This is a complete look at a finished eShield™ multi-layer thermal reflective barrier insulation installation. eShield™ is a state-of-the-art insulation product that features both a high R value and E value because of its NASA-created high density fiberglass core. This means, unlike traditional types of insulation, eShield™ protects against all three types of heat transfer: convection, conduction, and emission. This complete protection will result in big savings on energy bills for homeowners. eShield™ can cut energy costs by up to 25%.
