One small step for a bifold . If your wondering how much floor height you'll have on the inside of your bifold installation, when specifying a low threshold its important to know the relevant heights;
Neofoldz cill is 25 mm high
Aluminium low threshold 20mm
Total height 45 mm
If you'd like an aluminium ramp on your bifold this can be also be specified
when the ramp is fitted it leave 25 mm of cill on the inside ie your floor height
With a standard Neofoldz outer frame you have a total of 60 mm height
