Questions & Answers

How do I figure out how big the damper area needs to be in order to insulate it?

There's a "What chimney product is right for me" tool on the Cleverly Solved website that shows you photos of various types of dampers and fireplaces, as well as how to size them.

Is it possible to use it with gas logs that do not require a chimney?

When the ventless gas logs aren't in use, that is.

Why can't it be used with gas logs that have been vented? You'd take it out before you started a fire, right?

Vented gas logs are required by building code to keep the flue open at all times, but most professional installers disable or clip the damper, preventing it from closing completely. The reason for this is to ensure that you do not light the gas log with the damper closed, allowing fumes to back up into the house. If you want to use the Flueblocker, simply turn off the gas logs so that you can't accidentally turn them on while it's being installed. By disabled, I mean that the pilot is out, the gas ball valve is closed, and there is no way to start it without first removing the Flueblocker.

How does this product's R factor look?

We can't get it tested for an exact R value because R value ratings are limited to windows, doors, and insulation. However, we can compare it to R 13 with an air barrier in terms of performance.

It is highly recommended

5/5

In an older home, I used this product to seal a very drafty chimney. It was delivered quickly and is well-made. It's of good quality and simple to put together. It's already making a difference; the room is several degrees warmer, which is very welcome during the cold winter months! This product comes highly recommended if you want to seal your chimney.
