There are a few ways to retro-insulate an existing door. You can use a special insulating kit purchased from the manufacturer for your specific door (click here to purchase one for your door) or you can go totally DIY and use either polystyrene panels or expanding spray foam from your local home improvement store. The biggest issue with either the panels or the foam is the wear every time a roller-panel door is opened or closed. The panels or foam tend to degrade quickly, usually over the course of just one winter. One exception to this is the swing-out or swing-up door: added insulation will stay in better shape on these types of doors since there aren’t as many moving parts to provide friction.
Another option is installing an already-insulated door. There are two main types of manufacturer insulated garage doors: sandwich construction and vinyl-back construction.
Sandwich Construction is probably the most effective insulation option, consisting of two metal skins bonded together with one of two types of insulation hidden between.
- Polystyrene sheets cut to fit and glued between the panels are good for occasional heat retention and high durability (the doors resist denting and other lifetime damage).
- Polyurethane expanding insulation injected between the layers of an assembled door produces even insulation across the entire inner surface of the door. This type of insulated door is best if you want to maintain a fully–heated garage space.
Vinyl-Back Construction uses expanded foam cores on the interior of the garage door, strengthening the door against dents and adding temperature control without the expense of a second interior steel skin. The advantage is mostly in price since the door will not be as durable or effective as the sandwich style.
