Insulating a Basement Ceiling

When it comes to a quick and easy way to lower your monthly utility bills, look no further than your basement ceiling. If it is not insulated, there is no better time than now to do so. Insulating your basement ceiling can drastically cut utility bills as well as give you a warmer surface to walk on (the floor on the lower level). You will also find the basement to be warmer in the winter and cooler in the summer. For anyone who knows how to work a staple gun, this a project you can do yourself!

Step 1 - Select the Insulation

The type of insulation you should use will depend on what the area you are insulating is used for. If this is an unfinished basement in North America that you wish to insulate, then an R value of 12 or more is recommended (R value is the insulation's ability to resist heat flow). For basement ceilings, batt or blanket insulation is the insulation of choice.  As for material, faced formaldehyde-free fiberglass insulation is the safest for your home, health, and the environment. Insulation can be purchased at your local home improvement retailer.

Step 2 - Measure the Area and Prepare the Insulation

Before handling fiberglass insulation, you will need to put on your gloves, face mask, and goggles. It is best to wear protective clothing as well as many people complain of itching after touching fiberglass insulation.

You will need to measure the distance between each ceiling joist. If the ceiling is broken up by wires or pipes, measure around those areas with intentions of leaving those areas exposed. Measure an equal amount of insulation and make a straight cut using a utility knife. 

With the faced side (side with the paper) touching the ceiling and the open side facing you, securely staple the insulation into place by applying staples every 3 inches. It is extremely important to lay the insulation with the proper side up. If you fail to do so, moisture will become trapped in the insulation. This will be a great breeding ground for mold, mildew, and putrid smells that you can only get rid of by completely replacing the insulation.  

Continue until all areas have been insulated.

Step 3 - Take Care of Pipes and Wires

Wedge the insulation between the ceiling and the pipes. Do the same in regards to wires.  If this is not possible, apply spray foam insulation on and around the wiring and pipes. Take care to not cover the wiring and piping to the point where access to them will be impossible. You don't want to have to insulate all over again after you do some minor pipe or electrical work.  You will now get to enjoy the benefits of using less energy, having lower utility bills, and having warmer feet in the winter when walking barefoot on the exposed flooring of the lower level of your home.
