Our Smart Visofold 1000 Slim Bi folding doors are designed to complement any style while remaining budget-friendly. Thanks to the exceptional strength of aluminium, we achieve a sleek, slim profile without compromising durability, aesthetics, or functionality.
Manufactured using thermally broken profiles, our bi-fold doors maximize glass width with minimal panels, allowing for uninterrupted views and enhanced natural light. The Visofold 1000 slim frames have been reduced by 10mm to 122mm, to make the glazing area even larger. Since glass makes up approximately 80% of the door’s surface area, its specification plays a crucial role in thermal performance. To ensure superior insulation, our doors feature multiple rigid rubber seals and draught excluders—allowing nothing but sunlight to pass through.
Our advanced bi-folding system incorporates the latest polyamide thermal barrier technology, creating a protective layer between the cold outdoors and the warmth inside. This innovation helps retain heat, minimize condensation, and insulate against external noise and weather conditions.
Our Slim Bi folding doors come as standard with colour matched Magnetic catches where applicable. Black D pull handles, for use on the intermediate doors, matching the std Black hinges and gaskets around the opening sashes. Locking intermediate handles and matching secondary door handles will be fitted as required, symbolised by “S” (secondary door).
Our Slim Bi folding doors also offer an integrated cill threshold, giving the option of a lower threshold whilst retaining weather protection, only available on outward opening doors. Our additional sub cills are available in various sizes to allow for your requirements up to 225mm.
As trickle ventilation has been a requirement since 2022, Our Bi folding doors offer these to be fitted within a 42mm frame add-on, situated on top of the door frame with colour matched compliant trickle vents.
