PVC Roofing Sheets

In comparison to traditional metal base roofing systems, Lotus PVC Roofings have superior and effective thermal and noise insulation properties. Hence, there is no need to opt for additional heat and noise insulation material during construction.

Lotus PVC sheets can be recycled. They do not contain asbestos or any harmful chemicals. They are resistant to fungal growth and termites. Hence they are the perfect choice for industries that require high levels of hygiene - like food processing, pharmaceuticals, food courts, hawker centers and schools.

This product can be bent into arch shapes to comply with various architectural requirements.

Due to its inherent characteristics, U–PVC- Polyvinyl Chloride - the product withstands salty air from the seas and other forms of chemical corrosion that normally cause rusting on metal roofings. Moreover, adopting advanced Polymer Processing Technology has enabled the product to withstand harsh weather conditions and prolonged sun exposure, without affecting its physical properties.

Strong and Lightweight Easy to Install Water Resistance Cost-Effective

**Handling and Storage** - The sheets should never be transported atop the roof of buses, vans etc. - Flat sturdy pallets must be used to transport and store the sheets horizontally. The size of the pallets must be larger than the sheets **Purlins** - The recommended maximum distance between the purlins is 600 mm only. - When designing a new roof it is recommended that the slope be above 15% (9°) **Adhesives and Sealants** - Solvent mixtures and cyanoakrylate adhesives compatible with PVC can be used for bonding. Silicon Sealants can also be used to prevent entry of water, wind, insects, etc. between installed sheets. **Roof Fastening** - A roof fastening screw should be inserted into atleast every third corrugation top at each internal purlin - Along the edge purlin the screws are to be inserted into alternate corrugation valley - Sheet to sheet fasteners should be used to create a seal between overlapping sheets between purlins - Self-tapping screws with pre-drilled holes or self-drilling screws can also be used - Improper insertion and negligence in the use of fasteners can damage the sheet and result in leaks. Special attention should be given in this regard. - The Sheets should be laid against the direction of wind and rain in order to prevent the roof from getting blown off
