What, Exactly, is Icynene® Insulation?

Icynene® is a low-density, open-cell, semi-flexible foam insulation. So what does that mean?

Low-Density: Icynene® insulation is very light weight. It is installed by spray, and expands up to 100 times it's original size before drying.

Open-Cell: Icynene® foam insulation is described as having a consistency similar to angel food cake or meringue. It is composed of many small "cells" that make it possible for the material to breathe.

Semi-Flexible: Icynene® foam insulation will not lose it's seal with the natural small movements within a structure. It is not rigid, and is designed to make small movements if necessary.

Icynene® is installed only by trained and licensed dealers. Liquid components are sprayed onto open walls, crawl spaces, or ceilings. The components expand within seconds to fill in all building cavities while sealing any cracks or crevices.

Icynene® is completely cured within just a few minutes.

Excess material is trimmed off so that drywall or other materials can be applied.

When Do I Need to Decide To Install Icynene® or Foam Insulation?

Before the framing stage.

Because Icynene® offers a very tight seal, some additional venting systems will usually be required, and need to be installed before the foam insulation.

Icynene® or other foam insulation is applied just before drywall stage, after framing. All plumbing, electrical, and HVAC rough ins should be complete, as well as all inspections.

How Effective is Icynene® Spray Foam Insulation?

Foam insulations generally offer twice the R value per inch thickness as standard fiberglass batt insulation. Manufacturers and installers say that installing Icynene will save 30-50% on energy costs. Not only that, the tight seal may mean that a smaller or less expensive heating and cooling system can be used.

Installing Icynene® insulation will also go very far towards getting ENERGY STAR or Green Building LEED certification.

Icynene is touted as being an effective sound barrier, and noted as greatly reducing noises from outside the building while reducing echoes within it, particularly those of voices or stereo/tv.

Insulation is not normally installed in interior walls, but could be installed in a particular room for further sound reduction. For instance, installing insulation in the interior walls of the master suite could allow better sleep for a spouse who works night shifts and sleeps during the day.

Are there any harmful fumes or vapors?

Icynene® is safe for both the homeowner and the environment. It has been extensively tested in both Canada and the United States, and no VOCs were detected after 30 days. Icynene® is water-based, and does not produce formaldehyde, CFCs or HCFCs.

Not only that, Icynene is recommended for use in homes for many environmentally concerned or sensitive people. The Icynene Insulation System® has been selected as a product for use in American Lung Association Health House projects.

The total dollar amount will vary greatly depending on the square footage and footprint of the home. In general, this type of insulation costs 3-4 times a standard fiberglass batt insulation.

Another option? Some homeowners opt to install Icynene in just a few locations, like underneath the roof in the attic and around doors.
