MAXWELL Posted July 4, 2020 Share Posted July 4, 2020 Are most brands of the plain P5 chipboard flooring the same quality or are some better than others also are the flooring sheets with the protective coatings worth the extra money as they cost considerably more per sheet Link to comment Share on other sites More sharing options...

Russell griffiths Posted July 4, 2020 Share Posted July 4, 2020 You only need the one with the protection layer if you are leaving it with no roof above it for some time. Link to comment Share on other sites More sharing options...

Mr Punter Posted July 4, 2020 Share Posted July 4, 2020 I prefer Egger Protect to Caber Link to comment Share on other sites More sharing options...
Onoff Posted July 4, 2020 Share Posted July 4, 2020 Is Caber or Egger ever used on a "flat" roof? Guessing not as fibreglass or EPDM might not stick to it? Link to comment Share on other sites More sharing options...

Screws hold better, edges hold up better etc. (I'll probably get some stick for that). Link to comment Share on other sites More sharing options...

Onoff Posted July 5, 2020 Share Posted July 5, 2020 (edited) Slightly off topic but I refoofed a Wendy house with 18mm OSB3 then painted it with No Nonsense wood treatment. I never got around to felting the roof, just slung a tarp on weighted down with some roof tiles. It's been like that for about 3 years now. The edges of the OSB3 have "grown" as in they've thickened from 18mm. Would the wood treatment maybe break down the glues used to hold the OSB3 together? I see OSB3 used all the time on here I know. I don't think I've ever seen anyone paint it with anything. Edited July 5, 2020 by Onoff Link to comment Share on other sites More sharing options...

There is no benefit in using marine ply as the only guarantee is the voids within the plies and there is zero stress on a flat roof unlike a boat hull.

Like the super expensive stuff I bought when I did the bathroom / bath deck and surrounds. No voids and just excellent imo. Is ply not better in bending than OSB3 of the same thickness?
