DIY Rigid Foam Insulation

Lead Image

Probably the most attractive advantage rigid foam insulation offers is versatility. This insulation can be used in virtually any area of your home, it is structurally strong, and offers excellent resistance to heat and cold. To understand more about the properties of this insulation and why it is so versatile, read the information below.

Molded Expanded Polystyrene (MEPS)

This material is commonly used to manufacture rigid foam board insulation. This product can be manufactured in varying degrees of density, depending on its intended application. It is typically used in insulating concrete forms and insulated panels.

Extruded Expanded Polystyrene (XEPS)

XEPS typically costs more than MEPS. Its R-value can vary. It is different from MEPS in that is denser, its compressive strength is greater than MEPS, and its moisture absorbency is greater. For these reasons, it is often preferred for use on wall panels and roofs.

Polyisocyanurate (Polyiso)

This product offers higher R-Values. This allows the contractor or homeowner to install a thinner insulation board and yet get the R-value of other thicker products. It is also favored as insulation for roofs.
