Insulate your attic to minimize heating and cooling costs all year round, increase comfort, minimize the stack effect, and extend the lifespan of your air conditioner and furnace. It’s one of the best ways to reduce energy waste.
According to the U.S. Department of Energy, attic insulation improvements (combined with air sealing and proper HVAC maintenance) can cut your heating and cooling energy use by 20% to 50%.
Read this before you start thinking about adding insulation to your attic. You will need to know which type of insulation to use, the R-value you want to achieve, along with other considerations such as ventilation levels, safety planning, and duct sealing.
We highly recommend speaking with a professional to perform a whole-house energy assessment (energy audit). This will save you a lot of time identifying the areas in your home that need additional air sealing and/or insulation.
Air leaks not only leak precious conditioned air, they can also result in poor indoor air quality and contribute to moisture problems. It’s important to seal air leaks before adding insulation.
Before you start any significant air sealing project, you should detect air leaks and speak with an HVAC professional about ventilation needs first.
After finding air leaks, review these attic air sealing tips:
Last but not least, seal air duct leaks. According to the EPA, the average home loses around 30% of their conditioned air through leaks in the ductwork. Even if you don’t detect any air leaks around the duct connections, it’s a good idea to insulate them anyway.
While it’s best to have a professional completely seal and insulate your air ducts, you can also DIY seal your air ducts with mastic sealant. Before you start sealing your duct connections, make sure the surface is clean and dry first. Don’t use duct tape!
For unfinished attics, there should be insulation between and over the floor joists. If your HVAC system is located in the attic, consider insulating the rafters as well.
Insulate all kneewalls (walls in the attic with space directly behind them). Don’t forget about insulating the attic hatch (access door).
If you live in a warmer climate, consider installing a radiant barrier.
A quick way to tell if you have insufficient insulation is by heading into the attic with a measuring stick and measuring the depth of your insulation. It depends on where you live, but generally if you have insulation below 5 inches, you could definitely bandit from increased insulation.
Find your location on an R-value map and table to fit your specific climate.
Watch these Vine-style videos from the U.S. Department of Energy to learn how to measure your attic insulation and other attic insulation tips:
Once you determine that your home could benefit from more attic insulation, you have two main choices: loose fill or batts/rolls.
You can mix and match the different insulation types, but if you choose the loose fill option, you’ll probably want to hire a professional since this requires a large blowing machine. You can also rent this equipment, but the effort is often not worth the savings.
