Choose the Right Insulation

By June 3, 2016 No Comments

Picking the right type of insulation for your building is never easy. With so many options on the market, it can be difficult to make an informed decision. As we discussed previously, insulation is absolutely necessary if you want to keep your metal building comfortable. Today, we’ll take a look at some of the more common types of insulation to help you understand your options.


Batt insulation is typically made of fiberglass and is the most affordable and budget-friendly insulation choice. Batt insulation works best for ceilings and walls, but is only effective when installed properly. Unless you’re experienced in laying insulation, consider hiring a professional contractor. Batt insulation has an R-value (the insulating value) of R-3 per inch.

Rigid Board

Rigid board insulation can be cut to your desired thickness, giving it a range of R-values from R-4 to R-8. The board is usually made from polyurethane or fiberglass and works well in high or cathedral-style ceilings because it is so stiff. However, rigid board insulation requires additional fireproof coating in order to be up to most municipal building codes.

Spray Foam

Spray foam insulation begins as a liquid and turns into a foam once it’s sprayed on the building. The insulation expands and provides a solid barrier between your interior and the outside elements. Spray foam can be used anywhere you need insulation, from the floor to the ceiling. Once it dries, the insulation becomes air tight and does not require any additional covering to meet code. However, the foam must be sprayed in an adequate and even thickness to ensure that your building is properly insulated.


Loose-fill insulation is made up of loose cellulose fibers that are spread into the walls. The fibers often come from recycled materials that are made flame-resistant and water resistant through the manufacturing process. While it can be used in metal buildings, you’ll notice that traditional batt insulation will provide better energy efficiency. When spread correctly, loose-fill insulation has an R-value of R-3, making it a less efficient choice than other options.
