- Hey guys I want to show you guys how we Insulate our post-frame buildings or pole barns which ever you want to call it.
.
Now I like to use 3" white vinyl backed fiberglass insulation. In my opinion this is one of the best options we have to Insulate these buildings with that is going to actually have an R-vaule and do its job.
.
Yes I know their is better, like spray foam but with the counties around me they won't allow spray foam unless you sheet rock the whole building or fire retarded paint it and both options are very expensive so we don't do spray foam much unless it's a barndominium or shouse.
.
I hope you guys find it informative and useful. If you have any questions just drop a comment below and I'll be happy to answer. Thanks for watching
Nice video, nice job! Is it necessary to use foam boards first and then batting or will it be just fine with batting. Thanks! Ceiling is blow in, I chose to insulate myself. Hopefully I didn’t make the wrong decision.
Thanks for the info! I got a question on a renovation of sorts. Got a pole barn with galvanized corrugate for the roof, trying to insulate it so I can have a humidity/ temp regulated shop where my big mill and lathe don't sweat. Is vinyl back insulation a good option even with the possibility of a leaky roof? Also, have any insight on how I could blend an insulated roof to an uninsulated roof (only a small portion of the barn is gettin reno'd for my shop), my understanding is you screw throught the metal roof/ insulation vinyl side down, into the purlins so the insulated roof sits higher than the rest of the roof. Thanks!
I have an existing building with this type of insulation in it. I am thinking about finishing the inside into an apartment with heating and air. I would be sheetrocking the walls also. Would it hurt anything to add more insulation between the existing insulation and the sheetrock? I want to frame up a wall even with the posts on the inside of the building. This would create an air gap in the wall if I do not add some type of insulation.
In my opinion this is the best stuff for finishing the inside. This type of insulation has the vinyl backing on it, that's your vapor barrier, air barrier. With that on there you will not have any moisture problems in the wall cavity at all, now do not do an inside vapor barrier because you all ready have one on the outside. So you want to use no faced fiberglass or mineral wool just do not us anything with a craft face on it or add plastic sheeting, a double vapor barrier will cause moisture problems.
@@kevingreenhaw8205 Its really not an effective vapor barrier unless the seams are totally taped.
@@michaeldoherty2289 yes it is a vapor barrier, no its not 100% seal but I can promise 95% is and that's a lot more than just metal wall with nothing and according to the manufactures it is a vapor with a 6" seam lap. So if this is considered a vapor barrier you do not want to do an interior vapor barrier or you will trap the moisture in the wall and cause problems,
Where the insulation crosses the girts, it is compressed and has no insulation value at all. Its really just a condensation blanket and not really meant to provide a lot of insulation value, especially in living areas like you described in this video.
Your right but I never said this is the only thing you want to do for the insulation on your home. All though lots of red iron homes us this and that's it or hundreds of commercial buildings you go into. But in my opinion this is ideal insulation for a barndominium home before insulating it with something else instead of just using house wrap.
