No other roofing material is so easy to handle, so easy to fix and so durable

Onduline is 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 and safe to handle, it can be cut with a saw and fixed 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 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 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.
Immediate roof protection.
BBA certification.

Onduline is available in black, green, red and brown. Slate grey is available, subject to a minimum order quantity of 300 sheets.

A complete range of Onduline components and accessories is available to ensure easy and professional fixing and to provide for every eventuality in roof design.

A series of leaflets is available, providing detailed information and fixing instructions for Onduline roofing systems as follows:
