Insulating Your Metal Garage Door In 3 Basic DIY Steps

Posted on

Metal garage doors are definitely a homeowner preference for a lot of reasons. These doors are resilient, lightweight, and overall function well for the purpose. However great garage doors made from lighter weight metal may be, these doors are also not always insulated, which can introduce a new problem: a chilled or heated garage depending on the season. Thankfully, having a basic metal garage door does not mean you have to put up with freezing your toes off in the winter or battling the heat in the summer. There are three basic steps you can follow on your own to insulate your metal garage door and at least combat some of the problem. 

Add an insulated door stop along the floor at the base of the garage door. 

If you are like most homeowners, the stop at the base of the garage door along the floor is just a thin piece of rubber. However, this one thin piece of rubber does not do much to help eliminate drafts around your metal garage door. To get the most out of your insulating efforts, make sure you consider upgrading this door stop along the floor with a taller version made of soft rubber that is better equipped to stop heat and cold from slipping through into the garage. 

Fit the garage door panels with polyurethane foam sheets. 

Polyurethane foam sheets designed specifically for insulating purposes can be picked up at just about any home improvement store. These sheets work well on the backside of a garage door because they do not leave a messy look like rolled fiberglass insulation. Plus, the polyurethane foam sheets can be cut to size to perfectly fit on the backside of each panel of the garage door, which is important so the garage door can still move as it needs to when opened and closed. You can simply use double-sided tape or some other adhesive to hold the lightweight panels in place. 

Seal gaps around windows appropriately with silicone caulking. 

If your metal garage door has windows, chances are, there is little insulation around this area to ward off drafts and hot air. You can better insulate the gaps around these windows with a basic silicone caulking and a caulking gun and it really is not that big of a deal. Simply apply a bead of caulking on the backside of the window where the glass or plexiglass meets the existing rubber seal and you're good to go.
