Polycarbonate embossed translucent sheets:
It is preferable to use transparent polycarbonate skylight profile sheet. This is the simplest method of getting natural light through a steel sheet roof, controlled light transmission is achieved by embossed translucent sheets. It is required to save energy wherever possible. Artificial light are not used in day time resulting in huge saving in energy bills.
Transparent polycarbonate profile sheet is available in 2mm emboss thickness.
Multiwall polycarbonate sheets :
Selectively prevent heat penetration allowing the visible wavelength to penetrate the sheets. This makes Multiwall sheets the ideal energy saving solution.
Multiwall polycarbonate sheets are good option in 6mm and 8mm for wireglass used in north light shed.
- Superior shading capability – more effective heat reflection than competative sheet.
- Attractive finish.
- Environment friendly material.
- Available in 6mm, 8mm, 10mm and other thickness.
Sun inside are design to provide nature light into the shade where ever required. There are a new way to get natural light into factory / office building they can transform space that sunlight would not normaly reach
Tubular guided daylighting system has been made in technical partnership with 3M India Ltd.
The daylight guidance system broadly consists of four different parts:
1. Collection System
Clear, UV resistant polycarbonate dome with flange
-10ºC to 80ºC
2mm at flange
2. Guidance System
Aluminium covered with mirror film
Aluminium Sheet Thickness: 0.4mm
The mirror film surface should have a luminous reflectivity of 99% 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.
Lens Diffuser made from UV stabilized polycarbonate film
2. Roof Mounting System
Leak proof installation of the system on customer roof
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 of maximum 675 mm diameter on roof and placing FRP base above this hole.
Diameter (4 ft long duct)
Typical Coverage Area
750 sq ft – 1200 sq ft, depending on Lux requirement and height of installation
magine 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:
- Safety of people working on the roof
- Water leakage through installation
