Hi, I’m having a few alterations done done to my house and this includes adding 3.6m aluminium bifold doors . I’m trying to get the threshold as flush with internal floor as possible.
To achieve a completely flush threshold, I would need to take the brick level 20mm below the DPC. I’m not happy to do this.
instead, can I not fit a 25mm cill and put the frame on the DPC? This will give me a nice 5mm internal lip on the threshold. I can’t raise the internal floor height.
if it helps, externally I will be having a linear drainage gully along the house. The height of this will be flush with the external side of the threshold.
thanks in advance,
