Give your timber garden building some TLC with ONDULINE CLASSIC
09 June 2026Designing, upgrading or completely refreshing your timber outbuilding doesn’t need to be complicated. With the right materials and a bit of inspiration, even the most tired shed, workshop or garden room can be transformed into a space that’s durable and looks great for years to come.
As well as a stylish roof upgrade, ONDULINE CLASSIC sheets can also be used for external cladding* to create a clean and consistent finish from top to bottom that instantly modernises your building whilst also adding an extra layer of protection against the weather.
One size does fit all
One of the key advantages of ONDULINE CLASSIC sheets is their versatility. Whilst they are a robust and reliable roofing solution, they can also be installed as cladding, allowing you to use the same material across the whole building for a cohesive and considered appearance.
Instead of mixing multiple materials which can sometimes create a mismatched look, using a single solution for both roofing and cladding helps create a smarter and more consistent finish across the entire structure.
Built to last
When refreshing a timber building, performance matters just as much as appearance. Outdoor structures need to withstand everything from heavy rain and strong winds to snow and fluctuating temperatures throughout the year. ONDULINE CLASSIC sheets are weather and UV resistant, helping keep your timber building protected and looking great for years to come. They are also backed by a 15-year warranty when used as roofing sheets for added peace of mind, as well as a 10-year anti-rot guarantee when installed as cladding.
Their corrugated structure helps channel water away efficiently, while the bitumen-based composition provides excellent resistance to moisture and corrosion. Unlike some traditional materials, such as metal or felt, they won’t rust or become brittle over time, making them a dependable long-term solution. They are also four times quieter than metal sheets, reducing noise from rain and storms to create a more relaxed environment.
Made from 50% recycled materials, ONDULINE CLASSIC sheets also offer a more responsible material choice for homeowners looking to refresh their outdoor buildings without compromising on performance.
A quick and simple solution
Refreshing your timber building is more achievable than you might think. ONDULINE CLASSIC sheets are lightweight and easy to install, making them ideal for DIY projects, even for beginners. Better still, no specialist tools are required for installation.
When used on roofs, they can be installed over the top of felt roofing for a fuss-free upgrade. And for cladding they can be fixed directly onto timber frames or existing surfaces, creating a durable and attractive exterior finish.
The benefits go beyond appearance too. Bee from Instagram’s @thecoveychickinn recently used ONDULINE CLASSIC sheets to clad her chicken coop and found they helped create a more comfortable environment for her flock during warmer weather.
The chicken coop cladding has given the girls an enclosed, yet airy, shaded space and their run is actually now slightly cooler than outside which is ideal in the recent heatwaves. It’s not hot to touch like most felt materials either. We’re very pleased with it.
