For architects and specifiers
Aluminium bifold door and glazing suppliers for architects
Bifold and sliding doors, windows, curtain walling and fire rated façades, specified across Schüco, Cortizo, Aluprof and Jansen, and made to measure in our own West Drayton factory.
What we offer an architect
- System choice across four manufacturers
- Schüco, Cortizo and Aluprof aluminium and Jansen steel, so the recommendation follows the design and the budget.
- Early technical review
- Drawings, schedules and performance requirements reviewed for interfaces, tolerances and buildability before the design is fixed.
- Made to measure in West Drayton
- Profiles processed, fabricated and checked in our own 60,000+ sq ft facility, with CNC machining in-house.
- Systems you can operate
- A West Drayton showroom with working doors and windows installed, close to our production facility.
- One team from survey to handover
- Estimating, technical, production, installation and close-out under one roof, so what was specified is what gets fitted.
- Residential and commercial
- Private houses and extensions through to curtain walling and fire rated façades.
Questions architects ask us
Which systems can you specify?
Schüco, Cortizo and Aluprof aluminium, and Jansen steel. That covers bifold, sliding and lift-and-slide doors, casement and tilt and turn windows, entrance doors, curtain walling, fire rated doors, screens and façades, and blast resistant glazing. Because we work across all four, we can recommend the system that fits the design and the budget rather than the one we happen to stock.
Which aluminium bifold door systems do you specify?
Mainly the Schüco AS FD 75/90.HI, in AS FD 75 and AS FD 90.HI variants for residential and commercial use, PAS 24 approved, with threshold options down to an ultra-low 4 mm; and Cortizo bifolds, with panels up to 1200 mm wide by 3000 mm high. Both are made to measure in West Drayton, and you can operate them at our showroom before specifying.
What do you need to specify aluminium bifold doors on a project?
Elevations or opening sizes, the number of panels and which way they fold, the traffic door if one leaf is used as an everyday door, the threshold detail (level or upstand), the glass specification for thermal, acoustic and safety performance, the colour, and the security requirement, such as PAS 24. With those we can recommend a system and confirm the panel sizes and sightlines it can achieve.
Do you supply aluminium doors to contractors as well as architects?
Yes. On many projects the doors and windows an architect specifies are bought by the main contractor, so we price the same specification for the contractor at tender: commercial aluminium entrance doors, commercial bifold doors for shopfronts and terraces, sliding doors and windows, supplied and installed. Installers and builders who fit their own can order supply-only aluminium bifold doors made to their sizes.
Can you help at design stage, before a contractor is appointed?
Yes. Send drawings, schedules and the performance you need and we will review the system choice, interfaces, buildability and likely sightlines early, when changing them is cheap. It is far easier to design around a system than to fit one into a design that assumed something else.
Can we see the systems before specifying them?
Our West Drayton showroom has working doors and windows installed, so you and your client can operate them and compare frame depths and sightlines in person, and our production facility is in West Drayton too.
Do you work on private houses as well as commercial buildings?
Yes. We fit bifold and sliding doors, glazed extensions, roof lanterns and entrance doors on private houses as well as commercial buildings, and the same factory and installation teams handle both.
How is performance confirmed?
Thermal, acoustic, security and fire performance depend on the exact configuration, sizes, glass and hardware. We confirm project-specific compliance at technical review against your specification, using the manufacturer’s tested data, rather than quoting a headline figure that may not apply to your openings.
