Pocster Posted December 10, 2023 Share Posted December 10, 2023 Not an issue yet . Roof light well is tile backer board with foil backed ceiling tile stuck to it . Ceiling had to be fire resistant tiles ( just a fibre glass backing ) Whilst not a major issue yet can only assume will get worse . I could get this tile out - but then what ? . Try and ‘line’ in the Lightwell backside ? . Cover back of replacement tile in foil ??? Link to comment Share on other sites More sharing options...
Mr Punter Posted December 10, 2023 Share Posted December 10, 2023 Suspended ceiling tiles get water stains really easily. Is there any way you could help prevent the condensation forming in the first place? Celotex? 1 Link to comment Share on other sites More sharing options...

Can just about get my hands in there … Link to comment Share on other sites More sharing options...
joe90 Posted December 10, 2023 Share Posted December 10, 2023 Well insulation should stop the warm air hitting the cold surround that causes the condensation. 🤷♂️ 1 Link to comment Share on other sites More sharing options...

Pocster Posted December 10, 2023 Author Share Posted December 10, 2023 Of course I have no celotex so late in my build . All those off cuts skipped - typically 🫤 Will let it get worse first 🤣 Link to comment Share on other sites More sharing options...

Redbeard Posted December 11, 2023 Share Posted December 11, 2023 Look for local loft conversions in progress and scrutinise the skips. 2 Link to comment Share on other sites More sharing options...

Mr Punter Posted December 11, 2023 Share Posted December 11, 2023 You may only need a couple of sheets of 25mm. Cheapish. Link to comment Share on other sites More sharing options...

I’m only going to initially do that one side . I can’t do up to the glass as that is in the roof / floor . So just in the ceiling void . Maybe 30 cm by 60cm - something like that . Probably though buy 1 whole 25mm sheet Link to comment Share on other sites More sharing options...
