All of the doors that we at Kloeber supply, from front/entrance to bifold, sliding and French, will have a threshold and a cill. When installed, most doors will have a threshold that you have to step over, and there would usually be a small difference between the internal and external floor heights to ensure a fully weather-tight seal. This is not only a little ugly, but it can also be a safety concern when there are little ones around, and in most scenarios, your threshold can actually be installed flush and your doors can still be weather-proof.

To achieve a threshold that is flush with the internal and external spaces on either side of the door you have purchased, the depth of this part of the door can be installed below the floor level. Then, your finished floor inside of your home will be able to line up with the top of the threshold to create a seamless transition from inside to outside, removing the need to step over the threshold when walking outside.

 

 

 

In some homes, this may mean taking out a course of bricks under your existing aperture, which is quite simple for any builder, but it is something that they should be aware of as soon as possible. As with any technical or building query, we’re also always at the end of the phone to advise on any details regarding our doors, so our team will be more than happy to speak with you and your builder too.
