Complete Guide on choosing the Correct Garage Door Threshold




Weather Stop Threshold Guide


Choosing the correct seal for you garage door is very simple and can be done in a few easy steps:





What are the Garage Door Seals and how do they work.

All our seals prevent leaves, dust, debris and vermin from entering the garage as well as protect against drafts, wind-blown rainwater, standing water, cold air and snow.

Our flood barrier is also available if you have a large amount of standing water.

The seals are completely watertight when fitted with our adhesive and serve as a superior alternative to rubber as our products are 100% recyclable making them environmentally friendly, odourless and will not rot, decay or lose their colour with prolonged exposure to water or sunlight.

The seals prevent vermin such as mice or rats, spiders, or other insects from entering through the gap under your garage door.


How It Is Fitted

 The threshold fits behind the garage door to ensure that a tight seal is formed when the garage door is in the closed position.

Our garage door thresholds were designed with you in mind. Anyone with basic DIY skills will be able to fit our range of seals. The seals come in a variety of lengths and heights and are made with either aluminium or flexible thermoplastic material.


Below are The component keys for the thermoplastic and aluminium thresholds:

Choosing the correct size

To find the correct size of threshold for your garage, all you need to do is measure the gap between the bottom of the garage door and the floor in a number of different places then note the largest measurement. As your floor is unlikely to be completely level you should measure the gap in at least three or four places to ensure you determine the largest gap.

Measure the gap

 
If the largest gap between your garage door and floor is 18mm - The 20mm Garage Door Seal will be just right for you (please note that if the highest gap is the same height as one of our seals you will need to go one size up to ensure an effective seal). If you want a larger seal you can go as high as you want, but not lower.


Product range:

15mm Threshold Seal
20mm Threshold Seal
25mm Threshold Seal
25mm Ramp Threshold Seal
30mm Threshold Seal
40mm Flood Barrier
15mm Commercial Threshold Seal
25mm commercial threshold



Uneven Floors

The Garadry Ramp Design seal was made specifically with this in mind. If the gap between your garage door and uneven floor is less than 25mm as its largest, the 25mm Ramp Design Garage Door Threshold Seal will do the job (also works for sloping floors).



Measure the gap

When faced with a particularly uneven floor with a gradient larger than 5mm between its lowest and highest points it is recommended that you use the 25mm Ramp Design Garage Door Threshold seal.

 
If this isn't high enough, the 40mm Flood Barrier/ Flood Diverter will also work on uneven or sloping surfaces. if you have an uneven floor but would like an aluminium threshold, an effective seal can be achieved with adequate preparation of the floor.

Choosing the correct length

To find the perfect length of garage door seal for your garage door you will need to measure the width of the opening.

Measure the Width

If the width of your garage door is 2.9m you would select the 3.12m long Garage Door Threshold Seal.


Creates a Water Tight Seal

Generally our floor threshold seals come with a bit more length than you'll need for your garage door as the ends should be cut into an 'L' shape to allow them to seal snugly around the frame, ensuring no water can enter.



*Seals can easily be cut with a sharp knife, pair of scissors or a hacksaw.

Alternate Uses

While our seal strips were specifically made for sealing the gap under your garage door, some of our customers have found very innovative ways to make use of them outside of sealing their garage. These include:

Using the seal to contain spills - The seals are chemical and oil resistant and could be used to manage spilling to an extent.

Using the seal as a flood diverter - Placing the seals across your gate, driveway or premises to divert water.
