• What is roof insulation?
Roof insulation is a way to prevent heat flow and is – contrary to popular belief – not only important in the winter, it keeps the house cool in the summer and warm in the winter. Insulation also reduces toxic emissions and reduces our energy consumption.
Insulation lasts for a very long time and is therefore one of the important things to maintain the condition of your home. Insulation is also based on three axes, which are radiation, conduction, and convection. Conduction, simple and clear from its name, is the conduction of heat from one place to another through materials. As for convection, it is based on the fact that warm air ascends to the top, while cold air remains at the bottom, and it is transmitted through liquids and gases, and finally radiation is the transfer of heat through solid materials to warm them.
How do you insulate roofs?
Material insulation is based on reducing heat emission by reducing the absorption of thermal radiation. In the summer, heating is replaced by cold, while in the winter, the reverse is done.
• How are roofs insulated?
When you insulate your home, you prevent one of the most common phenomena, which is ceiling burning due to harsh lighting penetrating the ceiling. As for how, there are plenty of options for insulating roofs. The method of insulation will be determined according to the house’s need for it and the areas to be isolated.
There are some types of insulation that can be installed by homeowners, such as blankets and liquid foam, while there are other methods and types of insulation that require professionals and specialists working in the field of roof insulation. Complete insulation is the most widespread, consisting of elastic fibers, natural fibers, plastic fibers, and other materials.
Tiles are placed over the ceiling but with wooden spacers added below. Metal roofs require a barrier to be placed underneath to prevent radiant heat from entering. The metal roof is installed above the parapet.
Floors can be insulated before final finishing by applying insulation boards.

• What are the most popular insulating materials?
1. Cellulose:
Cellulose is a material made from recycled paper, such as newspaper. About 85% of recycled paper is cellulose.
Cellulose is manufactured by breaking down paper into very small pieces that are converted into fibers that are placed in specific places such as cavities in walls and ceilings. Cellulose blocks airflow, and cellulose often contains ammonium sulfate, which is known to be fire retardant.
Cellulose is the cheapest insulation material.
2. Polyurethane:
Polyurethane is a material made of foam and its pores and cells consist of a gas with a low conductivity. This foam exists in two forms, either closed cells or open cells. The high density cells are sealed and filled with gas which expands the foam by filling the pores and voids around the gas. As for the open cells, they are not filled with air and have a low density, which gives the insulation material a spongy feel.
Open cells are often volatilized and replaced by air as their density and quality decrease over time.
3. Urea Formaldehyde Foam:
This foam is considered one of the first insulation materials to be used in homes, but after a while it was banned from use due to the emission of some toxic substances from formaldehyde
4. Vermiculite and Perlite:
In the year 1950 AD, vermiculite and perlite were discovered and used as insulation materials in homes. Now they are not widely used because they contain asbestos.
Insulation is often done on the inside or outside of ceilings, or in exterior walls or floors. To get the best possible insulation method, it is preferable to consult a specialist in the installation of insulation materials.
