| The system is installed in such a way that the light guidance component of the system is dustproof. This is necessary to prevent dust from entering the tube to ensure reflectivity is maintained. It is also to ensure that the air column inside the tube will act as an insulator for heat. Daylighting system to be installed on variable-angle elbow to counter roof slope and to ensure daylight tube to remain perpendicular to ground. The complete assembly to be installed on FRP Base of profile which will match roofing sheet. All installation to be done by cutting hole on roof and placing FRP base above this hole. |
