- How to build a post & beam greenhouse. In this video I start work on making the roof rafters. I cut a pattern of the rafter shape and copied it on western red cedar 2x6 blanks. After cutting and staining these rafters they have a birds mouth notch cut and then they are installed on the roof between the North-South 6x6 beams and the 2x8 ridge beam. Then 2x4 and 2x6 blocking is added between the rafters to add stability to the roof structure. Then I begin cutting the twin wall clear UV protected polycarbonate panels and screw them to the wall studs with roofing screws. Then the glazing is cut and installed on the roof. A custom made ladder is used to lay over the roof to then add the ridge cap. We also make a door from cedar that will support two polycarbonate panels after it is installed in the next episode. This is the third instalment of the detailed greenhouse build series. I have a 14 page greenhouse plan that's available at the link below.

Before I build anything, I watch a lot of videos to see people's ideas and to come up with some of my own, This video was extremely helpful. And you did an absolutely beautiful job
I came here to see the polycarbonate and stayed because damn that is a mighty fine looking building. Absolutely beautiful.
This is true contemporary artistry
As an experienced builder looking for good tips on installing twin-wall polycarbonate panels, I found this video nothing short of excellent. An added bonus was seeing your design and woodworkmanship. Your home-grown cedar is, wow!, a very primo building material! Nice!
I'm liking the pace of the release of the detailed vids of this project. Thank you for not making us wait a week for each new installment.
Thanks!
That is one classy greenhouse. Just finished my 3rd polycarbonate greenhouse for growing Orchids, about 10 years ago. That is the toughest material man made. We had an f-1 tornado took 6 panels off out of 12, found all but 1 scattered about a mile through the woods behind the house, all reusable mostly. Has never yellowed and and you can walk on it between the roof trusses. Wont burn, and you can cut very easily with common saws.
Thanks for all the tips! I am about to start the rafters on my greenhouse and seeing your process has come in handy!
I'm still in planning mode, but this video helped reconcile a lot of the problems I was running into on paper. Thank you for the in depth commentary
One of the best roofing tutorials I've ever seen. Great explanations and tips. Well-done!
Thanks 👍
amazing work!
Lovely problem solving addressing the ridge cap installation . And holes for the roofing screws on your ladder .. i can only aspire
Hope you two are already growing winter veggies in the greenhouse, if it's not too cold where you live.👍
I have some wiring, lighting, and shelves to make yet.
Amazing skill and clever craftsmanship. 10/10
This video is straight to the point with outstanding visual aid. THANK YOU. Being an extremely fast learner, the majority of videos on CZcams for something like this are extremely annoying and full of nonsense. You've earned a subscription from me, sir. 🙏
ONE OF THE MOST OUTSTANDING TUTORIALS !!!!!!!
Thank you for this video. It is by far the best on working with polycarbonate roofing I have found so far. You mention a lot of details and, things to be aware of, that others don't.
Thanks!!
So many smart tips and ideas! Really interesting to watch and can't wait for next video! 😃
Wow, that looks really beautiful. Your explanations and style are very clear and easy to follow. Can't wait to see it finished.
Thank you so much!
I learned from another CZcamsr (Justin Depew) that made a dust collection system with polycarbonate that silicon doesn't adhere to polycarbonate very well, he found a product called Sik-A-Sil which looks and acts like silicon designed for polycarbonate and it did the job.
So far I haven't had opportunity to try this product/material myself, but I have kept it close to the front of my mind, and have let others kw about it in the meanwhile. Great work on that very classy greenhouse! I am envious!👍🤙
Thank you very much! And thanks for the tip!
Beautiful work and processes. Your videos have become the gold standard in my book. I really appreciate your thoroughness and clarity while showing and demonstrating your work methods.
Wow, thank you!
Thanks for saving me time by explaining to do the ridge cap in sections. I also laughed when your wife mentioned 911, I think it's in their DNA as mine does the same thing lol! Green house looks great!
Great craftsmanship and attention to detail. One thing I’ve learned is to have a table or stand near my work area to place my tools. Saves having to bend over every time I need to grab the circ saw or jig saw off the ground. Especially handy when doing a lot of switching back and forth when cutting rafters.

VERY helpful! I’m just starting my greenhouse after a move- thanks for your great ideas.
Amazing work. ❤️ Thank you for sharing. 🙏
Amazing build. I’m about to install panels this weekend and you have some helpful tips (like not letting the metal ridge cap touch the plastic). 👍👍🇺🇸
Really incredible build and video series. Thank you for putting this together
Glad you enjoyed it! Thanks!!
That was wonderful to watch!
Thanks for the great video! We too ran into the exact same problem when installing the roof ridge cap. Your idea will certainly help!
Awesome, thank you!
This has been so helpful! I have polycarbonate panels for my greenhouse but I didn’t know about the H joints to fill the gap between them, and I hadn’t thought about expansion.
Your greenhouse looks super nice!
I’ll need something a little more insulated for my USDA zone, so I’m working on a passive solar design.
that came together really well.
a yankee gutter to catch rain water would would've been a cool addition
I might have to look into gutters in the future.
this is an absolutely great job what U did sir :) thank you for sharing this
Thanks! I’ve been looking for this exact video. I’ve been trying to figure out how to install biwall on a lean to greenhouse and I think your treatment of that answers my question.
Excellent! Thanks!
@manabouttoolsmessagenicegrampr nice gram?
Very nicely done.
Очень аккуратная и красивая работа! Спасибо!
dude this is beautiful
Nice job 👍
So good!
Looking good. 👍
Thank you! Cheers!
AMAZING!
I just found your channel, and I'm loving it! I just subscribed. Your greenhouse is beautiful!!!
Thanks!!

Great job 👏 👍 👌
Thank you 👍
Excellent.
Thank you! Cheers!
Wow!
Hey I am enjoying watching your videos about this green house so much!
I wonder if this type of framing is suitable for a tiny home, I wonder how you would insulate a structure like this best. The only downside is, how to do so without enclosing the framing. I would want it exposed on the interior like traditional timber frames
I would love to see you Build an octagonal frame cabin with this style framing! I would buy those plans!
outstanding !
Thanks!
@@MANaboutTOOLS No sir TY, Merry Christmas brother
I love ow she told you in no uncertain terms that if you take a dive 911 gets called before she helps pick you back up. 😅
That was very funny!! More-so because I work as a paramedic.
best looking greenhouse! do you have a link for the H channel and J channel? or did you buy them local from home depot?
Enjoyed your greenhouse build series! Would like to purchase the same polycarbonate panels but the link only takes me to the Amazon page and I can’t find your panels, also what was your resource for the “H” & “J”(I believe were the names ) guides that you slide the panels into?
Thank you,
Walt
I'm building a greenhouse as well. I ended up buying twin wall polycarbonate sheets that are 2 ft by 8 ft long. I was planning on framing the greenhouse with studs 24-in on center. The installation instructions for the panels say not to drill within one and a half inches of the edges. This doesn't leave much room where two panels would connect on the stud. Do you have any idea on how to install these panels? I was thinking h connectors and then screw the h connectors into the studs. Thank you for your videos.
Hey there....just bought the plans for this green house. Do you by chance have a link where I could get all the glazing panels? Thanks!
💛
How do you do birdsmouth. Any videos out there for calculation etc?
and you send me your video on how to calculate and creat curved inside corner braces please.... great videos by the way. clear and precise ☝
Thanks! See: czcams.com/video/MriXh3ceQco/video.html
Great detail! I like the looks of the timber frame construction and would like to utilize this design for repurposed old farmhouse windows instead of polycarbonate on the walls. My question has to do with all of the wall studs, are they necessary for structural integrity since you're utilizing the larger timber frame construction? I would like to omit approximately 50% of them, putting them on 32" centers to accommodate my farmhouse windows. Do you believe there would be any issue doing that?
The studs do add some support to the 6x6 beams but, I think your spacing would be okay.
Will the 6mm panels hold up as good as the 8mm mostly obviously 8mm thicker and stronger but it’s difficult to find 8mm in a certain size
Thanks for your video! It is inspiring! A question: Should the UV side of polycarbonate sheet face outwards on inwards?
Should face outwards
Quick question. If your roof is long in my case 17 feet how would you connect to plexiglass panels vertically.
was it necessary to use metal and wood for the ridge cap? Why not just use metal only?
When I saw your greenhouse build, I knew it was the one my wife and I wanted to build. We are super excited, and this morning I downloaded the plans and cut sheet. It is possible, I have not yet found the dimensional cut sheet for the polycarbonate glazing. If there is one, please direct me to its location. We are planning on upscaling the plan, perhaps to 10x24, or 12 x 20, depending on the roof glazing dimension. In the videos, it appeared you were cutting both length and width for the roof. If the roof panels are a full 8' long, we would have to just extend the length of the greenhouse, whereas if they were cut, we could extend the width, too. Please advise, and thanks for putting together such a quality video series and greenhouse plan.
Thank you so much for your support. I don't have a polycarbonate sheet cut list. I think it might be better to take a measurement and cut each sheet as you go along. Also, with my rafter spacing, I had to trim a bit off each sheet lengthwise to allow for the gap required for the H channel. If I was going to do this again I would space my rafters a bit further apart so I would not need to do this. But, that also can mess up the design and the standards for spacing we are all used to. So... just keep that in mind. I don't know what is really the best way to handle that. Cheers, Kent
@@MANaboutTOOLS ok, thanks for the reply, Kent. Do you have a link for the twin face polycarbonate panels? I saw them on Amazon for about $169/sheet, but found a vender as low as $99/sheet elsewhere. I just want the UV secure ones like you used. Thanks again!
What thickness is the polycarbonate sheets you used?
I would think you would have to leave the bottom and top open to let condensation to drain out of the vertical wall sheets?
There's J channel on the top and bottom if the sheets. I drilled holes in the bottom channel so condensation could drain. Wasps will make a home in the channels if not covered.
I heard polycarbonate reacts badly to UV light. Is that true?
I saw a comment where someone asked about the polycarbonate but with there being so many version and sizes can you recommend some specifics on the polycarbonate, I.E, what millimeter size, does yours have a hollow channels/combs? there's a glaze on yours too, did you chose a glazing with a certain amount of UV or sunlight protection? There's so many online choices for this stuff and very few if none available in local stores to put your hands on. Any details are appreciated, its a great project.
I used the 8mm (5/16) clear twinwall with UV protection on one side. I bought 20 sheets that were 4' x 8' in size.
@@MANaboutTOOLS Awesome build…. Was wondering does the UV protection interfere at all with sunlight needs of the plants?
Where did you purchase panels?
Why the gap between the ridge-cap and the polycarbonate? Why must the galvanized steel not touch the PC?
I was told the sun can heat the metal cap and possible damage the polycarbonate glazing. So I made the wood cap to separate them.
@@MANaboutTOOLS is there not a polycarbonate ridge cap available?
Where did you get the polycarbonate sheets and accessory materials? I was looking at a few places and they are a bit pricey.
Maybe do a search for greenhouse plastic in your area. Plastic prices are volatile like lumber prices.
If I may ask sir, what type of screw did you use for the pannels and at what distance apart for the roof? Ty
I have most of the hardware listed here: manabouttools.com/post-beam-greenhouse/
And I think I had screws spaced every 24"
How long did it take you to assemble the building after the concrete was ready?
Total video shooting days was 27 (including foundation build and pour). Many of those were half days. If that helps.
@@MANaboutTOOLS Thank you!
16:34 "You don't want metal right against the plastic poly carbonate plastic panels in the sun". Why is that? Too different dilatation under high temperatures?
Is there any water leakage at the h channel joints?
I have not seen any.
16 inch centres on the walls is overkill, 24 inch centres would do.
Probably but, the shelves in Part 5 have more attachment points.
What is the size of your polycarbonate panels?
Mine were 4'x8'
@@MANaboutTOOLSThank you for sharing. I love all your projects but I have to say that the greenhouse is my favorite💜💜💜
sorry I missed the Dimensions
dimension please
The base is 10 feet by 12 feet
oops. why don't you want polycarbonate touching metal? I've got this stuff on an all steel structure 😬
This was a recommendation from my supplier. I guess the idea is that metal, being a conductor, would heat up to possibly damaging temperatures on a very hot, sunny day. And, the metal ridge cap (in my case) is a large surface area and would be lying on top of the polycarbonate.
With this house, I finally became the owner of the house I always wanted to be in. The hospital elite package has 2 bonuses; the first is about the base and the roof, czcams.com/users/postUgkxS-P9OAq3v4HNpPFqYFWNEq9A-E_PbZIN the second is about the confidential staff who give advice and the advice that worked for me. Thank you very much
