Bayer MaterialScience insulation not only provides an extremely high R-value but the ability to minimize air intrusion, accumulation, radiative heat transfer and air movement. The application technology allows the spray polyurethane foam to expand, filling cracks, crevices and voids. This creates a seamless air barrier system that provides optimal building envelope performance. This specification includes the following spray foam insulations.
- Bayseal OC open-cell polyurethane foam technology offers a complete air barrier system. Buildings insulated with Bayseal OC provide occupants a quieter and more comfortable indoor space. Bayseal OC adds significant energy efficiency value by filling open voids, cracks and crevices during installation. Bayseal OC insulation is recommended for walls, attics, ceilings and floors. Bayseal OC offers an aged R-value of 3.9 per inch.
- Bayseal CC is a closed-cell foam seals the building envelope to create an optimal energy efficient environment. Bayer MaterialScience insulation is recommended for non-vented attics, ceilings, floors, foundations, piping, and non-vented crawl spaces. Bayer MaterialScience offers an aged R-value of 6.9 per inch.
- Bayseal CC POLAR is a hybrid formulation of the Bayseal CC closed-cell foam insulation material. This hybrid formulation was specifically designed for cold substrate applications to extend the insulation season in cooler climates. Bayseal CC POLAR adds durability to the structure and seals the building envelope to create an energy efficient environment. Bayseal CC POLAR insulation is recommended for non-vented attics, ceilings, floors, foundations, piping, and non-vented crawl spaces. Bayseal CC POLAR offers an aged R-Value of 6.9 per inch.
- BaySeal CC X and CC XP spray-applied poly- urethane foam insulation is a two component, HFC- 245fa blown, medium density, structural system designed for commercial, industrial and residential insulation applications. Bayseal CC X system has passed the International Code Council Acceptance Criteria 377, for spray- applied polyurethane foam insulation, Appendix X for use without the use of the prescribed ignition barrier and without the need for additional fire resistant coating.
- EcoBay CC is a closed-cell foam seals the building envelope to create an optimal energy efficient environment. Bayer MaterialScience insulation is recommended for non-vented attics, ceilings, floors, foundations, piping, and non-vented crawl spaces. Bayer MaterialScience offers an aged R-value of 6.9 per inch.
