Acceptable install of windows and housewrap?
Hi everyone –
We installed new Andersen 400 Series windows and Tyvek WRB on our house currently under construction in NJ.
Can anyone knowledgeable please comment on whether this is an acceptable installation, or if we really should redo everything?
I am prepared to redo, but given the cost I would like to be certain that it’s really necessary.
I recently posted here about the same issue, but I thought I would add some detail here and expand the discussion to include the Tyvek install. A link to the original thread is below.
As you can see in the photo here, many of the manufacturer’s installation instructions have not been followed. Some things I notice are:
+ No caulking used at all on windows
+ No proper flashing tape used on sides or top of windows, just Tyvek housewrap tape
+ It looks like they lined the rough openings with Tyvek and a bit of Vycor Plus flashing at the bottom only, then installed the windows without caulk, then installed a layer of Tyvek across the tops of the windows, and over the top nailing flange, then taped the flanges with Tyvek housewrap tape
+ They taped across the bottom nailing flange with housewrap tape
+ They did not overlap the Tyvek by at least 6″ as required in the instructions
Thank you in advance for any help!!!
