When it comes to regulating interior temperatures, building insulation is a key consideration.

It is one of the most fundamental solutions in building design and comes in a wide variety of materials, types, and uses. Heat moves from warmer to cooler locations, so insulation improves building efficiency by slowing down heat transfers through walls, floors, and ceilings. The better the insulation, the slower heat moves through building enclosures, and the more energy savings you can gain. In some cases, there may even be utility incentives for achieving certain levels of insulation in a building.
