The sheet glass shall be toughened of thickness 5mm. The wire mesh shall be of stainless steel stainless 0.36mm nominal dia of wire and average width of aperature 1.40 mm. After fixing the frame the gap between the frame and adjacent finished wall shall apply Silicon sealant to make joint, water proof of approved quality. There would be a conditional warranty of minimum 10 years on profile & 02 years on hardware from the date of completion. The uPVC system must be installed by profile manufacturer or their authorised agents only complete all as specified and as directed by Engineer-in- charge. (Note :- The rate of 5mm thick toughened glass for glazing and stainless steel wire mesh cloth 0.36mm nominal dia of wire and average width of aperature 1.40 mm is included in this item and nothing shall be paid extra on this account. Net opening will be measured for payment purpose.)
