Carpet is a natural insulator, trapping air in its fibers, and providing additional warmth in cold seasons. And it has the potential to save you money on utility costs while reducing energy usage.
Carpet’s Insulation Capacity
The use of carpet in a wall–to–wall rooms increases the R–value‚ or insulation level‚ of the space. The R–value measures how much a material resists the movement of heat through a ceiling‚ wall or floor in a building. The higher the number, the more effective the insulation. Results vary according to the carpet’s construction, with heavier products generally providing higher R–value. Testing confirms that carpet with cushion underneath significantly increases the R–value compared to other flooring materials.
While cost savings will vary based on a number of factors such as the floor construction, local energy costs, climate and carpet/cushion type, carpet with cushion represents a clear advantage in insulation capability.
