Colours & Finishes

Door colour: Anthracite Grey

Standard colours

Inside and outside finishes can be discussed separately where the chosen range allows.

Aluminium Bi-Fold Doors in Anthracite Grey

Traffic-door and hardware finish: Black

Bi-fold hardware is planned around daily access: traffic-door handle, panel catches, locking, stack direction, and whether the threshold is standard or lower access.

Made to measure. We show the relevant colour and hardware options during your survey before anything is finalised.

Specification Choices

Set the bi-fold around panel count, threshold detail, and daily use

Start with the priced panel count, then refine stack direction, threshold, colour, glass, and hardware once the opening has been measured.

Made to measure

Panel count and guide price sit together

These are the four panel-count options currently priced from the sheet. The final layout still depends on the measured opening, stack direction, threshold, and site conditions.

2-panel bi-fold

2-panel bi-fold

£1,799From

from price for a 2-panel fitted set

A compact bi-fold route for narrower garden openings where a simple pair would not give the same folded access.

  • Narrower rear openings
  • Same colour inside and outside
  • Dual colour priced separately
3-panel bi-fold

3-panel bi-fold

£2,699From

from price for a 3-panel fitted set

A common mid-size layout where daily access, traffic-door planning, and stack direction need to be agreed early.

  • Medium garden openings
  • Traffic-door planning matters
  • Threshold confirmed at survey
4-panel bi-fold

4-panel bi-fold

£3,599From

from price for a 4-panel fitted set

A wider family-opening option where the folded stack, traffic route, and patio line need setting out together.

  • Wider rear elevations
  • One-way or split-stack layouts
  • Hardware route confirmed in quote
5-panel bi-fold

5-panel bi-fold

£4,499From

from price for a 5-panel fitted set

The largest priced layout in the current sheet, suited to larger openings where maximum clear access is the priority.

  • Largest current guide option
  • Stack space checked first
  • Panel weight confirmed from sizes

Guide prices are starting points, not final quotes. Dual colour, upgraded hardware, specialist glazing, threshold changes, making good, and unusual site conditions are quoted separately. Aluminium supplier costs can move, so written aluminium quotes are normally held for around 7 days.

Technical Details

Specification and Options

Optional Upgrade

Integral blinds for a cleaner bi-fold opening

Integral blinds suit bi-fold projects where the finished opening needs to stay sleek and uncluttered. The blind sits inside the glazed unit, so there are no loose cords, no exposed slats to clean, and no surface-mounted blinds fighting with the folded panel stack.

White internal bi-fold doors with integral blinds sealed inside the glass units

Between-glass shading

A discreet blind sealed inside the glass unit, planned panel by panel during survey.

Useful on bi-folds when

  • The rear room is overlooked but still needs a wide garden opening
  • Curtains or surface-mounted blinds would clutter the folded stack
  • You want glare control without losing the minimalist aluminium look

Blind types we can discuss

Magnetic integral blinds

A slim magnetic slider raises, lowers, and tilts the blind inside the sealed glass unit.

Electric integral blinds

Remote operation suits larger panes, harder-to-reach glass, and cleaner contemporary rooms.

What we check

  • Panel size, glass weight, and unit depth
  • Traffic-door position, handles, and threshold detail
  • Whether the blind layout should cover every pane or only selected panels

Magnetic and electric options can be discussed. Suitability depends on pane size, panel layout, glass specification, and final survey.

Aluminium bi-fold doors are usually chosen when a Romford or Essex home needs the rear opening to fold back as widely as possible. They suit kitchen extensions, garden rooms, and open-plan rear elevations where panel count, stack direction, traffic-door position, threshold detail, and patio levels all affect daily use. We show approved 2, 3, 4, and 5-panel guide prices as a starting point, then confirm the measured opening, colour, glazing, threshold, hardware, access, and making good before issuing the fixed quote.

Key Specifications

Large panel sizes are supported without the bulky look of older folding-door systems

Double and triple-glazed configurations are available depending on thermal and acoustic targets

Class 4 air permeability, E750 water tightness, and C3 wind resistance on the tested platform

Anti-lift hinge design and PAS 24 option for higher-security specifications

Single and dual-colour powder coating across the RAL range

Low-threshold and standard threshold options to balance access and weathering
