Office Partitioning

Octopus 100 Glazed Partition installation in Grosvenor Street, Mayfair, London W1

We supply and install glass and solid studwall office partition walls.

Our exceptionally popular Octopus 100 and 200 systems offer outstanding value for money, great performance and exceptionally elegant appearance.  10mm and 12mm thick toughened glass within minimal profile aluminium framework results in a stunning single glazed and double glazed partitioning system which looks great and performs excellently in the small office and corporate office alike. The photograph to the right shows one of our Octopus 100 system installations in offices in Mayfair with bespoke natural wenge wood veneer doors and frames.

Additionally, we offer a range of conventional solid studwall systems, budget H-post composite systems, and regular framed single and double glazed systems fitted with standard thickness 6.4mm laminated glass.

Whatever your requirements we have cost effective solutions to suit.  Here are the different types of partition wall supplied and fitted by Octopus:

Studwall Solid Wall Partitions

For the best sound performance (reducing the amount of noise transfer in or out of the room) a solid studwall is amongst the best and most cost effective solutions. We normally use 50mm or 75mm gauge metal studs and 12.5mm thick plasterboards to create walls that have an overall thickness of either 75mm or 100mm, with a cavity of either 50mm or 75mm that is filled with sound insulating quilt for additional sound attenuation. To improve the sound attenuation further still, we would fit two plasterboard sheets on either side (double boarding) thus increasing the wall depth to either 100mm or 125mm dependent on the size of the air gap. For the most elegant appearance, the outer surfaces of the partition is taped, jointed and painted to create a completely smooth surface which blends in seamlessly with the core walls of the building. Where flexibility, cleanness and speed of installation is required, we fit the Tenon Fire & Sound or Fastwall aluminium framed partition systems.   Both of these systems can also be fitted with single and double glazed sections.

Frameless Glazed Partitions

Minimal framework glazed systems are usually referred to as frameless systems. Our products are the Octopus 100 and 200 systems described earlier.  This system uses a very slim profile aluminium channel or track along the floor, ceiling and walls, just sufficient to hold full height sheets of 10mm and 12mm toughened glass in place.  The sheets of glass are bonded together along their vertical edges with a clear silicone compound negating the need for chunky intermediate vertical metal framework found on other systems (hence this system is often referred to as “frameless glass partition”).  The doors are usually glass and normally have no frames, and although aluminium door frames are available to provide a better sound seal they tend to detract from the elegant lines of the system.  Full height solid core wood veneered or laminate doors can be fitted in place of glass doors within aluminum or wooden frames if required.

The photograph to the right shows one of our Octopus 100 single-glazed partition installations within a listed period building in Westminster. This was a relatively tall ceiling height of 3.2 metres and we used 12mm thick toughened safety glass in this installation.  Health and Safety regulation requires manifestation film or frosting to be applied to the glass and as a minimum this is typically a couple of rows of dots, squares or continuous lines, but can also be made into an attractive design feature to further enhance the appearance of the glazed wall and also to provide visual privacy. Manifestation designs are endless and can include colour, company logos and slogans, images and much more.

Compared with other types of partition, this system is amongst the quickest and cleanest to fit, and causes least amount of disruption to your business if it has to be installed within an occupied and operational office. It is also the quickest and cleanest to remove when you need re-configure or move out of your office.

Framed Glazed Partition Systems

Conventional glass partitions are generally in framed sections or modules typically fitted with 6.4mm laminated glass.  We offer the Tenon Fire & Sound and Fastwall systems, both of which can be fitted with single glazed, double glazed or part-glazed part-solid sections. The glazed sections may be fitted with integral venetian blinds or have a frosting or manifestation film design applied. The aluminium frame is available in a range of colours, white, grey and SAA being the most popular.

The photographs to the left and right show installations in offices in London of our double glazed Tenon Fire & Sound partition. Both of these are finished with different designs of manifestation frosting film and SAA (silver anodized aluminium) framework was used.

 

50mm Aluminium H-Post Partitions

For low budget installations where appearance and sound attenuation is of less importance, we offer the Tenon Flex-Plus system, an aluminium H-Post system with 50mm thick plasterboard faced honeycomb panels. Quick, simple and relatively clean to install at an affordable price. This system is also available in single and double glazed, or part-glazed configurations.

Read on below to see which type best meets your needs.

 

Choosing the most suitable partition for your office.

There are 5 main factors that you may need to consider which, in no particular order, are as follows:

  1. Sound Performance
  2. Light Transfer
  3. Appearance
  4. Cost
  5. Speed & Cleanness of installation

Sound performance:  Many partitioning systems and the materials used in the construction of them have been tested to establish their sound-rating (the effectiveness in absorbing or preventing the transmission of sound). This is usually given in decibels (dB), and might also be shown together with the letters Rw which signifies that it is a rating for the sound insulation of building elements which includes a weighting for the human ear and measures actual sound transmittance. The table below below shows the approximate typical Rw ratings of common/standard types of office partition, however it is important to understand that the tests that produce these figures are carried out in laboratory conditions and when installed in a typical office environment the sound attenuation properties may be lower due to sound leakage via gaps created by suspended ceilings, air conditioning vents, raised access floors and even doorways.  So, these figures should be used to show the relative performance of one type of partition against another, rather than exactly how they might perform in your office. The higher the dB value, the better the sound insulation is.

Solid Studwall, double boarded with quilt cavity insulation 48dB
Double Glazed with combination of 12mm and 10mm silicone jointed toughened glass 43dB
Solid Studwall, single boarded with quilt cavity insulation 42dB
Solid Studwall, single boarded without insulation 38dB
Double Glazed aluminium mullion system with 6.4mm laminated glass 38dB
Single Glazed with 12mm silicone jointed toughened glass 35dB
Single Glazed with 10mm silicone jointed toughened glass 33dB
Single Glazed aluminium mullion system with 6.4mm laminated glass 30dB
Solid 50mm H-post system with plasterboard faced honeycomb panels 29dB

 

The above figures are approximate and assume standard materials are used.  With specialist acoustic glass (e.g. Stadip Silence glass) or other specialist insulation materials, improvements can be made. But what do these figures actually mean?  Well, they’re average weighted figures calculated over a wide range of frequencies. Each type and thickness of material (glass and plasterboard in this case) is susceptible to a particular frequency at which it resonates the most and becomes least effective as a sound blocker. This varies from material to material, but tends to be in the low frequency range below the level of normal human speech – e.g. the sort of noise you get from from traffic, the drone from building heating and plant machinery, music bass and so on.  What this means is that a glass partition, for example, is likely to be less effective at insulating the sound of a music bass track at a given volume (decibels) than it would a normal conversation at the same volume or decibel level. Because the Rw figures take a weighted average which include the lower frequencies, it is reasonable to assume that if your main concern is in having an office partition which gives speech privacy (i.e. that people outside the room can not hear or clearly discern the content of a conversation occurring inside), then the dB figures probably don’t properly reflect its sound absorption properties for the purpose you require it for.  For typical speech only values, you can perhaps add a few decibels onto the Rw figures.
