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.

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.

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.

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.
