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, and the Babylonians also used it to paint houses. Building insulation is very important to control the temperature of the house throughout the year.

• What is foam 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 that this insulation method has.
Among these features:
1. Foam insulation is double insulation. Double insulation is characterized by its ability to insulate both water and heat.
2. Foam insulation is time-saving as it does not require a lot of time to install, unlike other types of insulation.
3. The quality of foam insulation does not decrease until after a long period of time due to its thickness and density. The life span 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 energy use in homes.
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 characterized by its light weight, and no type of insect lives inside it, nor does any type of fungi grow on it. It is also thick to the point that 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 ability to conduct heat and its inability to absorb water or steam except in proportions that do not exceed 1%. Polyurethane is also lightweight and resistant to pressure.
There are two types of polyurethane as 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 suitable ways to resist variations in weather conditions and climate changes.

2. White and blue foam/polystyrene:
The white and blue foam is a semi-plastic material through which air can circulate. Polystyrene is lightweight, 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 very easy as the panels apply in seconds. The two types of panels available are regular panels and interlocking panels. The last type is better. White and blue foam can also be divided into two types: foam formed by extrusion and the other formed by molding.
Extruded foam insulation is low in price and is characterized by its high density, light weight, ease of installation, and ability to resist pressure, so it is the ideal choice for many people.
As for molded foam insulation, it is lower in density and quality.

• Mistakes that should be avoided while installing foam insulation
There are many mistakes that workers make while installing foam. These errors lead to reducing the efficiency of foam insulation and not achieving the desired results. For example: distributing the foam unevenly and installing the foam on metal materials and connections that must be treated professionally.
