You guys are awesome ,you don't cut corners, I've worked with many builders and they all cut corners and don't do as good a job as you guys ,bravo
Fantastic as always. You guys are QUALITY and it’s nice to see some good English builders like you instead of these Eastern European cowboys you get down in London. Once again smashing music, you guys have got good taste. Roll on next Sunday 🙂👍
You are experienced enough to know you are doing it the best possible way. All I see on TH-cam is people second-guessing themselves or worrying what the TH-cam haters will say, I can't wait to see what it'll look like when finished
Thank you, Garry. Really appreciate your comment and your time. Hope you're well, take care.
@mrabuilders6723 My pleasure, My Uncle was a builder from Stourbridge so I feel I have to stick up for the brummies
So nice to continually watch builders who know exactly what they're talking about and be able to explain it properly! I spend my life trying to explain to customers why we work the way we do, an you boys do it perfectly for us viewer's ❤
Ah thank you, Polly. Really appreciate that and glad you can decipher our gibberish! Hope you're well, take care.
You have insulated that parapet wall as per Joseph Lstiburek of the building science corporation details in Canada and the USA. If anyone has time it's well worth looking him up and all the video guides for warm roofs and wall structures.
That's great mate, will do. Appreciate that. Take care mate.
Love your videos and you make everything look so easy. Look forward to the next one
Cheers, Stephen. Hope you're well mate.
Coming along great lads. Superb viewing from my front row seat, feet up, coffee in one hand , ciggie in the other.😉Go on Richard, swear 🤬do. I’m swearing every day for one thing or the other as I’m renovating my property. 😂
Haha! Turning the air blue every now and again is good for the soul! Good luck with your project, mate.
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.
Another job smashed out, and again it's great to see honest builders doing thing the best way, and try to make it better on the pocket when you can. Not by the usual jack of all trades way by cutting corners, but by good old sourcing of good materials but at better prices. Loving it
Nice one, Mark! Really appreciate that, mate. It would be great if there was a one stop shop out there but we all know that there isn't! Thanks again mate, hope you're well.
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
Well what an incredible film it's supper to watch you lads . 👍
Thank you, David. Appreciate that mate.
Really enjoying watching you guys build. Thanks for sharing.
Nice one, Brian! Take care, mate.
Another great Sunday night 41 minute video. Perfectionist isn’t in it!
Can hear the frustration that you didn’t get finished. But looking on the bright side, we get a part 2!!!
Cheers Don! Appreciate that mate, take care.
Why not cap the parapet with OSB/ply to give smooth top surface to receive GRP, oversize width on cladded elevation then cut back to suit once wall build up established, then install edge trim with neat GRP weathered junction strip. - Really enjoying this build series, great job lads👍
Quite unbelievably, Mike, that's exactly what will be happening!
Perfect tea time viewing! (Breakfast, dinner and tea in my house 😃) Well explained video Adam and Rich, if you feel that it needs to be insulated above the wall plate go for it, it can do no harm at all. We’ve all had the “expected” delivery dates, usually not the fault of the supplier. As always looking forward to next week. Have a good one. 😊
Hello Simon, apologies for the late reply! Hope you're well mate. Thank you for taking the time to watch our stuff yet again! Hope you're having a great week.
Its coming together nicely. Loads of thought and attention to detail. Thanks for sharing.
Thank you, Pete. Hope you're well mate.
Great video... When I built my extension I put a piece of masking tape over each screw fixing so that when it's glassed over the screws are still accessible and not gummed up with resin.. Keep up the good work. Looking forward to the glass fibre going on ...
That's a top tip mate! I like that!
Great explanation on the furring strips Richard + trigonometry 👍
Cheers Tony, hope you're well mate.
All good mate thank you 👍
You are good builders👏👏👏👏. Really enjoy your videos and I am learning so much from you👍👍👍
Thank you, Peter.
Another great explanatory episode guys. Nice to see Rich standing and looking so serious when you foul stuff up. I bet he has a bloody good giggle in the car later...
Haha! There's many a giggle at my expense! Cheers matey, hope you're well.
Haha 😆 “that ice cream vans going a bit fast” 👍
Nice work again lads.
I’ve said it before and I’ll say it again. I do like these Sunday evening videos.
Haha! Keep saying it mate! Cheers man, all the best.
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.
Thanks for the explanation re the firrings and diminishing batons - I suspected it was to make good use of available materials. Great video as usual
Our pleasure Sarah. Thank you for getting involved. Hope you're well, take care.
Great job guys.
Thank you, Rich. Take care, mate.
Nice work boys 👍 I'll be interested in how you box those pipes in to be watertight 😁
Set a parapet umbrella that will do. Other wise the soil pipe will have to move elsewhere.
You and me both!!! Haha!!!
@@mrabuilders6723 😳😂
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.
Yes mate, there's definitely different ways of doing things, although your roof is the same as ours, just the covering is different. Cheers Paul, hope you're well, mate.
Another great video
Thank you, Robert. Really appreciate that. Hope you're well, mate.
Great video
Thank you, Phil. All the best, mate.
Ive just build a roof very similar but with three sky lights, feel your pain with working out the upstands, these ones needed a rebate because they are triple glazed
They are a nightmare aren't they! No two are the same!
35:18....there is always someone lying down on the job😉. Great video explaining the thermal roof construction🙏🙏👍👍💪💪.
good stuff!
Cheers mate.
Very interesting to learn how you do all this thanks chaps. A penchant for the blues i note via your timelapses.🎵
We've tried all sorts of music and this seems to be the best cried pleaser! Which suits me!
Great solutions there, thanks for the video,Tra Rabit! 🐇
Haha! Cheers mate!
Looking great lads.
Nice one, Ross.
If you had built the wall up another 4 blocks it could of been a swimming pool on the roof, and no need for a drain
Haha! Let's see if it will withstand a light rain first!
I am totally with you in your explanation of your thermal integrations. I just hope your building inspector has the capacity to understand what you are doing. My experience tells me that it takes a lot to get anything ingenious understood. Your videos should help.
Thank you, Charlie. Our building inspectors are pretty switched on so fingers crossed!
Don't even begin to think that they know what they are talking about.
Couple of muppets talking claptrap. The owner should be very worried. Where is the bloody drawing? Who do they think they are , making it up as they go along.
They got booted off their last job because they decided they knew better than the architect and structural engineer. IDIOTS.
Rich doing his best statue impression again. No offence rich👍👍.
Yep that’s all I do. I stand as still as possible so Adam can film and then go sit back in the van. 👍🏻
Great work and explanation
Thank you, Simon. Hope you're well mate.
I wondered about them pipes!
love these videos pal always gives me ideas for my channel
Lets say I won the lottery and wanted someone to design and build me a house from scratch would you guys be interested? You could film anything you want.
Haha! Yes! Very interested!
nice job on the roof ... if the clients want a bit of bling on the parapit wall top it could be dressed in lead .... expensive but cant be beat ....
I'm pretty sure that lead can be beat...that's a joke for all you lead workers out there! Haha! You're right mate but that fit in with the design, which is something that I'll cover in the next episode. Cheers, mate. Hope you're well.
@@mrabuilders6723 im good thanks walked into that didnt i lol ... looking forward to your next video ... take care wishing you and the lads a productive enjoyable week ....
i prefer EPDM to lead because lead has to have expansion gaps, which get filled with water, then ice opens them, then leaves get in, more ice, leaks....
cheers pal
No worries, man.
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?
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! Cheers mate, hope you're well.
Really enjoying the justifications for why you choose a particular design
Would aluminium copings be an option instead or are they still prone to the joints failing?
Thank you, Tom. Aluminium copings would be bombproof mate, there are lots of options that would be too, but they wouldn't match the rest of the design which is something that I should have mentioned and will do in the next video, nice one for pointing that out! Cheers, pal, thank you for watching.
hey mr a just got here not seen yet hope you lot had a good week ? ... guess ill find out in a mo ......
Yes mate, great thank you. Hope yours was too. Hope you enjoyed the video. All the best.
Have you been away Adam descent tan you got there!
Why thank you! It's the Great British weather, mate! Hope you're well.
Tying the parapet into the timber joists and ladder frame, will that not risk cracking the mortar when the timber moves? Or is it strong enough to withstand?
Brilliant serie btw! I'm really enjoying it. 👍👏👏👏
Shared a link to a friend, and they asked if jasper carrot was now a builder
Haha! That's not the first time that comparison has been made! Cheers, Flashy! Hope you're well mate.
Peaky Blinders will be paying you a visit Mrflash ...
Why use the standard OSB board? Surely, it should be waterproof (green) boards
OSB3 is quite water resistant, it will be covered so its only at risk dring construction, methinks
Lots of waffle, fortunately I like waffles!!
Ooooooo....I do like a waffle!!!
Quick i need the does and don'ts with the fixings!! Sharpish 🤣🤣👍 great job lads! But all of that effort to then grp it?? Also quick q with the vapour barrier would it be ok to put it over the top of cavity closers which are going in a parapet cavity and then dpc then coping/ (or) aluminium trim 🤔🤔
Haha! Sunday will be here before you know it! The reason that you don't vapour barrier all the up is because the GRP won't stick to it, we need bare OSB for that, but cavity closers would be totally fine for it mate.
hi pal i asked on the last episode how the fundraising was going but didn’t get a reply. i know you must hundreds but just want to check how it was going. cheers and i love the channel top lads
Hello Andy, hope you're well, mate. Really sorry for not getting back to you sooner, I do remember seeing your comment and I meant to reply. It's going good mate, we haven't really pushed it of late so we're due to give people an update. Can't quite believe people gave so generously. We'll update everyone soon. Sorry again mate, take care.
Great progress lads, eating through it!
Can I ask why the joists ends are penetrating into the cavity? I would hesitate having timber penetrating the cavity.
Regardless you are doing great work.
Cheers Kev! It's so the ties would reach the brick work. The ends being in the cavity won't be an issue mate. Hope you're well.
Very interesting,and really sensibe explanaions as well...I'm sure I'm missing something,but I can't see any provision for the drainage,ie,will it drop through the roof,and run [initially]internally,or will it exit via the parapet wall at the lowest deck level?
It's there mate, all will be revealed in the next episode! Thank you for watching, Mike. Hope you're well, mate.
I used Alutrix on a warm roof and it was a nightmare because it was so sticky.
And expensive! Great product though. Cheers mate.
@@mrabuilders6723 yeah I used it because it was recommended by Steve from London flat roofing. He’s really good and gave me free advice for the building I was putting up in Cedral. Took me a while but was great when I finished. Steve’s on TH-cam and worth a look if doing any flat roofing and goes into cold barriers.
@@riptiz www.youtube.com/@SteveRoofer
@@DICEGEORGE yes this guy is great. Gave me free advice and even highlighted some alterations on my photos during construction.
It looks like glasswool in the parapit top wall. Why not use Rockwool which is more resistant to moisture?
It's just what we had on site, mate. Hopefully no moisture will get in there!
Maybe take the sticky sheet up higher than 150mm , beyond the PIR ?
Any cats today?🐈🐈⬛🐈🐈⬛🐈⬛🐈
You'll have to wait and see...but I think that you'll be happy...
When you built the 2 nibs of blockwork at the start of the video how did you tie them to the other structure, as it appeared that there was just expanded metal strip in the mortar joint ?
I noticed that also.
Pretty sure I see ties in the existence wall
@@way661 Could be would make sense
@@amazing451 think there was ties into the inner and outer nibs too
I'll show you all in the next video, fellas. Cheers everyone.
Great video lads ! What size OSB aboard did you use for the flat room bottom layer and top mate ?
Hello Dean, thank you for watching, mate. 18mm on the bottom and 11mm on top. Thanks again mate, all the best.
In the last video when Rich was fitting the joists he let them protrude past the front of the wallplate by 125mm, was that so you could secure the wall ties into the joists ?
That's exactly why mate. Cheers man, all the best.
HI Guys, i am looking to order the same vapour barrier as you've used. However i thought the OSB needs to be primered with FG35 primer or similar. I noticed you haven't used a primer. Can you tell me why please? Sorry to ask, as its hard to get the answers for the detail. Thank you and keep up the great videos. Ian
Hello Ian, hope you're well mate. If you buy the exact vapour barrier and your boards are bone dry and clean, you won't need a primer as this stuff is extremely sticky!
Excellent content. What's your day rates? I've got a tarmac floor in an enclosed car port which I want to take up and relay with DPC and concrete in Kidderminster.
Our email is in our bio if you want to get in touch, mate.
3mm gap between OSB boards for expansion or not ? Thinking of cutting gaps after ive put the boards down over the next few weeks....
If you use tongue and groove OSB just glue them together job done
We haven't left a gap in this instance, we've used so many nails and there's resin to go on top...I don't believe that they'll be an issue.
@@mrabuilders6723 thinking again on mine if the osb does expand it would just bow downwards a bit which doesn't matter much... But the bow out would suck in a tiny bit of warm moist air to the new curved space !
@@frog-eye1420 i've already bought non tongue and groove and cut them roughy to size, drat
Adam did you use a drone for the footage at 35.01? Nick
Yes mate, it was the customers. What do you think? Shall we get one?
@@mrabuilders6723 Adam - yes brilliant idea - I remember you said in last video that your camera battery went flat and you used the customers camera but didn't realise it was a drone until I saw you putting the breather membrane down! they are brilliant things for overhead film footage - I believe surveyors use them for inspecting wind turbines. 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. Adam thanks for taking the time to answer - it must be quite time consuming answering all the posts. By the way - where's Arthur Askey!! is he on another job? look forward to next instalment - regards Nick
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 ....
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.
@@mrabuilders6723 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 ? Surprised BCO is happy to lose the internal skin ? google Tony Tray for a very easy way to achieve excellent air tightness when building in joists.
They are bloody clueless amateurs, that think they know more than an architect and structural engineer.
I have never heard such codswallop talked. The lack of intelligence and logic from this pair is unbelievable. 😅
Apart from everything else wrong, OSB ?.😅
what about squirting foam down the thermal fixings tubes afer the screws have been screwed?
Yep! That'll work!
also the maths is a lot harder doing firrings in 2 dimensions at the same time, more likely to make a mistake !
I'm leaving my wooden rafters visible from inside - not covering underneath with plasterboard
I don't think that we'd be allowed to do that under the fire reg, but it's a lovely finish to have.
@@mrabuilders6723 oh I hadnt thought f that, maybe strips of plasterboard under the OSB so thats not visible but still beams visible ?
@@mrabuilders6723 or full sheets of plasterboard on top of the beams and under the 18mm OSB and kingspan and 12mm OSB and EPDM?, would if be strong enogh to take the weight without crumbling? I guess so, but worrying ... twould mean a cleaner look at the rafter edges from underneath...
@@mrabuilders6723 or intumescent paint under the OSB - which would be best to do before fitting it - will ask building inspector....
Great video, whats the finished height of the parapets?
Should be about 150mm, mate. I'll know more tomorrow!
What's bigger, your dimple or Richards table saw?
I don't think you quite appreciate the size of Richards table saw...
Entertaining and educational but I am concerned about poor safety, for example did you not think about a temporary cover over that skylight opening?
They're grown ups. :)
Don't worry, Martin, no unnecessary risks are taken at any point! Thank you for watching, mate. Take care!
In body only!
Two Guns Mick on the roof is it?
He'll be there, Paul!
DON'T FORGET THE CAVITY TRAYS THIS TIME!!!😅
Paul! You're back!!! So good to hear from you! I was worried for a little while as I thought something had happened to you but here you are, like a 'phoenix' from the flames!!! Hope you're well old chum.
@@mrabuilders6723 I thought you might be getting worried. 👍🤭
Im sorry , did I miss where the rain water runs off the roof ? I dont see it.
Hello Bob, it's all explained in our new video. Hope you enjoy it.
Rain water from the warm flat roof is going exactly where?
When you say "exactly"...do you want the measurements to the millimetre or just ballpark?
@@mrabuilders6723 ballpark.
@@mrabuilders6723 Because you put all the self adhesive membrane on and then you have this huge slot just between the house and the extension. Hope that the water isn’t going that way.
at 1:12 why didnt you tie in the nibs to the wall?
Nibs are tied into the extension if you look close enough
They're tied in mate, within an inch of their life!
Cheers mate.
I honestly dont know how you can work in sutch chaos, a little effort in maintaining a tidy site really wouldn't go amiss.
Weather has been a nightmare this year.
Here he is, Captain Gloom is back with another one of his motivational speeches! I honestly don't know what you're seeing, Paul, but it's not the same site that we're working on. Thank you for watching though. Hope you're well.
Love your videos but can you stop calling a joist a rafter please
Cheers, Nath. Glad you like our stuff. What makes a joist a joist and a rafter a rafter then?
@@mrabuilders6723 a joist is flat and a rafter is pitched
Hi Nath this is Rich. A rafter is a member used for a roof and a joist is a member used for a floor. It’s a flat roof rafter. 😀👍🏻
@@mrabuilders6723 haha very good but still not correct. It’s a roof joist, case closed
@@mrabuilders6723 Rich are you pulling my leg?
You seriously need to sort out your volume, which is almost unintelligible at the start of the video.
Soz! Do you mean the bit with the cat? I didn't have my microphone on then, but I think the rest was pretty consistent?
@@mrabuilders6723 I think they mean inside the white room talking about the box. It isn't /that/ bad that it's unintelligible but it could benefit from some clarity, maybe a change in mic or volume.
gonna have to watch this in between periods of the florida/tbay playoff game
Which one are you rooting for?
@@mrabuilders6723 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
@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!
@@mrabuilders6723 every year they tell us..."it will be different next year....i promise"....bwahahahaah
theres some kind of amalgamating tape could seal where the fixings go through the vapour barrier? or is that too niggly?
vapour barrier will self seal to a degree where a screw goes through
Cheers mate.
It's a good point you make, and frog-eye is right. Although it is a little design flaw, I must say!
