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!

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!

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.

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.

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.

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!

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
@aglmechanicaltips Год назад
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
@Axel-xs3fj Год назад
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.

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

Can you clarify the insulation thickness? Are you referring to the out of package thickness or the installed thickness?
@aglmechanicaltips
@aglmechanicaltips Год назад
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.

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
@aglmechanicaltips 3 месяца назад
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.

What’s the difference with applying mastic to the duct seams before insulating vs the insulation itself?
@aglmechanicaltips
@aglmechanicaltips Год назад
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.
