Icynene® Spray Foam Insulation

Icynene® spray foam insulation products create a superior air-seal, effectively minimizing air leakage to deliver advanced moisture control, healthy air, and cooling and heating energy savings of up to 50%. Icynene® outperforms traditional fiberglass and cellulose insulation materials by providing ideal R-value levels and air sealing in one step, without the need for additional labor-intensive sealing materials.

Icynene offers an array of light and medium density spray foam insulation products that are ideal for both residential and commercial construction. All of Icynene’s light density spray foam products are 100% water-blown and contain no harmful blowing agents that can compromise indoor air quality. Plus, Icynene’s newest medium-density closed cell product, ProSeal Eco, is 100% water blown. It’s the first spray foam product of its kind in the world.

Icynene Classic™

Icynene Classic™ (LD-C-50®) is the product that made the Icynene name synonymous with superior quality, open-cell, 0.5 lb., light density spray foam insulation. Icynene Classic™ has been used in thousands of projects for over 25 years and is the industry benchmark for quality and innovation by which all other light density insulation products should be judged.

Icynene Classic Max™

Icynene Classic Max™ is the industry’s safest and most economical spray foam insulation option available for builders and homeowners looking to protect their homes from the risk of attic fires spreading. Icynene goes beyond the industry standard with End Use Configuration testing.

No other spray foam insulation product has been as extensively fire tested, nor performs like Icynene Classic Max™. In collaboration with the ICC Evaluation Service (ICC-ES) and an ICC-ES accredited fire consultant, Icynene developed a series of comprehensive end use tests and computer modelling that meet the industry’s ASTM E84 requirements. Only End Use configuration testing can simulate actual attic fires.

Icynene Classic Max™ is recognized by the ICC-ES as an ignition barrier free product.

Since unvented attics represent a significant portion of residential spray foam applications, an ignition barrier free product is a more cost effective application, enabling installation in more homes without delay to construction schedules.

Plus, a one-step application eliminates the need for additional visits and removes the difficulty of applying an ignition barrier as well as the liability of a poorly installed ignition barrier.

Icynene Classic Plus™

Icynene Classic Plus™ is a high R-Value open cell innovation from Icynene that lets you achieve R-22 in 2x6 wall assemblies. Icynene Classic Plus™ is simply the best in class open-cell spray foam product available on the market with High R-Value (Ideal for building types I-V), remarkable adhesion to allow for layering and ability to maintain its water repellant characteristics. Icynene Classic Plus™ lets you meet and exceed the latest regional and national building codes.

No other open-cell spray foam product matches the superior performance of Icynene Classic Plus™. With an incredible R-Value of 4 per inch, Icynene Classic Plus™ is ideal for architects and builders in areas requiring a higher R-value to meet the latest building code requirements.

Icynene Classic Eco

Icynene Classic Eco™ (LD-R-50®) is a renewable based, 0.5 lb., 100% water-blown spray foam insulation and air barrier material. Icynene Classic Eco™ exceeds the renewable content specification set by the USDA BioPreferredSM program and ICC-SAVE. Using high-yield castor oil material, Icynene Classic Eco™ reduces the need for petroleum-based polyol. Castor oil is a natural ingredient that is safe enough for use in personal care products such as lip balm.

Icynene Classic Eco™ is an environmentally preferable product that is 100% water-blown and free from HFCs and PBDEs. It insulates and air-seals in one step for maximum energy conservation while minimizing the environmental impact during manufacturing and construction.
