Insulation will help you lessen the thermal transfer between the interior and exterior areas of your home. You will make your house more comfortable, lessen your electric bills, and you’ll help the environment as well when you add insulation. Many homes have insulation already in their roof and walls. An un-insulated garage door is the perfect chance to enhance the insulation levels in your home. Adding insulation to your metal garage door will be so easy. It will make your family more comfortable.
A garage door is usually a big un-insulated space that causes energy losses especially if it’s connected to your home. If your garage isn’t insulated, and if you aren’t concerned in soundproofing or comfort, then there’s no need for insulation.
However, if your garage is below or adjacent to your living room, or if you use it regularly, then you need a garage door that gives soundproofing, thermal comfort, and energy savings. Below are some tips to help you to insulate a metal garage door.
- Measure your garage door panels. Purchase polyurethane foam sheets from local hardware shops. Cut the cover with a knife using panel measurements. Along the garage panels, insert the foam through a putty knife, and then cover it with an aluminum foil tape.
- Purchase polystyrene foam to utilize as alternative insulator. Cut the stiff polystyrene out in the needed measurement, and then stick it to the garage panels. Fasten the panel brackets to the foam to protect insulation.
- Use an alternative way of utilizing a double layer of weather strip to seal the door easily against cold or warm drafts. To expose the adhesive side, take out the backing material from the weather strip. The adhesive side must be facing downwards to the garage door panels. Put hand pressure to stick it, you can hammer nails to pin it down as well.
You can use a neoprene or vinyl seal to line both sides of your door. You can prefer a more durable screw-on, or a more economical stick-on seal.
For the base of your door, select a flexible and large neoprene seal. Vinyl is too rigid for this application type, although neoprene’s softness is sufficient to endure frequent use. The easiest to install are stick-on versions, while the screw-on door bottom is the most durable.
- There are ready made garage insulation kits in your local hardware shops. Just follow the manufacturer’s instructions carefully for proper installation.
- Try the insulation as you install it. Close your garage door and observe if there are any outside draft coming in.
Before you insulate your garage door, you must understand the insulation level that you need, which is based in your local climate. Insulation levels are identified using R-value, which portray the thermal resistance of an assembly or a product. A garage door must have a 5 R-value in moderate climates and a 10 R-value in much colder locations.
You can buy sturdy weather strip that can last for years. Keep in mind not to stretch the weather strip because it will lessen the effectiveness.
