Module 4 – LaGyp Exposed Grid Ceiling System – 28-01-2009 – Rajat Tanwar 09983544430 Module - 4 LaGyp Exposed Grid Ceiling Training Manual INTRODUCTION LaGyp Exposed Grid Ceiling Systems are typically for commercial and domestic applications which require aesthetic ceilings but can also provide acoustic absorption and easy to clean if required. In addition to this they also provide easy access to the mechanical and electrical services above the ceiling. This makes the system ideal for areas inside buildings like production areas in factories, offices, meeting rooms, shopping centres etc. The Exposed Grid Ceiling System comprises of LaGyp ceiling tiles dropped into a LaGyp Suspended Exposed Gird frame.

Module 4 – LaGyp Exposed Grid Ceiling System – 28-01-2009 – Rajat Tanwar 09983544430 Module - 4 LaGyp Exposed Grid Ceiling Training Manual LaGyp Exposed Grid Ceiling – Installation Step 1 – Water Levelling Fill the Pipe by pure water from an elevated bucket, and let the water flow long enough to force out the air bubbles. If both ends line up, youre good to go. Test the accuracy of the level by holding both ends together. If the water levels dont line up, youve got air bubbles trapped in the line. If you cant get the bubbles out by tapping the line with a finger, the best thing to do is empty the hose and refill it. V marks the spot. Draw a prominent Vshape over a straight line to indicate the precise elevation. (Note: Because the surface of the water in the tube is slightly concave, both workers should agree beforehand on whether to mark the high point or the low point.) One person calls the shots, and the other works the room. After establishing a benchmark in a convenient corner, one worker remains at that location with one end of the pipe (inset photo) while his partner heads for the nearest corner with the opposite end and a pencil. The first worker slowly moves the tube up or down until the surface of the water aligns with the benchmark. After pausing for a few seconds to verify that the water has stopped moving, he gives his colleague the OK to mark the wall. Create a level field and worry about the height later. In many situations, its easier to pick an arbitrary heightpreferably at eye leveland use the water level to place a reference point in each corner. Once these benchmarks are in place, a tape measure can be used to lay out the correct height quickly.

Fix the Perimeter Channel to walls and around columns etc at 600mm maximum centers. To fix Hangers Mark Position on the ceiling. First marking will be done at a distance of 200 mm Vertically from the wall and then at a distance of 1200 mm. Fix the Hanger to the ceiling using the Soffit Cleat and Expansion Fixing (Hilti)

Hang the Main Channel with the Hanger at a distance of 1200 mm from the wall Now fix Cross T Runner with the Main Runner at a distance of 600 mm from wall and center to center Fix the ceiling tiles on the 600*600 mm frame. Be careful while installing the tiles as the edges of the tiles will easily be broken due to miss handling Always wear clean gloves when installing LaGyp Ceiling Tiles to ensure ceiling tile are kept clean and free from finger marks
