Browse Forums Windows & Doors 1 Oct 01, 2023 7:58 am Hi Need some advice on best way to flash the thresholds for stacker doors. Currently there are no weep holes and the DPC is running across top of threshold, I think this is problematic for the door installation because the inside slab edge is roughly 10mm lower than the external brick. And the flashing will create a moisture pond. Should we grout the cavity ?

Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ This looks like the slab has been recessed to make the finished floor level (i.e. including floor coverings) to be level with the sill. This will be to fit a specific door sill height, and may include a drain below the sill. The sill must drain beyond the bricks. Don't grout the cavity.

Make sure you dont put holes in the tray. Thanks for the feedback, the door installer will be putting holes into it to install the frame and subsill. Here is a sample with the frame. It’s about 160 wide. The internal floor will be about 20mm on top of the concrete. So the frame can sit flush…The concrete rebate is 50mm. The frame total with subsill is 60mm. The concrete rebate is about 90mm wide. the frame is about 160mm wide. They can’t drill into the brick, so they are limited to the concrete rebate.. Iv been told you need about 50mm concrete cover for the brick.. so basically the frame will be bolted from back end. The front end will be floating. If we run the DPC under the frame, and they pack on top of it I think it will trap water. Maybe it needs ro be packed under the DPC. Iv been told that if you can’t install DPC properly to grout the cavity and water proof it.. others have said not too… as it will remove the air cavity between the concrete and bricks…. so confusing.. I just need it to be done correctly so that no water will back track. I think the external brick needs ro come down.. the brick layer mentioned to take out the brick install the door then they will brick back under it.. however the door installer will need the bricks in place to pack the door frame….

Iv been told it’s not as good as the black grey one. wich single tray and sits further in the from the outside.. Re: Stacker door thresholds 7Oct 11, 2023 6:49 pm Sure looks like the type of track that I fitted to my house. My supplier said that the underside has a tray which drains to the front. They cut vertical slots in it. So as long as the lip sits over the cladding it does not need flashing. In my case, I rebated my joists, then I used a double stud wall, and then screwed some 30 x 90 losp to the bottom plate. Perhaps you could remove the bricks and push them towards the concrete and/or cut them so that lip goes over the face of the brick. What's happening above the door? What do you need them to withstand? If it's normal wear and tear, then either will do, if you want resistance to ingress then laminated would be the favourite, but only… 1 12672 920 was enough to get the furniture in.
