Upcycled and renewable materials are gaining popularity as insulation materials, including denim, rigid cork and natural wool. But most roofing projects will feature one of these three common insulation types.
Batt and blanket insulations
These flexible insulation products come in pieces (batts) or rolls (blankets). They include popular insulation products like fiberglass and mineral wool.
Rigid foam board insulation
Like the name implies, these are rigid pieces of insulation that are cut into board shapes or, in some cases, molded into the shape needed for a special application. Common insulation types for rigid foam board insulation include extruded polystyrene insulation (XPS), expanded polystyrene (EPS) and polyisocyanurate, a type of insulation made of rigid foam board sandwiched between two facers, such as paper and fiberglass.

Spray polyurethane foam insulation goes on in a liquid form and expands to fill the area where it’s applied. Spray polyurethane foam is useful for creating continuous insulation with no holes or leaks.
“The best insulation material for your facility is going to boil down to code requirements and climate zones,” explains Tom Robertson, business unit manager for wall insulation at Atlas Roofing Corporation.
“As you need more R-value on your building, you have to start thinking, ‘If I keep putting thicker and thicker insulation onto these buildings in New England, what does that mean for the claddings that I have to attach after I attach that insulation?’ It means they move further and further from the structural framework of the building, so they’re harder to install with all that weight hanging further outbound of the building itself. People have a preference for insulation with higher R-values per inch as you move north specifically for that reason,” says Robertson.
How to Find the Best Insulation Material
Choosing the best insulation material for your building requires an understanding of the role you need the insulation to play. The R-value of the finished assembly is the most important, but the decision around R-value can manifest itself in different ways.
“The various types of insulation have widely ranging R-values,” says Robertson. “That’s usually a matter of cost, or it might be a matter of how much insulation I want to buy. If I have an R-value target, do I use a less expensive insulation and more of it, or do I use a more expensive insulation and less of it?”
