Exterior Walls - Residing

Now that you are considering residing your home, there is no better time to consider upgrading your insulation. STYROFOAM™ extruded polystyrene insulation under your new siding can help cut your heating and cooling bills, and help save money from now on. It's a smart investment that will pay for itself within the first few years and will continue paying back for the lifetime of the home. Wood framing (studs, window and door framing, and headers) make up about 25% of the wall surface. Insulating only the cavities means 25% of the wall surface is left uninsulated. A continuous layer of STYROFOAM extruded polystyrene insulation installed over old siding or directly to studs reduces energy loss. And, it can reduce the potential for condensation and resulting moisture problems in your walls.

There is a STYROFOAM insulation solution that is right for every Exterior Existing Wall application:
