foam insulation prevents water leakage.
• 7. The homeowner can control the density of the foam insulation layer according to his desire.
• 8. Foam insulation is light in weight and does not contain any kind of insects and does not grow any kind of fungus on it, and it is thick to the point where it is difficult to penetrate.

• What are the types of foam insulation?
1. Polyurethane:

Polyurethane is one of the organic materials that is characterized by its low thermal conductivity and its inability to absorb water or vapor except at rates not exceeding 1%. Polyurethane is also lightweight and pressure resistant.
There are two types of polyurethane as an insulation material. The first type is the solid type. This type comes in the form of ready-made panels. The second type is the liquid type that is sprayed on the walls.

Insulation using polyurethane is one of the most appropriate methods of resisting weather and climatic changes.

2. White and blue foam / polystyrene:

Blue and white foam is a semi-plastic material that allows air to permeate. Polystyrene is light in weight, contains many voids, does not leak water, and is not a good thermal conductor. Polystyrene has many densities, and the higher the density of polystyrene, the greater its hardness and its ability to resist thermal conductivity. Of course, the higher the density, the higher the price.

White and blue foam insulation is so easy the panels set up in seconds. The two types of panels available are regular panels and interlocking panels. The latter type is better. White and blue foam can also be divided into two types: extruded foam and molded foam.

What is foam wall insulation?

Extruded foam insulation is low in price and is characterized by its high density, light weight, ease of installation, and its ability to resist pressure, so it is the ideal choice for many people.
Molded foam insulation is lower in density and quality.

• Mistakes that must be avoided during the installation of foam insulation
There are many mistakes that workers make during the installation of foam. These errors lead to a decrease in the efficiency of foam insulation and the failure to achieve the desired results. For example: distributing foam unevenly and installing foam on metal materials and joints that must be treated professionally.
