Transparent polycarbonate skylight profile sheets are an effective way to allow natural light into aluminium roofs. Embossed sheets offer controlled light transmission, contributing to energy efficiency. Using these sheets minimizes the need for artificial lighting during daylight hours, leading to significant savings on energy costs.
Transparent polycarbonate profile sheets are available in a standard thickness of 2 mm with embossing.
These sheets are engineered to block heat while permitting light wavelengths to penetrate, making them an excellent energy-efficient solution. Multiwall sheets, particularly in 6 mm and 8 mm thicknesses, are ideal for applications such as wiregrass in north light sheds.
The Skylight SunInside is a tubular daylighting system developed through technical collaboration with 3M India Ltd. This system integrates natural light into indoor spaces through an innovative four-component design:
A UV-resistant, clear polycarbonate dome with a flange captures sunlight.
| Parameter | Specifications |
| Transmission | Minimum 80% |
| Refractive Index | 1.58 |
| Service Temperature | -10ºC to 80ºC |
| Thickness | 2mm at flange |
This component consists of an aluminium sheet coated with a high-reflectivity mirror film.
A lens diffuser crafted from UV-stabilized polycarbonate film ensures uniform light dispersion.

| Diffuser type | Lens |
The mounting system ensures an airtight setup to prevent dust infiltration and maintain reflectivity. It also insulates the tube from heat transfer.
Installation involves mounting the system at a variable-angle elbow to match the roof's slope, ensuring the daylight tube remains parallel to the ground. The assembly is placed on an FRP base profile matching the roof sheet, with a hole of up to 675 mm in diameter cut into the roof for installation.
A UV-resistant, clear polycarbonate dome with a flange captures sunlight.
| Component | Specifications |
| Diameter (4 ft long duct) | 500 mm |
| Typical Coverage Area | 750 sq. ft - 1200 sq. ft, depending on Lux requirement and height of installation |
This innovative daylighting system channels sunlight indoors, illuminating spaces that traditional windows or skylights cannot reach.
Key Benefits of Skylight Integration Over FRP or Polycarbonate Sheets:
1. Enhanced safety for workers on the roof.
2. Prevention of water leakage during installation.
