Boy how things change. Fuel is expensive and only getting more so. Utility bills are on the rise. Building owners are constantly on the hunt for money- and energy-savings. Knowledge and research have taught us that R-values alone aren’t enough when it comes to insulation. And, of course, advances in technology have given us many more insulation options.
Fiberglass. Mineral Wool. Injection Foam. Cellulose. Spray Foam. Cotton Batts (aka blue jeans). With so many more options, selecting an insulation that will deliver the most energy savings can be a challenge. To make the decision easier, a lot of people buy based on R-value alone. Which is a huge mistake because R-value alone doesn’t tell the whole story about how insulation works.
That’s why R-value is the biggest insulation urban legend.
• Adding insulation that doesn’t control air leakage can be a waste of time and money.
(Read this and this to find out how)
• Increasing R-value levels, beyond a certain point, delivers diminishing savings
• R-value can be reduced by as much as 50% after install
• Investing in too much insulation may cost you more than it saves
Lessons learned: a higher R-value isn’t always a good thing, and shouldn’t be the determining factor for choosing one type of insulation over another. Best to determine what your specific needs are and look at the pros and cons of each insulation option. The best insulation for your particular project should pay for itself right away, and help improve your building’s health, comfort and resale value.
