Our DIY Garage Door Insulation Kit is the ideal product for insulating any up-and-over garage door. In the colder months it will conserve heat, keeping the garage warm and reducing energy costs. In the warmer months it will keep the garage cool, removing the need for air conditioning and reducing energy costs further. Our DIY Insulation Kit is therefore an essential upgrade for anyone who uses their garage all year round to store items or as a workshop, home office, etc. Once applied, you won’t have to worry about temperature and heat retention in the garage again.

Our insulation kit is both lightweight and effective at preventing heat loss. This is important as additional weight on a garage door can cause strain on the springs and other parts of the mechanism, causing them to fail.

The kit comes in two sizes to suit both single and double width doors:

  • Up to 8'x7' doors. Roll dimensions: 714mm (W) x 7317mm (L)
  • Up to 16'x7' doors. Roll dimensions: 714mm (w) x 14634mm (L)

Key Features

  • Up to 78% reduction in heat loss
  • Compact insulation wadding keeps the weight low but the performance high
  • Foil laminated on both sides, to ensure heat is reflected back into the garage in the winter, and heat is reflected away from the garage in the summer
  • Easy DIY installation, requiring no specialist installer or tools

How much will this garage door insulation kit reduce heat loss?

The U-value for an uninsulated garage door is around 5.88 W/m²K. This is the amount of heat that is lost in watts, for every square metre of door, and for every 1Kk the temperature difference between the inside and the outside.

The U-value with the garage door insulation attached using 2mm thick spacers is 1.28 W/m²K. This represents a 78% reduction in heat loss through the door.

How to insulate a garage door?

Our garage door insulation kit is designed to be easy to install by the average DIY person, without the need to enlist professional help. It is a much cheaper alternative than buying an expensive insulated garage door, which can cost thousands of pounds.

There is an easy-to-follow video which you can find here which will explain all the steps. The installation can be completed in under an hour.

To completely insulate your garage door, it's important to also seal any gaps around the door. For this purpose we sell a range of garage door thresholds, as well as both top and side seals for up-and-over doors.

Why should you consider buying a garage door insulation kit?

Heat will always move from warmer areas to colder areas. As garages often have an integral door leading into the house, this can be problematic as heat will want to escape from the home into the garage and then to the outside. To prevent this from happening it is important to insulate the garage door and prevent any draughts. This will stop the heat transfer and reduce the amount of heating the home will need, keeping energy costs down.

This kit can be applied to any metal up-and-over garage door and will keep it insulated throughout the year. It is also extremely lightweight and will not add extra strain onto the lifting mechanism of the door.

Why is having an insulated garage door important?

Often garages have an integral door leading into the house within the garage, this can be problematic if the garage isn’t properly insulated as it will let heat escape. You want to avoid drafts which will lead the cold air into your house and cause a spike in your energy costs. Our other products such as the threshold seals and top and side seals can be used to reduce drafts that come into the garage and help you seal around your garage door to prevent heat loss.

Additionally, if you use your garage as a DIY workshop or a gym you should insulate your garage door to keep the place warmer when working inside. An insulated door will provide a warmer environment. On the other hand, in warm weather when you’re working in the garage on a DIY project, a garage door without insulation can work like a radiator. This will then make it incredibly difficult to focus and work, which is why you should consider some kind of insulation because as well as keeping your garage warmer in winter it will also help to keep it cooler in summer months.

This kit includes:

  • GaraDry® insulation material
  • Aluminium foil tape (20.0m for single garage doors and 40.0m for double garage doors)
  • Double-sided sticky pads (50 pads for single garage doors and 100 pads for double garage doors)
  • Fitting instructions

    Nice looking. Not very sturdy. Easy to install.

    Update: The shelf slopes at about a 45° angle when you put anything more than about a pound on the outside edge of it. Perfectly fine up against the wall. Just seems like the braces inside aren't long enough to really give the stability needed. Bracket is nice and tight against the wall. Had to add braces underneath to hold a small plant, a photo and a small container. Wa sloping more and more each week The shelves look great and we're pretty easy to install. They have a single bracket that is very easy to mount to the wall and get nice and level.. The downside is that the bracket isn't long enough to go between studs. This seems like a pretty simple oversight. I mean why wouldn't you make it long enough to go stud to stud? Secondly and maybe more fatally the bars that go inside the shelf to support them coming out from the wall are significantly shorter than the depth of the shelf. Unfortunately this means the shelf is only supported the first few inches coming out from the wall so there is the potential for a slight lean forward.. The anchors they send are trash. Cheap soft plastic that just tears and bends with a screwdriver. I would suggest spending $2 and grabbing your own anchors from Ace or home Depot. The shelves are essentially made of a high grade cardboard kind of wood. They are not going to support much weight or last for years and years however there incredibly affordable and look nice and easy to install. Long as your expectations are right you'll be happy.
