3 Reasons You Need To Use House Wrap

[@RattieRae]

Thank you SO MUCH for not only making this info available, but easy to understand. I'm disabled & I don't have a ton of money or a very big circle, so knowing how to do stuff on my own is A HUGE DEAL. Thank you for making this info accessible. 🥺🙏💖

[@deannasparks996]

Agreed. I spend my days lately watching your videos…I love them. And it reminds me of being a little girl and just sitting and watching my Dad doing this kind of stuff to our houses. Good times. Although, I am your age Jeff.

[@randysmith9636]

When I was building homes wrapping was a step we never missed. When we built my mom's house 30 years ago we used a combination of wrapping and taping every sq in of the home, 2×6 exterior walls, batt, spray and ridgid board. The best windows available at that time, a truck load of caulking, silent floor system, etc. It was built to a super insulated home spec. Which created some other issues to address. Air quality and moisture being the two biggest. I swear you can heat it with a candle and cool it with a cup of ice. Air exchanger with the air to air system, not sure how all of that worked but we had to bring in fresh air and vent moisture. It's 30 yo and still tight as a drum. When the HVAC system went out a few years ago it was a eye opener at the cost to replace and upgrade. Thanks for another great video brother.

[@cerealkilla4eva]

Very interesting. How did you address the moisture and air quality issues?

[@randysmith9636]

@@cerealkilla4eva As I mentioned, the HVAC system used a air exchange filtering system using outside air. Basically it exchanges stale indoor with fresh outside air. I know it has a Dehumidifier built into the system and I could be wrong but I'm thinking it has the ability to also add humidity for winter time dry air.

I ONCE GAVE some ultralight hikers a ride to the start of a 250km hike, and as a gift, they gave me a sheet of Tyvek and told me it makes a great groundsheet under your tent, to keep it dry. They were right - plus it's durable as hell and light as anything.

[@koryleach9660]

When we had our home resided two years ago we had them use the Tyvek wrinkle wrap. It creates drainage channels behind the siding. We resided with James Hardie plank, so we didn’t want the potential for the boards to hold any water behind them. The contractor used a weaved nylon wrap as standard that is neither air nor waterproof. So it was worth it to me to pay the premium for the upgraded product.

[@noahpelletier2510]

Starting on year 2 of total exterior renovation. Didn’t get the siding on last year so I have spent the whole winter with Tyvek on my house. Use cap nails if you are in a windy area! Still left to finish: replace half the windows, finish second half of roof, soffit, fascia, add foam insulation, move electrical meter, cap windows and doors, then siding … it’s a lot of work, but hoping I can finish by the fall of 2023.

[@knoxlowe1]

DIY tip: If you have some left over Tyvek, save it for the next time you go camping. It makes a fantastic ground cover below your tent. Ditto if you are backpacking and it's very light to carry.

[@baxt1412]

Is it a pretty close to one time use product for an under tent tarp?

[@HomeRenoVisionDIY]

Good tip!

[@psdeas7530]

ZIP sheathing provides the same protection as OSB+Tyvek. One step, instead of multiple product costs, steps+labor costs. Also, easier to tape off and eliminate tiny holes in the ZIP, as opposed to Tyvek.

[@andreycham4797]

Zip sheathing is made of osb . Osb is vapor retarded material. Who would want to put it on outside of a wall in a cold climate? Not Canadians that for sure

[@baxt1412]

Much more expensive though in almost every situation because the labor to put on tyvek isn’t a huge amount of time for a skilled group. But it’s also better as long as the people know how to hang it, tape the seams, and seal the fastener penetrations for the bottom 3 ft or so

[@mabolzichjjl]

If you're replacing the sheathing, sure. Zip is the way to go. If you don't have to then a house wrap is next best and more cost effective

[@georgejohnson3654]

ZIP is not the answer for everything. It's osb for one, not as permeable as most house wrap, and there isn't a positive overlap so you are completely relying on the tape and those installing it...

[@YellowBunchofBananas]

@@jasonfitzgerald6334 Not saying you can't DIY it; my point was more that what you were asking about was masonry work and not carpentry like in most of Jeff's exterior videos. If you want to take it on, depending on the age of the house, I would do some research before getting started to make sure I chose the right materials etc.. The hard part with old brick houses is that some of the home centre mortar etc. isn't always the right stuff to use since mortar mixes have changed over the years to suit things like changes in brick.

I may need to redo house wrap and siding without being able to afford to replace windows. If I do that, will there be a way to later replace windows without damaging the relatively newer siding and house wrap, and will the house wrap then maintain its effectiveness?

Help. I'm purchasing a TuffShed and finishing it out as a tiny cottage in Phoenix, AZ. I asked the rep why he marked that I would not be insulating it. He said so I will receive the radiant barrier which will help keep the shed cooler. Otherwise, I'd only get house wrap. What are your thoughts? 🤷🏽

[@billsedutto8824]

Do you normally install it horizontally or vertically? How much does it effect the integrity of you cut smaller sheets as opposed to installing in the longest strips that you can? I had to do a small job covering a storage area under a second story deck that the previous owner didn’t finish. I did it horizontally starting from the bottom and wrapped three sides in one piece. I wasn’t sure how bad cutting it would be and it was relatively small job so I dealt with it but would have been a lot easier to do in in smaller pieces especially when the breeze kicked up.

[@JimYeats]

Its typically done horizontally, starting from the bottom - as you did - so that it overlaps. Always try and keep the pieces as complete as possible. Less seams.

[@charleshoughton]

Is there any benefit to peel and stick house wrap? Is a vapor barrier like Matt Risinger uses, a bad idea for older houses? (1950s house with asbestos tile)

[@koryleach9660]

That depends upon your climate. In the south you can have a vapor closed system on the exterior of the house. In the north you cannot. The vapor closed system goes on the “warm side”. To keep any condensation in an area where it can dry to the warm area. I.E. I live in Minnesota, we use a vapor barrier on the inside since over 50% of the year we heat the house. Any condensation would hit right behind the drywall and can dry “in” in the south a primary cooling zone that condensation potential is kept to the other side of a wall so it needs to dry to the outside. The main “benefit” is no need to tape the overlapping joints of the wrap as the adhesive does that job. The downside, cost!

[@charleshoughton]

Almost 20 years ago when I built on to this house I used 30 pound roofing felt and 6 mil plastic. Felt over the plywood then plastic over that. Wish I'd know about Tyvek back then. It's sealed up but I have mold that forms on the outside vinyl. I think that's why. Inside it's fine. I have plenty of air flow with the HVAC unit and don't have an issue indoors. But, that vinyl siding molds constantly now. At least no water will penetrate into the plywood and walls. Just no air goes back out now.

Jeff, I’m looking at redoing my siding this summer. 1970’s construction in the Appalachians.

I want a continuous envelope on my walls due to 2x4 framing and our frequency to drop in the 10-20*F territory in the winter. Any recommendations on exterior insulation + house wrap assemblies?

My house is 100 years old - you can see the wind blow the curtains inside. I've been thinking of stripping the shingles and then using the zip system over the random board sheathing that's under the shingles (i'm not sure that tyvek would be enough with all the gaps). or would it be better to just put up normal osb and then wrap it?

[@damianrico2433]

Great Video, thank you sir!!

What about if the Tyvek is ripped and stapled back together? The new $650k house up the hill sat for months last winter without siding and the tyvek got ripped to shreds by the wind. They didn't rewrap it, just stapled the flaps down.

[@vornamenachname8783]

crazy 😎. We just visited the US and were highly curious, why you wrap your houses - outside!!! It is the complete opposite philosophy of what we do around here 😅. For the common understanding, people say that the "breathable" vapor barrier must be as close to the inside as possible to avoid humidity to reach the dew point. High diffusion resistance at the inner side, low resistance at the outer side. As you do it, it is absolutely quick and cheap. For sure, the most important thing is to avoid convection. To do it from the inside is the better way according to physics but it is a massive effort and extremely sensitive to damage. They put air pressure into the building and measure the loss over time. If it is too much, some people have a lot of work to make it air tight afterwards. Find the whole in the wall... . I am afraid, many of the new houses will not last long and have extremely expensive repair costs. The first plumber or electrician to change something will destroy the air barrier and if he doesn`t make it air tight again - what happens - you have a house that is damaged in the construction after plenty years. We can heat a new house in Germany for 300-600€ per year. But it costs at least twice of what you pay in the US. Although Energy is so much more expensive here, the high costs for super duper insulation will hardly ever pay off. But that is due to green politics, so only upper class people can afford a new house meanwhile.

[@dslay04]

thoughts on Zip Sheathing?

[@laloajuria4678]

zip would be the much better long term choice.

[@mattb9664]

House wrap over osb is bare minimum. Zip with the barrier integrated would be the next level. Foam board over osb would be the better than zip but needs more time to install. All need taping at all seams for proper seal.

Could anyone confirm if this could be done with stucco ?

[@JimYeats]

Sure, but you will need to put up something that the stucco can stick to and support its weight. Metal lath is the most common. In many area’s you see stucco homes built with EPS foam used as the WRB with the lath on top of that and then the stucco. Edit: I believe that asphalt impregnated paper (kind of like what you see on your roof) is the most common WRB with stucco because it seals around all the lath penetrations better when it gets damp.

[@denisegaylord382]

It needs to be behind the stucco. I believe when they stucco they build a gap between it and the actual exterior sheet good, so water (vapor) can escape, and not rot the obs/plywood that they attach the lath too.

[@kenjackson5938]

Hi Jeff, "house wrap" is cheap, but the Perfect wrap is Not Typar or Tyvek, because as you have shown, it Holds water. All the latest building science, not opinion, has well shown, a water vapor permeable membrane is the correct product. These are designed to let water vapor from the inside of your house to pass through to the exterior, but not let water from the exterior get in. Yes, they are a One way vapor directional barrier, and definitely more expensive, but they will not allow moisture to condensate in your walls. Building science has also shown, 6mil poly is another terrible product, because it also does not allow your house to breathe. With new codes pushing for more insulation, and wanting to have houses tighter and tighter, the mold and complaints of bad internal air is Not because the houses are too tight, it is because the air is trapped. The proper membranes allow it to breathe in a correct and controlled manor. If you are going to use typar or tyvek, then, my "opinion" would be to overlap joints by more than 4", maybe 12", and not tape the overlap but staple. This "might allow moisture or vapor that is inside the walls to exit, but greatly reduce air flow. Again, the last part about the overlapping joints is my "opinion, but the other is the recent and current science. Regards,

[@rozinant1237]

R-value is the measure of a materials thermal resistance. Insulations, both rigid and batt have known R-values, OSB even has a small amount, but Air-Barrier’s have zero. You are correct when you say air barriers can help reduce heat loss, but they accomplish this by spanning and covering gaps in the framing and sheathing. These holes would be a source of heated air leaving your building, drafts if you will. To be clear, Tyvek does not ´add R-value ‘

[@rozinant1237]

@James Karrie Which is exactly what I said. A hole is leaking air, the Tyvek blocks the hole, therefore you lose no heat due to leakage. We do not measure this loss of heat in "R-values"
