Instant Bill Reduction – Utility Bills have doubled since 2004, don’t get caught out. Icynene will instantly reduce your energy bills up to 35%
The R values of an insulation material can determine it’s suitability for a household renovation or upgrade project. Insulation in your home provides resistance to the heat flow. The more heat flow resistance your insulation material provides then the lower your cooling and heating bills will cost. A correctly insulated home can also improve air quality and general comfort around the home.
What Are Insulation R Values?
An insulation material’s resistance to heat flow (conductive) is measured in terms of thermal resistance, commonly known as R Value.
By insulating with a higher R-Value material the greater the insulation effectiveness will be. There are many factors that must be take into consideration when determining it’s R Value including the type of insulation, it’s thickness and the density of the product. Sometimes homes use multiple layers of insulation so to calculate the effectiveness of this you must calculate the combined R values for a total.
R Value Of Icynene
Icynene’s low density foam insulation offers a higher R Value than other spray foam insulations. This helps meets the ever growing demand of building regulations required to provide energy efficient homes. the latest version offers an R Value of 4 per inch, compared to the previous of 3.7 per inch.
This R Value is enough to meet the International Code Council’s 2012 energy requirements. Builders are required to provide at least R-21 in wall cavities in order to meet the energy code 2009.
As well as this Icynene works as an open-cell polyurethane foam. This means it is water permeable and it is also water blown, making it a insulation product with the lowest global warming potential.

R Value Of Icynene vs Traditional Materials
Dependant on the brand and type of insulation available R Values will differ. The Department of Energy has provided the following information on different types of insulations available on the market.
