So what I find works well is to intentionally undersize the cuts (by 5mm or so each side). Then jam it in with packers, and fill the gaps up completely with foam. As the foam expands it will 'glue' the board in, making it absolutely rock solid while also eliminating every potential gap. Then you just remove the packers and fill those holes too. Basically like a budget, messier version of gapotape.

Great idea using screws to maintain the air gap spacing. I wonder if one could 3d print a few spacers and screw them in to help align the boards. Will try this on my garage pitched roof.

@berniesinclair1351 6 месяцев назад

What I don't quite understand about leaving an air gap is that if air is comming in vents through the soffit and going up to the ridge board where does it vent out, air will stop moving if it's not vented at the other end, and if you have roof vents you would need one between each roof joist on both sides of the roof.

@GregoryJokiel 5 месяцев назад

This was exactly my concern as well!! Does every rafter pair need to be vented? My roof only have about 6-8 vents on each side where the roof meets the ceiling, no ridge vents. And how can you provide air flow on the other side of the roof if the PIR boards are tightly pushed to the ridge? This is my main question after watching tones od videos on RU-vid and doing my research. Can anyone shed some light? How the rafters without vents can provide air flow when they are closed with PIR boards?

@ebola1974 4 месяца назад

Doesn’t it vent out on the other side soffit? So comes in one side, goes up and then back down the other side and out?

@cmarin5904 Год назад

Awesome. Simply awesome. Thank you. Didn't realize a wood saw would do the trick to cut the board down to size.

@ChrisDadd 6 месяцев назад

So useful. At the bottom end of the rafters, can I stop where the top of the wall is? I'm insulating a garage conversion and wil be using 100mm celotex with 50mm gap above for eaves vents to ridge. Do I also need to tape the end of the insulation board that's exposed to the eaves?

@POUSEaroundtheHOUSE 5 месяцев назад

No need to tape the ends although you can if you want. Yes you can stop where the wall is. I pushed mine as far as it would go whilst remaining flush with the underside of the rafter. You'll find it will hit the wall just before the cavity that way. If you have cavity wall insulation, then might be worth it meeting with that so you have no bridge between the two ensuring the interior wall and roof is all insulated. Hope that helps. Thanks for watching.

I tend to tape just joins between pir to join them together, but I fill all gaps with foam if required. Because I was overboarding (see my other video) there's a continuous layer of insulation across all rafters. But if you want to tape to rafters you can. Best of luck!

@popdroprolld20 Месяц назад

Alright pal, great videos. I know this is 2 years ago so comments are probably dead but worth a go. I bought a victorian terrace and just found problem after problem. Feeling overwhelming to be honest. But starting to insulate the loft. So couple questions... Do these boards cover the amount government say you need. Also i have a vent in my roof i think is for ventilation, would you just board around it to keep airflow? Thanks

@POUSEaroundtheHOUSE Месяц назад

You have to have suitable ventilation when insulating like this. But you need ventilation over the top of the boards either with roof vents or in my case I used fascia vents. This stops condensation under your roof felt. The insulation should really seal the room so you then need internal ventilation via a window that can be left on the trickle vent of a velux on the catch. As for insulation, mine was done as part of a loft conversion so it had to meet a certain standard but if your not making a 'proper' habital room then you don't need to meet those standards but it can only be called a storage room rather than a proper bedroom. Here's a link to my loft conversion playlist - ru-vid.com/group/PL2-FHRIF3qm-skuIrOxfivCGhoE0v8g2n. Take a look through the vids (44 so far!) as I cover vents, insulation, velux windows etc throughout. Best of luck.

@matthewnicholas6365 Год назад

Im looking to create a ceiling in my garage with a pitched roof and rafters overhead. My plan is to wedge this stuff overhead, then screw 5mm plywood under it. If I'm hearing this right, are you saying I should lay the boards up to 50mm higher than the plywood boards, or is the airgap not relevant as I'm not mounting anything against the roof?

@matthewnicholas6365 Год назад

FYI, it's to keep the garage cooler in summer as I'm putting a treadmill and aircon in it. It's like a furnace on a hot day

@POUSEaroundtheHOUSE Год назад

No. The airgap needs to be above the insulation, between the insulation board and tge roof membrane / felt. It's to stop condensation forming above. You also need some way of getting good airflow by using vents. I used fascia vents. If you go to my loft conversion playlists, there's a video of me fitting the vents so it all makes sense. Hope that helps.

@matthewnicholas6365 Год назад

@POUSEaroundtheHOUSE I thought that's what you meant but wanted to check. The insulation will all be directly above the new ceiling with a fairly large space above it as the roof is pitched 4 ways into a pyramid shape. There's something onto that would allow airflow as well. As in, it's not air tight

@jackpartridge7891 2 года назад

Hello I just have a question if you could please answer… I’m looking to knock a wall down to make my downstairs bathroom a little bigger so my bathroom is joined with my W.C however my W.C has only a single skin wall. Can I apply the same method for this with 100mm PIR and also the real question I need answering is: do I leave an air gap or do I butt the stud wall right up against the brick wall? Hope you can answer thank you 🙏🏼

@POUSEaroundtheHOUSE 2 года назад

If you mean a single skin wall to the outside, then best practice would be to do a stud wall with an air gap of at least 50mm, but on the outer most side of your timbers, cover with a breathable membrane, then infill the studs with insulation. You should really put a vent in the outside brick wall to allow ventilation behind the stud timbers and membrane. You can then plasterboard the inside of the stud timbers. That's along the lines of how garage conversions are done and means you should avoid any damp issues. If you want to cut corners you could but it up to your wall but your're likely to get damp problems and condensation in time. Hope that helps.

Excellent tips, just about to start my project. How much space between the eaves and insulation do I need for airflow please? as the eaves are currently covered

@POUSEaroundtheHOUSE 2 года назад

Hi Norman, with old bitumen felt you'd usually be required to leave 50mm air gap from the eaves all the way to the ridge. To achieve the airflow you need either soffit vents or fascia vents which allow the required air flow.. You can see me install fascia vents in one of my loft conversion videos here which may help - ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-TtS4oEyQptY.html

@terryault7128 6 месяцев назад

TCA Hi, I have been looking at your vidio PIR between rafters. Great & easy to follow. In my 1939 3 bed semi I only have 75mm depth of rafter to felt. In your opinion could I use 50mm pir board, leaving 25mm air gap. I dont want to add extra timber to face of rafters,to accomadate thicker pir as this makes the job larger & also adds more weight. I would appreciate your thoughts.

@POUSEaroundtheHOUSE 6 месяцев назад

If you're not doing it to modern building control standards then you could use a thinner board yes. If you have the old bitumous felt then the satandard is to leave a 50mm airgap. I left 25mm gap but I also installed a modern breathable membrane and fascia vents allowing air circulation above the insulation. So you may get away with it but you want to avoid condensation building up above. Hope that helps. Thanks for watching.

@steveroberts402 10 месяцев назад

Do you install insulation FLUSH with roof joists or push in enough to allow space for foam?

@POUSEaroundtheHOUSE 10 месяцев назад

Flush if you can. I only add foam where the cuts are slightly out. There is a tape you can use now which expands onto your foam allowing you to cut board a touch smaller. It's called gapo tape. Hope that helps. Thanks for watching.

@kipmcclelland7640 11 месяцев назад

DO you have to leave space for air flow between roof and insulation?

@POUSEaroundtheHOUSE 11 месяцев назад

Yes, 50mm is standard, which may be reduced with a good breathable membrane. You can check with building control. You need vents at the fascia or soffits to allow the air to flow in also. You can watch me fit fascia vents in one of my loft conversion videos here - ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-TtS4oEyQptY.html. Hope that helps.

@jamestattersall4715 Год назад

Hi. How much room do you need to leave between roof tiles and new insulation board? Cheers James.

@POUSEaroundtheHOUSE 2 года назад

Windows is the obvious solution. I have velux windows which can be left on a trickle vent which is fully waterproof but allows small airflow in/out of the roof space. If you're not using the loft space then just insulate the floor with a mineral wool and get some ventilation in the roof space by either using polystyrene wedges between you layers of bitumen felt allowing air in, or you can use soffit or fascia vents to allow air in also. If you take a look at my loft conversion vids you can see where I used fascia vents for airflow over the top if the insulation, however this will ventilate an entire loft space if you just insulate the floor leaving the rafters clear. Hope that makes sense. Best of luck 👍

@andrewarthurmatthews6685 Год назад

So just to be clear, the PIR is pushed between the rafters with the outer foil skin in contact with the roofing felt / slaters felt ? Then the requirement is for an air gap between the inner foil skin ?

@POUSEaroundtheHOUSE Год назад

No, the gap is between upper side of board and roofing felt, and ventilation is required at soffit or fascias. I used fascia vents. If you watch my other video, I apply insulation over that board on the inside of the room to cover timber rafters as well. Hope that makes sense. Thanks for watching.

Pouse should you not leave a 50mm airflow between felt and insulation for airflow? We are in progress of planning this we have dropped all internal ceilings on 1st floor and will be having a vaulted ceiling. All specs and kingspan are saying 50mm airflow? Good video 👍🏼

@POUSEaroundtheHOUSE 2 года назад

Always check with your building control officer as things change and ultimately they have tge last say. But 50mm is the recommendation when you have bitumen roof felt. I replaced mine with tyvec supro breathable membrane (plus tge use of fascia vents) so I was allowed to reduce the gap but it depends on what your local officer allows. Best of luck with the conversion. 👍

If you fill between rafters you still need a void for air circulation above the insulation and some fascia or soffit vents at the eves. You can get different mineral type insulation that can be used in the rafters but you'd have to just check the spec is suitable for your needs.

Problem with that is you can't guarantee the depth of the foam. So it may not go as deep as your insulation or it could do the opposite and expand into the air void behind which would not only bridge the gap between insulation and roofing membrane (which is bad) but would block the airflow between the two which is essential to avoid condensation and damp above the insulation.

Sorry, but this is utter bollocks. There is simply **no way** you (or anyone else) can get an accurate enough cut to prevent air moving around any given section of insulation. Thus, 80% of your expense and effort is completely *wasted*. The *only* truly effective method of using rigid insulation in this scenario is to undersize it and seal it in place with a *full depth* application of expanding foam.

@TheDanielShepherd Год назад

Hi mate - in my older bungalow loft the sarking has started the perish. I've thought about doing this PIR board for a while. If I could repair the sarking with a breathable patch and then put the PIR boards in - would you then still keep the insulation above the ceiling? So you'd effectively had loft floor insulation, the loft itself, then the PIR board in front of the breathable sarking membrane and tiles.
