HeiQ XReflex(TM) is an innovative radiant barrier technology that reflects heat back to the body maintaining the same level of warmth with as little as half the insulation material. It’s an ultra-thin heat reflective surface added to one side of the fabric by high-tech vapor deposition which reduces insulation bulk by up to 50%, making it the perfect solution for a wide range of applications. HeiQ XReflex is an advanced system comprised of recycled materials that are recyclable and, because it needs less insulation material, it’s a more sustainable option.
