This 20mm garage door weather seal kit is your ultimate solution to any garage which has been seeing a lot of water and debris coming in. This garage door floor seal is ideal for garage doors that are not level or for uneven garage floors. The additional height will allow you to create a tight seal along the full width of the door.

Our weather seals are designed to prevent rainfall, leaves, and dust from entering your garage; allowing you to kick back and relax over your weekend rather than spending it cleaning your garage. Make your garage a welcoming place that is clean and dry 24 hours a day.

Our garage door seals will also withstand pressure from most vehicles with no issue allowing you to get in and out without having to worry about coming back to a wet and dirty garage. However if you are dealing with heavier vehicles then you can always look at our aluminium commercial door thresholds who are designed for heavy duty vehicles.

How large is the 20mm Garage Door Weather Seal?

This particular garage door weather seal is 20mm high and 110mm wide, while having a range of different lengths ranging from 2.21 metres all the way up to 15 metres. Regardless of the size of your garage you’ll be able to find one that suits it perfectly and if not then you can always cut it down to size.

What are our garage door seals made of?

Every one of our garage door weather seals is made of PVC material which was carefully curated to not only be environmentally friendly by being fully recyclable but also extremely durable and flexible at the same time. This gives it an edge over similar rubber garage door threshold seals, as our material will not experience wear and tear over time. The last thing you will expect our seals to do is become brittle and split; they will always maintain their original shape.

Will this seal work on my door?

Our range of seals including this 20mm garage door weather seal has been proven to work on all commercial and domestic applications. Whether your door is a roller shutter, a sectional garage door, an up and over door or a side-hinged door our products will always work on any of them. They can also be driven over by a wide range of vehicles; you can find a sheet in our buyer’s guide which will show you the recommended weight limits for our thresholds.

The 20mm high garage door threshold seal has a weight limit of 2722 kg and therefore is suitable for most cars. It is not suitable for forklift trucks, lorries, vans, tractors etc., and should not be used in high traffic areas like parking garages. 

Why should I consider buying a garage door weather seal?

The garage door seal will at the very least provide you with a sense of security and confidence that your garage will always remain dry and clean before you return. This is because of the watertight seal that is created where the floor and the threshold meet using our adhesive, which will keep out any rain and standing water up to 20mm high, alongside the debris wind usually brings with it. Due to it filling up the gap between the door and the floor, it also prevents rodents such as field mice or otherwise from coming into the garage.

We pride ourselves on being environmentally friendly and by buying one of our garage door seals you are taking one step into saving more on your energy over time. This is because the garage door seal will help keep heat in the garage, allowing you to save money on heating. If you have a workshop where you use many tools in the garage, then you should doubly get one as the seal will stop condensation from building and due to this slow down the rusting of your equipment.

This kit includes:

  • A 20mm GaraDry® garage door threshold seal
  • Enough adhesive to install the length of your choice
  • An informational installation guide that comes with a QR code for THIS YouTube video
  • 5-year warranty for this product

      Great, except for the edible one
      Flavor Name: Chicken & Original, Size: X-Small
      My elderly dog and my puppy both love these bones. They are 9lbs and 4.5lbs respectively and this is a good size for them. They also like the next size up and it is manageable for them as well. The only gripe I have is the edible one, it comes apart in larger chunks (that are still very hard) and my dogs swallowed a few before I noticed how large the pieces were. I decided to throw that one away. Its been over a week and no negative side effects so maybe just me being overly cautious. For the price (gold box) just the other two bones were worth it. They last pretty much forever for my dogs, and I would say they are moderate chewers. 4 stars due to the issue with the edible bone.

      My little dog loves these.
      Flavor Name: Bacon & Peanut Butter, Size: X-Small, Flavor Name: Bacon & Peanut Butter, Size: X-Small
      These are the perfect size, texture, and density for my 9 lb chihuahua (rescued, of course! :)) He has a tiny mouth with tiny teeth and very little bite force so he needs a chewybone with a lot of give. I've been impressed with how clean these help keep his teeth (it's the saliva flow during the chewing that breaks down any lingering debris and the action of the nubs against the teeth and gums helps to rub off tartar and plaque, if you care to know the *why* behind it.) These are ideal for dogs like mine, and since small dogs tend to have a lot of dental problems due to overcrowded mouths, I couldn't be more grateful that these exist. These would probably also be good for the many rescued puppy mill dogs, who are often small breeds, who have dental issues due to malnutrition and exacerbated by overbreeding, especially in females whose bodies often rob the jaw bones of calcium for the sake of the fetuses they carry, when the pregnant dogs aren't given an appropriately enriched gestational diet. That leads to the little bleppy tongues sticking out all over that we often see in the canine survivors of back yard breeding operations, puppy mills, and the like. There are a lot of these dogs being rescued and adopted in the U.S. right now and these would likely be ideal for them. (In case any adopters of these little survivors are reading this. :)) These are for gentle chewers only, and there are a lot of dogs who fall into that category. They aren't , however, for dogs with an average bite or higher, which is where some of the complaints you hear about these are coming from. Know your dog's chewing needs and buy the size that fits their mouth, tooth type, and bite strength. My dog barely puts a dent in these after a year or more of chewing (watch for any degradation of the plastic and replace as needed, of course.) For little dogs like mine, these are just fantastic and I hope Nylabone keeps making these type of chew toys to keep our dogs healthy. :)

      My Dog's Favorite Nylabone
      Flavor Name: Bacon & Beef, Size: X-Small
      I've been testing out Nylabones the last couple months for my chihuahua puppy. He's a heavy chewer and too easily tears apart many of them, then others are too hard and I take them away because I fear for his teeth. This set is his favorite so far. He doesn't care about the peanut butter ones, loves the beef one, and is absolutely obsessed with the bacon one. He walks around with it in his mouth whenever he goes anywhere. Unfortunately, my senior chihuahua also loves the bacon one and there is now an ongoing feud over it, so guess I'm buying another pack. I like that these are just a little chewy without being too soft, but I still recommend keeping an eye on them as even my puppy has managed to start to get little pieces off. But it's more as frayed strings than chunk like I've had happen with some of the softer ones.
