Locks can be operated with a square shanked key (budget locks) or, in particularly sensitive areas such as police stations or prisons, the locks can be key operated (Yale Type). Where Yale type locks are specified and there are numerous access panels required in a ceiling the keys can be “suited” such that the same key operates all of the panels if that is desired.

High Humidity Ceilings
AGGRESSIVE ENVIRONMENTS Burgess Clip-In tiles are available in a variety of finishes for use in more aggressive environmental conditions. Shower Areas For these areas we would recommend plain bevel edged Clip-In tiles with a Plastisol finish with a silicone sealant applied between the joints of tiles. Perimeter channel trims should be aluminium or painted stainless steel. Swimming Pools Plastisol finish plain Clip-In tiles are also suitable for use in areas such as swimming pools and changing rooms. Kitchen Areas For areas where normal humidity levels do not exceed 70% and adequate extract systems are in place a plain polyester painted Clip-In tile is recommended. Plastisol finish tiles should be used where humidity levels are high or where there is poor heat extraction. Tiles above direct heat sources should be well ventilated to ensure surface temperature does not exceed 60ยบC to avoid surface finish blistering. Food Preparation Areas Where a smooth frequently washable ceiling is required rather than the slightly textured finish of Plastisol, Burgess can provide plain Clip-In tiles in a Stelvetite Foodsafe finish. A silicone seal between tile joints can be used if the ceiling is required to be watertight.
For added confidence in food display or food preparation areas, a powder coat formulation is available with proven anti microbial performance to inhibit bacterial growth.

Clean Room Ceilings
Burgess plain (unperforated) Clip-In tiles are ideal for use in areas requiring a high degree of cleanliness such as laboratories or 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, the seal can be cut along the tile joints and the tile can then be removed using a vacuum lifter or blade extractor. Once the tile is replaced the seal can be reapplied.

Lay-In Tiles
The term lay-in refers to tiles that have minimal tile face coverage by the supporting exposed grid as distinct from lay-on tiles where the face of the tile is fully visible. Lay-in tiles are used with exposed grid table usually 24/15mm wide although different grid table widths are available. These can be supplied in a range of standard sizes shown below or tailor made to suit a particular application. Where lay-in perforated tiles are required it is recommended that the supported edges of the tile are perforated and the un-supported edges (usually the long sides) have plain borders. This arrangement provides the appearance of a plain border edged tiled ceiling with the exposed table grid providing the border on the supported edges. The grid is supported by GT114 hangers at 1200mm maximum centres in both directions.

Nilgrid
The Burgess Nilgrid system is designed to solve the many problems associated where services are concentrated in the corridor ceiling void and when easy and frequent access to these services is required. Ideally suited to hospital environments, the panels span from wall to wall with no intermediate fixing. Planks are offered 300mm wide and can be manufactured in any length up to a maximum of 2400mm. Special perimeter sections deal with minor variations in the width of the corridor. The planks are hinged at one end and can be accessed by one person. When opened the planks hang against the wall, so affording the maximum amount of access.

Fire Performance
FIRE RESISTANCE – BS476 Part 8. Within this British Standard, fire resistance is defined as the level of protection given to structural steel beams by the suspended ceiling below. In accordance with the above British Standard, a Burgess ceiling fitted with mineral wool insulation pads was constructed within a concrete and steel framed furnace. Heat was applied from below up to a temperature of 1000ºC and the temperature of the steel beams recorded by thermocouples until the temperature reached 400ºC. The time taken to reach this temperature defines the level of fire resistance achieved by the ceiling. In a test carried out at the Fire Research Station the Burgess Clip-in metal ceiling system achieved a 1 hour fire rating in accordance with this standard. Test Certificate FROSI No.6487. FIRE RATING WITHIN THE VOID The normal fire resistance rating applies to protection of steel beams behind the ceiling. There is also a requirement for some ceiling systems, particularly escape corridors, to provide a half hour fire rating from within the void itself. To achieve this, additional insulation material is required above the spring tee bar to protect the grid from the effects of a fire within the void. We would advise that an independent fire officer be consulted where this requirement is specified for the ceiling system. SURFACE SPREAD OF FLAME – BS476 Part 7. This British Standard test measures the lateral

Spread of flame along the surface of a product when a pilot flame is applied to one end of the sample. The classifications for flame spread range from Class One (being the highest) to Class Four (being the lowest). To comply with Class One the extent of the flame spread is limited to a maximum distance of 165mm from the heat source. Burgess ceiling tiles have achieved a Class One rating when tested in accordance with this standard at Warrington Fire Research Centre. Burgess conducted their Surface Spread of Flame testing with insulation fitted into the back of the tile. FIRE PROPAGATION TEST – BS476 Part 6. This British Standard test measures the heat released from a product so that an assessment of its possible performance in a real fire situation can be made. Burgess ceiling tiles have been tested at Warrington Fire Research Centre and achieved a Fire Propagation Index, I = 1.2 Building Regulations In accordance with Appendix A paragraph A12(b) of Approved Document B 'Fire Safety' to the Building Regulations, products are designated a further fire performance classification relative to their performance against BS476 Parts 6 & 7. Products meeting the requirements of Class 1 to Part 7 and having a Fire Propagation Index (I) of not more than 12, and (Ii) of not more than 6 are designated Class O. Burgess ceiling tiles comply with the requirements for Class O.

MARINE & OFFSHORE FIRE RATED CEILING SYSTEMS Burgess offer Clip-in Tile systems for use in both Marine and Offshore installations. Clip-in 600 x 600mm Stainless Steel tiles are available for use in aggressive/high humidity areas such as galleys, together with painted tiles for other areas. FIRE RESISTANCE TESTS – Marine Fire resistance tests for the latest International marine applications have also been completed to IMO A.754(18) / A-30 / B-15 ceiling standard. This is a very stringent test to ensure the metal deck above the suspended ceiling membrane is sufficiently protected to ensure the deck remains integral and in service for a period of time in the event of a fire. The tests are divided into two categories namely A and B. Category A certification requires that the suspended ceiling remains integral and that decking temperature above the suspended ceiling does not exceed 180ºC. Category B certification requires that the suspended ceiling remains integral and that the temperature of the decking above does not exceed 225ºC. These tests are more demanding than their equivalent BS476 requirements, which reflects the importance of the ceiling membrane in the protection of metal decking above the ceiling in marine applications. Burgess Clip-In ceilings have achieved A30, B-15 ratings in accordance with the requirements of this standard.

1. STORAGE Burgess standard tiles are generally packed in cartons, which must be stored no more than four cartons high. They must be stacked the correct way up as stated on the side of the carton and must be kept in a dry storage area. Particular care should be taken when moving cartons by hand as weights of cartons will vary dependant upon the size and type of tile. To assist in safe handling, size, type of tile and the weight of each carton is clearly displayed as part of the carton labelling. 2. HANDLING Immediately after installation of the ceiling, we would recommend that any dirt or finger marks be removed with a clean dry cloth. Particular care should be taken with low gloss tiles, as finger marks are more difficult to remove. Continual rubbing of the surface of low gloss tiles can cause an increase in gloss level. To prevent finger marks, the use of soft cotton gloves is recommended during handling and installation of tiles. Care should be taken when handling cut tiles and gridwork where sharp edges may be left - personal protection equipment should be used as appropriate at all times . 3. CLIP-IN TILE REMOVAL
the tile. The tile can now be removed in a controlled manner. With longer planks, you may require the assistance of a second person. 5 To replace the tile, offer the edge of the pipped and stopped flange of the tile into the spring tee bar. Working at the corners, push the tile into the tee bar until the pip engages into the bulb of the tee. If necessary place a cloth-covered block on the corner and tap home the tile. To avoid fingermarks it is recommended that a pair of clean cotton gloves be used for the above maintenance operations. A limpet vacuum lifter (GT 135) can be used to remove nonperforated tiles in a similar fashion. 4. METHOD OF CLEANING The following method of cleaning is suggested: 1. Add some all-purpose liquid cleaner to a bucket of hot water (Quantity as recommended by manufacturer) 2. Immerse clean cloth and wring out (the cloth should be damp). 3. Wipe entire surface area of the tile. Do not attempt to cover large areas without continually rinsing cloth. 4. Wipe over with a chamois leather. Please note that on no account should an abrasive detergent powder be used. Where ceilings have been left for a number of years without cleaning or have been subjected to significant staining, it may be necessary to employ the services of a specialist ceiling cleaning company. 5. SITE WORKING / CUTTING Where tiles must be cut on site, at perimeters for instance, then this can easily be achieved using suitable hand or power tools. For long straight or curved cuts, we would recommend the use of electric metal shears. Circular or rectangular apertures can be formed with either tin snips or electric metal shears, with sheet metal punches being more appropriate for small diameter circular holes. Electric metal shears can be operated with one hand, giving distortionfree cuts that need no edge finishing. Raw edges in external applications must be treated.
The method of extracting Burgess Clip-In and Swingdown tiles using the blade extractor tool (product No. GT137) is as follows: 1 Establish the direction of the spring tee bar. Where rectangular tiles are used, the tee bar normally runs along the short sides of the tile. For square tiles, the spring tee bar generally runs lengthways down the room. 2 Insert the blade extractor at a slight angle between the tile joints, approximately 50mm from the tile corner, with the hook of the blade facing the tile to be removed. 3 Push in the blade until it touches the top of the spring tee section. Move the handle to the vertical position. You should hear the hook click over the top of the tile flange. 4 Pivot the blade against the top of the tee section by moving the handle to an angle and the tile should start to come out. Do not pull blade directly down. A 5 or 6mm movement will free the pip from the bulb of the tee. Repeat the process on the parallel corner of
6. RE-DECORATING Where required, air-drying touch-up paint can be supplied to make good small areas of damage to the paint finish. However, we do not recommend over-painting of tiles or trim due to the possibility of intercoat adhesion problems.

Lengths of suspension channel are to be joined with channel couplers (GT113) using M6 fixings. Allowance for expansion is to be made as necessary. Setting out from the centre of the room, locate beam support brackets into beam grid at 1500mm maximum centres and offer up to the suspension channel at the appropriate centres. Beam support brackets are located over the suspension channel and the top leg is folded along the pre-formed slot. The bracket is then secured to the channel using self-tapping screws, or similar, at module centres. Lengths of beam grid are to be joined using splice plates and allowance for expansion is to be made as necessary. (*Install cross beams at appropriate centres, securing each end to main beams to provide rigidity and maintain module. Tiles can now be offered into place. (At least every fifth tile secured to the Linear Beam grid to provide system rigidity). Where no suspension channel is being used, spacer bars are to be installed at 1500mm centres to maintain beam module. Cut perimeter tiles must be retained using wedges (GT120) spaced at 300mm maximum centres.
Using a laser, or equivalent, determine ceiling level and secure perimeter trim (GT119) to the wall at 450mm maximum centres. Cut lengths of suspension angle (GT114) to suit suspension depth ensuring sufficient length for fixing. Secure angle hangers, at 1200mm maximum centres, to the structural soffit using fixings approved by the Architect and determined by load and safety factor considerations. The first hangers are to be no more than 300mm from the wall. Using M6 or equivalent fixings, secure suspension channel (GT112) to the angle hangers, taking care to maintain a perfect level. Underside of channel to inside face of trim = 45mm for Type A tiles, 38mm for Type C tiles. Each end of suspension channel runs to be folded back and secured to wall. Lengths of suspension channel are to be joined with channel couplers (GT113) using M6 fixings. Allowance for expansion is to be made as necessary. Setting out from the centre of the canopy, secure full tee bars (GT115) to suspension channels using universal brackets (GT109), at centres to suit tile modules. Where possible, not less than half tiles should be used at perimeters. Universal brackets are located over the suspension channel, the top leg is folded along the preformed slot and the bracket then secured to the channel, using self-tapping screws or similar, at module centres. Lengths of full tee bar are to be joined using tee bar couplers (GT116), secured with M6 or equivalent fixings, and allowance for expansion is to be made as necessary. Tee bar joints to be made ‘mid tile’, i.e. not on the tile joint lines. Tiles can now be clipped into place, taking care that the pips are correctly located into the bulb of the tee bar. Where the canopy is subject to wind loading, security clips must be fitted to secure each tile to the tee bars. Cut perimeter tiles must be retained using wedges (GT120) spaced at 300mm maximum centres.
Check corridor widths to ensure panel length and flash gap are suitable for installation as shown on layout drawing. Using a laser, or equivalent, determine closure angle level and mark on wall. Mark positions of NIL 5 brackets @ 1.2m centres and secure, finger tight, to wall. Drill holes in 25mm leg of closure angle @ 450mm maximum centres and secure to wall. With NIL 5 resting on closure angle, mark through the lower hole on back of NIL 5 and secure to wall. Alternately relax and tighten brackets to set NIL 5 in true horizontal plane. Drill M6 clearance holes centrally in top of NIL 1 profiles at 1.2m centres and slide in 12 No. NIL 3 cleats. Secure NIL 1 profiles, finger tight, to NIL 5 brackets using M6 dome head set screws, nuts and spacer washers. Set NIL 1 to correct distance from wall, align all lengths and tighten fixings. Drill M6 clearance holes in top flat of NIL 2 profiles at 1.2m centres to align with slots on NIL 5 brackets and secure, finger tight, with M6 set screws, nuts and spacer washers. To set spacing of NIL 1 and NIL 2 profiles, temporarily fix one NILGRID panel every 1800mm along corridor. First locate NIL 4 collars on to two adjacent NIL 3 cleats and offer up the pivot end of panel. Install panel vertically by locating side flange holes over NIL 4 collars and install split pins through NIL 4 collars and NIL 3 cleats. Adjust position of NIL 2 profiles by offering up the release end of panel until it locates into the NIL 2 profile. Tighten all fixings to NIL 5 brackets and secure 9.5mm outer lip of NIL 2 profile to NIL 5 brackets with self-tapping screws. Using ceiling layout drawings fix the setting out point by ‘locking’ a NIL 3 cleat, with self-tapping screws, to flat top of NIL 1 profile. Repeat at every fourth NIL 3 cleat. Facing the Pivot Wall, commence panel installation from the left-hand end of the corridor. End Wall panels are cut to size and located into NIL 1 profile, secured to the wall @ 450mm maximum centres, using Odd Leg channel wedge, GT122. Remaining NILGRID panels can now be hung generally as described above. Installation is completed by offering up the release end of panels and locating into the NIL 2 profile. Tiles with integrated luminaires should be non-pivoting and fixed to the NIL 2 profile with self-tapping screws.
