Questions & Answers

What is the insulation value of this material?

In the form of foam, it has a low expansion rate. As far as insulation goes, it works as most spray foams do. It would be better if a professional did the spraying if the project was large because the coat would get quite thick.

How will this affect a leaky duct flange on the ceiling?

To prevent leaks from accumulating on top of this stuff, it is designed to fill in openings so that it can expand and seal. If the ceiling and flange are in contact or if there is a gap between the two, tape the foil ducting. If the flange can be loosened to create a space, fill it, and reattach it. You should be able to use this product after tightening.

It can be used to stop drafts in winter and removed in spring, can it?

As the name implies, the product is not really removable. If you apply it, it bonds to whatever surface you put it on. To stop drafting, you might want to consider a more permanent solution. I really like how it works.

If there is overflow in the foam, can it be trimmed?

I don't see an issue with that. Most of the time, foam does not expand much, so trimming is not required. As an added bonus, it does not stain as much as yellow foam.
