High density closed cell foam has many advantages over other types of traditional insulation. With a higher R value (thermal resistance, indicating the resistance to heat flow) than most standard insulation products. High density closed cell foam allows very little permeation of air and water vapors therefore it will not mildew or attract other types of fungus.
For construction projects it is best to use a professional installer with the proper training and special tools for mixing. metering and spraying so that you get the best density for your project. High density closed cell foam is an excellent barrier to air and water, keeping heating and cooling inside and moisture out. If you are working towards going green this product offers energy efficiency with no ozone depleting chemicals or formaldehyde.
Using this type of insulation also protects against thermal bridging. Thermal bridging occurs when materials that are poor insulators allow heating or cooling to escape. A good example of materials that act as a thermal bridge is the wood or metal framing used for construction projects. High density foam is used to insulate and act as a barrier against thermal bridging. The thickness of your insulator increases the thermal resistance. The unique spray application allows the insulator to be sprayed directly on surfaces that can conduct thermal bridging. The spray application also allows it to be layered and it expands as it is applied so there are no gaps that reduce the effectiveness of your insulation, unlike traditional fiberglass insulation.
There are many uses and several forms of high density closed cell foam, from styrofoam cups, closed cell foam sheets and SPF (Spray Polyurethane Foam). High density closed cell foam is used not only in insulation and roofing for residential and commercial construction projects but also for insulating pipes, tanks, freezers and flotation material for ships, boats and docks. This product is so strong and durable it is used to increase structural strength in the wings of airplanes. A very efficient insulation product, although the cost may be higher you will re-coop your cost and more with lower heating and cooling bills.
Be sure and do your homework before you decide which insulation product to use for your project. Always check the R Value, the higher the R Value the better your insulation's effectiveness. When you compare cost don't forget to check with your accountant or the Internal Revenue Service for any tax credits that may be available to you.
