Onduline lightweight roofing systems are used worldwide for many industrial, agricultural and DIY applications.


  • ONDULINE® CLASSIC Sheet: Made from 50% recycled cellulose fibres. The CLASSIC sheet is an extremely tough and flexible lightweight corrugated sheet with a 15-year guarantee. The material used to make ONDULINE® sheets is 4 times quieter than metal sheeting, making them a popular choice for DIY applications and agricultural projects, especially stables housing horses.


  • ISOLINE® LOW LINE: Unique sub-roof system and the only system in the UK to be BRE tested and BBA Accredited to as low as 10o with a 30-year guarantee. This lightweight bituminous underlay sheeting is fixed below the primary tile or slate roof covering, creating a waterproof secondary roof. Ideal for use under concrete, slate or clay tiles for very low-pitched roofs, this solution offers a perfect waterproof barrier against potential water ingress that may happen over time through a breach in the primary roof covering. It also enables the primary tiled or slate roof to be used safely, below the manufacturer’s minimum recommended roof pitch. 


  • ONDUVILLA® Tile Strip: An attractive and innovative tile designed with a 3-tone colour finish and grooved lap joints to improve weathering performance on all types of timber structures from garden buildings to stables and commercial offices.


  • BARDOLINE® roof shingles: Asphalt shingle tile strips to create an attractive traditional roof finish. AA fire rated making it suitable for all roofing projects.


  • ONDUTISS® membranes: Quality roofing underlay membranes and facade wraps to protect and insulate all types of buildings, from residential to commercial. Complete waterproofing and protection.
