Installing Tyvek Weather Barrier House Wrap: How To Build A Shed ep 12

Sharing buttons:


in this video I'm gonna show you how I

installed a vapor barrier all around my

shed now some folks call these air

barriers or moisture barriers it's just

a barrier that keeps water from getting

in as well as keeping air from getting

in from strong winds but it allows the

structure to breathe I'm using the

product from DuPont called Tyvek I

bought this and paid for it myself I'm

not sponsored in any way this just

happened to be the right size for what I

needed at my local Home Depot I think

this roll was about three feet or so

tall and it came with more than enough

length on it to do the entire shed for

fastening it I decided to use the same

nails I was going to use for the roofing

felt a lot of people prefer to use

staples when attaching this I went with

these nails because I wouldn't have to

put in quite as many and I already add

them so we're going with these before I

got started with the wrap I needed to

cut out the threshold on the gable ends

and you may have seen in my previous

video about framing these gable ends

that I did a little trick when I built

these walls in the first place before I

stood up these walls I cut halfway

through them from the underside which

was gonna make it really easy to cut

through from the top after it was all

stood up and I was at the stage it was

time to cut out the threshold and I did

this because I didn't want the saw to

come down and scratch up my finish on my

concrete and dull my saw blade so that

made cutting this out really easy you

can see I only had to go about half way

through and then this threshold came

right out so with the threshold cut out

it was time to measure up and mark the

wall where I wanted the top of the wrap

to be installed and I wanted to make

sure that the wrap would overlap down

beyond the bottom of the wall by about

an inch so I marked it so that it would

do that so that any water that gets in

on the wrap would come down below the

wood and just come run down the concrete

foundation then I used my level to

transfer that mark all the way down the

wall and then just stretched out the

wrap and met it up with that marking and

nailed it in the process is really

pretty straightforward the the one thing

you want to do if you are gonna nail it

is you want to make sure you're hitting

studs with those nail

when I installed my sheathing I was

careful to make sure that the lines that

are already on the sheathing lined up

with the studs inside the walls and so

it was pretty easy because my walls were

already marked if if yours aren't that

way of course you can snap a chalk line

or mark them before you do it so then it

was just a matter of working my way all

the way around and installing the

sheathing just nailing it in about every

16 or so inches on every stud alright so

I finished with the lowest course of my

house wrap and now I'm ready to put it

on the next one the problem is I'm

working alone and trying to hold this

and unroll it and hold that up and wrap

it around and find things and hammer and

nail it there's just too much I don't

have enough hands so if you're working

alone I've got this neat trick I want to

show you that makes installing house

wrap really really easy and it involves

this painters pole and a clamp let me

show you this painters pole is one of

those extendable kinds you twist this

end and it gets longer if you happen to

have one of these laying around already

they're great for this if you don't you

could use a piece of PVC or even just a

broom handle anything that is gonna fit

inside the center roll of your wrap

slide that in like this now all you need

is to put a clamp right down here

that'll hold the wrap and approximately

the correct height and then you can roll

it out really easily and be able to nail

it in I'm just going to use one of these

quick clamps here so there you go it's

ready to start pulling out and this

clamp will be able to lean up against

the wall like this

and stay there while I'm busy nailing

things in once I'm finished with this

course the reason I really like these

extendable poles is because then to do

the next height all I have to do is lift

the pole up and extend this end lock it

down and now you're ready to do your top

course or your third course so let me

show you how easy it is to use this

thing so I'm going to measure down six

inches and I'm just gonna make a quick

little mark it doesn't have to be very

precise and I'm just gonna do this at

each of the corners all right so now

that I've got my Heights marked all I

need to do is adjust this clamp so that

the bottom of the wrap is more or less

right in line with that mark doesn't

have to be perfect

boy I'll tell you what having this

painter pole really really helped it was

almost like having another person there

to hold the wrap in about the right

place and as I worked my way down around

the walls it held up the wrap you know

close enough to the correct height that

it was really easy to stretch it and

pull it to exactly where it needed to be

and then it was just repeat the same

process I'd done on the first course at

the bottom and repeat that process all

the way up the wall

now I know that there are some of you

out there who are watching me install

this going why in the world is this guy

putting a vapor barrier on a shed well

the answer is because for now yes this

is just going to be a shed it's just

gonna store my stuff but at some point

in the future I might decide to turn it

into a workshop or into a man cave or to

some other functional kind of a building

where I might want to insulate the

interior walls run some power out to it

maybe install an air conditioner and at

that point it will be too late to put

any vapor barrier into the walls and

I'll really need it at that point

so I decided rather safe than sorry go

ahead and take the time and get that

installed now and then I don't have to

worry about it if I ever decide to use

this as something else all right so once

I had all of the walls wrapped it was

time to tape up the joints now DuPont

makes this specialized Tyvek tape that

matches really well with this wrap it

bonds very very tightly and it's stupid

expensive it was like 20 bucks a roll I

wasn't real thrilled about that but I

decided if I'm gonna do it I'm gonna do

it right so I went ahead and bought

tape now I did find that this tape

doesn't really like to unroll very well

at all so one trick I used that save me

a lot of frustration was when I was done

using the tape for a minute I would just

fold down one the end just a little bit

and that would give me a tab to pull on

later that made it really easy to start


the the next seam that I was going to

tape down so the only note that I have

for taping is to take your time and be

really careful because once this stuff

sticks it's like superglue it does not

want to come off and you want to try and

rub out any kind of creases or kind of

imperfections make it as smooth as you

possibly can

once I finished up the taping then I

just wanted to make sure the gable ends

were all covered up as well this is

mostly for driven rain ingress we do

occasionally get driven rain here and

driven rain for anyone who doesn't know

is rain that is blown hard enough that

it's basically raining sideways and so I

wanted to make sure that the gable ends

were recovered in case this you know

sighting had any cracks or leaks that

would let water in there's no real

tricks to this particular process just

hold it up there as best you can cut it

around the things that are already there

and nail it down around the edges and

then tape up all the seams when you're

completely finished so that was

basically it once I had all the seams

taped up then the shed is ready to start

installing trim and siding and that's

what I'm gonna cover in my next video

next video comes out and I hope you've

learned something if I did something

that was boneheaded completely wrong or

just plain stupid

by all means I'd love to hear about it

down in the comments I learned from you

hopefully more than you learned from me

so let me know if you find anything

there that I could improve on I'd sure

appreciate it

and as always thank you very much for
