Homes built before 1979 usually don’t have much wall insulation. In many homes, batt insulation has been used, but it doesn’t provide complete coverage. This results in the escape of heat. Drill and fill remedies this problem because it offers total coverage. Because it’s blown in, it expands to fill every available space.

This coverage allows for the highest possible R-value for wall insulation, which is a measurement of how effective insulation is in different parts of the home. If you have an older home that already has old batt wall insulation, drill and fill techniques are ideal when it comes to re-insulating the walls and providing maximum R-value coverage. You spend less on energy bills, retain more heat in the winter and cold air in the summer, and experience higher levels of comfort with the home.

Drill and fill insulation forms a barrier that seals cracks and openings around objects leading outdoors, such as cables, pipes, basement doors, and more.

Homes without proper wall insulation experience home comfort problems, such as:

• Excessively high cooling or heating costs
• Uneven cooling and heating throughout the house
• HVAC system works over time, stressing the unit and costing you more $$$
• Walls are noticeably cold to the touch

The drill-and-fill process is an effective installation method that can be done in any home, but particularly in older homes that need to be re-insulated in the most non-invasive way possible.

Proper insulation is the top way to curb air escape from your home. Another thing you can do is seal cracks and openings to reduce drafts and cold spots, suggests Energy.gov. It’s important to prevent air leakage, which, if left unchecked, can contribute to moisture problems that can affect occupants’ health and the home’s durability.
