Rigid foams made with materials including polyisocyanurate, extruded polystyrene (XPS) and expanded polystyrene (EPS) that are valued for their insulating properties and durability. It has a higher R-Value per inch of thickness, resistant to moisture.

Variety of rigid foam insulation

Expanded Polystyrene (EPS) This is generally the best budget option for people who need rigid foam insulation. This is the same stuff your disposable coffee cup and it’s used to protect fragile items in their packaging. It provides an R-value range of around 3.6 to 4.2 per inch of thickness. EPS is used under roofing, over foundation walls and beneath siding. But if there is a risk of water exposure, invest in a moisture-resistant coating or film.

Extruded Polystyrene. This is denser than EPS and provides more R-Value with a rating of 5 per inch of thickness. Available with straight or tongue-and-groove edges to help limit air movement. It is available in all different size configurations to accommodate lots of different applications.

Polyiso (Polyisocyanurate). This is an even more dense and more expensive foam board insulation. It provides an R-value of 6 - 6.5 per inch an average of thickness and often comes foil-faced to help reflect radiant heat. It is considered an eco-friendly option when it comes to rigid foam insulation. This contains roughly 9% recycled materials. Used over house sheathing underneath siding or in attic spaces where its reflective properties are very effective.
