Glass Office Partitions London: Systems and Costs

Glass partitions are the most popular way to create meeting rooms, private offices and quiet spaces without losing daylight or the open feel of a floor. We design, supply and install glazed partition systems across London offices, from a single glass meeting room in a Cat A floor to full floor layouts in a Cat B fit-out. The right system depends on how much sound separation you need, the look you want, your budget and what the building and landlord will allow.

Types of glass office partition

Single-glazed frameless. Toughened or laminated glass panels joined with clear or slim joints, held in slim head and floor tracks. Clean and modern, popular for meeting rooms where sound is less critical.

Single-glazed framed. Glass held in aluminium framing, sometimes with visible mullions. Slightly more robust and can include solid panels.

Double-glazed. Two panes separated by an air gap within a deeper frame. Much better acoustic performance and space for integral blinds. Our first choice for meeting rooms where confidential conversations happen.

Fire-rated glass. Special glass and framing to achieve fire resistance where a partition forms part of a protected route or compartment.

Glazed and solid combinations. Partitions that mix glass with solid panels, often to hide storage, screens or services.

How much do glass partitions cost?

The cost per linear metre depends on the system, glass specification, height, door types and site conditions. As a guide in London, single-glazed systems typically cost £350 to £600 per linear metre installed and double-glazed acoustic systems £600 to £1,000, excluding VAT. Our office partitions guide compares all partition types, and the office fit-out cost calculator helps budget the wider project.

What usually costs extra:

• Glazed or solid doors, closers and access control
• Manifestation and branding film
• Integral blinds or privacy film
• Acoustic sealing of the ceiling void above the partition
• Alterations to lighting, sprinklers, air conditioning and fire alarm devices
• Making good to ceilings, floors and walls

Sound insulation: what to expect

Sound performance is often the main reason for choosing one system over another. Remember that a partition is only as good as its weakest point. Sound can travel:

• Over the partition through the ceiling void
• Under it through raised floor voids
• Through door gaps and around frames
• Through ductwork shared between rooms

For meeting rooms, we combine double-glazed partitions with sealed ceiling voids, acoustic door seals and attention to ductwork. See our guide to acoustic office partitions for how acoustic ratings work.

Glass partitions and Building Regulations

Internal partitions in offices must comply with Building Regulations, in particular:

• Fire safety and escape routes: partitions must not compromise fire compartments or escape routes, and may need fire-rated glass.
• Safety glazing: glass in critical locations must be toughened or laminated.
• Manifestation: large glazed areas need visible markings at set heights.
• Accessibility: doors must meet width and opening force requirements.

Our guide to office refurbishment planning permission and building regulations explains when approvals are needed. Most leases also require landlord consent for new partitions, and the landlord may require them to be removed at the end of the lease; see office dilapidations.

Lead times and installation

Installation can often be done out of hours in occupied offices to minimise disruption.

Glass partitions in Cat A and Cat B fit-outs

In a Cat A space, glass partitions are often the first element added to create meeting rooms and offices. In a full Cat B fit-out, they are designed alongside lighting, air conditioning, power and data. Our guide to Cat A vs Cat B fit-outs explains the difference.

Demountable glass systems

Many glazed systems are demountable, meaning they can be taken down and reinstalled elsewhere with little waste. That can help with future layout changes and dilapidations. See demountable office partitions.

Choosing the right glass

Manifestation and privacy

Manifestation can be simple dots or bands, frosted film or branded graphics. For privacy, options include partial frosting at seated height, integral blinds within double-glazed units or switchable glass. These choices also affect how bright the floor feels, so we design them with lighting and layout in mind. For layout ideas, see modern office design ideas.

Glass partitions in older and listed buildings

Many London offices sit in period buildings with cornices, uneven floors and ceilings that are not level. Glazed systems can be adapted with deeper tracks, scribed heads and bespoke framing, but these details add time and cost. In listed buildings, partitions may need listed building consent, and fixings into historic fabric are often restricted. We survey carefully before pricing so these issues are reflected in the quote rather than appearing as extras later.

Cleaning and maintenance

Glass partitions need regular cleaning to look their best, especially around door handles and at the height where people lean. Seals and door closers should be checked periodically so doors close properly and acoustic performance is maintained. Integral blinds in double-glazed units are sealed in and need no cleaning, which is one reason they are popular for meeting rooms.

Glass partition doors

Doors are often the weak point of a glass partition, acoustically and visually. Options include frameless glass doors on patch fittings, framed glass doors with acoustic seals, solid timber doors set in glazed screens, and sliding doors where space is tight. For meeting rooms where privacy matters, a framed door with perimeter and drop-down seals makes a significant difference to sound separation. Door hardware, closers and any access control should be specified at the same time as the partition so everything is coordinated.

How many meeting rooms do you need?

A common mistake is building too few small rooms and too many large ones. Many London offices now need more one to four-person rooms for video calls and focus work, with fewer large boardrooms. Glass partitions make it easy to create a mix of sizes without making the floor feel enclosed. We test the layout against how your team actually works before fixing room sizes.
