Insulation Types to Consider

September 26, 2016

Insulation Types have been discussed for the last couple of weeks, and if you follow the Capitol Machine blog, you will know that some types of insulation are better than others when it comes to the environment. Below are more types of insulation for both commercial and residential properties.

Foam Insulation affects the environment more than other insulation types because the raw materials, such as petroleum and natural gas, needs to be extracted, refined and transported depleting the ozone during manufacturing. However, some other benefits can help offset the issues including better R-values on your home because of the improved air sealing and thickness. Capitol Machine explains that foams will also save you energy over the lifetime of your home.


Also known as, Polyisocyanurate, polyiso is the most environmentally friendly types of foam insulation. A rigid foam board, it is normally backed with foil that acts as a radiant barrier or vapor. Polyiso can be used anywhere in your home and is manufactured out of nine percent or more recycled content that contains mixed color PET plastic bottles. The flame retards in the insulation are less toxic and is the preferred insulation except in damp applications and homes below grade.


EPS or expanded, and XPS, or extruded, are the two types of polystyrene. Also referred to as beadboard and blueboard there is no minimum recycled amount limit for these types of products although some may contain it, as the insulation can be recycled. Polystyrene foams pose serious environmental and health concerns because of the chemical compounds.


Expanding foam, spray polyurethane is manufactured out of a polyol and polyiso resin that may be partially soy based. Polyurethane insulation is used to fill wall cavities and requires a minimum or five percent recycled content.

Mineral Wool

Made from recycled slag, abundant rock or iron ore, mineral wool is required to contain seventy percent recycled materials, this is second to cellulose, in fact, mineral wool can go as high as 90 percent when it comes to its recycled contents.
