What type of Foam should be used
What type of Foam should be used
A contractor is installing 11 Soft-Lite windows in my home this week. 4 of the windows are 102 units and the rest are a normal sized window.
What type of Low Expanding Foam should I tell him to purchase to ensure the windows are properly insulated?

Re: What type of Foam should be used
Why not let the contractor use what he normally uses? If he doesn't normally use foam, I'd let him do whatever he's comfortable with. I would not want my house used for him to learn to use foam.
Re: What type of Foam should be used
I agree with EcoStar, for the most part. However, if you've got a sharp installer who's looking to improve his installation technique, I'd consider being his first job with foam. The key is knowing that application should be done sparingly and slowly, until he gets the hang of it. The primary objective is to seal the cavity against air and water migration.
The best choice is a polyurethane, closed cell, minimal expanding foam. Dow, Hilti, OSI are three of the more popular brands.

An important factor in my opinioon is a pro gun for appling the foam, makes a huge difference in control.

Re: What type of Foam should be used
I'd agree with randy and anthony. The choices mentioned are all applied using a "pro gun" which allows a bit a adjustment for control. The worst that can happen is that they overfill and have a mess to clean up, or under-fill and have to hit it a second time. The low-expansion variety will NOT bow the frame no matter how much you put in.... I would agree with Eco, however, on the point that you really should let the installer use what he prefers. If you are not confident in his choice, then perhaps you picked the wrong installer... that goes for different foam brands, foam v fiberglass, etc.... One thing I will say, if your installers show up with a case of cans of Great Stuff, that is a pretty telling sign.

Guns are 10X better for control but you would be surprised, some installers still insist on can and straw.HomeSealed wrote:I'd agree with randy and anthony.

Using it is what is ultimately key.

The can and straw foam is a messy nightmare to use. The guns are the only way to go.
Re: What type of Foam should be used
Are you going with double or triple pane soft Lite? and which glazing, spacer system did you opt for? Yes, keep us posted. I am considering Soft-Lite as well. thanks
Re: What type of Foam should be used
Thanks for the advice. I spoke to the installer and they indicated they use OSI low expansion foam.
The windows look great and I am thorougly satisfied.
Hootie - As far as the window I went with. I went with the double pane barrington soft-lite window with low-e/argon.

The OSI foam is also known as TeQ.

Re: What type of Foam should be used
We've been using it for a couple years now with good results. Doesn't expand as much as some others, but that can be a good thing. Overall, I think the most important thing is using whichever product you are comfortable with to avoid gaps and/or messes.anthony wrote:The OSI foam is also known as TeQ.
