Closed cell spray foam vs. rigid foam board – Thermal performance & more
The use of closed cell density spray foam insulation vs. rigid foam board in exterior continuous insulation applications provides architectural firms and commercial building contractors a great opportunity to positively impact their building schedules, budget and overall performance quality.
Icynene’s latest white paper “The Performance Benefits of using Medium Density Spray Foam in Continuous Insulation Applications” highlights that medium density, closed cell spray foam:
- Meets or exceeds thermal performance of comparable rigid foam insulation products due to its high R-value*, which can also lead to reductions in overall wall thicknesses
- Creates a continuous insulation, water resistive barrier and air barrier layer in one step
- Delivers consistent system performance for cost and construction schedule savings
- Can cover the widest range of exposed surfaces to prevent thermal bridging
- Features an approach to air and water resistive barrier creation that is not dependent on extensive use of joint sealants in exposed situations
- Has a much better ability to bond to the entire length of wall penetrations, such as brick ties and fasteners, thereby better ensuring thermal and airtightness effectiveness
- Is less likely to have air barrier discontinuity at transitions and control joints
- Has very low water absorption and is capable of shedding water
- Can be applied in cold temperatures as low as 5ºF (for Icynene ProSeal Eco)
- Can be installed in wall assemblies that are fire-rated or part of non-combustible construction

* R means resistance to heat flow. The higher the R-value, the greater the insulating power. Compare insulation R-values before you buy. There are other factors to consider. The amount of insulation you need depends mainly on the climate you live in. Also, your fuel savings from insulation will depend upon the climate, the type and size of your house, the amount of insulation already in your house, and your fuel use patterns and family size. If you buy too much insulation, it will cost you more than what you'll save on fuel. To get the marked R-value, it is essential that this insulation be installed properly.
