Providing, fixing and laying engineers aproved make of bird control spike(100mm) at terraces and other levels as directeed by engineer. PVC/polycarbonate type.

Providing and fixing Acrylic(3mm) make dome fixed with all type of necessary accessories(as per engineers aprooved make): Dynamic dome, curb mounted fixed skylight utilizing extruded aluminum frame counter-flashing with welded corners, structural sealant, and accessories, as required to meet installation and performance requirements indicated. Dynamic dome skylights shall be suitable for installation on roof curbs ranging from 0 degrees up to 60 degrees from horizontal. Dynamic dome designed specifically to harvest the maximum amount of daylight delivered into commercial and industrial spaces at solar elevation angles 10 to 40 degrees. The base of the dome is designed at a 30 degree slope to eliminate reflection, and refract early morning and late afternoon light into the building space. The dome height is 30% of the skylight width in order to harvest maximum levels of daylight at low solar elevation angles. a single white sheet of acrylic glazing material and is certified for air, water, and structural loads. The acrylic sheet has an integrated enhanced spectral protection (UV blocking) that insures long-term color and performance stability.
