Insulating an Older Home

by | Aug 24, 2017

Older homes definitely have their charms, but proper insulation usually isn’t one of them. Sure, there are a lot of tricks you can employ to patch some common sources of heat loss—patch up weak spots in the windows or floorboards, put draft excluders under doors, place loft insulation in your attic, etc. But often the fatal flaw is much more difficult to access. Shoddy insulation hiding behind drywall is a major problem for homes of all ages and styles, but especially those built before WWII.

If you’re sick of drafty, noisy interiors and sky-high heating and cooling costs, it’s probably time to think about re-insulating your home. The good news is that, thanks to advances in insulation technology, this doesn’t have to be a major undertaking. In fact, we’re able to re-insulate most homes to modern standards within just one or two days, with no mess or fuss. Most of the time you won’t even need to move furniture!

In the past, if you wanted to re-insulate an existing home, you’d be forced to rip out your drywall, strip everything out and start anew. And in truth, if you want the absolute best insulation money can buy in terms of heat transfer resistance, that’s still true. But with RetroFoam, we are now able to provide insulation with R-values close to top-of-the-line foam products (and way, way better than fiberglass) without ripping out any drywall at all. (By the way, we also carry those top-of-the-line foam insulators too, and use them often for new construction and remodel projects.)

RetroFoam can be injected directly into the wall cavity through a tiny opening, usually on the outside rather than inside of your home. From there it fills the cavities (including around irregular obstructions) and hardens into a lightweight solid. It is a non-expanding foam, meaning it shouldn’t pose a risk of damage to interior walls, and when installed properly it can hold its size, shape, and thermal-resistance properties for the life of the home—far longer than you’d get from fiberglass.

There are other great advantages to using this product on an existing home:

  • Noise dampening
  • No maintenance
  • Environmentally friendly
  • Fire resistant
  • Inhibits insects and critters

So what are you waiting for? Don’t let winter arrive before you choose to do something about your poor insulation. Give us a call for your free estimate at (269) 751-2000.
