A fireplace can be a beautiful and comforting focal point in a home, adding warmth and character. However, when a fireplace isn’t in use, it can become a source of drafts, energy loss, and even attract unwanted pests. Covering the fireplace opening is a practical solution to these problems, enhancing energy efficiency and improving overall home comfort. This comprehensive guide will explore various methods for covering your fireplace opening, helping you choose the best option for your needs and aesthetic preferences.
Understanding the Need to Cover Your Fireplace
Fireplaces, especially older ones, can be surprisingly inefficient. The chimney acts as a natural vent, drawing air up and out of the house, even when the damper is closed. This “chimney effect” can significantly increase heating and cooling costs, as your HVAC system has to work harder to compensate for the lost conditioned air. Covering the fireplace opening effectively seals this vent, preventing drafts and reducing energy waste.
Beyond energy efficiency, covering the opening can also prevent debris, insects, and even small animals from entering your home through the chimney. This is particularly important if you live in an area with a significant wildlife population or if your chimney is not properly capped.
Methods for Covering Your Fireplace Opening
Several options exist for covering a fireplace opening, ranging from simple, temporary solutions to more permanent and aesthetically pleasing options. The best choice depends on your budget, DIY skills, and how frequently you plan to use the fireplace.
Temporary Solutions: Simple and Effective
Temporary solutions are ideal for homeowners who occasionally use their fireplace or are looking for a quick and inexpensive way to address drafts. These methods are typically easy to install and remove, offering flexibility.
Plastic Sheeting and Tape
This is the simplest and most cost-effective option. Simply cut a piece of heavy-duty plastic sheeting slightly larger than the fireplace opening. Secure it to the fireplace surround using strong tape, such as duct tape or painter’s tape. While effective at blocking drafts, this method is not particularly attractive. This serves as a good temporary fix until you come up with something better. Make sure the plastic is heavy enough to withstand any pressure from drafts.
Cardboard and Insulation
A more robust temporary solution involves cutting a piece of cardboard to fit snugly inside the fireplace opening. Then, insulate the cardboard with fiberglass insulation or foam board. This creates a more effective barrier against drafts and heat loss than plastic sheeting alone. Ensure the cardboard is a snug fit to properly seal the fireplace.
Fireplace Draft Stoppers
These are inflatable pillows designed specifically to block fireplace flues. They come in various sizes to fit different fireplace openings and are easy to install and remove. Simply inflate the pillow inside the flue to create an airtight seal. This is a convenient option for those who want a reusable and effective solution. Draft stoppers are a very effective solution and should be considered.
Semi-Permanent Solutions: Balancing Function and Aesthetics
Semi-permanent solutions offer a good balance between functionality and aesthetics. They are more durable and visually appealing than temporary options but can still be removed if you decide to use the fireplace.
Fireplace Screens with Insulating Backing
Standard fireplace screens primarily serve to prevent sparks from escaping the fireplace. However, you can enhance their draft-blocking capabilities by adding an insulating backing. Attach a layer of fiberglass insulation or foam board to the back of the screen to create a more effective barrier against drafts. Choose a screen that complements your home’s decor for a more polished look.
Custom-Fit Foam Inserts
These inserts are made from dense foam and are cut to precisely fit your fireplace opening. They provide excellent insulation and effectively block drafts. You can often customize the foam to match the shape and size of your fireplace. While functional, they may not be the most visually appealing option.
Magnetic Fireplace Covers
Magnetic fireplace covers are an increasingly popular option. These covers are made from a flexible magnetic material that adheres to the metal frame of the fireplace opening. They are easy to install and remove and can be customized with various designs and finishes. The magnetic seal provides a tight barrier against drafts. These can be a more attractive and effective solution.
Permanent Solutions: Long-Term Energy Savings and Aesthetics
Permanent solutions are ideal for homeowners who do not plan to use their fireplace in the foreseeable future and are looking for a long-term solution that enhances the aesthetic appeal of their home.
Glass Fireplace Doors
Glass fireplace doors are a popular choice for those who want to maintain the visual appeal of their fireplace while blocking drafts. They come in a variety of styles and finishes to complement any decor. High-quality glass doors can significantly reduce heat loss. Ensure the doors fit snugly and have a good seal to maximize their effectiveness.
Fireplace Inserts
Fireplace inserts are self-contained heating units that are installed inside the existing fireplace opening. They can be powered by gas, electricity, or wood pellets and provide efficient and supplemental heat. When not in use, they effectively seal the fireplace opening, preventing drafts. However, this option requires professional installation and can be more expensive than other solutions.
Drywall or Other Permanent Coverings
If you are certain that you will never use your fireplace again, you can permanently close it off with drywall or another permanent covering. This involves building a frame inside the fireplace opening and covering it with drywall, brick, or stone to match the existing fireplace surround. This option provides the most effective seal against drafts and completely transforms the look of the fireplace. This is a very permanent solution and should be carefully considered.
DIY vs. Professional Installation
The decision to tackle a fireplace covering project yourself or hire a professional depends on your DIY skills, the complexity of the project, and your budget. Simple solutions like plastic sheeting, cardboard, and draft stoppers are easy to install yourself. Semi-permanent solutions like fireplace screens with insulating backing and custom-fit foam inserts can also be DIY projects for homeowners with some basic skills. However, permanent solutions like installing glass fireplace doors, fireplace inserts, or drywall coverings are best left to professionals. These projects require specialized tools, knowledge, and experience to ensure proper installation and safety.
Choosing the Right Material
The choice of material for covering your fireplace opening depends on the method you choose and your aesthetic preferences. For temporary solutions, plastic sheeting and cardboard are readily available and inexpensive. For semi-permanent and permanent solutions, consider materials that are durable, insulating, and visually appealing.
- Insulation: Fiberglass insulation, foam board, and mineral wool are excellent choices for providing insulation.
- Coverings: Wood, drywall, brick, stone, and metal can be used to create a visually appealing and durable covering.
- Sealants: Caulk, weather stripping, and foam sealant can be used to create an airtight seal around the edges of the covering.

By implementing these measures in conjunction with covering the fireplace opening, you can create a more energy-efficient and comfortable home.
Why should I cover my fireplace opening when it’s not in use?
Leaving your fireplace opening uncovered allows drafts to enter your home, making your heating system work harder and increasing energy costs. Uncovered openings also provide an easy entry point for small pests, dust, debris, and even rain, which can damage your hearth and surrounding areas. Effectively covering your fireplace helps maintain a comfortable indoor temperature, prevents unwanted intrusions, and protects your home from potential damage.
A covered fireplace creates a barrier that seals off the chimney flue, preventing the exchange of air between your home and the outside environment. This barrier minimizes heat loss in the winter and keeps cool air inside during the summer, resulting in significant energy savings over time. Moreover, covering the opening prevents soot and other contaminants from entering your living space, improving indoor air quality and reducing the need for frequent cleaning.
What are the different types of fireplace covers available?
Various options exist for covering your fireplace opening, each offering different levels of protection and aesthetic appeal. These include fireplace doors, fireplace screens, chimney balloons, magnetic fireplace covers, and temporary solutions like heavy-duty plastic sheeting. The best choice depends on your budget, how often you use your fireplace, and the level of sealing you require.
Fireplace doors offer a permanent and decorative solution, providing a tight seal and enhancing the fireplace’s appearance. Fireplace screens offer a barrier but aren’t airtight. Chimney balloons are inflatable devices that seal the flue, while magnetic covers provide a quick and easy way to block the opening. Temporary solutions are best for short-term protection or when undertaking renovations.
How do I measure my fireplace opening to ensure a proper fit?
Accurate measurements are crucial to ensure your chosen fireplace cover fits correctly and effectively seals the opening. You’ll need a measuring tape and possibly a helper for larger openings. Measure the width and height of the fireplace opening at its widest and tallest points. Also, measure the depth of the firebox to determine the space available for a cover that sits inside the opening.
Record all measurements carefully, and if you are ordering a custom-made cover, provide these exact dimensions to the manufacturer. If you are purchasing a pre-made cover, compare your measurements to the product specifications to ensure a snug and secure fit. Consider slightly larger sizes if your measurements fall between standard sizes, allowing for minor adjustments during installation.
Can I use a blanket or cardboard to cover my fireplace opening?
While a blanket or cardboard might seem like a convenient short-term solution, they are not ideal for covering your fireplace opening. These materials are not designed to withstand the temperature fluctuations within a chimney and can pose a fire hazard if embers remain. Moreover, they often don’t provide an airtight seal, rendering them ineffective for blocking drafts and pests.
Blankets and cardboard are also susceptible to absorbing moisture and odors from the chimney, potentially creating an unpleasant smell in your home. For even temporary solutions, consider using materials specifically designed for fireplace protection, such as heavy-duty plastic sheeting or a purpose-made fireplace cover, which offers better insulation and safety. These alternatives are more durable and less likely to create hazards.
How do I install a chimney balloon or fireplace plug?
Installing a chimney balloon or fireplace plug is a relatively simple process, but it’s crucial to follow the manufacturer’s instructions carefully. First, ensure the fireplace is cold and free from any embers or ash. Then, insert the deflated balloon or plug into the chimney flue, positioning it above the fireplace opening.
Next, inflate the balloon according to the instructions, using a hand pump or similar device. Be careful not to overinflate, as this could damage the balloon or chimney. Once inflated, the balloon should create a tight seal against the chimney walls, effectively blocking drafts. Fireplace plugs, made of dense foam, are simply pushed into place until they fit snugly. Regularly check the seal and adjust as needed to maintain its effectiveness.
What safety precautions should I take when covering my fireplace?
Safety should always be your top priority when covering your fireplace opening. First and foremost, ensure that the fireplace is completely cold and free from any lingering embers or ash before installing any cover. This prevents the risk of fire or carbon monoxide poisoning if the cover isn’t fire-resistant.
Always remove the cover before lighting a fire in the fireplace. Failing to do so can lead to a build-up of dangerous gases and potentially ignite the cover, causing a fire hazard. Regularly inspect your fireplace cover for any signs of damage or wear and tear, and replace it promptly if necessary. Following these precautions ensures the safe and effective use of your fireplace cover.
How can I clean and maintain my fireplace cover?
Cleaning and maintaining your fireplace cover will help prolong its lifespan and keep it looking its best. The specific cleaning method depends on the type of cover you have. For fireplace doors and screens, use a glass cleaner or a mild soap and water solution to remove soot and grime. Rinse thoroughly and dry with a soft cloth.
For chimney balloons and fireplace plugs, periodically remove them and wipe them down with a damp cloth. Avoid using harsh chemicals or abrasive cleaners, as these can damage the material. Inspect the cover regularly for any signs of wear and tear, such as rips or tears, and repair or replace it as needed. Proper cleaning and maintenance will help your fireplace cover continue to effectively protect your home.
