Cold Roof Insulation | Expert Tips Inside

In this episode we will be installing all the cold roof PIR insulation complete with a guide on how we deal with spot lights within the insulation.
All of the internal ceilings and the basement ceiling will have rock wool insulation installed meaning that we are ready for fitting plasterboard to all the walls and ceilings. The only walls left to do then will be the basement walls which will be done once the tanking is completed.

THE BEST START TO A VIDEO EVER!!! Beers gone all over the living room 😂😂😂

[@SBODevelopments]

Milwaukee table saw for cutting insulation!!! You lads are making some money!

[@mrabuilders6723]

@s3an175 😂 I use it for everything it’s a great saw I just swap blades in and out 👍🏻

[@noskills9577]

Thanks for being the one and only builders I’ve ever seen allow for spotlights when insulating/boarding - a small amount of faith restored in the trade 👍🏻

[@markwarren3590]

House is really coming together now, every build you guys do your attention to detail when doing the insulation is impressive.

[@smellypunks]

Its all about detailing when it comes to insulation. One small area without any insulation will undo all the good work of a large area with thick insulation.

[@grahamparkyn1590]

Yippe twice a week, yesterday was a downer without your vlog….👍😂

[@kurtinbloom]

Intro was brilliant 😅 Luv this channel 👏

[@Sarge084]

Electrician (retired) here: When working on jobs like that my favourite part was coming back after plastering for the 2nd fix. The place always seemed pristine and tidy compared to the chaos of the 1st fix, and a damn sight closer to completion. My day was back in the 70's and I wasn't at all sorry to see the back of extensions, refurbishment and rewires and get into industrial work.

[@gadjules7334]

Excuse the language lads but fucking hell did I laugh out loud at that intro - brilliant! Entertaining and informative, your videos never disappoint. Cheers

[@paulf2529]

I might just copy the way you did the celotex around the down lights on my next job. Good idea👍

[@DICEGEORGE]

oh youre going to add another layer underneath and tape all the joints, that should be a lot cheaper ! I'd tape the sides in the light holes too as i think water vapour could creep through the sawn ends

[@Doug....]

Thats really moving on at a pace now Richard. Once that insulation goes in you can really start to see the rooms coming together 👍👍

[@brendanmaguire4134]

Possibly 2 videos a week. . Nice 1 lads.. 👍👍✌🇮🇪

[@michaelevans2975]

Love the overlath chaps, so simple but neat👌

[@karlsacher9054]

Twice a week, nice one guys. Looking forward to them.

[@Mrdogface12]

Happy days. Look forward to Wednesday as well 👍

[@JurassicJungle]

Looks like nice tight fitting panels using a table saw which is great to see. I have used a festool insulation saw which creates a lot less dust when used with a dust extractor. I am less convinced with tape on all the off cuts upstairs as I think that tape will peel off over time. Did you do the additional layer over the top upstairs? It looks to be a bit less of a vapour layer than downstairs but you may not have filimed the final finish.

[@mrabuilders6723]

If I’m convinced about one thing it’s the silver tape not coming off. However, we did put the 25mm over the top and taped the joints again. 👍🏻

[@tkthebear984]

That was some serious insulation work 🙂. Looking forward to Wednesday’s episodes, absolutely smashing guys. Keep the good work up 😁👍

[@jruk1981]

Did somebody say Bi-weekly content? Yes. Great work chaps, looking forward to it already

[@w.o.o.d.y]

Fairplay, you two got a few big days work done there. You moved that quick ya hair blew off !! Nice one guys. Proper workers, not scared of hard work.

[@donoconnor4204]

Great video and that house will look fantastic! It’s certainly taken on a new shape after all that hard over head arm work. Wednesday night will no doubt just demonstrate how passionate and how good you are as a TEAM! Hope it’s longer than 30 minutes??

[@michaelanderson8010]

Excellent news! Looking forward to tonight’s new video!!!👍👍👍

A 31 minutes video and not one cup of tea drunk. Lads whats going on. Looking forward to the 2 video a week. 👍👍

We were just too busy lazylad or did we just drink loads off camera I couldn’t possibly comment. 😂

Sunday and Wednesday videos 👌👏🏻👏🏻

[@steviek5138]

2 Vids a week😮 awesome 🎉🎉

[@MsNoiseR]

Great video! now I'm going to add additional 25mm kingspan to my kitchen extension too! Dumb question: why bother insulate with Rockwool the ceiling between floors? Sound proofing or just better temperature control of the area?

[@leeedwards9994]

just got here mr a hope you lot had a good week ? judging the thumbnail id say not sure at the min .......

[@KEVIN-x9n]

Excellent as always plus a great bonus Wednesdays thanks best biulders on KZbin better than Steve and Alex

[@TheWebtuts]

Great job with the insulation

[@stevemull1673]

As always, top job guys.👍

[@pwithnall]

Fantastic work on avoiding cold bridging. It really is important and it’s good to see. Don’t know if you’re planning on doing so, but you might want to tape the ceiling perimeter into the wall downstairs. Plaster won’t work as a vapour barrier at the wall/ceiling joint after a few years of seasonal contraction/expansion (get hairline cracks). You can see it happening in older properties by looking for discolouration of loft insulation at the heads of stud walls. Contega PV or Contega Solido (or similar) tapes will work nicely.

[@mrabuilders6723]

It’s all got to be tanked and then another wall put in front of it. We will be putting a vapour barrier on the new stud wall as well. Thanks for the advice 👍🏻

[@pwithnall]

@@mrabuilders6723 Sounds like a plan! Great stuff

[@peterharkes1465]

Fantastic guys! 2 videos a week... you are spoiling us.. love this channel. How did you fix the 25mm pir boards to the joists? Cheers Peter

[@mrabuilders6723]

Thanks Peter. They were only temporary tacked on with some lath nails because we fix the boards up with 60mm dry wall screws. Just make sure you knock the nails well under the surface unless the plasterboard will sit on the nail head. 👍🏻

[@ABjoineryserv4059]

Looking forward to the Wednesday videos

Brilliant content looking forward to two vids a week. As I listen and watch using earphones can you be a first on you tube and limit the sound of timelapses. ta. Keep up the great work.

[@mrabuilders6723]

Hi Brian. When you say sound in Timelapse’s do you mean still playing the sound of the footage but speeded up or do you mean playing music over it? Thanks Brian 👍🏻

[@brianwadhams1518]

Lower the sound ​@@mrabuilders6723

[@brianwadhams1518]

@@mrabuilders6723 sound level is too high when on time lapse [ same on all other chanels] nothing wrong on your part as I see it but I have to lower sound level and raise again to follow 'live speaking'

[@BillsAllotmentDiary]

I've been told that you should never use expanding foam where wiring is. As it allegedly reacts with the plastic on the wires which could then result In a fire hazard?????

[@mrabuilders6723]

Someone else has said that as well Billy. I’ve never heard that before this week. I’ll have to ask our sparky and maybe even do a little section on it in one of our videos once I get all the facts. 👍🏻

[@m0aze611]

Thanks

[@mrabuilders6723]

Thank you very much for your donation it’s very kind of you. Enjoy the rest of your week 👍🏻

[@piripi51]

From NZ: What is "Pink board" Cheers Phil

[@mrabuilders6723]

Hi Phil it’s a plasterboard that is a lot more dense and made to withstand fire for longer periods than standard plasterboard. Ideal for around steels etc👍🏻

[@littlewingpsc27]

In order to maintain the vapor barrier in the pockets for the spot lights, you don't need to tape the vertical sides of the exposed foam too, where it is not covered? Just the horizontal surface is enough? Since the bricks and blocks are not water tight, and do allow some level of moisture to pass through them, do you find your fiberglass insulation has mold issues over time due to the moisture, or gets damp and loses its insulation efficiency? Just curious as we do this differently on our side of the pond.

At point 11.25 on the video did you mitre the offcuts parallel to the rafters, so you could push them up into the void, as the head plate was overhanging. Hard to tell from the video because of the timelapse.

I did yep 👍🏻

I would, will be, be very surprised if the customer ever needed to have the under floor heating on. Perhaps an hour on a winter's day.

[@stevem7868-y4l]

Are we predicted to have artic weather soon in the UK? as the insulation is North pole spec, not a damp island in the atlantic

[@mrabuilders6723]

I think you’ll have to take that one up with Building Control. 👍🏻

[@beatsandwarts]

Fantastic videos! What’s the rough cost of this build? Looking to do the same type of thing, kitchen extension with basement dig below it in Bristol.

[@bobainsworth5057]

Are those lights going to be LEDS or regular resessed lights ? We have resessed lights that are air tight so it keeps insulation off box and doesn't overheat.

[@therealdojj]

Hello, how come you've missed the normal Sunday scheduled slot then guys? You've fans were disappointed that they're was nothing decent to watch on the telly 🤣

[@mrabuilders6723]

Your not far off wrong with nothing decent too watch. It was very nearly a waste of time postponing the video wasn’t it? 🏴󠁧󠁢󠁥󠁮󠁧󠁿👍🏻

[@Mello-bw7tx]

Them masks aren't CE marked or approved products for European use so I wouldnt be using them lads. Only reference in technical documents is to EN14683 which are for the light weight surgical masks in hospitals for saliva & blood so not suitable for this type of work. To protect yourselves against dust particles you'll need EN143 masks & no need for a carbon layer. These masks are a gimmick for this application, BTW I'm a respiratory test lab manager so I know what I'm on about. I've followed your channel for ages so I wouldn't want any harm to come to you guys as Mr A's channel is brilliant 👍

[@mrabuilders6723]

Thanks very much for the advice Mello it is very much appreciated. Consider them in the bin then for anything other than light sweeping up. Thank you for thinking of us 👍🏻👍🏻

Is it Wednesday yet😂😂

[@shavenhaven6869]

Cold roofs don't work. That's why they are banned in Scotland.

[@mrabuilders6723]

Does that mean that heights above ridges can be exceeded on flat roof dormers for loft conversions to allow for the insulation build up or does it simply mean that you can’t have a dormer if you can’t get the height below the ridge? That’s interesting to know. If I never had to do another cold roof it would be too many I detest them. 👍🏻
