Garages are often not very well insulated and improving this will not only save you some cash on your monthly energy bill but also keep your garage at a more pleasant temperature during cold winter months. Insulating your garage can be done in a few easy steps. Read below how you can DIY!
- Clear the walls and check for cracks and gaps
- Fill up gaps and cracks
- Install the insulation and apply the drywall
Clear the walls and check for cracks and gaps
The first step is removing the current walls covers which are often drywall. After this is done, make sure to check for mold and other potential problems as this will be hard to fix when the insulation is placed. Also, check for cracks and gaps in the outer wall and whether the windows and doors close properly. No matter how well insulated your garage is, when there are cracks and gaps or windows and outside doors that do not close properly it will still get chilly in the winter months.
Fill up gaps and cracks
The best way to fill-up gaps and cracks is with expanding foam. Make sure to shake properly before applying and hold the can upside down when spraying. Do not fill the gap completely as the foam will still expand. The foam will normally be completely expanded in 15 minutes and fully dry in 8 hours.
Install the insulation and apply the drywall
When placing the fiberglass insulation, make sure that you will keep access to the beams of the wall as these will be used to place the drywall. Use the side of the beams to connect the insulation by stapling it all the way down to the stud. Make sure that you cut the fiberglass the right size as you want to cover up every corner. After completely filling up the wall, close the wall again with drywall and make sure to not leave any fiberglass exposed as this is highly flammable.
