FRP Skylight Roofing Profile Sheets
Roofclad has been manufacturing superior grade Fiberglass and Polycarbonate roofing and Cladding products, translucent, clear and opaque finish for all kinds of Industrial Warehouse, Residential, Commercial buildings and open sheds. A naturally well lit building of any kind that is bright and with full of soothing light seems more in touch with Mothers Nature, when you allow all the natural Sunshine goodness inside the building. Natural light is very important in creating condusive environment for educational, residential & industries, always resulting in better achievements and higher productivity. In short, it is an undisputed fact, that people are happier and productive in buildings that are naturally lit. Moreover, with the recent focus on sustainability and reduction of every day consumption and CO2 emission, the benefits of roof lighting have become compelling and forms very important part of any building in terms of utility, application, architectural and aesthetic looks along with sustainability and durability of the Skylight Product being used. Hence, the selection of rooflight product becomes very important and sometimes an architectural choice, but is usually more influenced by the roof system in terms of geographical location, application, durability, looks and environment.
Types of different Durable Rooflight Products:
1. FRP Roofing Products- Available in Clear & Color Translucent Sheets and opaque Sheets in plain & embossed finish.
2. Polycarbonate Roofings products – Clear & Color Translucent Sheets in plain & embossed finish.
FRP Roofing System
FRP Skylight Sheets is a wonder composite material consisting of Fiberglass reinforcement in a matrix of UV Stabilized unsaturated polyester sheet grade resin system forming a tough laminate in desired profile having exceptional strength to weight ratio. FRP offers almost unlimited possibilities for shape, size, profile and color and known for its high strength, durability, water/chemical proof, dimensional stability, high resistance to environmental corrosion due to extremes of temperature
and weather including emission of natural and Industrial Chemical fumes. FRP Sheets are light in weight, good aesthetic appeal, easy to install and maintain. We at Roofclad are manufacturing FRP Sheets using State-of-the-Art sandwitched molding process resulting in excellent smooth glossy surface finish.

FRP Chemical Resistant Sheets
Technical Note on FRP Chemical Resistant Sheets for Industrial Building Roofing or Cladding
Industrial Roofing and Cladding are exposed to extremes of weathering conditions, water, chemical fumes or chemical environment and constant exposure to humid conditions. Under these conditions Roofing & Cladding are prone to corrosion and selection of Roofing material should be done accordingly.
Normally, Color Coated Profile Metal Sheets in 0.5 mm thickness are used for roofing in combination with FRP Skylights, FRP Gutter, Turbo Ventilator and Accessories under normal weathering and environmental conditions. In general, Mild Steel are highly corrosive material even under normal environmental conditions but the same is color coated with few microns of weather resistant paints which has very limited self life. But in presence of harsh weathering, chemical fumes or coastal environments, the M.S. Color Coated Profile Sheets are under constant threat of corrosion and not recommended for Roofing taking into consideration of minimum 10 years self life.
FRP Skylight / Chemical Resistant Sheets is a Fiber Glass Reinforced u/v stabilized unsaturated Polyester resin system composite material consisting of a network of reinforcing glass fibers embedded in a matrix of thermosetting resin. FRP offers almost unlimited possibilities for shape, profile, size and color, which is known for its high resistance to wreathing & environmental corrosion, chemicals, fumes with inherent property of high strength, durability, water, chemical proof, light weight, dimensional stability, aesthetic appeal and easy to install and maintain.
At Roofclad we are India’s First Manufacturer to have developed special process for manufacturing of FRP Chemical Resistant Sheets, in which two step special coating is done to provide maximum resistance against most of the harsh chemicals at elevated temperatures and retaining the mechanical properties of the sheet. The said sheets are custom made in any required profile and in transportable length. Due to two step protection against corrossion the sheet has enhanced life of more than 15 - 20 years and are best suited and recommended roofing sheets under these circumstances and to replace the conventional roofing system which used to weather out and corrode very fast and required heavy maintentance periodically.
Life cycle costs of FRP Chemical Sheets are very economical as compared to other conventional roofing material due to above said properties of the sheets.
Properties & Advantages
a. Excellent corrosion resistant from all kind of alkali, acid, chemical fumes, coastal environment, water and extremes of weather & temperature.

e. Electrical Characteristics – FRP Sheet has high di-electric constants.
f. Considerable Design Versatility – Can be molded to match your profile in any transportable length.
g. The said FRP Chemical Resistant sheets are available in Translucent & Opaque colors.
