Closed-cell spray-in-place polyurethane insulation

InsulStar ® is the most energy-efficient, environmentally friendly, closed-cell spray-in-place polyurethane insulation system available. It is formulated from renewable agricultural resources and is odorless and completely non-toxic after installation. It stops air flow into and out of your home, reduces noise, and blocks dust, pollen and other airborne pollutants for a more comfortable environment.

InsulStar is a two-part liquid that is sprayed in place by specially trained Gold Star ^SM contractors. This liquid quickly expands, filling all gaps and voids, conforming to any shape space and cures to form a fully adhered, solid, monolithic insulation envelope. InsulStar's high R-value allows designers to reduce the depth of exterior walls and still obtain high energy efficiency. (BASF has an R-value of 5.6 in the 1st inch and 5.1 after that, according to an ICC Evaluation (PDF 151 KB). BASF claims an R-value of over 6.0 per inch.) This means more living space in your home. By simply changing the exterior walls from 2" x 6" studs to 2" x 4" studs, a 2,500-square-foot house gains almost six square feet of living space, reducing the wood required and saving two trees.

InsulStar forms an air barrier that seals the walls to prevent air penetration and block outside noise pollution, giving you a quieter home. The closed-cell structure of InsulStar blocks air movement and has a low permeance, which controls moisture vapor movement, eliminating the need for an additional vapor barrier. When moisture vapor is controlled, condensation will not occur, thus eliminating the water to support mold growth. Additionally, InsulStar is blended with an anti-microbial to inhibit mold, mildew and bacterial growth.

Polyurethane Insulation: Conserving Tomorrow's Energy Today

By designing and building a highly energy-efficient home, the reduction in energy demands for heating and cooling will lower demand on utility companies for the life of house. With InsulStar you can insulate directly to the roof deck, bringing all of the space under the roof into use. By putting HVAC ductwork in conditioned space, energy waste from leakage is eliminated. The additional conditioned space can then be utilized for computer rooms, bonus rooms, playrooms, or closet space. Previously wasted attic areas become valuable living space for very little cost, while adding tremendous retail market value to the house.
