Pipe Pattern Sizes (ONLY APPLIES TO 3” INSULATION);
(Note: Pattern sizes can change based on manufacturer and other factors)
ALL SIZES ALREADY INCLUDE 2” LIP!
4” = 16" + 2" Lip
6” = 23" + 2" Lip
8” = 30" + 2" Lip
10” = 38" + 2" Lip
12” = 44" + 2" Lip
14” = 52” + 2" Lip
16” = 57" + 2" Lip
18” = 65" + 2" Lip
Notes;
• Make a list of all duct to be wrapped prior to starting and have ALL tools and material required to wrap pipe. You would be surprised at how much time is lost running back and forth to the truck.
• Try to wrap in long lengths to avoid seems and save time (confirm larger sections can physically make it to their intended locations)
• Always connect reducers, end caps and even elbows prior to wrapping to save time
• Do it right the first time! Quality is important AND your reputation is ALWAYS on the line!

I like how he's sharing not just how to do it perfect but how to fix minor issues which are unavoidable on the field!

[@bluearcherx]

if even 50% of HVAC installers paid as much attention to detail as you, the world would be a better place

[@ErikGolfs]

Good thing the ones that know this stuff are the ones making the really good money 💰

[@vixue]

It's very refreshing seeing someone that cares this much about their work. I came to watch something waaay more simple but watched beginning to end out of enjoyment. Thanks.

[@scottschweigert1657]

man these instructional videos that actually show the full process are so rare... you know you're gonna learn something if its longer than 30 minutes. thanks so much

[@mopeooo]

You are a total professional, excellent video, no wasted time , straight to the point and top journeyman craftsmanship. So valuable to have you share years of experience in the trade with the undeserving members of the humongous . I salute you

[@trickhealey]

Those audio J and L cuts by the video editor are awesome. This is the most watchable instructional video I have seen in a long time. Teaching style is phenomenal. Splendid!! Also it is amazing you could get Jack Reacher to be the instructor, I wouldn’t have thought he knew so much about ductwork.

[@marcuscicero9735]

😂 Right!

[@5YEARS4FRUIT]

I believe Reacher did some apprenticeship with John McClane at the Nakatomi Plaza.

[@user-fw9gc1jy5p]

I've been a service l mechanic/technician owner of a commercial hvac/r company in the Austin Tx area for40 years. Your attention to detail is excellent.

[@Jason_MotoPhotoAdventures]

Assembly line process.... Ford would be proud!

[@Xyrium]

See, this is what everyone needs, and HVAC pro who has OCD. ;) Nice work sir. I'm sure you would have blown through 10 runs in the same time as this video if you weren't walking us through it.

[@robertvoller8619]

excellant presentation and I love your Tat We the people

[@johnpryor6806]

I rarely comment on you tube. Outstanding work Andrew. Great in all aspects. Video quality to presentation. It is a joy to see someone who clearly knows his trade. Thankyou Sir! I learned soo much.

[@alexoloughlin5520]

Awesome video; appreciate you demonstrating how to correct issues you may run into or create along the way.

[@johngrossbohlin7582]

Both my brothers were union tin knockers... They did commercial work in everything from shopping malls, to office buildings, to refineries, to clean rooms at IBM chip plants. They did everything from fabrication to installations that included flying in roof units with helicopters. I was familiar with the duct fabrication and installation work from their stories but the details of insulation were never mentioned. From this video I can see why! To do it right requires attention to process and detail and doing that for days/weeks on end had to be incredibly tedious. This gives me a better appreciation for a task they did during their careers.... It also helps me understand what needs to be done to properly insulate the duct in a house upon which I'm working. Thanks!

[@Tony-dk1bp]

It is easy to see that this guy is a top notch mechanic.

[@monkeyfinger7949]

Thank you for this video, Andrew. I learned a lot about insulating hard ducting and was happy that this quality video was available.

[@MatthewPierce9]

This man is an artist. Great video thank you.

[@JerryLynch2]

I left a long and lengthly comment on one of Andrews other videos. The man is Ultra Pro and the quality, impeccable!

[@courtneywilliams9530]

Absolutely best videos I have ever seen! I do some Hvac install volunteering but would love to learn more so I would be faster and more confident. I don’t have time to go to Hvac school so I love love how precise and all inclusive your videos are. Your are definitely a teacher, and would totally use your company if I ever had any AC needs based on your love of the craft and attention to quality.

[@jeremygattenby2183]

Absolute life saver! Taking on my own HVAC DIY project and your videos are invaluable. Thank you!

[@ramchillarege1658]

Excellent videos. You are a born teacher

[@chengtsai8323]

the level of thought you put in shows. Respect!

[@rickmitchell7719]

Thank you for taking your time to some me how to do this. I appreciate it

[@robbenoit6065]

Great video!! Best part, "At this point, you just need to know what you're doing" 😂 based on the video I sure do know what I'm doing now 🤓

[@old1yt]

Taught me a lot with NO BS! Thanks! I can do this now.

[@seanmccormick5128]

Excellent instruction!!

[@fortlauderdalelimopickupco5255]

Awesome job done !!

[@fortlauderdalelimopickupco5255]

Great job!! Thank you so much for taking time a explaining in debth..I learned a lot. God bless!!

[@saramulry]

Informative, but also extremely satisfying

[@rafaelcastillo5408]

Man. You need to hire me. I'm and insulator my self, and we don't have time to be doing all that, when it comes to insulating duct, specially when we have drywallers after us trying to cover them Walls and ceilings. I've been insulating for 19 years

[@lancerudy9934]

Great video😊

[@JeremyRoche]

Outstanding work thank you

[@ron4274]

Exceptional tutorial...thanks!!

[@ritesaidme]

Thank you so much for these videos sir

[@leehrules]

Can you post a video on insulating through a 1-1/2" or 2" stand-off on a volume damper handle? It seems that there are a lot of insulators that are not getting it right.

[@apizalfoshizal]

Great content

[@scottschweigert1657]

all i need to see now is how you wrap an endcap on a round duct! i see you have one in a later video that looks superrrr clean

[@aglmechanicaltips]

End caps are at 17:15 of this video; kzbin.info/www/bejne/j4C7dXargLusqJosi=WyMHQUEolNZHt5bx

[@G4BEU]

Noticed a HUGE difference on the 2 inch crimps . Crazy

[@Lkom24]

Respect to my fellow hvac tin knocker but we do it all!!

[@user-dq9ng5vv6d]

So you got à New subscriber. Big respect 👍

[@lulavaughn7331]

video is AWESOME

[@courtneywilliams9530]

Also, I was wondering if you could explain Hvac 101. I’ve had a couple of people explain AC is taking the heat out not adding air in an try to explain to me the basic components but I still can’t process it . I heard in school one of the first things you do is learn how to make some rudimentary Hvac unit of sorts to understand how each component works together . Could you make a video explaining this ? Your videos are so easy to understand, I feel if you explained it or showed it, I might get it.

[@sellerasset]

Thanks

[@mordeth999]

I always put my screws far enough back(5-6") on the pieces of pipe to where someone doesn't catch a screw in the hand when grabbing the end of the pipe to pick it up.

[@josemotamorales2304]

Great

[@mrbdent]

I have watched several of your videos and am so impressed. I wish all hvac contractors did such clean work. I am pulling out my old R-4 and going with 3” R-8. What size should I cut insulation for 5” and 7” round pipe? I got the info you provided on the other sizes. Thanks again!

[@JDavison55]

Forest Griffin is also an HVAC hero?!

[@Doc02864]

Wondering if the outward cinch stapler will work with a flexible, plastic duct. It’s very difficult to use the stapler pliers with thick insulation.

[@stephengalvan7722]

Don't you want to stagger the seem for rigidity but dang beautiful work

[@rafaelcastillo5408]

And you should of used the duct sealant on every joint, for better air flow. So there's no air leaks

[@fightingstvm]

what insulation are you using and where could DIYers get it? I can't find anything like you are using at any of the big box stores.

[@aglmechanicaltips]

Yeah they aren't going to sell that in a big box store. You need to find a wholesaler who sells it and if they won't sell it, ask a local HVAC company. I will often sell these items to homeowners when they need it. I'm using R8 3" thick but depending on where you live it may be thinner.

[@yodamanrulz176]

Does anyone know the type brand and size of the shears? He is using to cut the insulation????

[@JB-yq9bn]

I found a hard roller similar to a Marshalltown 1-1/2 in. W X 13 in. L Plastic J Roller made techs more consistemt

[@callumross-moretta8638]

Hello from lovely sunny England! I have watched a few of your videos and I find them thoroughly interesting, you're attitude towards quality is excellent and a joy to watch. I do have to sit and keep working out the difference in measurements, from inches to mm though haha. There are differences in how we do things and from what I've seen ducting is taken far more seriously in the States or certainly by your company, a quick question, as I'm looking at potentially migrating to Canada. Is the ducting there fitted to similar specs as it is in the USA? Thanks

[@aglmechanicaltips]

Thanks for the compliments. I wish I could help with your question but I have no idea what they are doing in Canada. I'm sure there is differences though because it even varies in the states.

[@Axel-xs3fj]

Hey, question regarding fittings in the US. In Sweden and most of Europe we use rubber gasket around the fittings to seal them up and does not require to use mastic on the outside. How come you dont use that in the US? All HVAC videos i see is so diffrent from the assembly here like hangers, diffuserers, everything.

[@MundoHVAC]

*Thanks for your video.* Where can I buy the sheet metal to assemble the duct?

[@ogreunderbridge5204]

Should crimping a pipe like that in principle work for thicker gauges ? I´m struggling with a wood stove flue adapter...

[@pamgalicki]

Nice video, could you provide the source link for the insulation blankets and mastic tape

[@aglmechanicaltips]

The duct tape and mastic tape can be found at the links below. The 3" insulation would probably need to be sourced from a local HVAC distributer. Mastic tape amzn.to/3HHVAdx Duct tape amzn.to/3PD7441

[@sg7kirklazarussarg516]

What about just the right amount of mastic even for the gores

[@sg7kirklazarussarg516]

At 255 thought he was going to pull a cigarette 😂

[@scottschweigert1657]

Unfortunately I only have access to 24" x 30' R8 insulation! So i'll need to daisy chain it -- would you recommend doing hamburger or hot dog for installing on 10' runs of 12" and 14" round metal ducts?

[@aglmechanicaltips]

I don't know, 24' wide is meant for repairs only. I would keep shopping or wrap the duct with a seem every 24". You can totally do that and it would be fine just time consuming.

[@scottschweigert1657]

@@aglmechanicaltips I was able to find a 48"x75' R8 FSK roll ---- but doesn't seem like it would wrap all the way around a 14" round pipe?

[@andrewlingle8985]

Your going to have to wrap it long ways and have a seam every 4'

[@thevillageiddiot1913]

Is that just duct sealer that you're using on the insulation or somthing specific?

[@aglmechanicaltips]

It's mastic the same stuff that is used on the metal seams. In my region it is code to have it on the outside of the duct on the duct tape seems.

[@MADProjects411]

Can you clarify the insulation thickness? Are you referring to the out of package thickness or the installed thickness?

[@aglmechanicaltips]

The vapor barrier on the roll itself will have a label that says 3". This is also the average installed thickness of the insulation but as I mention in the video, I go a little tighter than what they outline.

[@carlyleworkman1928]

👍🏿

[@cannon8170]

can i get away with just taping it and no staples?

[@aglmechanicaltips]

No, the tape will slip and fail overtime.

[@LeeFLE]

What’s the difference with applying mastic to the duct seams before insulating vs the insulation itself?

[@aglmechanicaltips]

Mastic is actually designed to be a sealer for the internal duct seams. However in my region we are mandated by code to apply it to the external ducts seams as well to prevent the tape from coming off (which does happen in our climate in very hot attics). I no longer use mastic on pipe seams because I have replaced this with "Hardcast 1402 mastic tape". This tape is considered to be a replacement and is much easier to work with, I also feel it forms a very good seal.

[@LeeFLE]

@@aglmechanicaltips thanks for the quick response

[@zackcall9024]

Where u buy the insulation at???

[@aglmechanicaltips]

I don't know if anywhere other than a local HVAC distributer.

[@UGotTheFunk]

​@@aglmechanicaltips Only stuff I've been able to find is Menards: R-6.9 Duct Wrap FSK Faced Fiberglass Insulation Roll 2" x 24" x 15' 30 SF - $22 Home Depot: Master Flow 60 sq. ft. R-6 Insulated Duct Wrap - $80
