Polyiso Roof Insulation

Insulation is one of the most critical components of a roof, providing much needed thermal performance in today's energy-conscious world. Polyiso's unique benefits, strength and versatility allow it to adapt to a variety of roofing applications. Polyiso provides:

  • High R-value per inch

  • Outstanding installed cost advantages

  • Only roof insulation with third-party certification of thermal performance

  • Only high-thermal foam to meet both FM 4450 and UL 1256

  • Nationwide availability

Polyiso Wall Insulation – Commercial Construction

More builders are choosing Polyiso insulation for use on and in walls. Because Polyiso foil-faced insulation has one of the highest R-value per inch, the U-value of the cavity wall system can be achieved with minimum thickness, which decreases the overall footprint of the building and lowers construction costs. In cavity walls, Polyiso's foil face and R-value allow increased air space between inner and outer wythes to more efficiently divert water to the outside and improve long term thermal performance.

Polyiso Sheathing Insulation – Residential Construction

According to the Department of Energy, heating and cooling costs comprise more than 44 percent of the energy consumed in a single family home. As many design professionals are aware, choosing energy-efficient insulation can be one of the most effective ways to save energy and money.

Typically, Polyiso is used to insulate an entire wall, including the framing. Framing usually accounts for at least 20 percent of the total wall area and is often left uninsulated. By insulating the entire wall, you can effectively reduce heat loss through both convection and conduction. And by properly insulating a structure with Polyiso, you can decrease condensation in walls which could potentially lower your moisture-related problems.

When properly specified and installed, Polyiso sheathing insulation offers one of the best values available for residential construction. Benefits include:

  • A residential wall system with a high R-value, which increases the energy efficiency of the home and significantly reduces heat loss.

  • A reduction in air infiltration and exfiltration, which increases the overall performance of the wall and reduces heat loss.

  • A reduction in the risk of water condensation/intrusion, which increases thermal and structural performance and reduces builder call backs.

  • Insulation over the entire framing members which reduces the overall home energy loss.

  • Increased home builder confidence with an assurance the builder is providing a quality product.

  • More confidence that your home was built with state-of-the-art energy-efficient techniques.

Since the 1970s, studies conducted by the EPA's Energy Star Homes Program have consistently concluded energy-efficient homes earn higher resale prices than average homes, and are less expensive to heat and cool.
