Glass doors

Contact us

    Looking for elegant, secure and energy-efficient glass doors for your home? Our residential range pairs perfectly with our glass extensions, glass links and glass roofs, creating light-filled spaces with uninterrupted views and seamless indoor-outdoor living.

    Why choose GSL for your home?

    As a UK manufacturer-installer with deep in-house engineering, we design, make and fit bespoke systems for period homes and contemporary builds alike. Our sliding systems deliver ultra-slim 20 mm sightlines for maximum daylight and views, with U-values from 1.3 W/m²K (and lower with enhanced glass), multi-point locking and Document L/Q compliance. Typical lead times start from 4–6 weeks depending on configuration.

    Door types we offer for residential projects

    • Minimal sliding glass doors (GSL COR): Thermally broken aluminium, low-maintenance powder coat, 1–4 tracks (up to ~80% clear opening), moving corners, flush tracks and automation options—crafted for expansive openings with crisp, minimal frames.
    • Ultra-slim sliding doors (GSL 20): Equal 20 mm sightlines around, panel sizes up to 4.2 m wide or 3.2 m high (≤ 9 m²), PAS 24:2016 and Secured by Design compliance options—ideal when you want scale without visual bulk.
    • Steel and steel-look heritage doors: Authentic slim-profile steel (or steel-look) for classic aesthetics with modern performance: thermal profiles from ~1.2 W/m²K, acoustic insulation up to ~47 dB, hinged, sliding, tilt-and-turn configurations. Great for feature entrances, internal screens and garden rooms.
    • Alitherm Heritage doors & windows: Smart-profiled thermal break technology engineered as a direct steel replacement—suited to listed buildings and refurbishments, with testing to PAS 24, BS 6375 and BS Kitemark certifications.

    Designed for real homes

    Whether you live in a period townhouse, a countryside cottage or a contemporary new-build, our residential glass doors are tailored to your property and the way you use it. We design every set to complement neighbouring elements like glass extensions, glass links and glass roofs, creating a coherent, light-filled home with effortless flow between rooms and out to the garden.

    For character homes, we balance modern performance with sensitive detailing—slim profiles, heritage-friendly sightlines and finishes that respect original fabric. For contemporary spaces, we engineer large panes, clean junctions and minimal frames that keep views uninterrupted and thresholds near-flush for easy access.

    Every specification is bespoke: sizes, opening configurations (single, double, multi-track, pocket or moving-corner), hardware, colours and glass types are selected to suit your architecture, lifestyle and maintenance preferences.

    Popular residential options

    • Safety first: toughened/laminated glass, child- and pet-friendly low thresholds.
    • Privacy on demand: satin/obscure glass, switchable privacy glass, integral blinds.
    • Daylight control: solar-control and low-E coatings to reduce glare and heat gain.
    • Seamless finishes: powder-coated frames (standard and bespoke RAL), concealed drainage, flush/recessed tracks.
    • Smart living: automation, soft-close, integration with home-security systems.

    Performance & comfort

    Our doors are engineered for year-round comfort. Thermally broken frames, high-spec insulated glazing and quality weather-seals help stabilise indoor temperatures while maximising natural light. Where security is a priority, we can specify laminated panes, multi-point locking and hardware tested to recognised UK standards (including PAS 24 options).

    Acoustic comfort matters at home. Glass make-ups and gaskets are selected to dampen traffic or neighbourhood noise without compromising the slim aesthetic. For sunny elevations, solar-control coatings and shading strategies reduce overheating and glare while maintaining clarity and colour neutrality.

    Ventilation and condensation control are designed into the package: optional trickle vents, warm-edge spacers and carefully detailed interfaces help the system breathe, protecting finishes and improving overall energy performance.

    What you can expect

    • Stable indoor temperatures with insulated frames and glazing.
    • Smooth, quiet operation thanks to precision rollers and balanced sashes.
    • Reliable weather protection from high-quality seals and drainage detailing.
    • Security peace of mind with robust frames and multi-point locking (PAS 24-ready when specified).
    • Lower maintenance through durable powder-coat finishes and easy-clean glass options.

    Installation & timelines

    A residential project should feel organised and predictable. We manage the process end-to-end—design, manufacture, installation and aftercare—so you have a single accountable team.

    How we work

    1. Consultation & outline quote — discuss openings, styles, performance goals and budget.
    2. Site survey — precise measurements, threshold strategy and structural checks.
    3. Design & approvals — CAD details, glass build-ups, hardware schedule; final sign-off.
    4. Manufacture — frames, panes and hardware produced to your specification.
    5. Pre-install prep — coordination with your builder on apertures, power, drainage and finishes.
    6. Installation — delivery, setting frames, glazing, sealing and weathering details.
    7. Commissioning — alignments, lock checks, automation setup (if included), quality control.
    8. Handover & aftercare — maintenance guidance, cleaning tips and warranty documentation.

    Typical timings

    Lead times for residential sliding sets commonly start from 4–6 weeks after design sign-off, depending on configuration, finish, glazing complexity and automation. Bespoke colours, shaped panes or specialist glass may add time; we’ll advise early so your programme stays on track.
