Supply and installation of 70 mm thick magnesium oxide board drywall Tufbloc parition system having (high water & fire resistance) Which includes two layers of tufbloc magnesia square board having square edge & size 2400 X 1200 x 10 mm to be fixed on the either side of the GI stud channel framework in horizontal position of length side board. Now the frame work includes Floor / Head ( FC 50) channels having thickness 0.06 mm length 3600 mm equal fanges of 32mm & web of 50 mm fixed to floor & ceiling with suitable fasteners at 300 mm center Staggered noise & fire rated silicon sealant to caulked along the perimeter of the partition frame before fixing channels. Then stud channels SC 48 having thickness 0.75 length 3600 mm, un equal flanges of 36 mm & web of 48 mm should be placed into the floor / head channels positioned vertically at 600 mm centers. Horizontal intermediate channel at 1200 mm centers to locked with the vertical Studs. Extra reinforcement to be provided at openings (doors & Window), Apply Synthetic poly fiber 10 x 25 is 50 mm width 600/1200 mm density 1000 gsm filled between the studs & held in position by using Chicken mesh wire / pasting on the board. Now boarding is to done on each side of studs framework in a staggered pattern by the help of self drilling screw at 300 mm centers. After boarding of two boards jointing & finishing is to be done by joint compound. The flush look will appear after sanding the two boards joint property to get a smooth look. The technical parameters of the boards - Density- 1000 kg / mt cube weight 10 kg/ mt sq. Fire -150 min acoustic STC - 50 db, climate OCRH - 50,99 Termite resistance - yes, Moister absorbent - 6.8% after 2 hr, wet expansion less than -0.02% from ambient to saturation Moister Movement - 0.02% Green - RC % - 30 Strength - Anti sag. Test reports of manufactures are to submitted at the time of delivering of materials.
