Crofter Posted July 31, 2016 Share Posted July 31, 2016 What's best practice when setting the height of an external door in a new build, where the finished floor level may still have some uncertainties? I have my joists and 22mm chipboard down, but the final flooring may be 10mm or up to 16mm, depending on what I end up buying... then there is the idea of 'future-proofing' in case I was ever to replace the flooring material. What would be a good height to set the threshold above the chipboard? Thanks Link to comment Share on other sites More sharing options...
Tennentslager Posted July 31, 2016 Share Posted July 31, 2016 I'd say as low as possible while retaining weather proofing. What type of door? Mine are upvc which come in a frame. Don't like the trip hazard as it's so high even with 25mm flooring inside which reduces the height...it's still around 40mm Link to comment Share on other sites More sharing options...
Trw144 Posted July 31, 2016 Share Posted July 31, 2016 Why don't you plan for your worst case (highest build up) and you could potentially make this up if you wanted a flush threshold? Link to comment Share on other sites More sharing options...
Crofter Posted July 31, 2016 Author Share Posted July 31, 2016 It's alu-clad timber with an aluminium threshold built in. Never going to be level but obviously I don't want it any higher than it has to be. 'Worst case' height is definitely what I was thinking of planning for, just wondering what this actually means? The planned flooring is bamboo, which could be as little as 10mm, but if say I got a great deal on some solid timber etc, what is a reasonable maximum thickness to plan for?
