Fibreglass insulation

Share this project

Overall, the most favoured DIY insulation product on the market is fibreglass batt insulation. It has been around for over 80 years and continues to provide excellent R-value results. With the pros of not shrinking, settling, burning or attracting animals or insects, fibreglass batt insulation is also mould and mildew resistant, and an inexpensive option for homeowners.

Although installation may look easy, it has to be done correctly or can lead to a decreased R-value. Fibreglass comes in pre-cut sizes that fit between the standard widths of studs, rafters and joists and is available in various R-values.

If you’re insulating a wall, choose the batt designed for 2″ x 4″, then your desired R-value. If unsure, purchase the highest R-value you can afford. It can be confusing trying to find the right fibreglass insulation for your specific needs. Our insulation specialists can explain your options and help you choose the right fibreglass insulation for your home.

Pro tip: the best way to cut fibreglass insulation batts

It’s important to cut fibreglass insulation in straight clean lines to ensure a snug fit without gaps. Use a straight edge, like a 2×4 or scrap plywood, that is longer than the width of the insulation batt. Lay the insulation on the floor with plywood underneath so you don’t damage the floor surface. Lay the straight edge across the batt on the cut line. Compress the insulation by kneeling on one end of your straight edge and hold down the other end with your hand. Use a sharp utility knife to make the cut in a single stroke.
