A gas fireplace provides warmth and ambiance, but when not in use, it can become a source of drafts and energy loss. A gas fireplace draft cover is a simple yet effective solution to prevent cold air from entering and warm air from escaping. These covers come in various styles, from magnetic inserts to custom-fit panels, helping improve energy efficiency while maintaining the fireplace’s appearance. Whether you’re looking to reduce heating costs or eliminate chilly drafts, this guide covers everything you need to know about choosing and using a gas fireplace draft cover.
Why You Need a Gas Fireplace Draft Cover
Even when turned off, gas fireplaces can allow outside air to seep into your home through the flue or vent. This creates drafts that make your living space feel colder and force your heating system to work harder. A draft cover acts as a barrier, blocking unwanted airflow and improving insulation. In winter, this helps retain heat, while in summer, it prevents warm outdoor air from entering. The result is a more comfortable home and lower energy bills.
Another benefit of using a draft cover is preventing debris, dust, and pests from entering through the fireplace opening. Insects, small animals, and even leaves can find their way inside if the fireplace isn’t properly sealed. A well-fitted cover keeps these nuisances out while maintaining cleanliness. Additionally, some covers provide an extra layer of safety by reducing the risk of accidental gas leaks or backdrafts when the fireplace is not in use.
Draft covers also help preserve the fireplace’s interior components. Moisture and cold air can cause wear and tear on the burner, logs, and venting system over time. By sealing the opening when the fireplace is idle, you extend its lifespan and reduce maintenance needs. Whether your fireplace is rarely used or simply shut off during warmer months, a draft cover is a smart investment for efficiency and protection.
Types of Gas Fireplace Draft Covers
The most common type of draft cover is a magnetic sheet that adheres directly to the fireplace opening. These are easy to install and remove, making them a convenient option for seasonal use. Magnetic covers are typically made of insulated materials like foam or fiberglass, which improve thermal resistance. They work best on metal-surround fireplaces, as they require a smooth, magnetic surface for proper adhesion.
For fireplaces without a magnetic frame, a custom-fit insert or panel may be a better choice. These covers are often made of clear acrylic, tempered glass, or decorative metal and fit snugly into the opening. Some models include adjustable brackets or tension rods to hold them in place. While slightly more involved to install, these covers offer a more permanent solution and can be designed to match your home’s décor.
Another option is an inflatable draft stopper, also known as a fireplace pillow. These are made of durable plastic and inflate to fill the entire flue or firebox, creating an airtight seal. They are particularly useful for large or irregularly shaped openings. While not as visually appealing as other options, they are highly effective at blocking drafts and can be easily deflated and stored when the fireplace is in use.
How to Choose the Right Draft Cover
When selecting a draft cover, the first consideration is compatibility with your fireplace. Measure the width, height, and depth of the opening to ensure a proper fit. Check whether your fireplace has a metal frame for magnetic covers or if you’ll need an alternative attachment method. If you’re unsure, consult your fireplace’s manual or a professional for guidance.
Material and insulation properties are also important. If energy efficiency is your primary goal, look for covers with insulating layers like foam or thermal fabric. For a more decorative approach, consider glass or metal covers that blend with your interior design. Some covers are even designed with faux finishes to mimic brick or stone, maintaining the fireplace’s aesthetic while sealing drafts.
Ease of use is another factor. Magnetic and inflatable covers are quick to install and remove, making them ideal for seasonal use. If you prefer a more permanent solution, a custom panel or insert may be worth the investment. Consider how often you use your fireplace and whether you’re willing to remove the cover frequently before making a decision.
Installing a Gas Fireplace Draft Cover
For magnetic covers, installation is straightforward—simply align the cover with the fireplace opening and press it into place. Ensure the surface is clean and dry for maximum adhesion. If the cover doesn’t stick well, check for any gaps or uneven surfaces that may need adjustment. Some covers come with adhesive strips for added security.
Custom panels or inserts may require more precise installation. Follow the manufacturer’s instructions carefully, as some models need brackets or clips to stay in place. If drilling is necessary, mark the spots beforehand and use appropriate hardware to avoid damaging the fireplace surround. For inflatable stoppers, insert the deflated pillow into the flue and inflate it until it fits snugly.
After installation, test the seal by feeling for drafts around the edges. If air is still leaking, consider adding weatherstripping or adjusting the cover for a tighter fit. A well-installed draft cover should significantly reduce airflow and improve insulation.
Maintaining and Storing Your Draft Cover
To keep your draft cover in good condition, clean it regularly with a soft cloth and mild cleaner. Avoid harsh chemicals that could damage the material. For magnetic covers, check the adhesive or magnetic strength periodically and replace it if it weakens. Inflatable stoppers should be inspected for punctures or leaks before each use.
When the fireplace is in use, store the cover in a dry, safe place to prevent damage. Foldable or inflatable covers can be kept in a closet or storage bin, while rigid panels may need a designated spot where they won’t get scratched or bent. Proper storage ensures the cover remains effective for years.
If your cover becomes worn or no longer fits properly, consider replacing it. Over time, materials can degrade, reducing their insulating properties. Investing in a high-quality cover and maintaining it properly will maximize its lifespan and performance.
