Time to get insulating again. We have done lots of projects involving insulation especially PIR, it's always a rubbish job but it has got a little easier at least.

I don't think there is anything more amazing than the entire family literally building their own house with their hands; everyone is helping out and getting involved! The amount of love and care that goes into this project is amazing!

@paulthompson5416 Год назад

Omg Tim I’ve been watching TRC for quite a few years now, and just realised today how big the girls are getting!! How time flies

@AMG63 Год назад

I've spent the last 2 days fitting pir insulation boards in my garage conversion, I set all my timbers at 450 centres to get 3 equal strips from a full sheet. Everything was a perfect friction fit and no expanding foam used, I used a jigsaw with bosch insulation blades and they worked great 👍

@LocostR1 Год назад

Those Bosch insulation blades for the jigsaw also work really well as a hand held blade if held tight in a pair of mole grips. I bought the set of 3 blades and initially used them in the jigsaw but I found I could cut squarer with the blade held in molegrips run a few times along the face of a long spirit level to get a good 90 degree cut.

@danwalker84 Год назад

@markdebcam Год назад

I have used a Bahco insulation cutter, achieved good results, no teeth, like a big bread knife. Love the channel.

@andrewlightfoot1323 9 месяцев назад

I've utilized a very long, extremely sharp Fiskars machete for cutting rigid foam insulation boards, using a stainless steel straight edge as a guide. It works very well for me, & is a clean method.

@thewatermillscotland Год назад

Bosch T 1013 AWP jigsaw blade. Bought one recently for cutting out roof windows in the fiber board insulation - wish I had found them last year. Absolutely effortless, no mess, super clean cut, advertised for PIR board too. Basically a bread knife in jigsaw blade form.

@NewcastleMatt Год назад

mmm added to the shopping basket

@TheRestorationCouple Год назад

Looked at those a while back and completely forgot about them. Will pick one up for the last wall of WFB I need to do next week. Do they stay square through 100mm though?

@Shane_O Год назад

They do work only problem is the dust…. (In an urban city job (windows open etc ) that can be a nightmare.. The jigsaw blade with some form of dust extraction then your away!

@georgejohnson140 Год назад

I use these blades with dust extraction, really quick and pretty much zero dust. I have had a few occasions of the blade not staying square but that might be me, the other thing is that the blade gets crazy hot so watch where you put it down. There are other brands of the same thing, I have an 80mm one that I used for a job with 70mm boards which stayed much more square.

@AJLintern Год назад

I found with the insulation blades that if you score both sides of the foil first and then get the blade in the cuts to start with, it effectively guides the blade and its less likely to start wandering off line.

@jonb8241 Год назад

Great work as per usual… great to see the whole of the family getting involved 😊

@michaelrichards9814 Год назад

Just insulated my loft hatch. Pizza cutter worked great!

@user-tenbellies Год назад

I used gapo tape and it did 90% as you mention, on subsequent projects i have cut and fitted the insulation +3mm and pressure fit (with a squirt of foam) as im placing the joists,beams. Progress is significantly more rapid. Need to sheet it asap as you build Nice job as ever Tim 😀

@alexinnes402 Год назад

Making great memories with the kids. Amazing to see

@havemotorhomewilltravel1154 Год назад

To cut the boards I use a thin non serrated kitchen knife cuts all the way through with 2 passes on 100mm boards no dust clean cut. No flipping of the boards.

@clivedeer6211 Год назад

Hi Tim, I've used a Japanese pull saw when cutting insulation, the blade is thinner than a normal saw and dust is not too bad at all

@jimh4072 Год назад

Great idea 👍

@Riversbend710 Год назад

I like seeing that our girls are going to grow up feeling they are compitent.

@Wilkinson77 Год назад

I've recently completed the roof in our renovation project and used 2 layers of 75mm PIR along with that tape for the performance gaps. I'd read about special soft material blades for a jigsaw and bought some Bosch ones. They are amazing! Accurate straight clean cuts, and ZERO dust or debris. I'd highly recommend them if you need to cut boards like these (bit late for you @therestorationcouple I know) but a complete game changer when using this stuff.

@DebsHill1 Год назад

loved seeing the kiddos helping. maybe they will get the bug and become tradies

@MagicianMan Год назад

Don't quote me on this but I have a feeling that the new Part L (Conservation of fuel and power) Building Regulations now require the use of that Gap Tape on PIR insulation when being used. OFC that applies to the spaces where you have to comply with the regs in the first place.

@snowlion2339 Год назад

I think your right, there’s an entire section now on nothing but insulation gaps and thermal bypass and the tape is one of the recommended solutions

@athloneduke Год назад

Tim/Jo, loved it, who'd have thought of the pizza cutter....hopefully a snug home soon

@paulwakeling7501 Год назад

Hi Tim. Enjoying the latest series of farm / build videos. I used a jigsaw with 100mm blade and a dust extractor attached. It wasn’t perfect but made it much easier to cut and quite quick. Still found some pir dust so a mask was still needed.

@jamesgibb9737 Год назад

A very sharp full size kitchen knife seems to be the best technique I've used but I've not tried the pizza cutter!

@thomashynes5246 Год назад

FOR EXTRA HOT WATER USE A LENTH OF 10 MM COPPER PIPE WOUND AROUND THE CHIMNEY PIPE OF THE WOOD BURNER STOVE LINKED TO AND FROM THE HOT WATER TANK .THE COPPER IS SUPPLIED IN A ROLL AND IS ANNEALED TO MAKE IT SOFT AND FLEXIBLE THE ONLY PROBLEM MAYBE THE DISTANCE FROM WOOD BURNER TO THE WATER TANK

Oh god we have 24m of roof to do with all the rafters at different widths, I wish we had a roof as symmetrical as yours. We have 100 sheets of 100mm and 50 sheets of overboard to do. Thanks for the pizza cutter and floor scraper tip, it well might be simpler and cleaner than our circular saw.

@florahibernica Год назад

I've been there, with an older roof. It was a long tedious job, but nothing takes literally forever.

@Mc674bo Год назад

Hi all Yes the dust is definitely an irritant , I would stick with the pizza cutter especially with the children around . The tape is new to me , and is a bit of a game changer but it’s not exactly cheap . Being able to size your rafter spacings is definitely an advantage, in older properties the approach to the spacings was often an add hock approach which means your caps are all over the place . So that tape could have definitely made my life a bit easier when I did my project 😅 Best wishes as always. 👍👍👍

@paulphillips2941 Год назад

I remember robin clevett doing a video about knocking a table up to cut PIR with his festool insulation saw but I think it could be used with a recip/jigsaw instead if you used an insulation blade 👍 dont know if the depth of cut would be enough for 100mm but certainly 50 & 25mm.

@NeonXXP 9 месяцев назад

You absolute beauty! I am about to do all the stud insulation on my timber frame annex. I used a skill saw for the first bit and it made so much dust. To Amazon for a deep pizza cutter!

@TheRestorationCouple 9 месяцев назад

Either this or the Bosch insulation jigsaw blade is great too

@richardnaylor3300 Год назад

I use a Bosch PIR jigsaw Blade, It’s like a serrated breadknife but in a jigsaw, quick and no mess!

@DavidMeggers Год назад

Does the sharpness of the pizza cutter last, or have you found a way to sharpen it? Really like that all the family get involved with everything, great stuff

@TheRestorationCouple Год назад

Not sure they are ever that sharp. It works best if the line is cut with a knife first however that just adds another step.

@davidclarke3643 Год назад

I used a sharpened 50mm flexible paper scraper, I sharpened the end and one long side and dragged it towards me.

@BillsCountrysideAdventures Год назад

Great idea pizza cutter, nice and clean, well thought out :)

@aidenjohns8248 Год назад

for cutting insulate get an old saw and grind off the teeth and into a knife edge!.. but like the pizza cutter! could do with being bit bigger! but like it!.. coming along guys looking good!..

@CRAZYCR1T1C Месяц назад

That pizza cutter is a genius idea. Patent it and sell the idea

@johnmit Год назад

With PIR it's not just the dust or the cost, but the glass fibre mesh some manufacturers love to embed in thicker boards. I always end up with a few tiny glass fibre splinters that can be nearly impossible to see and remove, but hurt enough to be really irritating. By the fourth sheet I've normally given in and put gloves on.

@dougsaunders8109 Год назад

Is that a Festool pizza cutter right colour 😂 Has to be cheaper than their PIR saw 👍🏻

@Liam.... Год назад

You will be able to heat that cabin with a light bulb I recon. Whats your plan for it once you have your main house built, holiday let maybe ?

@gerrym4377 Год назад

Husqvarna chainsaw, makes a right mess but it’s the best fun for cutting PIR 😅

@christophergreen2345 Год назад

An idea for cutting insulation..... I used to use a normal handsaw but with the teeth removed and the edge sharpened to cutting large bits of foam. Its basically just a a huge knife with a handle and I would hope it would slice through the insulation,. plus you can maintain the sharp edge.

@tobysherring1369 Год назад

If your cuts are straight, could you not combine some of these 'wasted' strips to make one large sheet? If you're cross-boarding with more PIR, and you use tape, your gaps will be minimal.

@bernstangroom6952 Год назад

Wonderful reaction from Jo @ 3:37 😀

@Shane_O Год назад

Oh the joy of PIR insulation. I’ve tried all sorts of cutting tools. I hate this job. The noice of it cutting also grates me😖😖 I’ve tried the jig saw and serrated …. nope! No good…. The blade moves and dust everywhere…. As you mentioned Festool do a purpose saw with extract but it’s expensive….. but worth it if you have a few big jobs. But after watching this and I’m doing an extension soon I think I’ll by one…. 😀 Best of luck with the rest of it!

@TheRestorationCouple Год назад

Give me back my sheeps wool any day! Key to PIR is to stick with warm roofs or external insulation and deal with full boards only imo.

@Shane_O Год назад

Good shout…. Like you on my last project I had an old house…. 450mm centres! No chance. Robin Clevetton his big build series on RU-vid was very good. Watch the whole thing…. Its like Netflix for building nerds! Loved it!

@boomish69 Год назад

We use one of the fine Japanese saws , super sharp & goes through like butter, the other thing is if we have we insulate from the roof down , sounds weird but it’s a bit easier especially on the eves, it slots down into any hangers. Impossible to do from below.

@dmarriott9701 Год назад

Hi Tim and all, what I want to ask is how many electric shocks have you had from unwrapping the PIR. Myself and my wife have just moved a lorry load of the stuff for our son who’s doing a huge extension on his bungalow and as we’re weakling pensioners had to split the packs from triple boards to singles. As we removed the plastic wrapping and touched the silver foil covering the insulation,the static electric generated by removing the plastic decided to go to earth via us. Made us a bit wary but also made us laugh.

@TheRestorationCouple Год назад

Yeah you do get the odd zap but with the daily electric fencing moves on the farm I squeal more when moving the sheep. 😂

@1973scotia Год назад

OMG, i can't believe you let your wife use that pizza cutter with her hair down like that...ha ha.....keep up the good work as always

@joethornber9397 Год назад

My builders swear by the long Milwaukee 25mm snap off blades, they have a long blade and the MW ones are really thick and don’t accidentally snap. Trying it myself next week.

@bobx2387 Год назад

You should not have children on a construction site.....They might learn something and will never forget the experience, but, worst of all they might have FUN... Good on you two for taking time to encourage them to help ( the things they will tell school chums) and be part of their new home. With all the crap that is going on around us with a "jumble sale government" your story is heart warming and gives cause for optimism Bob (Weston super Mare)

@thomass8362 26 дней назад

If the UK is anything like the USA and the kids go to school and tell their mates and the Teachers that they are working in building a new house, you may be arrested and charged with forced child labor! No joke mate, but it's gotten totally mad across the big pond. I almost forgot to add that using an adjustable length carpet layers knife works great on that PIR.

@wolstenholmess8148 Год назад

Inspired by this I revisit the use of a jigsaw (with insultation blade) for cutting PIR board. Previously I've found it wasn't that great - the cut was rarely square. The way I resolved this was to run a stanley knife down both sides of the board for the cut. This prevented the jigsaw blade from wandering, and now gets a really nice (square) cut. This should prevent the need to clean the snapped part of the cut, and slightly reduce the airborne particles.

@myrahouse2368 Год назад

@memphisrainesgallery Год назад

Just a thought about the insulation reaching the ridge line when you where pushing the small sections up over the beam, did you cut an angle and push both sides right to the centre to seal the ridge? an extra, small section would be needed to allow the angle to insert over the beam ( or stud wall) push it tight up then slip a square sided filler block in to seal the gap left

@matthewwatkins1854 Год назад

I tried a bread knife, bahco insulation cutter and normal saw. Bahco was useless on 150mm insulation. Quickest way normal saw, but a lot of dust being the down side

@michaelhorn5633 Год назад

i replaced the saw blade in my rage 5s with a Diamond Blade , blade was same diameter, same bore and 1.5mm wide , i can rip up to 605mm wide and 80mm deep , cuts like a knife through butter and no dust ,

@JasGawera Год назад

Could make a giant pizza cutter from an old saw blade. Maybe with a track to guide it and long handle so you can stand up.

@truckdriver131 Год назад

Hi, Two questions: 1. Do you push your PIR insulation board tight to roofing membrane? If so how about ventilation gap??? 2. You planning adding 25 mil PIR boards as well and then timber battens how you planning fixing it? Through 25 mil PIR board straight into roofing joists using longer screws??? Cheers

@TheRestorationCouple Год назад

50mm space above pir and yes battens below as you say. 👍

@paulluggar5964 Год назад

I think you can lay full insulation sheets on top the rafters external and batten on top with long fixings. Much easier and fewer joins?

@TheRestorationCouple Год назад

Shot an espisode about that today. Yes a warm roof is far better and nicer to install, however in the cabin it would not work as half was trusses which were a set height so had to match. It is the way we went for the walls though. 👍

@paulluggar5964 Год назад

OK will look out for that 👍 A sealed air gap is also an excellent insulator. Enjoying your videos thanks.

@jimcub22 Год назад

My recommendation is a builder less mess on me 😜

@oskarsmillers Год назад

🤔Maybe you could try hot wire foam cutter or hot knife foam cutter(on amazon was some Dominox brand, around 70quid)and some different brands too. No dust at least🤷‍♂️ In youtube was even tests with own maked cutter. Welder with hacksaw blade fitted🤷‍♂️

@james-jq8sk Год назад

A bread knife also works well for cutting that insulation...

@-_James_- Год назад

It'd probably be a bit more work, but how much waste do you get if you cut across the boards and butt several pieces end to end for each void? Maybe none, because you can use the last piece to start the next row?

Different application as it is going into the roof. If you watch the flame tests they are carried out in horizontal. Grenfell was a vertical application. Also the tape around the edges means the flame can’t get between the layers

It's one reason why we don't plan to use much at all in the main house apart from under slabs. In reality most of the average house is a fire risk when it comes to materials whether contents or structure.
