When specifying rigid foam insulation panels for a construction project or remodel, professional builders and architects have an effective, durable and cost-effective option with EPS. High quality EPS wall insulation can be used on the inside and outside of the foundations. Rigid foam insulation panels can also be used on the outside of wall framing or between studs. Once delivered on site, the EPSs panels can provide easy-to-handle insulation throughout your site. Choose un-faced or laminated with a poly vapour barrier or OSB panel.
