Hi everyone Could anyone help please! I just replaced old ceilings in bedrooms with 9.5mm boards. Are they thick enough to last? Do I need to cross board with another layer of 9.5mm? Or should I have used 12.5mm? Early reply would be appreciated. Thanks

Good afternoon Noseall! Thanks. Anything else, like plastic sheet etc? Do I just dump soil on top of bricks???

Good morning! Would anyone be able to advise on construction of domestic rainwater soakaway. I am aware it needs to be a min 5m from the main dwelling, approximately 2mcubic below outlet. I calculated 1mcubic per every 16sqm of roof, as per BC regs. Not sure of the layers needed...

Thanks Dulux. Just in time as well!!!! Will let you know how we got on. Have a good day

Thanks Dulux Your reply came just in time. We have prepared everything for tomorrow morning. I fixed battens horizontally and flush between the rafters every 1500mm to be able to staple edge of the foil to them. Wasn't aware that I have to do it. Actis own website and Triso UK website have...

Hi Everyone! So I am ready for my Tri Iso 10 to go on the roof tomorrow morning. There needs to be 25mm gap between multifoil and breather membrane. Membrane needs to sag a bit between rafters. I am using 38x25 battens. If it sags there will be less than 25mm gap! What do I do? BC...

Hi Robert too! My BC Richmond-upon-Thames just agreed for me to install Tri Iso Super 10! Apparently on November 11th court ruled in favour of ACTIS. So called Hot Box test BR443 was decided as not relevant to this particular product and it is now cetain Tri Iso will be recognised under Part...

Good news! Building Inspector passed our roof today! Feels great. Will be having our celebratory drinks tomorrow night. Eager to put some pictures on but still not sure how to do it! BI sympathetic to Tri Iso Super 10 but needs to check with his superiors. Will be much easier if he...

Wow Chri5!!!!!!!!!!! I am not too sure what is your problem. How I do I discredit "you folks" and my boys? I have been told by "your folks" to sack my Polish builders as they know nothing. On this assumption the whole credit has to go to me! They are doing a fantastic job but they...

Thanks Noseall Tri Iso Super 10 has a valid TRADA certificate. I cannot understand why some Local Authorities love it while others hate it. It is permissable in Scotland and all over continental Europe. Isn't it because it is made in France??????

Good evening all Could anyone tell me whether Tri Iso Super 10 is permissable under part L of building regulations??? Thanks

Thanks AtoZ. I have already resolved the question of roof support. My existing steel is sufficient for supporting wall and so the roof is now coming along nicely!!! Literally as I write this. Question about roof covering. I am taking off existing hand made clay tiles. Some of them are...

Thanks to Noseall and Pantsmachine! I have reached an impasse!!!!!!!!!!!!! My plans suggest truss roof. I am doing cut roof supported on walls which already have a lot of steel beams/columns. There is obviously additional load from cut roof. I therefore need to build a supporting wall to...

Thanks Noseall! Of course we will restrain it before doing anything else! Shall I also nail it to blockwork? So far extended old roof and now coming to hip area... Old hip blades are massive: 2.5 inch by 9inch. Do we really need them as big as this? How do I connect old/new purlin...

Good morning all! Roof level wall plate: does it have to be bedded onto mortar with DPC underneath timber? Do I need DPC there at all? Early reply would be appreciated. Need to have it in place today so it is ready to received roof timbers on Monday. Thanks :lol:

This was for PANTSMACHINE but I made a mess of it!

Sorry, forgot to add pitch of the roof; it stands at 40 degrees

Thanks again Noseall. Span of new roof is approximate 10m x 5.20m. Purlins are supported by posts sitting on double joists. If 6x3 is too flimsy should I change it or just continue with 8/9x3 in new part? Rafters seem to be in a very good condition considering the house dates back to...

Thank God for Noseall!!! My architect specified trussed roof. I decided to go for cut version because we have another small hip roof joined to it and it all seemed too complicated. Original purlins are odd size: 150mm x 80mm so I will probably go for 6x3 if I can find such size! I...
