I have seen many homes lately with the windows being flashed with Typar or Tyvek.I’m not crazy about the idea. I’ve replaced five year old trim where this was done (water damage). I’ve always used felt and caulked the back of the flanges before installing the window. I’ve also used Ice and Water shield instead of felt which I like even better other than the cost. Wondered what other’s thoughts were on this? Thanks!

I have been using Tyvek tape to seal flanged windows to housewrap.
Proceedure: Wrap housewrap into rough opening. Caulk back of window flange. Nail (or screw) window in place. Use Tyvek tape to seal flange to housewrap.
The Tyvek tape will stick to just about anything, including tar paper. I'll let you know how well this methods works in about 20 years or so, but it sure beats most other methods I've seen. It is also fast.
I have also seen aluminum duct tape used the same way. There are some self stick flashing tapes available, but I can't get them locally. I bet they are costly.

Bought some of the flashing tape as shown in FHB. Haven't used it yet, but probably soon. Also have seen the water and ice in an ABC cagalogue - probably would go that way if I were to buy over again. My current project had aluminum flashing over drip edges. Worke well for 35 years. Oh, yes, had 30# felt for house wrap also. Going to stick with this, thoug have used tyvek before.
Just a little slow on my projects as the years go by.

Repeat after me...my new mantra is....
Bituthane...[spelling]..?? Bitchethane...
Sheet metal pans...in wood windows...where applicable....Copper if the client can afford them....turn pans up either side jamb...and inside turn up also...run bituthane into pan upturn...
Sheet metal pans...in sliders....and....french doors...legs turned up...and out...bitchethane on sides and head...
You will never go wrong...no drips..no runs...no errors....
Worth every penny invested...when the wind be howlin..and the rain be blowin...it be holdin....and..you be sleepin...like a baybe...

I'm game. What is Bitchethane? Yeah, when the architect designed my office remodel, lots of pans.

Bituthane...is a waterproofing material used for foundation membranes...It is sold..in 12 inch and nine inch rolls...sticky as hell...a bit difficult to handle, but worth the effort...flashed just as any window...sill first...side legs second..window in...top on over top flange...
Must make sure caulking is compatible with flashing...Rumour has it...that Sikaflex and Bituthane...are not compatible...
Dandy stuff...Fire and Ice works well also..a little easier to handle....

Ah, saw the water and ice in my ABC catalogue. I will probably try that when I use up the stuff I ordered for the windows I have yet to get to. It was in an earlier issue of FHB. Basically a sticky tar paper of some sort.

I installed 18 new Marvins last summer to a beach house. Used the peel and stick method, Bitchethane
6"wide roll 100' for $27.50. Worked like a charm in the winter winds
*Thanks! Sounds like pay now or pay later ..... it's always the little details that kill you. I've been setting my siding (cedar shingles, pine clapboards) in a bed of polyurethane caulk where the siding butts the window ...... do you folks think it's a good idea?

I think the "rubberized asphalt" stuff is bituminous -- bitumen is pronounced bitch-men, maybe that where these names are coming from?
Spelling/source on bitchethane?
