Millions of houses built in the 1980s were constructed with almost no exterior wall insulation at all, leading to extremely high winter heating costs, cold interior wall surfaces, and frequent mold growth issues on interior walls. The EPS Cement Sandwich Panel is one of the most effective non intrusive ways to fix this problem during an old house renovation project, as you can install the full panel system directly onto the exterior of the existing old masonry walls without having to demolish or modify the original interior wall finishes. The panel system adds a full continuous thermal insulation layer across the entire exterior wall, completely eliminating the cold wall surfaces that cause condensation and mold growth inside the old home. This simple upgrade can reduce the home’s annual heating energy consumption by as much as 50%, which pays back the full cost of the renovation in just a few years through lower utility bills. Unlike external insulation systems that leave you with a soft, fragile exposed insulation layer, the EPS Cement Sandwich Panel comes with its own durable cement facing that acts as the finished exterior base for your new render or paint finish. This turns a messy multi step insulation upgrade project into a single fast installation process that causes very little disruption to the homeowners.
