The photos above show the same door from inside and outside. You probably noticed the difference between the photos at the top and bottom.
Unfortunately it´s still a common practice here in Ireland, that doors will be installed without any appropriate support under their threshold. Some blocks to the left and right to adjust the
required height and off we go!
Load bearing, Thermal Bridging, Insulation? The most installers would probably answer in a charming way: "I´m not getting paid for!"
Thankfully the most self-builders, architects, engineers and passive house consultants have noticed the importance of the door threshold detail already. But some of them do still chase the right
strategy and product...
When I started my business here in Ireland, I was always recommending adjustable brackets as I have used them in Germany approximately 15 years ago. These metal brackets were ideal for the load
bearing support of the doors but unfortunately the problem with thermal bridging had to be solved separately.
