Insulation

McGuire R-Guard Polyiso insulation is a highly effective thermal insulation material widely used in commercial roofing applications. Made from polyisocyanurate foam, this insulation boasts a high R-value per inch, meaning it provides excellent thermal resistance while maintaining a lightweight profile. Its rigid board design allows for easy installation and can be used in various roofing systems, including flat, low-slope, and steep-slope roofs. Additionally, McGuire R-Guard Polyiso insulation has a vapor barrier and moisture-resistant properties, helping to prevent water intrusion and mold growth, ultimately enhancing the longevity and energy efficiency of the building.

Frequently Asked Questions

What are the benefits of using McGuire™ Polyiso insulation in commercial roofing systems?

McGuire™ Polyiso insulation provides high thermal resistance, lightweight performance, and excellent energy efficiency for commercial roofing applications. Its rigid board design helps improve building insulation performance while supporting long-term roof system durability and thermal protection.

McGuire™ Tapered Polyiso Foam Insulation is commonly used to create positive roof drainage on low-slope commercial roofs. By directing water toward drains and reducing ponding water, tapered insulation can help improve roof performance and extend the lifespan of the roofing system.

McGuire™ EPS insulation is a lightweight, closed-cell expanded polystyrene insulation designed for commercial roofing applications. It offers strong thermal performance and can be used in a variety of roofing assemblies where energy efficiency and insulation value are important project requirements.

McGuire™ Flute Filler is engineered to fill the gaps within metal roof deck flutes, creating a stable surface for insulation and roofing system installation. This helps improve system support, thermal performance, and overall roofing assembly efficiency.

Commercial roofing insulation helps improve energy efficiency, reduce heat transfer, enhance indoor comfort, and support long-term building performance. Proper insulation selection can also contribute to lower energy costs, improved moisture control, and increased roof system longevity.
