Is your insulation working?

Why Insulate?

Is your wall insulation working? Do you experience these common challenges with your home:

  • High Energy Bills
  • Cold or Hot Rooms
  • Uncomfortable Drafts
  • Loud Exterior Noises
  • Overworked Furnace
  • Freezing Pipes
  • Unhealthy Air Quality

If you said “YES” to one or more of these challenges, your home’s insulation needs to be updated.  Call us TODAY and let Northwest RetroFoam™ help you overcome your pesky home challenges with our innovative RetroFoam™ home insulation!

RetroFoam™ is designed specifically for insulating existing wall cavities.

Considering the total area of your outside walls, it’s not surprising that the heat loss through the walls in a typical house is greater than through the windows and floors combined. Even with an insulated ceiling and windows, the heat inside your home will find the next easiest path to escape – your walls. When insulating your home, it is important to have a holistic approach. For example, think of an icebox…if only the lid was insulated, it would not work effectively.

How RetroFoam™ Home Insulation Works

RetroFoam™ is a plastic foam containing millions of tiny air cells. Within minutes of injecting the liquid foam into the wall cavity, it sets to form a firm, resilient filling, which contains millions of tiny bubbles of still air. These pockets of trapped air minimize air circulation within the wall cavity, thereby preventing heat loss and stabilizing your home’s temperature. Once installed, RetroFoam™ home insulation will remain effective for decades.

RetroFoam™ is an extremely safe product to install into your walls. Unlike polyurethane spray foam, RetroFoam™ is a modified plastic foam, installed by a trained technician. RetroFoam™ is fully expanded prior to entering your walls. RetroFoam™ meets government guidelines, does not create a fire hazard, and has a high R-value.

Over time, loose-fill insulation products, such as fiberglass and cellulose, can shift and/or become compacted thereby allowing for greater air movement and creating an ideal spot for rodent nest building. RetroFoam™ is an innovative solution to these problems as our injection foam fills all the voids inside your walls and becomes a lightweight, solid unit of insulation, which keeps rodents out and stops air movement.

If alterations inside your wall cavities are needed after the installation of RetroFoam™ , the solid blocks of RetroFoam™ insulation can be easily removed while your project is in progress. Simply place the RetroFoam™ blocks back into the wall cavities upon completion of your wall project. If rewiring is needed, wires can be pushed through the RetroFoam™ blocks, or the RetroFoam™ blocks can be easily cut.

The Best Home Insulation Solution

RetroFoam™ insulation is a cost-effective, efficient solution to preventing energy loss in your home. Regardless of your home’s exterior material (vinyl, brick, stucco, wood, etc.), RetroFoam™ can be installed into your wall cavities from the exterior of your home. RetroFoam™ can also be installed through your home’s interior walls – a great option for condos and apartments.


According to energy.gov, an insulation’s resistance to heat flow is measured in terms of its R-value. The greater the R-value, the greater the insulation’s effectiveness. An accredited third-party lab has calculated R-values of RetroFoam™ to range between 14.5 to 23.7 depending on the thickness of the wall. By installing RetroFoam™ , you will maximize the R-value of your walls, which significantly reduces the amount of air leaks in your home. The excellent sealing qualities of RetroFoam™ result in immediate benefits AND immediate savings for you!
