Thresholds For The Aluminium *SolaTHERM* Door Range
The SolaTHERM range of aluminium bifold doors are a designed with ultra slim sightlines. To achieve this the bottom rollers are sunk into the outer frame, which consequently does not facilitate the option of a low threshold. Therefore all doors are supplied with a rebated threshold with either a standard external cill or flush cill.
The two CAD images below show dimensions for the rebated with external cill and flush cill option. Click on the relevant links for your chosen threshold to show open out, in and buried enlarged printable images.
Standard rebated thresholds are fully weather rated.
