Garage Ceiling Insulation Guide

If you have an unfinished garage ceiling and a room above the garage, you may want to consider adding insulation to your garage ceiling in order to reduce the amount of energy that is lost between the room and the garage ceiling. The garage ceiling tends to lose quite a bit of heat over the winter months because of the constant opening and closing of your garage doors when you let your car in and pull it out from the garage. Below are several things that you should keep in mind when you install your garage ceiling.

Safety Precautions

Whenever you are working around insulation, you should always make sure you adhere to proper safety precautions. This means that you should always put on and wear a face mask or respirator to protect your lungs from the particles that float around from disturbing the insulation and this also means that you should wear protective gloves to protect your hands.

Ceiling Insulation - Unfaced Batt

As you prepare to add unfaced batt insulation to your garage ceiling, you need to make sure the following is taken care of during insulation installation:

  • The batts of insulation must fit properly over the ceiling. This means that you must make sure the bats of insulation run from one end of the ceiling to the other, without gaps.
  • Never double the insulation. Cut to size, if needed.
  • Cut the bats of insulation so that they properly fit around electrical and plumbing components.
  • You must maintain ventilation in your garage (for example: around all eaves and soffit vents).

Ceiling Insulation - Faced Batt

If you are instead installing a faced batt type of insulation, in addition to the requirements that need to be met as discussed in the unfaced batt section of this article, you must keep the following additional components in mind as well:

  • Always place the face towards the living spaces (i.e., towards the room that may be over the garage).
  • Staple each batt of insulation in place. Use staples every 8 inches or so.
  • Do not tear the facing, wherever possible.

Blown in Insulation

You may also opt to blow in the insulation into your garage ceiling. If this is your method of choice, remember the following crucial points:

  • Maintain all ventilation in the garage. Do not block the air space.
  • Blow the insulation in uniformly. The thickness of the insulation should be similar throughout the area covered.

Materials Purchased

When you head to the local home improvement center and purchase your insulation, make sure that the insulation conforms and complies with the Uniform Building cCde (enacted in 1997). Refer to section 707 for the particular information regarding insulation material compliance. This is required in order to meet the necessary fire codes.

Manufacturer Specifications

Check the specifications outlined by the manufacturer for their required guidelines and information for installing the insulation in the ceiling above your garage space. Make sure you go through their recommended steps before you begin this project.
