Dripstop Information

At Cladco Profiles, we do whatever we can to ensure every item you buy works for you for as long as possible. Roof sweating can occur with metal roofing, and Dripstop is a tried and tested way of preventing it.

‘Roof sweating’ occurs in uninsulated buildings when excess humidity condenses on the reverse of your roof. It usually happens around the beginning and the end of the day because of the stark difference in temperature inside and outside your roof. Water vapour collects until it forms into droplets which start to fall. This could cause rot, or rust, as well as damage to your floor if the drips are substantial.

Dripstop can be added to 32/1000 Box Profile, 34/1000 Box Profile, 13/3 Corrugated and 41/1000 Tile Form Sheets. It is recommended, to help the Dripstop work, that the roof pitch should be more than 10 degrees. Please get in touch with our sales team on 01837 659901 to enquire about using Dripstop in your project.


What is Dripstop?

Dripstop is an anti-condensation, grey polyester fleece membrane which is applied to the reverse of sheet profiles to prevent any dripping in conditions of high humidity. The clever technology traps moisture in specially-designed pockets which are formed within the membrane. Those pockets hold any liquid until it can be released back into the environment within your building as normal humidity. It’s important to not expose the Dripstop side of the roof to sunlight, strong wind or rain to prevent damage. For more information on Dripstop, read our blog.

How does Dripstop work?

Dripstop prevents water droplets from occurring by collecting vapour in small pockets that sit within the membrane, essentially soaking it up like a towel. As the air around it warms up again, the collected water evaporates into the air and the fleece membrane dries out. Does Dripstop work to stop condensation? While it does wonders for trapping condensation, Dripstop cannot stop it from happening. For the material to work properly, your building must have adequate ventilation to allow the membrane to dry out as part of its cycle for it to work to its full potential.

Dripstop is resistant to ageing and provides an extra protective layer to your roof – it’s a cost-effective measure that maintains the structural integrity and aesthetics of your roof, therefore requiring less conservation than more traditional methods. Dripstop is easy to clean using a hose or pressure washer and is incredibly durable, resisting environmental temperatures from -40C to +80C, so there really are no downsides!
