Types of Made to Measure Glass Doors
Made to measure glass doors come in several distinct styles, each suited to different property types and opening configurations. British homeowners often choose between sliding, bifold, and specialised systems based on their specific needs and space requirements. The manufacturing process allows for precise measurements and custom specifications, resulting in doors that work perfectly with unusual spaces or specific design requirements.
Bifolding Door Systems
Made to measure bifold doors operate on a tracking system that allows glass panels to fold back against each other. The panels run smoothly along top-hung or bottom-rolling tracks, creating wide openings of up to 95% when fully opened. While standard-sized bifolds might leave gaps or require adaptors, made to measure bifold doors fit precisely within any aperture.
The number of panels in a bifold system depends on the opening width, with configurations ranging from two to eight panels. Odd-numbered arrangements include a traffic door for daily use without opening the entire system. Top-hung systems work particularly well in British weather conditions, as the mechanism stays clear of ground debris and water.
Bottom-rolling systems offer an alternative for properties where the header beam cannot support the door weight. These systems use reinforced roller assemblies in the floor track, with the top guide providing stability. Made to measure bifold doors can accommodate either configuration without compromising the opening size or operation.
Panel sizes for bifolds typically range between 800mm and 1200mm wide. Exact measurements depend on the glass weight, frame material, and overall system design. Made to measure options allow for precise panel sizing to maintain visual symmetry across the whole door set.
Sliding Door Systems
Made to measure sliding doors suit larger openings where maximum glass area takes priority. Unlike standard sliding doors that come in fixed panel sizes, made to measure sliding doors can often feature panels up to as much as three metres wide, with the exact measurements tailored to your opening.
Modern sliding systems use specially designed roller mechanisms that let heavy glass panels move with minimal force. The frame profiles can be set into the floor and ceiling, hiding the tracks from view while maintaining smooth operation. Other types of sliding doors might need wider frames or visible tracks, reducing the glass area.
Single, double, and triple track options provide flexibility in how the panels overlap when open. Double track systems allow two panels to slide independently, while triple tracks accommodate three sliding panels. Made to measure sliding doors can mix fixed and sliding panels in any combination to suit the space.
Slim interlock sections between panels help maintain clear views when the doors are closed. The exact measurement of these sections varies between systems, but made to measure doors allow for the slimmest possible profiles based on the specific requirements of each installation.

Slide and Turn Doors
Slide and turn doors combine the benefits of sliding and pivoting mechanisms. Each panel slides individually along a track, then pivots to stack perpendicular to the opening. This design saves space compared to traditional bifolds while offering similar opening widths.
The panels stack neatly without the need for hinged connections between them, reducing the visible hardware when closed. Unlike conventional sliding or folding systems, slide and turn doors can work around corners and curved openings with specially made tracks.
These systems prove particularly useful in spaces where wall space for stacking panels is limited. The panels can stack either internally or externally, with made to measure specifications ensuring proper clearance in either direction. Glass thickness and panel size calculations take into account the specific requirements of the pivot mechanism.
Custom brake systems control the movement of each panel, preventing unwanted sliding or turning. The made to measure nature of these doors means the braking force can be adjusted to suit the panel weight and size, ensuring reliable operation in all conditions.
When Standard Door Sizes Can Fall Short
The limitations of standard-sized glass doors become apparent when dealing with older properties or unusual spaces. Made to measure glass doors resolve many common fitting issues that arise with pre-sized options, particularly in buildings with non-standard dimensions or structural quirks.
Dealing with Period Properties
Period homes present unique challenges when installing glass doors. Victorian and Edwardian properties often feature unusual ceiling heights and non-square openings, making standard-sized doors impractical. Original features like decorative plasterwork or dado rails can interfere with standard frame sizes, while common period property issues like bulging walls or uneven reveals make precise measurements essential.
Georgian properties frequently have tall ceiling heights that standard door sizes cannot fully utilise. In these cases, made to measure glass doors allow homeowners to maintain the original character of their property while adding modern glazing. The ability to specify exact frame heights means the doors can stretch from floor to ceiling, preserving the grand proportions typical of Georgian architecture.

Uneven Walls and Floor Levels
Managing Structural Movement
Buildings naturally shift and settle over time, creating uneven surfaces that standard doors struggle to accommodate. Walls that aren’t plumb or floors that slope require precise measurements at multiple points to ensure proper door operation. Made to measure glass doors can be manufactured with allowances for these variations, preventing issues with opening and closing.
Floor level differences between indoor and outdoor spaces pose another common problem. Standard door sizes might leave gaps or require unsightly adjustments to work around these differences. With glass doors made to measure, the frame heights can be adjusted to account for different floor finishes or level changes, maintaining proper operation without compromising security.
Older properties often have walls that bow or lean, particularly in mid-terrace houses where structural movement has occurred over decades. The frame specifications for made to measure glass doors can account for these irregularities, ensuring proper sealing and operation despite the uneven surfaces.
Maximum Glass Area
Custom sizing allows for larger glass panels than standard door ranges typically offer. Made to measure glass doors can be designed to use fewer vertical frame members, creating wider views and letting in more natural light. The exact panel sizes depend on factors like glass thickness and frame material strength.
Taller ceiling heights in modern extensions often exceed the maximum heights available in standard door ranges. Made to measure glass doors can span these greater heights while maintaining proper structural support and smooth operation. The ability to specify exact measurements means no wasted space above the frames.
Some spaces benefit from oversized sliding panels that standard sizes cannot provide. Made to measure glass doors can feature individual panels over three metres wide when properly specified, offering panoramic views that would be impossible with standard-sized systems.
Frame Tolerance Challenges
Standard-sized doors rely on adjustment zones built into their frames to accommodate slight variations in openings. These tolerances often prove insufficient for real-world conditions, particularly in older properties. Made to measure glass doors eliminate the need for excessive adjustment zones, as the frames are built to the exact specifications needed.
Made to Measure Glass Door Materials
Frame materials play a vital part in any door system’s performance and appearance. Made to measure glass doors demand specific material properties to maintain stability and operation, particularly in larger installations where standard-sized frames might lack the necessary strength.
Aluminium Systems
Aluminium doors provide exceptional strength while maintaining slim profiles, making them popular for made to measure installations. The material’s structural properties allow for larger glass panels and narrower frames compared to other options, with some systems achieving sight lines under 50mm in width.
Modern aluminium frames feature thermal break technology – a barrier between inner and outer frame sections that reduces heat transfer. The exact composition and size of these breaks vary between systems, with made to measure glass doors often using more robust versions to suit British weather conditions.
Surface Finishes
Powder coating allows for precise colour matching to existing windows or architectural features. The coating process creates a harder-wearing surface than wet paint, with textured options available for period-appropriate appearances. Made to measure glass doors can be specified with different colours inside and out, letting homeowners match interior schemes while maintaining a consistent external appearance.
The anodising process offers an alternative to powder coating, creating a metallic finish that resists corrosion particularly well in coastal areas. The thickness of the anodised layer can be adjusted based on the installation location and exposure levels.
Composite Materials
Recent advances in material science have produced composite frames that combine multiple materials’ strengths. These systems often feature aluminium exterior surfaces with timber interiors, creating made to measure glass doors that require minimal maintenance outside while providing natural warmth inside.
Advanced Made to Measure Glass Door Designs
Specialised door configurations require precise measurements and careful planning. Made to measure glass doors allow for complex arrangements that wouldn’t be possible with standard sizes, particularly when working with unusual spaces or specific architectural requirements.

Corner Systems
L shaped bifold doors create striking openings that wrap around building corners. These systems need exact measurements to ensure proper operation, as even small discrepancies can cause binding or gaps. The corner post design varies based on the desired opening style – some systems eliminate the corner post entirely when open.
Manufacturing corner arrangements demands specialised techniques. Made to measure glass doors for corner installations need precise angle calculations, as few buildings have perfectly square corners. The frame specifications must account for structural loads at the corner while maintaining proper glass support.
Corner installations often need additional structural support above the opening. Steel beams or reinforced concrete lintels must span the corner while supporting the upper floor or roof. The exact specifications depend on the building design and local building regulations.
Split-Level Solutions
Properties with different floor levels between spaces present unique challenges. Made to measure glass doors can bridge these gaps while maintaining proper operation and security. The exact design depends on the level difference and the preferred door style.
Steps or ramps often need building into the door design. Glass doors made to measure for split levels must account for safe passage while meeting building regulations. The threshold design becomes particularly important for maintaining weather protection across different levels.
Water management needs careful planning in split-level installations. Channels and drainage ports must prevent water ingress while allowing proper cleaning access. The exact arrangement depends on the exposure level and local rainfall patterns.
Multi-track systems offer flexible solutions for split-level openings. Different track heights accommodate level changes while maintaining smooth panel movement. The frame design must account for additional forces created by operating panels across different levels.
