Q: What are the advantages of insulating walls with polyiso continuous insulation (CI)?
A: Traditional construction practices typically place insulation between the wall framing members (wood or steel studs, commonly), which creates individual bridges for heat transfer between indoor and outdoor spaces. To mitigate this problem, building teams can employ polyiso continuous insulation (CI), which insulates the entire opaque exterior of framed walls to reduce energy losses and gains.
Additionally, with properly sealed joints, polyiso CI is available as an approved and code-complaint water-resistive barrier (WRB) and can also act as an efficient air barrier. As a result, building teams can turn to polyiso CI for its superior value and performance as a three-in-one building envelope solution that reduces energy loss, mitigates air leakage and minimizes the risk of moisture intrusion. And because of polyiso’s high R-value per inch, building teams can pack more energy savings into a thinner profile, creating more usable floor area within the footprint of the structure.
