Garage Door Insulation – How To Guide

Garage conversions into workshops, hobby rooms, children’s playrooms or simply extra living space are on the rise. This increased activity in the garage leaves you asking yourself the question – does it make sense to insulate a garage door?

If you are planning on spending more time in your garage, then you should ensure the room is well insulated, not draughty and comfortable to be in.


Should you Insulate a Garage Door?

Installing garage door insulation will not only help you to keep warm when you use your garage, it will also increase savings on heating bills for your entire property.

  • Uninsulated garage doors increase your heating bills as they allow space for cold draughts to enter your home, which constantly draw heat from your property.

Types of Garage Insulation

There are a few different types of garage door insulation, the most common types being:

  • Polystyrene foam
  • Panel insulation
  • Reflective foil insulation

While it is probably possible to insulate a garage door using fibrous insulation, it is not very practical and very seldom done.

Lightweight Garage Door Insulation

Choosing insulation that is lightweight and thin is extremely important when you decide to install insulation on a garage door. If the insulation is too bulky or heavy it will cause problems for the lifting mechanisms and the door runners.

Lightweight kits should weigh less than 200g per m2 to ensure they don’t damage the running gear of the door.

Best Material to Insulate a Garage Door

Reflective foil insulation is probably one of the best materials to insulate a garage door. Along with being lightweight, they are usually:

  • Quick and easy to install
  • Effective at reducing draughts
  • Easy to clean
  • Sound deadening

Do not be fooled by Mylar products. Metallic plastic may look ‘shiny’ and be good at reflecting light but they do not reflect heat in the same way as aluminium. That is why they are so cheap, the ‘foil’ surfaces break down, they delaminate and tend to have poor fire ratings.
