High in performance, Nu-Seal is a hybrid foam insulation system that contains high biological raw material and low embodied energy. These attributes make Nu-Seal one of the greenest foam insulation systems in the marketplace. Nu-Seal passes all ASTM testing for foam insulation products and is a Class 1 rated insulation product. Formulated exclusively for resale by Nu-Wool Co., Inc., the oldest cellulose insulation manufacturer in the world, Nu-Seal foam is the best product to complement cellulose insulation to cost-effectively seal a structure’s thermal envelope.
The Nu-Seal Foam Insulation System, manufactured by Natural Polymers, LLC, is the recommended GREEN alternative to fiberglass batting and other petroleum based foam products for use to insulate rim joists, knee walls, cathedral ceilings, and other areas difficult to spray with cellulose insulation.
Traditional chemistry used to make foam insulation is based solely on petroleum building blocks. Utilizing renewable content such as natural agricultural oils and sucrose, the amount of petroleum in Nu-Seal Polyurethane Spray Foam is reduced by 15-30% compared to other 100% petroleum based foam systems.
As a result, Nu-Seal contains more renewable content, but still maintains the performance and physical properties of 100% petroleum based systems- truly a GREEN product. In addition to using less petroleum in the development process, Nu-Seal 0.50 is water blown instead of chemically blown, which is also better for the environment.
