Visofold 1000

The latest upgrade to the Visofold 1000 bi-fold door features a range of enhancements that deliver significantly improved U-values, as well as easier and quicker fabrication and installation.

• While retaining the same overall dimensions and slim sight lines that are such a striking feature of the Visofold 1000 design, new outer frame profiles now incorporate a wider 30mm polyamide thermal break, an increase of more than 60% compared to the 18.6mm break in the original design. When fitted with a double glazed unit with a centre pane of 1.2, this achieves a U-Value of 1.4 and an A energy rating, the slim profiles allowing as much sunlight in to the room as possible to maximise solar gain.* *Note: the U-values are calculated with foam insulation added to the profiles. The system also features a new track insert (DV100), with the polyamide section simply clipping into the track.
• With a choice of two new rebated outer frames (DV17 and DV19N), a new integrated cill, and the existing low threshold option, this latest upgrade also includes the introduction of a DV225 heritage style sash to the range, aligning with Smart’s established range of heritage windows and doors.
• The upgrade also includes optional 70mm UN3570 and 82mm UN3582 hooded trickle vent sections, which provide integrated ventilation.
• As well as improvements to the frames and thermal performance, Visofold 1000’s hardware and accessories range also features a number of significant enhancements, including PAS 24 approval for the door’s standard roller, the addition of new, heavy duty shoot bolt handle and enhancements to the gearboxes.
