If you live in an older house with substandard wall insulation listen to this. Proper cavity insulation is one of the simplest ways to increase your home’s energy efficiency. And it’s extremely cost effective as well. Older homes of brick or masonry can be dramatically improved by this easy and inexpensive upgrade.

About 100 years ago builders of masonry and brick projects shifted from using single-wall construction for a building’s outside walls to a stronger and sturdier two-wall configuration. These two walls would be built close together and separated by a dead air space. This air space added some insulation value, but not a lot.

There are ways to improve this situation drastically. By filling the gap (the cavity) between the two walls, efficiency can be almost doubled. One tried and true method for doing this is to drill little holes in the exterior wall and to blow in plastic beads, which will settle in and fill up the void. This will make a big improvement, to be sure, but there are better ways of accomplishing this job.

Since double-walled construction was only used on exterior walls it’s usually easy to access the surfaces needing the attention. Most everything for the job can be done from the outside of the house, causing little disruption for the building’s occupants. It also makes the upgrade straightforward, easy and quick to accomplish.

Technological advancements have made the ‘greening’ of your home easy and cost-effective. Weather proofing a home not only makes it more efficient but also more comfortable. It’s estimated that 60% of your home heating costs would be saved if you insulated your old, double-walls. It’s inexpensive to do and will end up paying for itself in a very short time.

The best method for wall insulation to date by using one of the expanding spray foams on the market. In this process, a hole is drilled in the outside wall and a liquid containing a polymer and a foaming agent is sprayed into the void. The foam expands, filling every little nook and cranny, and then dries within a few short minutes. This provides an air-tight barrier that totally seals the wall.

Nothing is better suited for this application. Cavity insulation is complete when the foam dries, which only takes a matter of minutes. The dried material will not shrink, sag or settle. Your property will become more comfortable and ‘green’. It’s a win/win!
