Pink Fiberglass Batt Insulation Between Joists In Floor
Close-up of pink fiberglass batt insulation between wood joists in the floor of a residential home under construction. Insulating the floor saves energy on heating and cooling costs. Fiberglass uses raw materials like sand, limestone, and boron that involve issues of resource depletion and pollution from extraction. Choosing insulation with high recycled content will help minimize these problems.
