Homer Posted May 9, 2021 Share Posted May 9, 2021 Hello we have moved to a house close to the North Cornwall coast and have been advised against using aluminium due to corrosion. We have also been told that 'Cedral' cladding is a good idea, but I am surprised because all the profiles are aluminium...Surely that won't last, even if the actual cladding boards do? Does anyone have experience with this please? I am wondering if all the 'cedral' cladded houses we have seen (all look pretty new) will suffer due to the corrosion of the aluminium parts. Cheers, Homer Link to comment Share on other sites More sharing options...
nod Posted May 9, 2021 Share Posted May 9, 2021 Some of the composite cladding looks good and also the cement board cladding Both are unaffected by severe weather I did one last year in Cedar I don’t think I would use it on my own home For the reasons you have highlighted Link to comment Share on other sites More sharing options...

Aluminium generally, does not corrode, but if the wrong fittings are used there can be an electrolysis problem. Also, how close to the coast, and how high up. The big waves come in from the SW. 1 Link to comment Share on other sites More sharing options...
Homer Posted May 9, 2021 Author Share Posted May 9, 2021 (edited) Yes, the fibrous cement product part is fine, but all the profiles that you have to use to put it up are made of aluminium. We are less than a mile from the sea in an exposed position on the North Cornwall coast - surfers heaven - Aluminium fittings- door handle etc- on the uPVC sliding doors already pitted, clearly affected by the salty air and the window fitters have all advised against getting aluminium as it needs regular washing down to keep it looking good.

nod Posted May 9, 2021 Share Posted May 9, 2021 One of our jobs has a engineered wood cladding that is fixed with a stainless steel clip system It comes with a 25 year guarantee But at £50 per length Isn’t cheap Link to comment Share on other sites More sharing options...

Do you know the name of the product please? Edited May 9, 2021 by Homer Link to comment Share on other sites More sharing options...

These are often factory finished with paint apart from the ones that are concealed. Link to comment Share on other sites More sharing options...

Do you know if aluminium corrosion is more than surface deep - ie will it weaken it? If it is just unsightly but doesn't affect the strength (and will last as long as the fibre concrete boards do) then that is fine. Thank you for your advice BTW.

Marvin Posted May 9, 2021 Share Posted May 9, 2021 If your going for Aluminium it seems that power coating Aluminium is the best way forward and as SteamyTea says avoid electrolysis (which does not mean torturing you sister) Link to comment Share on other sites More sharing options...

Have a look at the fine print. We will have powder coated aluminium gutters and the manufacturer - very reputable, won't offer more than 10 years corrosion guarentee cos we are within 1km of sea. Normal would be 30 years IIRC. 2 Link to comment Share on other sites More sharing options...

I am sure with a bit of hunting about the correct fixings can be found. Or just use nylon battens. Link to comment Share on other sites More sharing options...
