The properties of performanceglass shall be decided by technical sanctioning authority as per the site requirement. The rate inclusive of all material charge, labour, transportation, Scaffolding loading/unloading at the work space and removal of debris from Technopark campus etc. complete as per the direction of engineer in charge.

Filling the gap in between aluminium/ stone/ wood frame and adjacent RCC/Brick/ Stone/ wood/ Ceramic/ Gypsum work by providing weather/structuralnon sag elastomeric PU sealant over backer rod of approved quality as perarchitectural drawings at all levels & heights and direction of Engineer-in-charge complete, complying to ASTM C920, DIN 18540-F & ISO 11600 20 (Avg) mm depth and 20 (Avg) mm width or nearest. The work includes removal of the existing or damaged backer rod/ form, and existing sealant and cleaned the gape with proper solution/ equipment (not using the sharp material/ equipment which causes damage to the existing ACP or glass) before applying the backer rod and sealant. Proper Masking tap must be used before applying the sealant to avoid the spreading of sealant around the restricted area and make a better appearance. All the work will be completed per the manufacturer's specification and the direction of an engineer in charge, to avoid the air gap for applying the sealant. The rate is inclusive of all material charges, labour, transportation, Scaffolding loading/unloading at the workspace, removal of spreaded unwanted sealant around the working area and removal of debris from Technopark campus, etc. complete as per the direction of an engineer in charge.
