Loft Conversion Part 28 - Cut & fit insulation board. Overboarding insulation. PIR board install!

This is part 28 in my series of loft conversion videos where I take you the viewer through my entire DIY loft conversion. In this video I fit the overboard PIR insulation, over the rafter insulation I installed in the previous video. I show you what I use to fix the board, how I fix the board and have a general rant about my dislike for fitting insulation!

Really enjoying the videos and watching this project progress. Miss the Elephant Rescue Plan songs though, thought they were cracking!

Wow, I Identified with this so much as I am renovating my cellar. (Year long project, and before furlough fitting it around a 40-50h job as well.... What weekends, what friends? )

The bits you enjoy get done well and are so satifying... The bits you hate (for me its plastering and smoothing down the walls) you end up doing only a few hours and spend most of it moaning and complaining about every little bit... We've ALL been there. The I in DIY never feels so bad when you are on the annoying jobs

I didn't take videos I took maybe 700pictures instead but i can see just from scanning through the 12h days and so much progress and then... A picture which looks identical to the week prior.

That said. I enjoyed the insulation part of my build. Went from damp walls, tanked and battoned, and it was only once the insulation was fitted i could see the shape and feel of the room.

Ofc I had to redo a fair chunk as I completely revised my plan then... At least electrics were easy :)

Great to see some progress, and whilst you personally hated it. It allowed me as the viewer to visulise the space so much more :)

I have enjoyed watching this series. Nice one dude. Keep plodding on.

Grate job. mines nearly finished and all your videos give great helps and tips what a guy👍

PIR insulation. Think you said it all! Hate the stuff. The dust though is quite an irritant so I’d wear a mask. Also for small boards like that I use a snap off blade rather than a saw. Makes 95% less mess and cleaner cuts.

Love watching this series. And nice to see you're just like the rest of us and get absolutely fed up sometimes! Is the loft now finished?

[barryquinn]

Really enjoy watching these videos, great attitude when learning something you haven’t done before and explaining the problems you had and tips you learned. 👍🏻 Did you have a trade before this or just had a general interest in construction and learned everything on the build?

[livingladolcevita]

I think you mentioned in an earlier video about the stickiness? of the tape, especially if it is cold, If you heat it up slightly with a hair dryer or similar it softens up the adhesive, makes it more tacky

I no how you feel about insulation. I'm in the process of basically rebuilding my 1920s timber framed bungalow to chalet with loft conversion and balcony .the insulation over structural is unreal. I had to have a steel cranked roof .same as tho I'm doing the whole thing myself .iv been in the building game all my life, a bricklayer by trade but do the lot .how times have changed 33 years in the game and always learning. Good luck good heal and keep up the interesting vids

Yaaay 1st yet again mint.... well done with the build

[peterridding]

Good video . Complete empathy with you my friend. I detest kingspan! As good as it is at insulating, it’s horrible stuff to work with .

[shaunmenezes]

how to replace gu10 blub from the celling?

[dalewillis]

Great video and very inspiring. Our loft conversion was done in line with building regs 23 years ago and the insulation is terrible compared to new standards. Watching your videos and reading your replies to questions has given me the confidence to re insulate myself. Just had our roof done with breathable membrane, soffit vents and vented ridge tile, so good ventilation. Following the advice in your video I’m going to remove the old plasterboard and insulation, then replace with 100mm insulation board between the rafters and 20 or 30mm insulation board over.
One question... are the screws / washers used to secure the insulation board galvanised or just standard steel?
Cheers 👍

Currently in middle of this - got a few questions if you can help. I'm wanting downlighters, its a 24ft room - is there any point with all those holes? Also would the electric cables for the spots be ok going behind the PIR thats between the rafters and then pulling them through? Will be connecting the spotlights to existing old red and black wiring.

[philprice]

What thickness insulation have you used between the rafters and over the top?

[haroon]

Can you use no nails glue? Then the plasterboards will be screwed over them?

One other question.. I’m thinking of using just 10mm xps insulation (rather than pir) for under boarding. Between the joists, I have 120mm pir. Will that do? Looks like you’re using 50mm pir, that’s quite pricey.

Great videos. The plasterboard on the ceiling below your eaves cupboard/roof space is it foil backed? Does it need to be? Thanks

[barryquinn]

What did building control say about fire rating the gap between the top of the party wall and the underside of the roof?
