Concealed Grids
Clean Room Ceilings
Burgess plain (unperforated) Clip-In tiles are ideal for use in areas requiring a high degree of cleanliness such as laboratories and hospital operating theatres.
A totally air and dust tight ceiling can be achieved by using plain (un-perforated) bevel edged tiles with a silicone sealant applied between the joints of the tile.
A bead of silicone can be applied onto the rear face of perimeter trim to provide a complete seal between the cut perimeter tiles and the trim.
Should access to the ceiling void be required, this is achieved using a sharp knife along the tile joints to break the silicone seal. The tile can then be removed using a vacuum lifter or blade extractor and once the tile is replaced the seal must be reapplied around the tile.
Ceiling type:
Clip in concealed grid metal suspended ceiling.
Access:
Full access to the ceiling void is achieved once mastic sealant is removed.
Ceiling Module:
600mm
Suspension system.
Burgess H4 concealed grid system comprising primary grid section ref: GT112 suspended from the soffit at 1500mm maximum centres by galvanised mild steel angle hangers ref: GT114. Hangers to be secured to primary grid using M6 or equivalent fixings. 45mm wide x 29mm deep x 0.8mm thick galvanised mild steel Spring Tee bars, ref: GT115, to be connected to the primary grid using niversal Bracket, ref: GT109, at centres corresponding to tile length.
Perimeter trim:
Burgess aluminium channel trim section (ET181), complete with hold down wedges (GT120) to ensure maximum hold down coverage.
Infill units:
Burgess zinc coated steel polyester powder coated ceiling panels, bevel edged type A, plain. After the tiles have been installed a thin seal of silicone is to be inserted between the tiles thus ensuring a totally dust free environment. Excess silicone is to be wiped free allowing the bevel edge to remain clear of it. The ceiling tiles are to be wiped clean with a soft clean cloth, warm water and mild detergent in the event of hand marks during installation.
Tiles to have factory formed apertures for services where required. For recommendations regarding additional loading on the ceiling system please contact the Burgess Technical Department.
In the event of tiles being removed for access to the void, the mastic seal should be broken using a sharp knife along the tile joint. A vacuum lifter should be used to remove the tile from the spring tee bar. When replacing the tile, ensure that the pips locate into the tee bar to obtain the corrective level. Mastic sealant should be re-applied to all edges of the tile as stated previously.
