|PIMA releases technical bulletin on continuous insulation systems in walls December 20, 2011|
WASHINGTON, D.C. –The Polyisocyanurate Insulation Manufacturers Association (PIMA) has released a new technical bulletin titled “Continuous Insulation Using Polyiso Wall Sheathing: What it is, what it does and why you need it.” The bulletin outlines best building practices when using polyiso insulation in a continuous insulation system for commercial walls.
In both residential and commercial construction, continuous insulation (ci) – wrapping the exterior wall in a continuous layer of rigid foam insulation around the studs and the cavity – offers one of the best ways to block thermal bridging. It also results in walls with a higher R-value than using batt insulation alone. The benefits of continuous insulation include a reduction in heat loss, prevention of mold and mildew accumulation in the wall and better protection against water intrusion.
“National model energy codes are advancing the way we approach building commercial and residential exterior walls by emphasizing the use of continuous insulation systems,” said Jared Blum, President of PIMA. “Building-science experts have known for some time that continuous insulation is a very effective way to insulate building envelopes for energy savings. Now, modern building codes are putting this knowledge into practice.”
Polyiso insulation, when used for continuous insulation on exterior wall assemblies, offers many advantages including:
