Smart Bi folding System
Aluminium bifolding doors offer a sleek, modern solution for seamlessly connecting indoor and outdoor spaces. Known for their strength and durability, aluminium frames allow for slim profiles and larger glass panels, maximizing natural light and creating a spacious, open feel. These doors are low-maintenance, resistant to rust and warping, and provide excellent thermal efficiency with proper glazing. Their elegant, minimalist design adds a contemporary touch to any home, enhancing both aesthetics and functionality.
Description
Smart’s Visofold 1000 is the UK’s most popular aluminium bi-fold door, delivering a range of benefits for the fabricator, installer and end user.
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.
Improved thermal performance
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.
More Profile Options
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.
Accessories and Hardware
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.
