Commercial Rigid Insulation Contractors

Applying commercial rigid insulation is an effective strategy for protecting your business from Mother Nature’s highs and lows. When it’s cold outside, insulation will keep the heat in, and when it’s hot, it will keep your building from heating up. Our commercial rigid insulation contractors have decades of experience installing rigid foam panel insulation to healthcare facilities, commercial office buildings, government buildings, stadiums, retail centers and more.

Types of Rigid Foam Board Insulation We Offer

Our commercial rigid insulation contractors can install a wide range of insulation options, including:

  • Polyisocyanurate: This thermoset plastic is rated at R-6 to R-6.5 per inch. It is ideal for use in moderate climates where the temperature doesn’t get below 15 degrees Celsius. Ideally, it is applied as part of a built-up roofing system but can also be applied as part of a single-ply system or a modified bitumen system. Polyisocyanurate foam panels are manufactured with a foil layer on both sides, which helps keep the gases within the panels and preserve your structure’s indoor air quality.
  • Extruded polystyrene: Also called XPS, this is rated at R-5 per inch. Ideal for use in above-grade applications, the thicker it is, the more protection it provides. One key thing to remember about XPS is that it must be applied with a reliable moisture barrier to ensure proper performance and preserve the insulation’s thermal protection.
  • Expanded polystyrene: Rated at R-4 per inch, EPS foam insulation is a closed-cell foam insulation that offers reliable protection. While it is permeable to air and moisture, the composition also means it is more breathable and will dry out quickly.

Understanding Semi-Rigid and Rigid Foam Insulation

Semi-rigid foam insulation has a high-density insulation product. It is denser than fiberglass or mineral wool insulation and provides superior thermal protection. It is most often used behind spandrel glass panels to enhance its R-value and strengthen the building’s exterior energy envelope.

Like semi-rigid insulation in function, rigid foam insulation is composed of either expanded/extruded polystyrene board or polyisocyanurate board insulation. It is most often applied to concrete block walls or freezer/refrigeration units.

Both semi-rigid and rigid foam insulation provide considerable thermal protection for commercial businesses. Our commercial rigid insulation contractors can help you determine which is best for your business. This may mean using multiple types of insulation to account for the building’s unique design, climate and use.
