Onduline Roofing Sheet
No other corrugated, plastic roofing material is so easy to handle, so easy to fix and so durable
Onduline roofing sheets are extremely tough, lightweight, corrugated roofing material manufactured from bitumen-saturated organic fibres under intense pressure and heat.
Originally developed over 50 years agao, Onduline is now used extensively in agriculture, light industrial and domestic applications in over 100 countries from the tropics to the Arctic circle.
Onduline is unique in being manufactured from a homogenous base sheet to ensure even penetration of the bitumen asphalt. This produces a sheet of high dimensional stability that cannot delaminate. Colour stability is also ensured through a unique pigmentation process which 'stains' the colour into the sheet. Compare this to the painted finish on lower grade products with the risk of colour fading and surface peeling.
Onduline is easy to work with and safe to handle, it can be cut with a saw and fixed securely with a hammer. Use it as a primary roof covering, on its own or as an oversheet material for renewing old deteriorating roofs. It is also used in the patented Ondutile roof underlay system.
Oversheeting System
Oversheeting with Onduline roofing is often the most economic, practical and safe solution for the renovation of old and deteriorating roofs, particularly where asbestos is concerned. The combination of durability and light weight makes Onduline roofing the ideal oversheeting material and a range of accessories is available to complete the system.
Ondutile Roof Underlay System
Using Onduline roofing sheets, the Onduline system forms an effective secondary weatherproof layer incorporated into the design of tiled and slate roofs. It combines the benefits of roofing underlay, boarding and counter battening in one system providing these benefits :
- Weatherproof secondary under-roof.
- Allows low pitch applications for slates and tiles.
- Increased ventilation.
- Increased sound and thwermail insulation.
- Reduced risk of condensation.
- Ease of application.
- BBA certification.
In line with our policy of continuous development, we reserve the right to change specifications without notice.

KENT's 10 YEAR GUARANTEE
Kent Home Improvements undertakes to supply a replacement free of charge for any PVC sheet that proves to have failed due to a manufacturing defect, in normal weather conditions, during a period of 10 years from the date of purchase.
This guarantee is only valid providing the sheet has been fixed in accordance with the manufacturers' instructions and does not extend to the cost of re-erection or other consequential loss.
This guarantee is offered as an extra benefit and does not affect consumers' statutory rights.

Fixing Instructions
Sheets must not be stacked in direct sunlight or distortion and discolouration will occur, due to the serveral thicknesses acting as a magnifying glass and causing heat build up within the stack. If left in the open, sheets should be covered with an opaque(not black) tarpaulin. Stack height should not exceed 1.22m(4'0") and should be supported on 2" battens, not more than 3' apart.
Cut sheets singly or several together over a firm support. Use a fine tooth saw at a low angle. If 'binding' occurs the saw can be lubricated. Care should be taken in handling and cutting in very cold weather. Extreme caution is recommended at temps below 4.5degrees Centigrade(40 Fahrenheit). Drill sheets singly or several together, preferably over a firm support using a hand or slow speed power drill and a masonry bit. Holes should be 2mm(1/16") oversize the fixing screw or bolt. Never punch holes through the sheets;all holes must be pre-drilled prior to nailing. Always use fixings comprising screws, washers, caps and for better. When lapping ends of sheets the minimum lap should be 150mm (6"). But where the roof slope is less than a 10 degree a 12" overlap is recommended. Never leave inadequately fixed sheets on unfinished jobs. Fixings should not be overtightened and no nearer ends of sheets than 50mm(2"). A false ceiling must not be erected below the sheet as this will cause heat to build up which will discolour or distort trhe sheet.
Wind Loading. Where sheets are to be used on buildings subject to high wind loadings, or other unusual conditions, please refer to the technical advisors.
Flashing. Where sheet meet a wall, the gap should be sealed wiht Clear PVC flashing and flat aluminium flashing or rpeformed aluminium flashing.
Eaves-Fillers. Available to suit all profiles, Insert at eaves and ridge to give a weather-tight seal and a neat finish.
Sealing Tapes. Available to suit all profiles, Insert between lapped sheets to provide a realiable seal against dust and dirt.
It is important to use a crawling board if you cannot avoid working on a roof using plastic roof sheets. This should span the corrugations across at least 2 purlins.
