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

    Very Comfortable Ergonomic Chair - Great for Long Work Days!
    Color: Black, Color: Black
    I’ve been using this ergonomic office chair for a couple of weeks now and I’m genuinely impressed. For the price, it offers excellent comfort and support. What I like: • Very comfortable padded seat and backrest — I can sit for 8+ hours without back pain. • Good lumbar support and adjustable height/armrests. • Holds up to 330 lbs easily (I’m 240 lbs and it feels very stable). • Smooth rolling wheels and sturdy base. • Easy to assemble (took about 20 minutes). The mesh back breathes well and doesn’t get hot. It looks professional in my home office too. Overall, this is a solid ergonomic chair. If you spend a lot of time at a desk, I highly recommend it. Would I buy it again? Yes, definitely.

    Great if you're average height.
    Color: Black
    Comfortable for the price. The seat could be a bit better, but for a budget friendly ergonomic chair, it's well made and has helped a lot with my back pain caused by my previous desk chair. Assembly wasn't terribly difficult, though I did have one screw with damaged threads. Luckily they ship spare screws in the kit, so that was a non-issue. Rollers work great on my small rug and hard flooring and don't tend to tangle cords or cables too much. Size wise, works great for my frame (5 ft 6 in) but for someone more than a few inches taller than myself, you should probably look at another chair.

    Great chair
    Color: Black
    I am very happy with my purchase. Easy to assemble but be aware your drill bits included with your set won't fit their screws. However, you can get a fair bit done with the drill and then use tool included to adjust. Super comfortable and exactly the right height for my desk. Highly recommend for quality exceeding price point.

    Review from an "actual" tall person who doesn't weigh 400 pounds.
    Color: Black
    I recommend this chair. Firstly, I looked at least dozens of chairs and nearly every review in trying to select a chair. I didn't want to spend $200. It's confusing because everyone's idea of perfect is of course subjective. One thing, What is tall? I'm 6'6" I think that's pretty tall. Others feel that 6'0" is tall. LOL In the listing, it shows this chair is good for a 6'5" person which I think is pretty accurate. I weigh about 210 pounds and the padding is just fine. One thing I would push manufacturers to do would be to give accurate measurements. Seat height low and high. Back support height. Head rest added to back height etc.! Maybe actual human measurements that the chair is geared toward. Nice to know that 400 lbs is cool but that doesn't tell me much. My primary goal was to find a chair I could sleep in because I recently had a back injury and sleeping on my bed, while fine, resulted in intense pain trying to get up in the morning. We'll see what happens but the headrest reaches my head which was goal one. The lumbar fits so I don't need to use cushions and pads etc. I found the upper position of the support to be right for me and it's super comfortable. Plus number two. The raised height of the chair fits my long legs (inseam 36") Plus three. I wanted adjustable arm rests but this one doesn't have that. No biggie, for me the height of the arm rests is pretty much just right. It might be a little high for some. The back leaning adjustment doesn't lock except for upright. Locking upright is good, and leaning back - for me - doesn't really need to lock. Being an actual tall person made me really skeptical. I'm relieved that I won't have to take it apart to return it. The assembly was straight forward and pretty easy though I'd suggest not really tightening the arms snugly before getting the back squared away - the alignment is easier if you do that. I got the chair for $109 with 21% off. It's slightly wobbly yet feels pretty well made. It rolls well enough. I'm quite satisfied with the purchase and I'll come back if there are updates. Edit one. I've had it a week now and found I couldn't sleep in it. I think it would be better if the back could recline separately from the seat. There might also be figuring out a way to support my legs due to the back and seat reclining together rather than separately. Two. I kind of wish more now that the arms were adjustable for height and tilt if that makes sense. I have a bar stool next to me on the right in front of my desk that is the right height to relax my right arm while reaching my mouse on the desk so that's my work around there. Three. The casters are kind of basic and don't roll as easily on the floor matt as my former second hand chair - they would probably be fine on a hard surface. I'll probably switch them out. Four: The lumbar support, while mostly in the right place is unpadded and creates kind of a hard spot there. I've re-introduced my lumbar support pillows for comfort there. All in all, I'm still happy with the $100 purchase. In my experience, being pretty tall always comes with compromise and these notes are not deal breakers for me. Yea, It can always be more perfect but unless you're in a showroom test driving and willing to spend $300? Right. UPDATE: I'm really not satisfied with this chair and in fact, I wish I hadn't bought it. Firstly, the pneumatic post that the chair part connects with is wobbly depending on which way it is facing according to which way the legs are aligned. It's like a poor fit and I'm pretty mechanically inclined. Second and also important. The lock to keep it upright and inclined only worked for a few weeks. For a while, you had to mess with it to engage the upright position. It no longer works. Worse than that, the lumbar support pad disconnected with the chair and is now floating and after only a month or so, the remaining supports for the Lumbar rest have dug into the fabric on the back of the chair creating holes in the back's fabric. I've tried but there is no way to reconnect that bit without removing the back's fabric as far as I can see. I'm taking this down to one star for sure. Poor design? Poor manufacturing? Yea. I wouldn't suggest this chair to anyone. If the company comes up with a solution, I'll continue my review. As for now. Not a recommendation. Update: Not impressed and kind of crappy. Mentioned is that the so called lumbar thingy disconnected and is unusable. I've got my own pad which seems to help. Also, it's wiggly where the chair connects to the base. Months later, I might toss it and go back to the chair I bought locally and second hand. Don't buy this chair!

    Great Instructions, Straightforward Assembly
    Color: Black
    I just received this chair today, so my product review is mostly on the packaging, instructions, and assembly. The product was well-packaged, and it was obvious when I unboxed it that a lot of care and thought went into packing it in the most efficient way that would also protect the parts. I was positively impressed with the packaging. I was also incredibly impressed with the instructions and assembly process. I am used to cheaper products where the parts only half fit or important components are missing, or where the instructions were confusing and unclear. This chair's instruction manual was very clear and concise. The diagrams were easy to understand and neat. The screws came labeled and separated and also included the scew types and sizes/lengths, which is handy in case you need to pick up extras at a store somewhere. But they also included one extra of each type of screw, washer, and cover, which I appreciated during assembly. (I didn't find myself worrying what would happen if I dropped a screw, which is something I would normally be distsracted by while working.) The only things I would take points off for were these: 1. The instructions said the chair came with gloves for assembly, but no gloves were included. That was fine with me, but why mention them if you won't include them? The instructions even later say not to use the chair if not all components were present...but all the important ones were, so I assembled it without gloves (as I probably would have done anyway, since it was for me and not another person). 2. It matters which side of the seat is the front, but the sticker was confusing. The instructions show a sticker placed on the side that is the front, and that is where my sticker was placed. However, the sticker says "FRONT" and has an arrow pointing somewhere. In the instructions this arrow pointed to the front. On my seat, however, the arrow pointed to the back. So am I supposed to believe the sticker placement (it was diagonal, so it looked haphazardly slapped on) or the arrow? On that particular step the piece you are screwing into the seat can fit both ways, but thankfully there is a later step where it becomes obvious which side is the front vs. the back. (The arm rests can only be attached to the back.) So I wish that had been clearer up front, but otherwise it was okay. Recommendations for assembly: - To attach the wheels, apply firm, direct, straight-down pressure. I tried screwing them on at first but you just push. Make sure they go in the whole way like the picture shows. - When they say to tighten the screws to only 60%, it's a helpful tip, because you can't fit the armrests on both the seat and chairback at the same time with the screws completely tightened. Just tighten them enough to fit the pieces on, then later you can tighten up the screws. So far I find the chair to be very comfortable and I'm exceedingly happy with it. The lumbar support seems like it could potentially be a little chafy or scratchy, but I'll give the chair a chance before deciding if it's problematic or not. Like I said, I only got the chair today, so I can't speak much to its long-term comfort, durability, or longevity. But I was so impressed with how easy and straightforward they made the assembly that I had to write a review to show my appreciation.
