What is strict insulation?

Insulation is a building material used to ensure heat resistance to walls, foundations and roofs. It is available in formed or extruded leaves of various sizes that are made of polystyrene or polyurethane. This material helps to improve the energy efficiency of home by maintaining cold or hot air before the wall penetration. The heat resistance of solid insulation is measured by means of R. higher R value means that the material is more resistant to temperature transmission, while low R values ​​mean that air can easily pass to home or out of home. The resulting reduction in energy consumption also benefits the environment, leading to a smaller number of greenhouse gas emissions. While many types of insulation can perform this function, solid insulation generally provides higher thermal resistance than other materials of similar size. The rigid paels are thicker and thinner than other insulating materials and can be installed with a smaller number of spaces or joints, resulting in less air leakage. The panels are placed firmly together and the joints can be sealed or sealed to provide maximum thermal resistance. In situations where the possibility of moisture infiltration, the insulation can be covered with water -resistant coating.

solid insulation can also be installed on roofs or foundations. The roof panels must be dense enough to walk, and usually install the roof, but under the roof tiles or shingles. On the outside of the foundation can be placed rigid rigid panels resistant to water, but it is more common to install them on the inside of the basement walls or below the floor level. When installed on the exterior of the foundation, the panels can be treated insecticides to prevent damage to the termites.

There are three main types of solid insulation and each offers its own advantages and disadvantages. Pressed expanded polystyrene (MEPS) are produced leaves made up of liquid polymerat. This is the most affordable and common type of rigid panel and is often referred to as beadboard . Extruded widespread polystyrene (XEPS) is more expensive, but is also stronger and denser, which is well suitable for roof installation. The polyurethane foam plate is the thinnest of three and works best in small spaces or in houses subject to extreme temperatures.
