I am seeking to replace my external aluminium French doors.
Once the existing door and frame are removed, the opening dimensions will be:
- Height: 2050mm
- Width: 1300mm
I’ve had difficulty finding a company that offers composite French doors suitable for a narrow opening.
After finally locating a supplier who can accommodate the 1300mm width, I am now faced with a height dilemma.
I have two options:
1. Order a door without a sill and use a AM370 aluminium threshold (which would meet my height requirement of 2050mm).
2. Order a door with a sill and AM370 aluminium threshold, but the minimum height for this is 2069mm, which is 19mm taller than my opening.
Questions:
- Is a sill necessary?
- I’ve attached a photo of the current door. There is a row of bricks beneath the frame. Can I cut out the 19mm from the bricks to accommodate a sill, or is there a minimum clearance needed between the door bottom and the ground?
Many thanks
Steve
