Insulated garage doors are generally more expensive than non-insulated options. However, both types offer high security and reliability.
Non-insulated garage doors provide a basic level of insulation, while insulated doors offer seals around the door to help prevent wind-driven debris and provide a better seal around the opening. Insulated doors also feature a core of polyurethane foam sandwiched between two panels of aluminium or galvanized steel.
If your garage is attached to your home, has a room above it, or is used as an office, gym, or workshop, an insulated garage door can offer significant benefits over a non-insulated option.
