This refers to a specific type of thermal insulation commonly used in residential and commercial buildings. R-19 denotes the insulation’s thermal resistance, indicating its ability to impede heat flow. A 24-inch width specifies a standard dimension for fitting between studs or joists in construction. This particular product is typically available through a major home improvement retailer. As an example, a homeowner might purchase rolls of this to insulate the walls of a newly constructed house.
The importance of effective thermal insulation lies in its ability to reduce energy consumption and improve indoor comfort. Higher R-values signify greater insulating power, leading to lower heating and cooling costs. Historically, advancements in insulation materials and techniques have contributed significantly to energy efficiency standards in buildings, impacting both environmental sustainability and occupant well-being. Choosing the appropriate width ensures proper coverage and minimizes gaps that could compromise performance.
