We do use foam guns but I do think gaskets are the best as foam can get pretty rigid. (Trick with the foam gun is to Vaseline the can to gun connection and after using very tightly close up the adjustment knob and never touch it with cleaner and then make sure it gets used once a month at least). <u></u><u></u></span></p>

We are securing windows and doors to the outside foam skin using taped flanges (adding flanges to wood windows). Tied back to framing with strapping. Leaves a flexible assembly. If it is a wood window with wood liner – the liners are made up as part of the window (biscuit) and float with the window in the opening.<u></u><u></u></span></p>

<div><p class="MsoNormal">I've heard about but never tried Tremco expanding foam tape. It comes off the roll very thin, and sloowwwly expands. You apply it to the window perimeter, and you have a few moments to slam the window in place, and level and square it up, before the Tremco swells to seal the gap. If you run into a problem with the opening, or have to stop and take a leak, the foam expands larger than the opening, and you have to scrape it off (at what, a buck a foot???) and start over. <u></u><u></u></p>

My method has evolved into stuffing the appropriate diameter backer rod from the outside and from the inside around the perimeter of the window. Done carefully I convince myself that I'm creating some dead air space in between the two foam layers. <br>
Are there better ways of doing this? <br>I am aware of and used to use a foam gun. But I never can seem to make sure to clean the gun when I'm done and so the next time I have to buy the expensive acetone cleaner and take the damn thing apart again. Which is one of the reasons I've switched to backer rod. <u></u><u></u></p>
