Service Overview

Glass Partitions

Glass partitions divide offices, studios and home studies while preserving daylight. We design and install fixed walls with sliding or folding doors.

  • Office partitions combine openness with privacy.
  • Home glass rooms separate living, sleeping and work areas.
  • Frosted or clear glass matches your privacy needs.

Clarify three things at measurement: visual or acoustic separation, suspended-ceiling or structural-soffit closure, and joint and door sealing. These determine performance and cost, preventing disappointing sound privacy after installation.

Choosing a style

Seven partition systems and applications

StyleMethodApplications and trade-offs
Frameless butt-jointed fixed wallsSilicone joints with minimal framing.Clear appearance; demanding alignment, weaker acoustic sealing and more difficult single-pane replacement.
Aluminium-framed systemsFrames support glass and accommodate seals.Greater tolerance, acoustic sealing, door and blind options, and potential dismantling and reuse.
Sliding glass partitionsPanels move sideways on top-hung tracks.Save swing space in narrow corridors, but perimeter gaps reduce acoustic performance.
Folding glass doorsMultiple leaves stack to one side.Flexible wide openings; more hardware requires regular care.
Double-glazed partitionsTwo panes separated by an air gap.Improved acoustics for meeting rooms and private offices, with greater depth and cost.
Half-height glazed wallsSolid lower walls with glass above.Screen seated sightlines while preserving light; lower walls conceal wiring and sockets.
Hybrid timber / metal-framed systemsGlass with decorative frames or posts.Match interior styles and provide solid areas for screens or whiteboards.

Coordinate with glass doors and mirror finishes for shared measurements and installation.

Acoustic data

What is Rw? Single versus double glazing

Rw is the weighted sound reduction index in dB, measured in laboratory assembly tests.

Typical laboratory acoustic ranges for partition systems
SystemTypical Rw, dBApplication
10 mm single toughened glass in aluminium framesAbout 28–33.Visual separation and open offices.
12–15 mm single toughened glassAbout 34–35.General room separation.
Acoustic laminated glass, approximately 10.8 / 12.8 mmAbout 36–39.Basic speech privacy.
Optimized single-glazed systems with effective sealsUp to around 40.Higher-demand offices with limited budgets.
Standard double-glazed partitions with air gapsAbout 40–44.Meeting rooms and private offices.
High-specification double glazing with acoustic laminates and optimized cavitiesAbout 45–50; some systems exceed this.Boardrooms and confidential consultation rooms.

What the figures mean in practice

RwIndicative speech privacy
About 25 dBNormal speech clearly audible.
About 30 dBLoud speech clearly audible.
About 35 dBLoud speech audible but less intelligible.
About 40 dBLoud speech difficult to understand.
About 45 dBShouting audible.
About 50 dBShouting barely audible.
Remember: Rw comes from laboratory assembly tests. On-site performance is usually lower than the stated rating because sound travels around the glazing. Assess the complete system: glass, frames, seals, doors, ceiling and floor closures.

For confidential meetings, consider a system targeting Rw above 40 dB while addressing the sound paths below.

Acoustic priorities

Flanking transmission: paths thicker glass cannot fix

Sound often bypasses acoustic glass through gaps elsewhere in the room.

Above suspended ceilings

Partitions stopping at ceiling tiles allow sound across the void. Extend to the structural soffit and seal gaps for acoustic separation.

Doors and thresholds

Doors are often the weakest part: sliding edges and hinged thresholds need effective perimeter and bottom seals.

Floors and underfloor gaps

Uneven floors, raised floors and carpet gaps create paths; seal bases with channels and suitable silicone.

Penetrations and joints

Ducts, cable trays, sockets and discontinuous silicone joints must be addressed individually.

Side-wall junctions

Trim alone does not seal a void between glass and the existing wall; fill and seal the joint.

Over-constrained glass

Rigid clamping increases fracture risk without improving acoustics. Use setting blocks and gaskets for appropriate movement tolerance and sealing.

Glass and privacy

Glass, frosting and film compared

Toughened glass is common; laminated and acoustic laminates improve safety or sound control. Department conditions specify ISO 9001 manufacture and BS EN 14179-1:2016 or equivalent heat-soaking. Barrier-function glazing requires BS EN 12600:2002 Class 1 impact evidence without breakage. Heat-soaking addresses NiS risks also discussed for screens and barriers.

Privacy treatments compared
MethodFeaturesTrade-offs
Acid-etched / sandblasted glassIntegral treatment with uniform, durable appearance.No peeling or bubbles; permanent and generally more costly.
Applied filmPatterns, gradients and stripes added later.Replaceable and economical; edge lifting and durability depend on product and installation.
Mid-height frosted / film bandsScreen seated sightlines.Preserve daylight above and below and provide collision markings.
Tinted glass: grey / bronzeReduce transparency and complement the style.Reduce daylight; consider small rooms carefully.
Switchable privacy glassElectrical control switches between clear and opaque states.Flexible but requires planned power, controls and qualified connection, with higher cost and maintenance complexity.

Processed toughened glass cannot be cut or drilled on site. Locate all door and hardware holes before fabrication using measured dimensions.

Workmanship details

Joints, hardware and doors

Top and bottom junctions

Use base channels and seals, with top channels or trims. For acoustics, extend to the structural soffit and address carpet or raised-floor gaps. Detailing determines performance, appearance and future replacement.

Door choice

Sliding doors save space but have acoustic gaps. Hinged doors with springs or closers and bottom seals suit meeting rooms. See glass door hardware.

Setting blocks and gaskets

Provide tolerance, vibration cushioning and acoustic sealing. Missing blocks can cause rattling during movement nearby.

Mounting and wiring

Do not hang heavy loads or drill processed glass. Plan solid lower walls, plasterboard areas or posts for TVs, whiteboards, sockets and conduits.

Edges and visibility

Polish or chamfer exposed edges to prevent cuts and chips. Mark large clear panels at eye level with bands, film, logos or rails to reduce collisions.

Applications

Office, home and commercial applications

Meeting rooms and private offices

Consider double or acoustic laminated systems, sealed hinged doors and structural-soffit closure. Mid-height frosting or blinds adds visual privacy.

Open offices and work areas

Visual separation may only need single framed glazing. Half-height walls can screen desks and hide wiring.

Home studies and bedrooms

Glass preserves daylight in small homes. Plan ventilation, privacy finishes and space-saving doors. Coordinate with window replacement for airflow and daylight.

Open-plan kitchens

Partitions reduce cooking fumes while keeping views. Use cleanable glass and effective extraction. Required fire compartments need rated barriers, never ordinary glazing; see kitchen fire requirements.

Clinics, salons and studios

Acoustic laminates or double glazing with frosting help speech privacy and cleaning. Address ceiling and floor paths; coordinate salon mirror walls.

Industrial buildings and studios

High ceilings and irregular beams require careful geometry and junctions. Check permitted use, renovation applications and management working hours.

Regulations and administration

Structure, fire safety and consent

Non-structural versus structural work

Typical glass partitions are lightweight and non-structural. Structural-wall changes, slab openings or increased loads need separate assessment. Even works exempt from prior approval under section 41(3) must meet Buildings Ordinance standards. Consult an Authorized Person where uncertain.

Escape routes and fire doors

Partitions must preserve exits, escape routes, door movement and fire-door self-closing. The Fire Safety Code requires rated doors to self-close and remain closed.

Sprinklers, detectors and ventilation

Partitions may change sprinkler, alarm and smoke-control coverage. Consult relevant professionals or registered fire service installation contractors rather than moving devices yourself. Reassess air supply and return to prevent stuffy rooms.

Owner, corporation and management consent

Tenants should follow lease consent and management applications, working-hour and worker-information requirements. Common-area work needs appropriate co-owner or corporation and management consent and DMC compliance. Start administration alongside measurement.

This public-information summary is for reference. Apply Department and Fire Services requirements and the appointed professionals' advice to each case.

Problem diagnosis

Six common partition problems

Sound still audible next door

Check ceiling voids, door seals, floor gaps and penetrations. Thicker glazing alone generally cannot fix these paths.

Rattling glass

Missing blocks or aged gaskets allow movement. Renew cushioning and adjust fixings.

Sticking or misaligned sliders

Clean tracks, replace worn rollers and realign to prevent uneven glass loading.

Yellowed or cracked silicone

UV and cleaning chemicals age sealant. Remove and renew it, checking acoustic leakage too.

Bubbling or lifting film

Poor cleaning, trapped air or damp edges can cause faults. Reapply locally or replace the sheet; consider integral frosting.

Hot, poorly ventilated rooms

Changed supply and return paths need ventilation or air-conditioning adjustments, ideally planned before installation.

Our process

Eight steps from enquiry to completion

  1. Enquiry: call 3709 2164 or WhatsApp 6686 7879 with the room type, approximate dimensions and visual or acoustic separation goal.
  2. Free measurement: check wall alignment, floors, ceilings, voids, doors, sockets, air-conditioning, fire devices and access.
  3. Acoustic target: choose single, laminated or double glazing, soffit closure and door seals.
  4. Design and quote: specify system, glass, doors, hardware, junctions, closures, panel divisions and programme.
  5. Administration: prepare management information and confirm ownership and DMC requirements.
  6. Fabrication: manufacture to measurements with all holes completed beforehand.
  7. Installation: fit channels, frames, glass, blocks, gaskets and doors; adjust hardware and seal joints and voids.
  8. Inspection: check alignment, joints, door movement, rattling and closure completeness, with an indicative listening check and care guidance.

Cleaning and care

Five maintenance priorities

  • Use water or neutral detergent with soft cloths; avoid abrasives on glass and film.
  • Clean sliding tracks and check rollers; address sticking early.
  • Inspect silicone and gaskets for ageing or detachment and check sound leakage.
  • Check locks, handles, fittings and screws for looseness and misalignment.
  • Replace glass with cracks or chipped edges promptly.

Combine checks of door springs, mirror supports and window seals.

Frequently Asked Questions

Glass partition FAQ

30 questions about styles, acoustics, materials, regulations, faults, pricing and care.

Which styles are available?

Frameless, framed, sliding, folding, double-glazed, half-height and hybrid systems. Choose for acoustics, space, mounting needs and removability.

How effective is sound insulation?

Typical laboratory Rw ranges: 10–15 mm single toughened glass 28–35 dB; acoustic laminated 36–39; standard double systems 40–44; high-specification double systems 45–50 or higher. On-site performance is generally lower.

What do the ratings mean?

Indicatively: 25 dB allows normal speech; 30 loud speech; 35 makes loud speech less intelligible; 40 makes it hard to understand; 45 allows shouting; 50 makes shouting faint. Single glazing often cannot deliver confidential meetings alone.

Why can sound pass acoustic glass?

Flanking paths include ceiling voids, floors, door gaps, discontinuous seals, ducts and cables. Complete sealing often improves results more than thicker glass.

Must partitions reach the structural soffit?

For privacy and acoustics, generally yes, with void sealing. Visual divisions may stop at a suspended ceiling at lower cost. Decide before quotation.

Which glass is used?

Toughened, laminated or acoustic laminated, with applicable ISO 9001 manufacture and BS EN 14179-1 heat-soaking. Barrier-function glazing also needs BS EN 12600:2002 Class 1 testing without breakage.

Why is heat-soaking important?

It rejects toughened panes susceptible to NiS spontaneous breakage before delivery, as addressed in the 2018 structural glass code.

Frosted glass or film for privacy?

Frosting is uniform and durable but permanent. Film is changeable and economical but may lift or age. Mid-height bands preserve daylight and screen seated views.

Can switchable glass be used?

Yes, with planned power, controls and qualified electrical connection. Assess higher cost, maintenance and use frequency first.

Sliding or hinged doors?

Sliding doors save clearance but have weaker acoustic sealing. Hinged doors with closers and perimeter and bottom seals usually suit meeting-room privacy better.

Frameless or framed systems?

Frameless gives minimal lines but demands alignment and complicates replacement. Framed systems tolerate uneven walls, accept seals and blinds and may be reusable.

How does glass compare with plasterboard?

Glass preserves light and openness. Plasterboard is economical, conceals services, supports mounting and can achieve better acoustics. Hybrid lower solid walls and upper glass combine benefits.

Can I mount a TV or sockets?

Do not load or drill processed glass. Plan solid sections, plasterboard or posts and conduits for mounting and services.

Does a home glass room affect structure?

Typical lightweight partitions are non-structural; structural-wall changes, slab holes or added loads need assessment. Section 41(3) exemptions still require regulatory building standards. Consult an Authorized Person if uncertain.

What fire-safety matters apply?

Keep escape routes and door swings clear and preserve fire-door closure. Reassess sprinkler, detector and smoke-control coverage with qualified professionals.

Will air-conditioning be affected?

Supply and return paths change. Plan outlets, return grilles, ventilation or separate conditioning to avoid stuffy new rooms.

Is landlord or management consent needed?

Usually lease and management approval applies. Common parts need appropriate co-owner or corporation and management consent and DMC compliance.

How can meeting speech be kept private?

Combine an appropriate acoustic system targeting around Rw 40 dB or above, sealed hinged doors, structural-soffit closure and sealed penetrations. Thick glass alone rarely suffices.

Can glass divide an open kitchen?

Yes, with cleanable glass and sufficient extraction. Required fire compartments must use rated barriers rather than ordinary glass.

Why does glass rattle?

Missing cushioning or aged gaskets allow movement. Add or renew blocks and seals and adjust fixings without rigidly over-clamping glass.

How are ceiling and floor junctions formed?

Channels and silicone secure and seal glazing. Acoustic designs close ceiling voids and underfloor gaps; details affect performance, appearance and replacement.

How are edges made safe?

Polish or chamfer exposed edges and protect them during handling. Chips can initiate fractures, especially in toughened glass.

Should clear partitions be marked?

Yes, eye-level bands, film, logos or rails help avoid collisions in offices, schools, clinics and busy spaces.

Can partitions be moved or reused?

Framed systems are easier to dismantle, but new dimensions limit reuse. Frameless silicone joints risk glass loss on removal. Choose standard, demountable systems if relocation is likely.

Can one pane be replaced?

Usually in framed systems. Frameless joints need careful cutting with some risk to adjacent panels. Match glass and holes and inspect blocks, seals and fixings.

What is checked at measurement?

Walls and corners, floor levels and type, ceiling voids, sockets and switches, HVAC and fire devices, doors and opening direction, lifts and access.

What if large panes cannot reach the room?

Check lifts, corridors and doors first. Increase panel divisions or use framed site assembly where necessary.

How long does installation take?

Measure and confirm first, then fabricate and install. Area, divisions and junction work determine time; businesses often choose out-of-hours work.

How is pricing calculated?

Area, height, system, glazing, doors, hardware, ceiling and floor closures, removal, repairs and working hours determine cost. Free measurement and design quotations are available.
