Closing a fireplace effectively, particularly for energy savings, often involves sealing the opening or the damper. Based on common practices and methods for preventing drafts, here are ways to close or seal your fireplace:
Methods for Sealing Your Fireplace
Sealing a fireplace goes beyond simply closing the built-in damper; it often involves creating a more robust barrier to prevent conditioned air from escaping and cold air from entering your home.
Here are some approaches, including methods mentioned in the reference:
-
Permanently Sealing the Damper with Silicone:
- This is considered a highly effective, albeit permanent, solution.
- It involves using silicone sealant to fill in and seal the damper mechanism and surrounding gaps.
- Note: This method permanently disables the use of the fireplace for fires, as the damper will be sealed shut.
-
Creating a DIY Plug:
- You can construct a custom plug designed to fit snugly either within the damper opening or the main fireplace opening.
- This typically involves using materials like rigid insulation board covered with fabric for a better seal and appearance.
- Following steps similar to making a fireplace opening plug allows you to create a plug specifically for the damper area if desired.
- This offers a semi-permanent solution that can be removed if you decide to use the fireplace again in the future.
-
Buying a Damper Plug:
- Commercially available damper plugs or chimney balloons are designed to inflate or expand within the chimney flue just above the damper.
- These products create a tight seal to block drafts.
- This is a readily available option that doesn't require permanent alteration to the fireplace structure.
These methods focus on creating a seal to improve home energy efficiency by preventing drafts and heat loss through the chimney. Always ensure the fireplace is thoroughly cleaned and cool before attempting any sealing work. If you intend to use the fireplace again, choose a non-permanent method like a removable plug.
