I'm learning to do this tomorrow as part of my school transition year work experience, I don't know if you do anything similar in the UK but here in Ireland during our 4th year of secondary school (maybe year 9 or 10 in England?) we get a couple of weeks off to go work. I'm going to be lagging pipes and I decided I'll try and get a head start 😂
Many thanks for this. I'm not actually insulating anything, I just want to cover the rods for the mechanism for my up-and-over garage door so the car's tailgate won't catch when I open it. Didn't realise it was so easy to split prior to fitting.
ive just started my apprenticeship 2 weeks and just yesterday i was told to lag a whole garage that had just had lots and lots of pipe work done with the boiler etc, and FOR ME it was such hard work as ive only started. Getting the corners and lagging tees was so difficult lol

Probably a bit harder to do with the mitre box and I know this video is old, but with the newer lagging tools available that go around the lagging and have the angles cut into them that you can follow, like the Lag It for example, it makes doing tee’s a lot neater. You can basically cut a triangle half way through on the one piece of lagging, and then the other adjacent pipe that comes into the tee, you can cut the end of the lagging into a point which then fits into the triangle you cut out of the other piece. You probably know this by now but yeah just thought I’d mention it
Thanks Al - I had a couple of foot of 15mm copper pipe from my conservatory to my outside tap - I had used this kind of insulation but the pipe burst - onlu just got round to fixing it. Is this insulation OK for outside? Admittedly I didn't cable tie it - may be that was the problem.
I appreciate your helpful video, but over the years I've come to detest this foam plastic pipe lagging. The problem is that the stuff seems to be irresistable to and totally defenseless against mice: they will gnaw on it endlessly and soon turn a run of lagging into a pile of foam plastic crumbs. In fact this is often your first sign that you have mice. And the stuff is not cheap! The mice don't show the same interest in the old felt lagging.
@@dereton33 Don't get me wrong, I'm not saying that felt is always better, only that it may be a better choice if mice are a factor like in many rural properties.
@@MrSwanley yes mice have chewed bits of mine. And urinated on it. It says on some website, “it won’t sustain vermin”, maybe not but they like to give it a good chew. It’s foul. You can get wool that you can wrap around, someone said mice don’t like that, don’t know if that was you, although I do know mice eat wool at times. And they’d still pee on it. You can get wool lagging from Wickes, it was possibly you that commented.
For the Tee.. just do the same thing as you do for the L. Use the 45' for the left and right side.. and then for the center, cut a point. Then just tape the corner. sealed and done.
HOW TO TEST PIPE HEAT CABLE TO KNOW IT ITS STILL WORKING UNDER MY MOBILE HOME .i HAVE A FOAM INSULATING PIPE COVER OVER THE HEAT CABLE. SHOULD i FEEL THE PLUG WITH THE FIRST FOOT OF CABLE GETTING WARM IF IT WERE 38 DEGREES OUTSIDE?
Hello, im thinking of doing this because i want hotter water in radiators and dont want to waist heat throuaut pipes. Hawe you noticed any energy savings after isolation of pipes. Tnx for answer!!!
Hi, this is so useful! One question though - I'm using this stuff to lag a condensate pipe that's bracketed to the wall. Any advice for what to do where the brackets are? The foam won't go around the back of the pipe as the bracket blocks the space.
Quick question for you, would you lag pipe that are on show inside the house? My house is old and I have two sets pipes that go or come from upstairs to downstairs. Would you lag? Thanks Stephen
Hi Stephen. I'm sure Al would agree with me. You don't tend to lag any pipes in living spaces. You only lag outside your house and in the loft, as you loft is regarded as an outside space. Have a great day.
@@dereton33 weird, there is lagging on my pipes in the kitchen. Pipes from the oil boiler come through the stone wall and run up and down walls in the kitchen. In an ideal world should they be behind plasterboard, or maybe boxed in? They’ve got some foam lagging on the ones near the floor, which has all been peed on by mice and chewed. Some of the pipe looks like it’s been painted over, don’t know what’s under the paint, it’s a nightmare really.
Thanks. Really useful. What thickness of lagging are you using here? And what thickness is needed for 15mm and 22mm pipe going under floorboards? Thank you.
Hi Al, thanks for your help. My dining room wall has been showing signs of dampness near some boxed cold air pipes. I called a plumber who confirmed there was no leak. Pipes have a lot of moisture. Could this condensation be enough to cause dampness in the walls. I have lagged them but the smell is terrible. Any suggestions apart from lagging. I have been here ten years and it's not happened before. Walls are stained upto 4 feet high Much appreciated!
No the pipes will not cause enough dampness to condensate the wall. Lagging the pipes is still the best way to stop them condensating which you have done anyway. I would get a builder round to investigate for you.
Great video, thank you! I need to lag a about 1.5 metres of CW pipe where it feeds from the boiler to the kitchen sink, as it's got loads of condensation on it. However the pipe is bracketed close to the wall, and also really close to the HW pipe - so close that foam lagging won't fit in between the two pipes (even the smallest size lagging), and it's really hard to even get foil insulation tape in between the two pipes. Would it be okay to lag the CW and HW pipe together - one piece of lagging round both pipes?
There’s a similar pipe setup from an Oil Boiler outside my house. The HW is next to the CW pipe, there’s a gap between them, but not by much. The previous owner of mine, in the kitchen seems to have painted over the pipes. I’m not sure what’s under the paint either……..
Hi, thanks for all your tutorials, Ive learnt alot from you. One question please, I friend of mine wants an outside for he's working place, only way is to put the pipes through the wall and on to the wall. It's about 28meter long, what kind of pipes do you advice if I use? I have measured if I use copper pipes it's needs around 14 of 2meter one. What's your advice please? Thanks
@@dereton33 Hi thank you so much for replying, that's pushfit fittings than? This isn't going under ground, it will go on the wall. I this case have to insulated the plastic pipes with 15mm insulation lag? Thanks
Hi Al (and Jan), Happy New Year for 2023! 😊 on the cable ties, would you suggest 1 every e.g. 5 inches with one (or two) at either end of an elbow? Recently had a copper pipe split when even though the pipe was flagged (old foam) so have bought some thicker foam and came straight here to find out what to do. Thanks!
Can I put the lagging on pipes that are already coming from my boiler to the wall as they get very hot and I'm worried the kids will burn themselves on them coz the pipes go low down and can be reached by the kids ?

Thanks Timmy.
do u need to lag central heating pipes under floorboards - or just pipes that are outside of the house??? thanks
Under the floorboards as well.
Fast forward 8 years and a packet of 50 ties is no longer a pound, now it's a pound for each tie.
Time flies.
should you lag both hot and cold pipes or just the hot?
Both.
Thanks Al - I had a couple of foot of 15mm copper pipe from my conservatory to my outside tap - I had used this kind of insulation but the pipe burst - onlu just got round to fixing it. Is this insulation OK for outside? Admittedly I didn't cable tie it - may be that was the problem.
Should be fine, when you turn the water off to the outside tap always open the tap to allow the water in the pipe to run out.
Thank you for sharing this. Please where can these be purchased in U.K. for thicker pipes?
Local plumbers store.

Yes, absolutely
@@dereton33 thanks mate
What would you do differently if the central heating pipes were being buried in a cement floor?
Either drop from the ceiling in ducts or chop the wall out to conceal them. Or run around the walls in ducting.
@@dereton33 ok thank you! Will they require any additional protection from the cement to avoid corrosion? Tape or otherwise?

You just have to cut the foam around the bracket Becky, there is not much else you can do.
@@dereton33 thanks :)
Hi Al, you mention using a mitre to make a cleaner end for the tee piece, what angle would you use for that piece? Thanks!
A 90%

Just wanted to make sure, just incase it was better to try and keep the heat to the rad. Thanks for the reply
Stephen Lyons Bernie is right, unless you do not mind the look of lagging on your internal pipes, looks awful.

Pipe laging is a standard size of thickness whether 22 mm or 15 mm.

Not good plumbing practice that. The cold pipe will condensate with the heat from the hot pipe.

You probably won’t read this now, but you can get a wool insulation you can wrap round, guess that would be too thick too.

If your pipes are hot enough to burn someone you ought to turn the boiler stat down, especially if you have a condensing boiler
When using your finger to split the lagging do it slowly, or you can get friction burns
Good advice.
