One of the newest products in our diverse range of aluminium doors are Alutech bifolding doors. Slimmer than most other folding sliding doors on the market and fully compliant with the June 2022 revised Part L of the Building Regulations, Alutech bifolding doors are perfect for residential property renovations, new extensions and even as a reliable solution in cafes, bars, and restaurants. Here is everything you need to know about this latest-generation folding sliding door.
Alutech bifolding doors – one of the slimmest on the market
One of the best features in our Alutech bifolding doors and an important requirement with many buyers are the mullion dimensions on the closed doors. And here, this product is one of the slimmest on the market with a sightline of just 100mm.
It’s the slimmest bifold in our range and provides larger glass panels, better views and reduced visible aluminium. Another benefit of more glass is even better energy efficiency with a B Energy Rating and meeting the requirements of June 2022 Part L.
Alutech bifolding doors are slimmer than other mid-range brands such as Smart Systems Visofold 100, Aluk doors, the Origin brand, and many others.
Here is how the Alutech BF73 bifold compares with our other brands in terms of Mullion sightlines:
- Alutech BF73 100mm
- Senior Architectural Ali Fold 123mm
- Reynaers CF68 131mm
Another benefit of choosing this brand for bifolding doors is its styling as an excellent steel-look bifold. Most bifolding doors in the heritage or steel style are otherwise standard bifold but with applied powder-coated slim bars on the glass. The slimmer the bifold at the mullion, the better it looks.
Larger door panel sizes with Alutech BF73 bifolds
Helping your residential or commercial clients create bigger bifolds are the impressive panel sizes. With a maximum width of 1200mm wide and a maximum height of 3000mm high, Alutech bifolding doors meet the requirements of new extensions for bigger bifold doors and without the need for intermediate steel and fixed window above.
Therefore, where the project calls for bigger-than-average bifolds, Alutech provides an excellent solution. And again, the impressive size capability you will find with this product exceeds that of other leading brands at a more affordable price.
Another advantage of the larger panel capability is you can use Alutech bifolds as excellent single or double doors, going wider and taller than other conventional aluminium residential doors. It’s another excellent selling point to these doors, where projects not only need hinged side or rear doors to match the bifolds but where you would prefer a full door set without side or top panels. And the slim mullion sightlines make these slimmer than regular residential doors at the meeting mullion too.
An extensive choice of profile types and styles
Cleverly designed to meet the requirements of both modern and more traditional property types, the Alutech bifold systems comprises a significant choice of different profiles. Not only do these provide the right styling, but also ensure the system suits different applications, for example, internal bifold doors or heavier-duty applications. The system even allows the fabrication of fixed panels, again providing matching sightlines where the project requires picture windows beside the bifold.
In addition to the standard fully weathered track, you get a choice of a flush threshold for internal use and a lower-profile version, again where full weathering is not required. The ramp-type threshold can be considered for commercial door sets where the threshold needs to meet the requirements of BS8300 and Part M Building Regulations for accessibility.
For the sash profile, there is a 48mm slim sash or a 61.6mm standard model. These both work with the 55mm transom section should the design call for a middle rail. Five different cill section range from 90mm up to 230mm, meeting the needs of most retrofit or new build installations.
With many new build installations needing trickle ventilators, the system comprises a dedicated profile 38mm high, allowing most trickle vent models to sit neatly at the top of the frame. And there is a 20mm head adaptor acting as a frame extension.
The same choice extends to the door hardware, with numerous profiles designed to customise Alutech bifolding doors. Hoppe and Vivoshort handles operate master and intermediate panels. These come in White, Black, Grey RAL 7016, Chrome, and Brushed Satin finishes.
One of the most fitter-friendly bifolding doors
The adjustable frame jamb you get with Alutech bifolding doors makes the final adjustment of the door set as well as the overall installation a breeze.
The optional adjustable jamb feature provides +/- 4mm of adjustment on either side of the bifold. Even better this adjustment is available for a competent person well-after the install, should the doors require routine adjustment in the future. All that is needed to make the most of this useful feature is an Allen key.
Where you can use Alutech bifolding doors
This versatile and well-designed folding sliding system is perfect for the replacement of old doors and of course in a newly built opening. The systems features a 73mm deep outer frame, meaning door replacements have minimal disruption to internal plaster lines. It’s just as convenient to fit Alutech bifolding doors in a new opening too.
Available from two up to seven panels, a fixed corner design and matching hinged doors as well as a choice of frame and sash profile styles. Quality hardware such as a six-point locking system with star-rated cylinder, excellent door sealing, high security and professionally applied powder coated colours all come as standard.
