Hi all,
Would greatly appreciate some advice on the following please.. :
When fitting a new door sill (upvc / 150mm) and pre-hung doorset (upvc frame with a low-level aluminium threshold), which of the following would be ‘standard/best practice’.. :
- Bed the upvc sill on the sub-sill (brick/mortar) first and then place/position the doorset on top;
or
- Fix the upvc sill to the base of the threshold/frame first and then place/position the whole/complete set on the brick/mortar sub-sill..?
Many thanks in advance..!
