How to Insulate Water Pipes in an Unheated Garage

Insulating water pipes prevents freezing.

Hot water pipes lose a small amount of energy if they are not insulated properly. The problem is greater for water pipes in an unheated part of the house or garage. Not only are pipes without insulation wasteful, they are also in danger of bursting when the temperature drops below freezing outside. Insulating pipes does not cost a lot of money and takes no expert skill. You can insulate pipes in your garage in less than an hour.

Things You'll Need

• Measuring tape
• Scissors
• Foam insulation

Instructions

1. Measure the length of the pipe using a measuring tape.

2. Cut the insulating foam to the correct size.

3. Slide the pipe through the premade slit in the foam insulation.

4. Peel off the backing paper to expose the insulation adhesive in the slit.

5. Press the slit together to bind the two sides around the pipe.

Tips & Warnings

• Seal holes around the garage using silicon caulk to prevent air from rushing into the garage.
