Product: Icynene Insulation System, www.icynene.com.
Remodeler John DeCiantis learned about the Icynene Insulation System while attending a trade show several years ago. He decided to try the product. "What sold me on it was that Icynene does not allow air to pass through," DeCiantis says. "It does a phenomenal job of deadening sound. It doesn't allow condensation to form, so venting [in a roof application] isn't necessary."
The system is applied by licensed Icynene dealers, who mix the two-part formula on site. The free rise, open-celled polyicynene material expands in open walls, crawl spaces, and ceiling surfaces in seconds, forming to the space, sealing cracks and crevices, and preventing convective air movement.
DeCiantis says that although application is messy, the benefits far outweigh the inconvenience of cleanup. "The more we learned about it, the more applications we found it suitable for, such as cathedral ceilings and roofs with hips and valleys."
