Properly insulating your basement can keep it comfortable all year long. Your basement can be notorious as the coldest room in your house. However, you can stop that by properly insulating it against all of the weather fluctuation outside. With the correct insulation, your basement can stay warmer in the winter by keeping the cold from penetrating your basement walls, and cooler in the summer by adding a layer between you and the hot air outside. This will help lower your heating and cooling costs and save you energy.
How to Insulate Your Basement
Things to Remember Before Starting
- Always ensure that your installation is as clear and accessible as possible. You’ll need to be able to move around easily and access all required areas.
- You’ll need some basic tools to help complete your project. Having a hammer, putty knife, caulking gun, tape measure, straight edge, utility knife, a lightweight stapler and a pole or rake (for hard to reach places) will help make this job a lot easier.
- Lastly, remember that when you open a package of batting, it will expand significantly, so try not to open it outside of your project area.
Build a standard wall frame using studs around your basement and place them against the concrete wall. Space your studs either 16” or 24” apart. This will allow you to cut your batts to fit comfortably between them.
Place the batts between the studs ensuring that they’re level with the face of the studs and not pressed in too deep. Make sure to cover the band joists, as a lot of heat loss can occur there.
Once the studs are up and the insulation has been stuffed in place, add a vapour barrier over top of the whole thing, making sure to overlap joists by 6” and seal with a caulking or tape. Then simply apply your drywall over top.
