isolation
Insulation forms a barrier that prevents the flow of heat, and is important. to maintain the temperature of the house in summer and winter; It makes the house cool in the summer, and warm in the harsh winter, just as insulation reduces energy consumption and reduces the emission of toxic gases that cause global warming.

The principle of roof insulation includes three factors: radiation, conduction, and convection. Conduction is the pathway through which heat travels through materials, while convection is the circulation of heat through liquids and gases. So the warm air rises to the top, and the cold air stays below so that it fills the house.

As for radiation, it works to transfer heat in a straight line to help warm any solid thing that passes through it, and the principle of action of famous insulating materials lies in reducing heat emission; Since insulating and heat-reflecting surfaces reduce heat radiation gain; Where the heating system is replaced by cooling in the summer, and vice versa in the winter.

How to insulate surfaces
Ceiling insulation is one of the important and necessary things for buildings. This is due to the increase in the phenomenon of ceiling fires resulting from the penetration of lighting into the ceiling. As for how to insulate homes, there are many options and types that are determined based on the extent of the need to install insulation and the spaces that are isolated. to be insulated in the home, and homeowners may be able to install some of these themselves.

Such as: blankets and insulators that pour easily (liquid foam), and there are other types that need technicians, specialists, and specialists in the installation of insulating materials, and complete insulation is one of the most widespread types of insulation; It consists of fibers characterized by their flexibility, glass rolls, natural fibers, and plastics, where these insulating materials are found in the form of hoses.

The insulation process is done by placing tiles on top of the ceiling, and wooden spacers can be added under the tiles. As for ceilings made of metal, they need a barrier directly below it, as this barrier represents a layer that forms a barrier to radiant heat, then the metal roof is re-installed above this barrier without negative consequences.

As for the floors, they can be isolated by placing insulating panels before finishing the floors, and with regard to the concrete panels, they are isolated by the cooling and heating system (located in the ground and around the vertical edge of its perimeter, where the insulation is an R value of not less than 1.0). .

some insulation materials
Insulating materials consist of a group of materials that in turn insulate surfaces from heat, such as glass fibers, cellulose, wool, foam boards, and mineral insulation materials made of wool, as well as natural insulation materials made of sheep’s wool, straw, and cotton. .

cellulose
Cellulose is one of the insulating materials for the roofs and ceilings of houses, and it is a material made from recycled paper, such as newspaper paper, as this insulating material contains a large proportion of recycled (recycled) materials, representing 82-85 percent of this material, and the principle It is manufactured by reducing paper to small crumbs, then converting it into fibers that are placed in designated places, especially in the cavities of buildings and ceilings

in order to prevent air flow through them, and the manufacturers of these materials add borates combined with ammonium sulfate; In order to resist fire, what distinguishes this insulating material is its low cost compared to other insulating materials. As for the uses of cellulose in built and existing homes, they are placed in the cavities of ceilings and walls.
