Ductless Air Conditioning Units in Hammond – What Is Rigid Insulation?
Rigid insulation is a building material used to provide thermal resistance to walls, foundations, and roofs. It is available in formed or extruded sheets of varying sizes, which are made from polystyrene or polyurethane. This material helps to improve the energy efficiency of a home by keeping cold or hot air from penetrating the walls.
The thermal resistance of rigid insulation is measured by the material's R-value. Higher R-values mean that the material is more resistant to temperature transfer, while low R-values mean that air can easily pass into or out of the home.
Rigid insulation may also be installed on roofs or foundations. Roof panels must be dense enough to walk on, and are usually installed above the roof framing, but below the roof tiles or shingles. Water-resistant rigid panels can be placed on the exterior of foundations, but it is more common to install them on the interior of basement walls, or below a ground-level floor. When installed on the exterior of the foundation, the panels can be treated with insecticides to prevent termite damage.
Mini Split Air Conditioner System in Hammond – Types of Rigid Insulation.
There are three main types of rigid insulation, and each offers its own benefits and drawbacks. Molded expanded polystyrene (MEPS) is made sheets formed from liquid polymers. This is the most affordable and most common type, of rigid panel and is often referred to as beadboard. Extruded expanded polystyrene (XEPS) is more expensive, but is also stronger and denser, making it well suited for roof installations. Polyurethane foam board is the thinnest of the three, and works best in small spaces or in homes subject to extreme temperatures.
