[@williamowen2203]

I've just started watching your channel and I'm impressed. I do have issue with your reason for not chopping out the cavity of the corner of the room beneath that warm roof. I'm not a builder, merely a diy-er but I've built a detached garage, a conservatory and an attached garage extension. You said in the last episode that you know of no builder who does this between the 2 connecting plates of joint and it wasn't right to cut up good house structure for no reason. I did this very modification when building my extension back in the late 90's it was a common thing to do apparently and local building control wanted it done. the reasons were primarily to break the cold bridge between the inner and out leaves of the wall at that point and insert additional insulation. Now, I'm in the middle of this episode and noting your conscientiousness for the thermal break you've created in the parapet wall for the benefit of the warm roof and strength to the external parapet leaf, but I cannot understand why you didn't similarly consider the massive thermal bridge you left in that lower wall by not removing the bridging brick work between the 2 connecting plates of the new wall. Stihl saw would have done the job in 5 mins...

[@Mr_A_Builders]

Hello William. Really appreciate you watching our stuff, thank you. I didn't do it for the reasons that I stated in the video. I've never been told to buy an inspector and never seen anyone do it. I've never ever had an issue and I've built extensions for friends and family, as well as my own at my house, so if there were any issues surely they would have presented themselves by now? Now, I know what you're thinking...you did it and also have never had a problem either...but could that be because what you've done is pointless and has had zero effect? I'm especially sceptical when it comes to houses with solid 9 inch walls...how do I continue a cavity that's not there? Where's that thermal bridge? I'm not saying you're totally wrong and I'm totally right, but there is zero common sense evidence, or just evidence in that case, that either proves me wrong or makes sense that you're right.

[@nigelhaines7900]

Hi Andy we always used lead to go underneath coping stones on a parapet wall to seal it from any rain or damp probs i guess things have moved on but the old ways are the best ive always found

[@brianwood5220]

Really enjoying watching you guys build. Thanks for sharing.

[@Mr_A_Builders]

Nice one, Brian! Take care, mate.

[@markheatrix]

They are easy and brilliant. I did mine 10 years ago, topped the parapet with aluminium capping. Didn't use cavity walls but used 215mm thermalite with 50mm PIR on the outside and then a breathable cladding on the outside. Like a standard pitched roof but vertical with breathable membrane. Went up very fast.

I went about the parapet slightly differently. I had a roof insulation set up designed by Superfoil, not warm or cold, more like a hybrid. My parapet is just the outsode skin, one block above the deck. Theres 90mm pir cavity which comes to the top of the joists, the superfoil quilt is tucked in and stuck down to the cavity creating a consistent seal. Internally theres 100m insulation running right up to the cavity insulation, vapour barrier below it. Apparently meets 0.15 u value.

[@manayconstruction5861]

[@pauldixon3677]

I think there must be different variations of warm roof out there Adam. i finished an extension in February with a warm roof which was EPDM on OSB on Celotex on vapour barrier on OSB. All on top of the silent joists. Roof was about 200mm thick! We also had to clad the outside which we had to counter batten to create an air gap for air flow behind cladding. The roof also had a 2mtr x 1mtr pyramid roof lantern from Eurocell all built same as yours, and yes it had a different size timber to yours, so good info there mate. Great video mate.

[@adamwatson1745]

You mentioned on previous videos that you didn't need a cavity tray over the windows where the roof is constructed directly over the intel, which I agree with. However, do you not see the need for a cavity tray above the steel lintel where you have constructed the parapet wall over the sliding door opening on the rear elevation?

[@Mr_A_Builders]

Hello Adam, hope you're well mate. If it was finished brickwork or render I would have, certainly, but it's going to have a breathable membrane wrapped round it, counterbattoned then a waterproof plastic cladding installed...no water is going through that to warrant wasting the DPC mate!

Talking of hot versus cold roof - I recently converted my conservatory to a flat roof room as I built a WC next to it and just went straight across with the 9x2's - I went for a cold roof with 150mm of celotex covered in 32mm plasterboard/insulation sandwich as per building inspector, and the temperature is pretty stable whatever the weather outside so now a usable space - the hot roof construction seems to entail an awful lot more work but I suppose this is the customers/architects choice and you have to follow it - but I think for me it would be cold roof every time given the choice.

would have been much simpler to just build in the joists with blockwork and add a simple air tightness tray then block above. U value will be exactly the same and would have saved all that messing about with timber above. Alutrix sticks to blockwork. Would have been much quicker and saved a few quid. coping stones need cavity closer under them covering cavity for NHBC now. But as you no longer have a cavity ....

[@Mr_A_Builders]

Can't argue that your way is easier, but it's not as thermally efficient. The whole point of this is to make it as best as it can be, not cut corners for ease.

@@Mr_A_Builders not really, U value will be same if not better. All that metalwork crossing the cav is cold bridging. If anything losing the inside skin is a weak point ?

gonna have to watch this in between periods of the florida/tbay playoff game

[@Mr_A_Builders]

Which one are you rooting for?

[@jayboo8495]

@@Mr_A_Builders neither...screw the both of them. lol. im in an abusive relationship with the toronto maple leafs who are shitting the bed as per usual and if they by some miracle win their series they would be facing florida or tbay. should be a good game though with no real stake in it

[@Mr_A_Builders]

@jayboo8495 haha! "An abusive relationship"!!! That's ace. I feel the exact same way about West Bromwich Albion...which is a few worlds away from where you are!

theres some kind of amalgamating tape could seal where the fixings go through the vapour barrier? or is that too niggly?

[@frog-eye1420]

vapour barrier will self seal to a degree where a screw goes through

Cheers mate.

[@Mr_A_Builders]

It's a good point you make, and frog-eye is right. Although it is a little design flaw, I must say!
