The garage can be an unpleasant workshop during months with extreme heat or bitter cold. Here are some ways to temperature proof your garage so it will be a more enjoyable work space all year round:
Insulate the garage walls and install a moisture barrier over the insulation. Cover the moisture barrier with wallboard to be extra insulated. Picture from Family Handy Man.
Insulate the windows and doors by caulking the frames and using spray foam insulation for particularly large spaces. Install weatherstripping and sweeps to the bottom of the doors, including and especially the big overhead doors. (I recently wrote an article on insulating your garage door that has all the details on how to do it yourself). Idea from HGTV.
Install a Ceiling
Also install a hutch door if you want to access the attic portion of the garage. Insulate the ceiling as well. To learn how to install your own drop-down attic ladder visit doityourself.com
Paint the Floor
Paint the concrete floor with an epoxy concrete paint to keep ground moisture out.
Light Colored Garage Door
To keep the garage cool, make sure the door is painted a light color on the outside so it will reflect heat.
Install ventilation sources like free-standing fans, wall fans, and ceiling fans. The fans should be placed so that they push hot air out of an open door or window, and generate cool air on the opposite side. Image found here.
