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
