Our story is not simply a history of insulation or building supplies, or even the dates of inventions and buildings: It’s an intricate tale of innovation and growth spurred by reinvention, curiosity, and strong partnerships built over decades. Our roots reach back to an 1800s lab experiment that, through an unexpected twist, produced mineral wool insulation. This set off a wave of innovation for what would in time become the insulation industry we lead today. Over the decades that followed, we experimented with glass, partnering with organizations along the way to develop new applications and production methods for our innovative products. Owens Corning products make buildings more comfortable, more energy-efficient, and safer. This includes insulation that reduces heating and cooling costs, roof shingles that reflect the sun’s rays and protect the roof from severe weather, and doors that connect you with the people and things you care about most — and make life easier, safer and more beautiful, too.
