Imagine an innovative system that harnesses sunlight and guides it indoors in a way that would be impossible with windows or skylights. Tubular Daylight System (TDS) which light up interiors of your buildings with natural sunlight which is energy efficient.
Integration of SunInside on the roof scores over FRP or polycarbonate daylighting / skylight sheets on the following points:
A dome shaped structure with specialized optical system that efficiently captures sunlight from multiple directions, collects and redirects it downward into the duct below. The collector ensures that the intensity of sunlight captured remains similar during morning, at noon and in the evening.
High Reflective Sheet provides minimum light loss and no colour shift (even in cloudy conditions). It has the highest visible reflectivity (photopic reflectivity >98%).
3MTM Diffuser Film enables uniform light spread and control in interior spaces. The unique lens design reduces glare and eliminates hot spots, and because of the optical-grade plastic used, the film does not alter the colours of the transmitted light.
SunInside500 Tubular guided daylighting system has been made in technical partnership with 3M India Ltd.
The daylight guidance system broadly consist of four different parts:
|Service Temperature||-10°C to 80°C|
|Thickness||2mm at flange|
|Aluminium Sheet Thickness: 0.4mm - 0.5mm|
|The film surface should have a luminous reflectivity of 98% and a bandwidth reflectivity of over 90% for 400 to 775nm wavelength of light incident between 0 to 80 degrees.|
|The mirrored surface shall be protected by a plastic sheet until final installation of the system.|
The system is installed in such a way that the light guidance component of the system is airtight. 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.
