Above Grade Walls

There are many ways to improve the energy efficiency of your home from the inside, but there are a couple of exterior renovations that we did on the Revitalize Home that deliver real results.

  • Insulate above grade walls while residing
  • Insulate foundation walls

Insulating Above Grade Walls While Residing

Residing is a great opportunity to increase a home’s value with a fresh, new look. It’s also the perfect time to increase energy efficiency and overall comfort with durable STYROFOAM™ Brand Insulation that:

  • Maintains thermal performance – up to R-5.0 per inch to pay back initial investment fast
  • Provides an even, level surface for new siding
  • Resists moisture
  • Serves as a drainage plane

One inch of STYROFOAM™ Brand Tongue & Groove Insulation was used on the Revitalize Home prior to adding Ply Gem siding, contributing to a better performing – and better looking – exterior.

As the table below shows, using thicker insulation provides a faster payback!

As part of any residing project, it’s also important to include:


Insulating Foundation Walls

In addition to energy loss that leads to higher energy bills, uninsulated exterior walls can result in condensation on cool basement wall surfaces. It’s a good idea to insulate the exterior foundation to keep basement walls warm and reduce the potential for moisture problems that can lead to mold and mildew.

STYROFOAM™ Brand PERIMATE™ Insulation was installed around the Revitalize Home exterior foundation to provide a continuous layer of thermal protection. Its grooves assist water drainage away from the foundation, providing your walls with:

  • Long-term thermal performance
  • Exceptional moisture resistance
  • Added compressive strength to resist soil and hydrostatic pressures

Nudo® Ground Breaker ® Foundation & Insulation Barrier can be used to cover exposed rigid foam insulation
