Den said:Fred, when that ad for the insulation stripping mentions smoke, I think it's a reference to the good ol' "slammer" installs, where the insert vents directly into the masonry. If you have a full chimney liner, smoke wouldn't be an issue. The point is that the metal surround doesn't really form a tight seal on the hearth masonry. No smoke, just heat loss. Yeah, you probably wouldn't know the difference without doing a before/after comparison, but the same could probably be said for weatherstripping the front door of your house.![]()
This guy I don't think is interested in making a block off plate either. But I will chat with him when he comes out Wed more about it.
