The windows and doors arrived today. Overall they look great. Yaro sent two people to uncrate and help unload them, and then to install one window for instructional purposes. Dave and crew took advantage of the extra hands to get the big window into the house and installed in the rough opening.
For the technical details refer back to the post Windows and Doors.

with my windows to a port somewhere in Europe.

|October 8, the container arrives in my driveway|
|The windows are screwed directly to the bracing.|
It took about 30 minutes just to extricate the windows
before we could start unloading.
|The big window in the house and waiting to be|
installed. Those black round things are the suction
grips that make it a lot easier to manage these
quite heavy windows.

|The trim is actually dark but is covered with a|
white protective tape.
|U-factor 0.13 = R-value of 7.7|
COG stands for center of glass so the glass itself has
an R-value of 11.3. The overall R-value of the window
is reduced because the R-value of the wood frame is
probably closer to 4 or 5.

It looks like you used Grace for sill and what else did you do? Is there some back dam of sorts so water doesn't get inside? I like the idea of bringing the window all the way in like yours (mine are Zola I'm about to install) mostly because I realized if it sits in the middle or an outie, then you cannot lay the sash back against the wall. You end up with a window sash jutting into the room which is a little awkward. The problem is my carptenter about had a heart attack (he needed to be calmed down) when I suggested bringing the window further in the RO. He is/was convinced everything would leak and then rot. I have a similar set up as you as far as the 'layers' of the exterior. What's funny is I could only find the polyiso with the felt facing at the local roofing supply place and not the foil faced. My contractor said the felt is much more forgiving and doesn't rip and tear like the foil faced does.ReplyDelete
Not sure I quite know the answer to your question but here's how I think the windows were finished. Besides the Grace Ice and Water Shield for the sill, it looks like they taped the edges and the top of the window to the Zip board sheathing. Then the polyiso over that but with some 2x4's around the edges to attach the trim to. Then they built the trim box (the extension jambs and the trim) in one piece and and installed it in the opening of the foam, attaching it to the aforementioned 2x4's. The trim box is constructed from Boral TruExterior trim which is a fly-ash based composite. Since it has no organic components it will never rot. The exterior of the windows are painted aluminum so they should be pretty rot-resistant as well.ReplyDelete
