We Provide

Sheets and Onduvilla Tiles

General Characteristics

Onduline sheets are manufactured by impregnating organic cellulose fibres with bitumen under high temperature and pressure. The sheets are pre pigmented with special purpose resins. The impregnation of colour into the sheets is done using patented techniques that enable the sheets to retain their colour over a longer period of time even under harsh conditions. The patented manufacturing process ensures uniform bitumen penetration into the sheets providing an excellent dimensional stability to the product and thereby preventing delamination.

Onduline sheets offer the following benefits:
Excellent waterproofing characteristics,Can be used in extreme climatic conditions High insulation and sound absorbency values,Resistant to corrosion-does not rust, rot or become brittle Light weight- 6.4kg per sheet of 1.9m2 area, Can withstand wind speeds up to 192km/hr.
Does not break during transportation and installation,Available in a range of environmentally sensitive colours, Excellent colour retention, Requires minimum maintenance. Contains no hazardous chemicals

Installation guidelines
Onduline is a flexible material that can be easily installed on various surfaces including Steel Truss work, wooden structures and on concrete. Onduline sheets can be cut as required and can be used on round roofs as well.
The minimum recommended slope for fixing the sheets directly on the roof is 10 degrees. In case the slope is lower than this value, we recommend a full decking on the roof

For frames with slope below 10degree slope, the end overlap should be 30cm and the side overlap should be 2 corrugations.
