What is the thermal resistance?

The heat resistance is a measure of the ability of the material to withstand heat transfer. The more the material is able to block heat transfer through its surface, the greater the thermal resistance. This concept is often applied to the building industry as a measure of the effectiveness of insulation and energy efficiency. Once the building has been added to the building to improve the level of efficiency, the heat resistance of the structure increases.

For most of the world, R-value is used to measure thermal conductivity and resistance. In the US, the value R is a measure of heat transfer in terms of Fahrenheit and British thermal units (BTU). Throughout the rest of the world, the value of R is provided using the international system of units (units) and is measured in terms of BTU and degrees Kelvin. The higher the R value, the better it is able to withstand heat transfer. The lower the R value, the easier it is to pass the heat through the surface of the material.

house owners who are interested in improving the energy efficiency of their house should look for materialY with a high R value to function as insulation. The insulation can be added to the outer walls, roofs or foundations to improve heat resistance. While basic building materials, such as brick, concrete and plasterboard, offer some resistance to heat transfer, they often have relatively low R values ​​compared to actual insulating products. To determine the value of the r wall or roof assembly, add the individual values ​​R for each component. For example, the R for the brick wall would be equal to the sum of R brick values, moisture barriers and any inner plasterboard or insulating materials.

Slum fiber or woolen blankets are among the most popular insulation products used to improve heat resistance. These materials are affordable, easy to install and easily accessible in most areas. They are also one of the poorest, especially compared to more efficient products such as spray foam or solid foam plates. Some builders can also useto tie freely full cellulose or green products made of recycled denim or cotton to serve as an insulation.

The

given r-value of the material shows its ability to withstand thermal transmission under perfect conditions. This means that the insulation must be properly installed and maintained as recommended by the manufacturer. When insulation is compressed, it loses a large amount of its properties of thermal resistance. Insulation may also fail when wet or moldy, or if there are insufficient amounts to fill the wall cavity.
