Installing Batt Insulation in a Ceiling

Batt insulation can help you enhance the energy efficiency of your home. The insulation is made of fiberglass which is one of the most effective and inexpensive insulation options available on the market. Properly installed batts in the ceiling can help to reduce the energy required to heat and cool your home. This gives you significant savings on energy costs. Batts come in different sizes and R-values. The R-value refers to the energy efficiency properties. In most cases, an R-value of 30 to 38 is suitable for ceilings. The guide below shows you how to install batts in the ceiling.

Tools and Materials Needed:

  • Batt insulation
  • Measuring tape
  • Utility knife
  • Insulation poker
  • Knee board
  • Gloves
  • Safety goggles
  • Dust mask
  • Respirator
  • Step ladder
  • Long handled broom
  • Halogen work light

Step 1 – Take Measurements

Use a measuring tape to obtain measurements of the ceiling area that you want to insulate. This will help you determine how many bales of batt to purchase for installation.

Step 2 – Clean the Roof

Locate the ceiling manhole and mount the step ladder to get into the roof. You’re likely to find cobwebs and dust in the roof area. These tend to accumulate with time. A heavy presence of these can create difficulties for you during installation. Use a long handled broom to clear away as much of the dirt as you can. It is best to allow about 30 minutes for the air to clear before you proceed with the project.

Step 3 – Carry Batt Insulation into Roof

Take all the bales of insulation, one by one into the roof area. Wait until you’re ready to install before you open any of the bales. Once released from the packaging, the fiberglass expands considerably and it can be quite a task to contain it.

Step 4 – Protective Wear

Before you embark on batt installation, be sure to wear some protective items. A long sleeved shirt and gloves will help to protect your skin from irritation by fiberglass. Safety goggles are an excellent protective measure for the eyes. Wear a respirator to prevent inhalation of fiberglass material which can cause you respiratory complications.

Step 5 – Installation

Install a halogen work light in a central location within the roof area. This will provide adequate illumination to enable you work effectively. Place a sturdy knee board over 2 or more joists to support you as you work. It is best to begin installation at the furthest point from the manhole. Open one package of insulation and remove some insulation. Firmly stuff the insulation between the joists of the section you’ve started on. Use an insulation poker to place the batt securely in place. Cut the batt panel to size with your utility knife if it is too large. Avoid gaps during placement as they reduce energy efficiency in the ceiling. Once you complete one section, proceed to another until you’ve installed insulation in the entire ceiling.

Step 6 – Light Fixtures and Vents

It is important that you do not cover these features. Use a utility knife to cut insulation to shape around light fixtures, vents and chimney flues. A 3 inch gap is sufficient.
