This method will greatly increase comfort levels in summer and winter, though it may reduce headroom. We've curated below the most common questions asked about our top rigid insulation choices: THERMAX Polyiso Insulation and STYROFOAM XPS Insulation.With increased attention on resiliency and building code requirements of late, the most asked topics are about mildew, flame spread requirements, and how to material storage. STYROFOAM. Next, press the rigid foam board into place on the foundation wall. It is lightweight, easy to install, and highly effective compared to other forms of insulation. Line up the first furring strip on the bottom chalk line. You will know whether the rigid foam insulation needs a vapor barrier depending on how it is installed. If more than one layer of foam is used, the exterior layer of the foam is the water control layer and all seams in that layer should be taped with appropriate foam-compatible tape. A. Insects are capable of squeezing through very small cracks and seams. Install a continuous air control membrane (house wrap or paint-on membrane) over the existing sheathing as shown in Figure 1. Knowing there is one opportunity to optimize performance during construction, wouldnt you agree its a great opportunity to meet or exceed future codes? Remove the existing wall cladding and trim, and inspect the structural integrity of the wall. He'll take out his lighter and show you.) Installing storm windows also decreased heat-loss by 11%. However, for basement walls, closed-cell foam spray is the better option to use with rigid foam boards. Right Some tape is pressure sensitive; a roller is used to apply even pressure to ensure full adhesion. High-Performance Fenestration & Insulation. Repeat to cover the entire wall or ceiling. Watch out: depending on whether or not the foil backing on the existing foil-backed gypsum board is perforated or not, the perm rating of that surface could be near zero - that is, very resistant to moisture movement, forming a moisture barrier in the "wrong place". This type of rigid foam board is manufactured by expanding spherical beads in a mold. It is lightweight, easy to install, and highly effective compared to other forms of insulation. They are also employed in insulating constructions to cover up flaws, cracks, and gaps in walls . Building codes restrict the use of unprotected foam in habitable or accessible spaces. Section R703 Exterior covering. The following exceptions apply: air barriers recommended, but not required, in adiabatic walls in multifamily dwellings; and, in Climate Zones 4 through 8, an air barrier at the interior vertical surface of insulation is recommended but not required in basement walls or crawlspace walls. 10. So, rigid foam insulation can be applied wherever thermal protection is needed. This rating is low but can work in several spaces where you only need a base level of insulation. Like Reply Raye Mac 10 months ago I really needed to know this! What this means to you is less wasted energy along with enhanced comfort and quiet.
