Polycarbonate Skylight Sheets

This is the most efficient method to control light transmission through the steel sheet roof.
Available in all required profiles.

Polycarbonate embossed translucent sheets:

Profile features:

It is best to choose transparent polycarbonate skylight profile sheets. This is the simplest way to let natural light into an aluminium sheet roof. controlled light transmission can be achieved through embossed transparent sheets. It is required to save energy wherever possible. Artificial light is not used in day time resulting in huge saving in energy bills.

Transparent profile sheets of polycarbonate are available in a thickness of 2mm emboss.

Multiwall polycarbonate sheets:

The sheet is designed to prevent heat from entering the sheets, allowing light wavelengths to pass through into the sheets. This makes Multiwall sheets the ideal energy saving solution.

Multiwall polycarbonate sheets are a great choice in 8mm and 6mm for wiregrass in north light sheds.

Advantage:

Superior shading capability – more effective heat reflection than competitive sheet.
Attractive finish.
Environment friendly material.
Available in 6mm, 8mm, 10mm and other thickness.

Skylight SunInside

The tubular-guided daylighting system has been developed in technical collaboration in collaboration with 3M India Ltd. The daylight guidance system broadly consists of four different parts:

1. Collection System:

Clear, UV resistant polycarbonate dome with flange

Parameter	Specifications
Transmission	Minimum 80%
Refractive Index	1.58
Service Temperature	-10ºC to 80ºC
Thickness	2mm at flange

2. Guidance System:

Aluminum covered with mirror film

Specifications

Aluminum 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.

3. Diffuser

Lens Diffuser made from UV stabilized polycarbonate film

Parameter	Specifications
Diffuser type	Lens

4. Roof Mounting System

Specifications

The system is installed in such a way that the light guidance component of the system is airtight. This is important to stop dust from getting into the tube, ensuring that the reflectivity remains. Also, it is important to ensure it is that the air column within the tube functions as an insulator to heat.

Daylighting system that is to be installed on a variable-angle elbow in order to counter slope of roof and ensure that daylight tube is parallel to the ground. The whole assembly is to be placed on a FRP base profile that will match the roofing sheet. All installation to be done by cutting hole of maximum 675 mm diameter on roof and placing FRP base above this hole.

Technical Specifications

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

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) that can illuminate the areas of your buildings by natural sunlight that is efficient in energy use.

Skylight integration on the roof has advantages over FRP or polycarbonate daylighting/ skylight sheets based on the following aspects:

Safety of people working on the roof
Water leakage through installation

Process:

Collect

A dome-shaped structure that has a special optical system that takes sunlight from all directions, then redirects it down into the tube below. The collector makes sure that the brightness of the sunlight absorbed remains the same throughout the morning, during noon and later in the evening.

Transmit

3MTM Specular Film provides high reflectivity, minimal loss and no colour shift (even in cloudy conditions). It has the highest visible reflectivity (photopic reflectivity >99%).

Diffuse

3MTM Diffuser Film allows uniform light distribution and can be controlled in indoor spaces. Its unique design helps reduce the glare and eliminates hot spots as well as, due to the plastic that is optical-grade it doesn't alter the colours of the light that is transmitted.
