The Best Insulation for Your Home


The most commonly known insulation materials, such as fiberglass, rockwool or cellulose, are not necessarily the best options for your home. Sure, these insulation materials have been around for awhile, so they’ve had time to earn their acclaim. However, there’s a new kid on the block – injection foam insulation – that’s garnering accolades and is sure to be a mainstay on home improvement and new build jobs alike.

What is injection foam insulation?

Here’s the complicated version of what injection foam insulation is:

Constructed from phenolic-based methylene-linked synthetic polymer, the aqueous resin solution and the foaming catalyst are ratioed together using compressed air. The result is a material that has a consistency like shaving cream and can be pumped into walls, where it hardens.

Here’s the simple version:

The unique make-up of this insulation allows it to be pumped into walls in a liquid state. As it makes its way in between wall studs, it moves over plumbing pipes and electrical wires. Within about a minute – giving the injection foam time to cover every square inch – the material will harden. At that point, it creates an airtight insulation layer.

What’s the big deal?

Injection foam insulation really is a big deal. Take a look at how it measures up once it’s installed.

  • Higher insulation properties. Compared to cellulose, fiberglass and rockwool, injection foam insulation can rate as much as 35 percent higher on insulating values.
  • Lower utility bills. Because injection foam insulation scores a high R-value, it’ll keep heated and cooled air inside and drive energy bills down as a result.
  • Better comfort. When your home benefits from more heated and cooled air (and less energy loss), you’ll feel a world of difference in terms of your comfort level.
  • Less noise. Bothered by street noise? Can you hear your neighbor’s A/C? You won’t worry about noise when your walls are insulated with soundproofing injection foam insulation.
  • Improved indoor air quality. Because injection foam hardens, your home won’t be subject to chemically-treated fibers floating around in the air or clumps of loose insulation being released.
  • Seamless installation. If you’ve wondered how installers get insulation inside walls, wonder no more! The best companies employ a seamless process that doesn’t require tearing down walls and leaves little or no evidence that the job was even done.
  • Top-notch fire and smoke ratings. The insulation scores high marks for its insulating capabilities, but it can also slow the spread of fire. Look for a product that is a Class 1-rated material, doesn’t emit hazardous gases when exposed to fire or heat, and maintains that rating over its lifetime.

The best insulation for your home is the one that meets the highest expectations for a comfortable, energy-efficient home.
