thermal insulation
Thermal insulation is defined as a means that aims to prevent or limit the transfer of heat between objects by all methods of heat transfer; Such as thermal contact or radiation, and heat is considered a type of energy, and heat transfer occurs due to the transfer of energy between bodies that differ in temperature, and stopping this transfer in heat is done by using thermal insulators, as these insulators provide a means to maintain the temperature gradient during The wall, by providing an isolated area that reduces heat flow or reverses the direction of heat transfer instead of absorbing this heat by the surface. Insulation materials are selected under certain conditions, taking into account a set of multiple factors.

Thermal insulation benefits

Reducing the consumption of electrical energy in buildings, as scientific experiments have proven that buildings that use thermal insulation reduce the use of electrical energy by 40%.
Constant temperature in the building for a long period of time without the need to use air conditioning or heating.
Reducing the need to use high-capacity air conditioning and heating devices, and thus reduce energy consumption, and the number of devices used.

Increasing the level of comfort for the residents and users of the building.
Reducing the health impact of the use of air-conditioning and heating equipment from respiratory problems and the resulting noise.
Protecting the building structure from weather changes, the temperature difference between night and day, and between winter and summer, which stresses walls and windows, loses their mechanical properties, and causes cracks, cracks and cracks.

Reducing the thickness of the concrete walls.
Reducing the burden on power and electricity production plants.

Thermal insulation methods
The use of thermally insulated bricks in construction
This method is considered one of the most widely used methods at the present time. The wall is built of bricks with a thickness of 20-25 cm of insulated bricks. Inside the bricks are strips of thermal insulation materials; Such as: polystyrene or rock wool.

The use of an insulated block wall along with the original construction
A wall of thermally insulated bricks with a thickness of 20-25 cm is used, after which a white concrete wall is added.

Putting a sheet of thermal insulation between the two walls
Two walls 30 cm wide are built, and thermal insulation panels are placed between them; Such as polystyrene and rock wool or polyurethane, where the thickness of the insulating material is approximately five centimeters.

Thermal insulation of the building from the outside
The building is insulated from the outside by covering the building with marble, granite, metal panels or other materials that can be installed and installed, where a material of thermal insulation is placed before the building is covered.
