Glass Partitions – Recommendations for Specifying

Glass Partitions London | 21 August 2019

The specifier might wish to consider specifically how any mock ups or prototypes might be covered at this stage, to allow a more detailed final specification to be written. A specification written in partnership with GH Interior Glass can ensure that key issues and details are considered in the design process, if however a performance specification is going to be produced then the specifier should ensure that evidence can be provided to satisfy them that areas of performance can be met. This is normally in the form of test evidence carried out by an independent test laboratory accredited by ucas. any test evidence should reflect the system and details proposed and where applicable sight of the test report and not just the certification should be made (although copies may not be left for confidential reasons).

specifiers, building operators and facility managers should not accept any substitution of materials from the test report without assessments. In fire, acoustic or applied line load (ie crowd pressure on an escape route) assemblies, any alteration of materials may cause a failure. in line with the National Building specification (NBs) K10 / K30, the design criteria should be given under the following headings (where applicable), together with outline details of layout:

• System manufacturer 

• System type

• Location

• Layout

• System performance

• Fire resistance – BS 476-22(1987) or BS eN 1364-1(1999)

• Fire propagation – BS 476-6(1989)+A1(2009) 

• Spread of flame – BS 476-7(1997) or Bs eN 13501-1(2002)

• Acoustic insulation – BS EN ISO 10140-2(2010) / BS eN isO 140-3(1995)

• Structural – (duty rating BS 5234-2(1) • Strength – to BS 5232-2 grade

• Partition height

• Floor to ceiling (mm)

• Deflection allowance (±mm)

• Panel type – module types

• Solid panels – finish / colour, joint treatment, cover trims • glazed panels – non fire rated and type, fire rated and type, glazing trim / colour, manifestation (to meet the requirements of ad M)

• Junctions

• Framework finish – colour • skirting – colour

• incorporated features:

• Door – type and size, finish, vision panel, ironmongery, overpanel

• Blinds – type, finish

• Accessories – switches

Note that doors can also be included within this specification if they are to perform as part of the partitioning especially in the case of fire rating. they should detail:

• Size including thickness, and clear opening size  

• Description, single / double, single action / double action / sliding

• Edge detail, square rebated, rounded

• Over panel if required

• Performance fire / sound / grade

• Size and position of vision panel 

• Finish, veneer, steel, aluminium glass

• Lippings, exposed / concealed long or all round

• Door frame, stops and architrave

• Ironmongery (schedule) and position on door leaf

• Accessories / door seals intumescent seals, drop down thresholds etc

• Environmental / sustainability requirements eg FSC, peFc, sFi

Glass Partition System Ancillaries

Glass Partitions London | 1 August 2019

BLINDS

Venetian blinds are a popular component used with glazed partitioning. They are mainly used between the glass panels in double glazed elevations, but are also used with offset glazing where space permits. Blinds are supplied in 15mm or 25mm widths and are available either plain or perforated aluminium in a wide range of colours. When choosing a blind, the size of the toprail in relation to the double or offset glazed opening should be considered to ensure that the blind has space to be fitted and be operable.

The blind length can be made to order so that when the blind is fitted and opened, there is no bunching at the bottom. Hold down clips are available to hold the bottom of the blind in place to avoid any twist movement.

In double glazed elevations it is not possible to operate the rise and fall mechanism on the blind, but the opening or closing of blinds can be remotely controlled, or the popular method is by way of a control knob which is fixed to the adjacent partition mullion. a cable fixed to the blind is fed through the partitioning framework to the control knob. On monobloc systems the blind will be installed in the manufacturing process and arrive to site enclosed in the glazed unit.

DOORS

Doors are an integral part of a partition system and are the one element that users interact with daily. It is important that doors are coordinated with the partition manufacturer, especially where sound and fire performance is required. Many partition manufacturers also manufacture doors, so are able to supply doors in structural openings as part of a coordinated interior.

Glass partition doors that are used in the interiors sector include veneer, laminate, continuous pressure laminate, paint grade, steel or glass (as described in 7.4.4). a range of standard widths are available, however, manufacturers will produce bespoke sizes on request. conventional door height sizes are produced as standard as are some full partition height doors but doors with an overpanel are generally made to order. care should be taken when ordering doors with particular handing, figure 36 explain the descriptive methods to be used. It is important that gaps between the door and the door frame are consistent. Best practice would be for a 3mm gap at the top and sides of the door and 3 to 5mm at the bottom of the door depending on the type and thickness of the floorcovering and the underlying level of the floor. Bs 1245 offers guidance on the installation of doors.

Timber doors generally tend to be 35mm or 44mm thick for cellular hollow core doors and 44mm and 54mm for solid core doors. Ideally, all doors should be delivered to site immediately prior to their installation and any packaging material left on the door for as long as possible to avoid any site damage. timber doors should be handled and stored as detailed in Bs code of practice cp151 (Wooden doors clause 501 – storage and protection). Timber door manufacturers and fabricators, as part of their environmental policy, should operate a chain of custody procedure on the timber used in their operation. this involves a commitment to purchase all timber and wood based products from sources that are committed to supply material which originates from sources which offer either Fsc or peFc chain of custody or complies with the Fsc standard for non Fsc certified controlled wood. clear specification as to whether Fsc / peFc material made doors are required on each project should be made and users need to vet their suppliers to ensure that they conform to the chain of custody standards. Glazed vision panels of varying shapes and types can be included in the door specification. this includes matching

HINGES

Fixing height: doors with three hinges should have one centred 250mm up from the bottom of the door, one centred 250mm down from the top of the door and the third centred 450mm down from the top

LEVER HANDLES AND LOCKS

Fixing height: lever handle to be between 900mm and 1000mm above the finished floor level, 1000mm is preferred. Dimensions: not less than 19mm diameter if round section. Not less than 45mm clearance from the rear of the handle to face of door. Not less than 54mm backset from the leading edge of the door. Not less than 72mm centres from the lever handle to key turn.

INDICATOR BOLTS AND TURNS

Fixing height: between 900mm and 1000mm above the finished floor level.

Dimensions: the operating bar of the inside turn should be not less than 45mm long.

SIGNS AND SYMBOLS

Fixing height: 1800mm above the finished floor level except on wheelchair accessible facilities where 1500mm would be more suitable. Dimensions: symbols should not be less than 70mm high. Kicking plates should not be less than 150mm in height.

DOOR CLOSERS

Door closers are used in buildings to self close doors mainly for reasons of security, privacy, acoustics, fire resistance, energy conservation and hygiene. there are essentially three types of closers used; overhead closers, frame concealed closers and floor springs. closers come in two distinct types, uncontrolled and controlled.

Glass Partitions – Add Impact & Improve Your Workspace

Glass has several properties which make it highly valued as a material for interior design. Low cost, completely transparent and strong enough to form a firm barrier, glass is perfect when you want to close off an area without shutting out light and restricting lines of sight. Consider windows. Glass is used in 99.9 per cent of windows because it lets light in, it allows us to see out, it forms a barrier to shut us in from the elements, and it does not break the bank either. A perfect match of material to purpose. The same applies to glass partitions. Glass partitions are basically internal glass walls used to define, close off and demarcate spaces. They are used when you want to differentiate between different areas without shutting in areas in completely.

In modern commercial offices, especially cities like London, square footage and space is at a premium. The cost of expansion is high and the inconvenience of moving is huge. For many, business interruption is too great a risk and thus, any relocation becomes a non-starter.

As an alternative, many business owners are looking to use glass partitioning to break up rooms into more usable and adaptable spaces as a cost effective and flexible solution, with the most popular material in achieving this is being glass. With various options now available on the marketplace, glass partitions not only allow offices to become more adaptable and flexible in their application, they can also bring a whole new look and fresh appeal to what was once a drab and uninspiring interior space. The fact is, glass can really make a huge impact visually and functionally, without breaking the budget.

Here’s just some of the reasons why glass partitioning can be the ideal solution to office space and expansion issues:

1. Lighting

Solid stud walls create a permanent structure that is immovable which can affect the existing lighting of nearby areas, not to mention the new room created. With that, fixed artificial lighting has to be installed to the new area meaning there is no natural light coming in. With glass partitions, this is not an issue. The existing natural light can flood into the newly created partitioned area and reflect light back into other areas where low light existed, thus creating a two-fold benefit.

2. Modernisation

No matter how old, outdated or drab your existing office feels, glass partitions never fail to modernise how a space looks and give it a contemporary feel. And this can really prove to be a huge boost to morale and productiveness in your workforce.

3. Cost

Contrary to what many people belief, glass partitions are actually very cost effective when compared to the investment required to install fixed, structural partitions. With their naturally tendency to insulate and absorb light, rooms using glass tend to be much warmer than people realise.

4. Styles

No two glass partitions are the same! Nowadays, there are various finishes available to give your office a unique look including frosted, tinted and coloured glass, thus making it possible to create customised and branded private areas without cutting off the rest of the workroom floor entirely, even in busy areas.

5. Noise

High quality glass partitions are very good at reducing background noise. With their toughened double glazed structure, they are naturally much better at soundproofing than traditional stud wall partitions.

6. Flexibility

With the help of a professional designer and installer, glass partitions do not necessarily have to stay in any fixed position. Many systems allow them to be moved or slid into different places, making them adaptable to create customised partitioned areas to suit your needs for any given scenario. So your rooms can be either as large or as small as you desire.

Having installed countless glass partitioning systems over the years, I have seen first hand just how much of a positive impact they can have on any commercial space. Glass is a brilliant material for adding impact but it also comes with all of the added benefits mentioned above. It’s a great choice for any office owner struggling to find usable space where they feel they are outgrowing their environment and moving is simply not an option.

If you feel your office is not working for your business anymore, perhaps glass partitions should be your next consideration.

Glass Partitions – Make Your Walls Work For You

Office walls can be so much more than mere walls. You can turn them into a versatile storage system or you can make them come and go as you please. Storage walls and movable walls can make working spaces work even harder.

 

STORAGE WALLS

The most efficient working spaces are clear of clutter, yet everything the team needs to perform at its best is ready to hand. Storage walls include robust workspace partitioning systems that store everything from personal belongings to building plans. There’s no wasted space: wherever you create a room division, that’s where you place your coats, files, coffee makers, and AV equipment. The range of lockers, cabinets, hangers, and shelving units is huge – as is the choice of finishes, locks, turn handles, knobs, and pull handles.

 

MOVABLE WALLS

Wherever people come together for meetings, training, or private functions, there’s a need for flexibility – for spaces that grow or shrink to suit the purpose and the head count. With movable walls you can make any space multifunctional. You can create an interior that instantly responds to rapidly changing commercial and hospitality needs.

 

EXPANDABLE FRAMES

Reduce door and window installation times with ready-made frames. Just fit an expandable frame into the opening and the job’s done. There’s no making good afterwards and no need to finish the actual frame. All fixings are hidden from view.

Industrial Framed Glass Partitions

A contemporary product fulfilling the latest interior design trend for industrial effect glass partitioning. The banded effect has the flexibility of a standard glazed partition whilst providing the visual appearance of industrial split frame installation. This is an easy to use component that helps create a structured, industrial look to frameless glass partitions, a stylish way to compliment any modern office fit out. This style is particularly favoured by creative, media, marketing and PR offices and any other creative businesses. Banded glass partitions compliments buildings original features like brickwork; exposed ducts and pipework; timber beams and wooden floors. It provides an edgy, stylish finish.

The original banded steel windows were a style particularly prevalent in many pre-war houses in the borough of London and still feature in many commercial buildings in the cities across North America. Over the past 30 years they have been considered rather a dated design and, being associated with single glazing, not particularly energy efficient. But as with many interior trends, they have made a serious comeback in both exterior and interior partitioning glazing in the commercial market. And like many resurging fashions, they have been completely modernised in the process.

As commercial working spaces are continually changing and the market supplying internal partitioning and doors has reacted well to these changing demands for a more flexible and transient environment. Interior styling moves too and one of the most recent trends has seen an industrial theme, a style of polished concrete floors and grey walls offering a blank canvas for the design. We have seen exposed brickwork, stainless steel featuring strongly, the mixing and matching of old and new furniture alongside upcycling objects. The new trend in banded glazing has ridden on the back of this styling. It reflects early Crittall® window designs, offering plenty of light to a space with horizontal and sometimes vertical bands separating the glass, adding interest as well as being a great safety feature, allowing people to clearly see the glazed partition area. The styling sits particularly well in commercial buildings that originated in the early 1900s, industrial mills and factories now being regenerated as office space. That said, the trend is also being designed into commercial new build with stunning results.  It’s a form of fenestration that’s currently bang on trend.

This banded trend has added even more design choice to partitions, enabling specifiers to truly personalise a working environment to suit both how a specific organisation works and the building it resides within. In fact the wide choice of styles, colours and materials have now made it quite complex to specify partitioning that’s not only visually on trend but complies to acoustic and fire protection requirements. So it’s important to involve the manufacturer and their product design team when specifying this glazing to ensure it is the right product for the job. Whilst dark grey is currently the prevalent colour option in partitioning, any RAL colour can be sourced; so matching to a scheme or corporate colour way is no problem. To complement these partition walls, both flush glazed and framed glass doors are available in the same styling to continue the banded design. There are also fire screens available to this design, should the project require them.

Banded glass installation

An aluminium frame runs around the perimeter and UVPC bars intersect the glass, giving a framed finish throughout. A dry wall can be built over any uneven surface to prepare your space ready to receive the glass. The glass is then installed much like our other products: as one large pane. The finishing touch of the bars are then assembled on top to give the framed finish.

Banded glass acoustics

The sound privacy level depends on the quality of glass you opt for. The framed banding is best applied to single glazed or acoustic glass.

Doors

A Framed Glass Door is recommended for use with this product to stay in keeping with the industrial style. Handles and locks are also an important choice to ensure continuity in style.

Cost

This cool look comes at a cost as banded glass partitions are usually one of the dearer options. The reason behind the greater cost is that the bars are installed as an additional fixing over the existing glass panels.

Glass Partitions

Glass Partitions for Containing Ambient Noise

Comfortable acoustics can make a working environment more effective and play an important role in employee well-being and efficiency. Effective design and installation of acoustic glazed partitioning has proved key to many successful projects.

In order to understand how best to specify glass partitions, it’s good to start with an introduction to the decibel scale.  This then provides a basis for where on that scale your specification should be. The decibel (abbreviated dB) is the unit used to measure the intensity of a sound. Here are some common sounds and their decibel ratings:

  • Near total silence – 0 dB
  • A whisper – 15 dB
  • Normal conversation – 60 dB
  • A lawnmower – 90 dB
  • A car horn – 110 dB
  • A jet engine – 120 dB
  • A gunshot – 140 dB

How do Acoustic Glass Partitions work?

A thin, clear PVB membrane is bonded to the glass panes. This clever, acoustic membrane absorbs sound energy, preventing the sound vibrations from penetrating the glass, resulting in a significant noise reduction. Glass partitions are acoustically rated according to their performance in laboratory acoustic tests. The resulting figures give an index of performance, which enables one form of a partition to be compared with another, and a particular type of partition to be assessed for a specific application.

Workplace Performance

Laboratory tests are carried out under acoustically optimised conditions. The conditions on-site are very different, and most buildings possess a number of acoustic pathways, or flanking transmissions, which will greatly reduce the sound insulation. Areas of glazing and the insertion of door openings will also reduce the overall performance of the partitions. Typical sources of sound leakage are:

Trunking passing through walls, floors, and ceilings

When installed, the nominal acoustic performance of a glass partition can reduce by 12-15%, even though the installation detailing can be optimised to reduce losses to a minimum. Example: acoustic mastic to abutments, acoustic foam to tracks, thresholds to doors. There are generally accepted acoustic insulation values which when achieved in laboratory test conditions will provide, with appropriate care in installation, acceptable values on site.

The following table provides some general guidance on acoustic privacy in relation to sound reduction:

RwdB Effect

  • 25 Normal speech easily overheard
  • 30 Loud speech clearly overheard
  • 35 Loud speech can be distinguished
  • 40 Loud speech heard but not intelligible
  • 45 Loud speech heard faintly
  • 50 Loud speech and shouting can be heard with difficulty

BS 5234: 1992: Glass Partitions suggests sound insulation performance levels for privacy in some occupational conditions. These are given in the following table:-

  • General offices Rw38dB
  • Private offices Rw44dB

Achieve the best sound quality glass meeting room

Whilst you will not be able to achieve 100% sound insulation there are features that can help you achieve the very best acoustic performance:

  • Double glazed acoustic glass – on top of the acoustic membrane, the double glazing provides an extra layer of glass to help block sound.
  • No door – perhaps you already have another entrance to the room? Choosing not to install a door in will help keep sound within the room, however we appreciate that you need to get in and out somewhere!
  • Seals and frames – if you do need a door, opt for seals and frames to help contain the sound.
