If you were to have this same insulation professionally supplied and installed, typical pricing is:

Single Garage Door: $750-$900 GST

Double Garage Door: $1,100-$1,200 GST

Because Premium Garage Doors purchases this product in large volumes for our own installations, we're able to offer genuine DIY pricing and pass those savings directly on to our customers. Easy DIY Installation

Simply measure the thickness of your garage door panel.

The insulation slides neatly into the steel frame channels or lips of sectional door panels.

No glue.

No tape.

No clips.

No mess.

The finished result closely resembles a factory-insulated garage door.
