I am hoping to install windows and doors this weekend, and need some advice or a quick and dirty how to lesson. I was planning on tar paper about 9 inches wide, starting with the bottom then the sides then the top of each rough opening. Then putting in a foam and adhesive sealer (not sure the techinical term) and then nailing the flanges to the osb and studs.

Can anyone tell me if I am on the right track by morning? any other tips or advice? I have not done this before...

They use a butyl type wide tape now. T here is even plastic inserts for the corners. Check on youtube for window installations for new construction. Look at many, they do it somewhat different from installer to installer, but lots of similarities. From the sounds of it, you have the right idea.

Here's a graphic that shows the basics

http://inspectapedia.com/BestPractices/Figure3-13.jpg

Basic idea is to apply all layers in shingle fashion, where progressively higher layers overlap lower layers, so that water dripping down is always directed away from inside the house wrap. Don't rely on caulking or other sealants unless you have to- if it is all shingled to shed away they are not necessary. Caulk will eventually crack and leak, flashing stays and sheds the water away.

Hope this helps

Tuck under the bottom fin, run over the sides and onto the housewrap, run over the top fin but tucked under the housewrap over the top. Think like a raindrop running down the wall, never invite it in.

To put in windows
This is better with a person inside to lift the window,Another outside to nail.Its hard to do both and get it right.It can be done with one person.I have.
Put a screw or nail in the high corner.Raise the other corner to level.Shim shingles to hold that are a good idea.A flat bar under the window raises it.Then make sure the sides are plumb.Fasten that.Screws are better if you make a mistake.
Before you put the window in-
I use Ice and water shield strips.Start with One across the bottom.Then two up the sides. Then one across the top of the opening.About 6 inches wide depending on trim width.That goes over your TYPAR type stuff you wrap the building with.Before you install the window.You can silicone the back of the window trim too.That gets messy.
Try your window.If it binds,something is wrong.
WRap your building over window openings.Take a utility knife in the corner of the opening and make an X.Pull the excess into the house and staple it,Cut off the extra.
after the window is in
Foam the gaps between window and framing.Use the less expansive foam only fill the gap halfway.It keeps expanding.
I expect you to hang all doors and install all windows before lunch.I will be inspecting.

Just to be clear, Mainiac said "less expansive" not "less expensive"

As well, Mainiac might be Manic, but his mania might just be a Maine idea (in the main). That's the more expansive, least expensive, explanation. Worth 2 cents.

AS it happens the less expansive is the least expensive.
Trust me.If you overfill the gaps the stuff is like that old movie ,The BLOB.It will engulf the building
It comes out in lots of odd places.

ALSO try to center your window in your Rough opening.You have to shim it and if it crowds one side,you cant.Also the tiny gap is tough to fill.
Make your RO about an inch or so bigger.Two inches is OK too.You can fill that if its too big.If your framing is askew,the window can be plumbed easier in a bigger opening.
Try to get someone to help u .Someone to hold the window inside and level as you give directions.
UPstairs widows are passed out the opening.Dont bring them up the ladder.
Its hard to give directions since this is all second nature to me.
I just put in 3 windows and 3 exterior doors alone.Much swearing was involved.

Doors are pretty similar.
start by centering ,hecking the sill for level.Shim if not.Some have adjustable thresh holds?
Work the hinge side
.Shim the top hinge .Take out the top hinge screw.Replace and screw home with a larger screw that gets thru the shims and framing.A couple of big screws thru the hinges and into the framing are a good idea.The top hinge is the key one.
Eyeball the hinges below and shim and screw it plumb.
Do the latch area next. and then that side.
Check to see how it shuts.Check the gaps around the door.Supposed to be the same.
GAPOSIS may result.
If You have trim on, Tear off the brick mold and replace with flat boards.That BM is crapola.Glued up CRAPOLA.
You be the judge.

Thanks again for all the help! I did have some help on Sunday getting them installed. I have pictures I will upload tonight. Its nice to have the shell completed, but there is always something... Now to get the deck on before winter stays around! We woke up to frost all weekend already and snow about a hour from our tar paper shack!
