While there are many types of flat roof insulation available, here are how the three most common types compare. ![flat roof insulation](https://info.firstqualityroof.com/hs-fs/hubfs/flat%20roof%20insulation.jpg?width=695&height=463&name=flat%20roof%20insulation.jpg)   ### **Rigid Foam Insulation ** Made from rigid sheets of polyisocyanurate or polystyrene foam, rigid foam insulation features an R-value that ranges from 4.6 to 6.8 per inch of thickness, depending on the product. It is relatively easy to install and offers excellent thermal efficiency, but it can also be quite costly. It is ideal for areas that need a bit more rigidity and structural support than other types of insulation. ### **Spray Foam Insulation** Installed as a liquid that is sprayed between the rafters or purlins, polyurethane spray foam insulation will adhere to adjoining surfaces as it expands and cures. It works well as[flat roof](https://info.firstqualityroof.com/blog/guide-to-flat-roof-repairs-tips-for-a-sturdy-overhead-roof) insulation because it insulates and seals in one step, plus it fills any gaps or voids in the roofing system. It features an R-value that ranges from 6 to 7, depending on the brand and product.[Spray foam](https://info.firstqualityroof.com/blog/fiberglass-vs.-spray-foam-insulation-in-las-vegas) can be quite expensive, however, and to ensure it installs and cures correctly, with no dangerous fumes, it must be installed by a highly experienced professional. ### **Fiberglass Insulation** Made from layered strands of glass,[fiberglass insulation](https://info.firstqualityroof.com/blog/whats-better-cellulose-vs.-fiberglass-blown-in-insulation) offers good thermal performance, and it is quite economical. Available in batts that can be easily installed between rafters or as a blown-in product that is professionally installed, fiberglass offers up to an R-6 rating per inch of thickness, and it is resistant to moisture, mold, and pests. Though it has a lower R-value than foam products, it is easy to install, and it provides excellent value for the price. ### **Choosing Your Flat Roof Insulation** Your choice of flat roof insulation will depend on the roofing materials you use, the design of the roof, and your available budget. Fiberglass is the most budget-friendly option, and it can be installed in virtually any type of roof, but rigid foam offers higher thermal performance to go along with its premium price. Spray foam offers additional air sealing and waterproofing capabilities, though it is the most costly of all the options. ## **Flat Roof Insulation Services in Las Vegas** If you need high-performance insulation for your flat roof, turn to our experts at First Quality Roofing & Insulation.
