Protect Against Air Loss and Block out Sound With Easy-to-Install Foam Insulation

Duct tape may be lauded as the home improvement product that can fix anything, but we’d like to make an addendum. Duct tape and foam insulation are the two home improvement products that can fix everything. Affordable, durable and long-lasting, foam insulation should be on every workbench, inside every kitchen drawer, and next to any air conditioner unit in your home or office.

Foam insulation is commonly used to fix drafts around doors, windows and expansion joints. Often sold in long strips with tape on one side, foam insulation is simple to tape around areas that have cracks and holes that are letting air escape and costing you a fortune in heating and cooling costs. Designed to resist mold and mildew, foam insulation is ideal for use in areas where it will be exposed to water.

Foam insulation is also a great product to use to help soundproof areas, with many people applying the foam around doors, windows and on the walls in recording studios, home theatres and even nurseries. Crafters, hobbyists, and anyone tired of hearing their small appliances scrape on the floor or counter can use foam insulation as padding.

If you’re got a problem around the home, there’s a good chance foam insulation can help solve it. Check out our top picks below.

1. Frost King Rubber Foam Weather Seal

For insulation with major staying power, we recommend the Frost King Rubber Foam Weather Seal. The Frost King has an impressive five-year lifespan starting at application, helping to insulate against air loss. The 10’ long black foam tape is 1/2” wide and 9/16” tall and comes in nine size options to fit any job. The flexible foam can fit and fill small cracks and holes. The compression tape can seal in windows and doors, eliminating air loss from drafts. It’s also shock-absorbing and durable and can be used around appliances like air-conditioner units.

Pros: The Frost King is a great option for cars, trucks and boats that need insulation to help stop rattles, squeaks and vibrations.

Cons: The Frost King has a shorter lifespan if used in areas that are constantly in motion.
