Ways to Improve Insulation

If you live in an older home, you know what it’s like to feel a nice draft. While it may be welcome sometimes, it actually means that your home is poorly insulated.

All homes, regardless of age, need proper insulation. It not only keeps your home at a consistent temperature, but it helps prevent the overuse of your heating and cooling systems. Without insulation, your unit would be running constantly, costing you a fortune, and never providing real comfort.

Therefore, we’ve put together a few tips on improving insulation in your home that doesn’t require ripping open the walls.


Weatherstripping involves placing thin strips of insulating material around doors, windows, and other openings. Often felt, rubber or vinyl, weatherstripping can be found at any home improvement store.

You can simply apply the material around spaces where you feel a draft. Just make sure to measure the size of the space, as the material will come in different thicknesses and widths.

You can also use a door sweep, essentially a large weatherstripping device, on the bottom of your doors to seal the opening with the ground.

Sealing Cracks

Another important safeguard against air leaks is sealing any cracks around windows and doors. Sometimes this involves replacing or repairing door frames and window sills. Other times, it can be as simple as applying fresh caulking to seal a crack in the wall.

Caulking can also be found at home stores. Just make sure to look for a product for the proper application, usually window and door seals. Apply the product according to the manufacturer’s instructions to the areas that need to be sealed.
