1. Icynene Foam Insulation The Icynene Insulation System By Eric Goodman MEEN 3344

2. What is it? 100% water-blown polyurethane foam insulation. 99% air, 1% material Open cell material. Has a ½ lb density under free rise.

3. Advantages Effectively insulates all types of construction material. Reduces monthly energy cost by 50% each month. Perfect insulator for walls, ceilings, and floors. Enhances sound proofing, and improves indoor air quality. Not a food source of mold. Will not melt or drip.

4. Disadvantages Prone to infestation of wood boring insects, which could reduce thermal performance. Accumulation of dust and dirt could fill in air pockets of insulation over long periods of time. More expensive than batt or loose- fill insulation Messy process, requiring clean up and protection. Excess water in wet-spray applications may lead to rot and mildew.

5. Application Expands to 100 times its volume in seconds to fill every crack and crevice, while remaining flexible over time. Acts as complete insulation and air barrier to minimize air leakage and seal the building envelope for optimal air tightness.
