When homeowners ask about „schuco bifold doors”, ASS 70.HI is almost always the system in question. It is Schüco's principal folding-sliding door and by some distance the most commonly specified option among schuco aluminium bifold doors in UK single-storey extensions.
Configurations and traffic door
The system supports up to seven sashes in a single run, with the option of designating one of them as a traffic door — a full-height single leaf used for day-to-day access without having to fold back the entire elevation. It is a small detail that changes the way the doors are actually used.
The HI in the name
The „HI” designation refers to the improved thermal insulation profile. Uw values from 1.2 W/m²K are a strong result for a folding system carrying that many moving joints and gaskets.
Choosing among schuco bifold doors suppliers
Standards of finish among schuco bifold doors suppliers vary more than they should. A folding system is far less tolerant of small installation errors than a fixed pane, so it is worth insisting on a site visit to a completed job of comparable size before signing.
For readers researching options locally, the bifold showroom in Hertfordshire and 5EC's bifold range are both worth reviewing — both are handled by 5EC, a Stevenage-based authorised supplier working across Hertfordshire.
Detailed technical documentation is available on the ASS 70.HI datasheet.
