39″x32″ Fireplace Cover, Magnetic Blocker Blanket
Features: High-quality thickened Oxford fabric, sponge fill, 12 magnets with up to 1.2 T suction force, designed for metal fireplace frames. Excluded from prolonged exposure to high heat as magnets aren’t heat resistant. This blocker provides strong airtight adhesion and prevents cold air from entering and warm air from escaping. Best for large metal-frame fireplaces where a robust magnetic seal is desired. Limitations: Optimal performance depends on an iron/steel frame; not ideal for non-metal surfaces.
Magnetic Fireplace Cover 39×32 – WHUMSDOG
Features: Twelve built-in magnets around a thickened flame-retardant Oxford cloth cover; magnetic strength supports secure attachment to metal frames. The blocker’s design reduces drafts, odors, and debris, and helps conserve energy in winter while keeping airflow managed in summer. Best for users with iron-based frames who want a seamless, nearly invisible install. Caution: Do not rely on magnets for high-temperature exposure long-term; remove before long-term high heat to preserve magnet strength.
Magnetic Fireplace Cover 38″x31″ – WHUMSDOG
Features: Twelve magnets providing strong attachment to metal frames, thick Oxford cloth, sponge filling, and a split lining to prevent inner movement. Best for mid-sized metal fireplaces where a tight seal is desired and aesthetics matter (black blends with most mantels). Consideration: Magnets are not heat resistant for long high-heat exposure.
Fireplace Cover, Draft Stopper for Brick Fireplace – WINTACK
Features: Velcro installation with hooks included; designed for brick fireplaces without steel frames, using strong adhesive backing for secure attachment. Energy-saving approach by stopping heat loss through the flue in winter and blocking heat entry in summer. Best for brick fireplaces or stone surfaces where metal frames are not available. Limitation: Velcro-backed design may require reattachment on textured surfaces over time.
Magnetic Fireplace Draft Cover – CADARA 33″ W x 29″ H
Features: 12 magnets embedded for easy attachment to iron frames; black stylish look; designed to fit standard metal fireplace frames. Best for users seeking a compact option with magnetic ease and energy-saving goals. Caution: Suitable primarily for metal frames; not ideal for non-metal installations.
Buying Guide
- Which installation method is best for your fireplace?
- Metal frames vs brick/stone surfaces: magnets work best on metal; Velcro works on brick/stone with proper backing.
- Heat exposure considerations: magnets aren’t designed for long-term high-heat zones; install after the fire is extinguished if using magnetic blockers.
- Size and fit: measure the fireplace opening to select a blocker blanket with adequate width and height for full coverage without gaps.
- Energy goals: look for blockers advertised to reduce heat loss in winter and block hot air in summer for maximum savings.
- Aesthetics and material: choose Oxford cloth or flame-retardant materials for durability and a neat appearance that blends with interiors.
- Additional installation features: hook-and-loop tapes and extra hooks can help with brick or stone fireplaces that lack metal frames.
Practical Tips
- Install blockers once the fireplace is completely cooled to avoid fabric damage.
- Regularly check magnets and seams for wear and reattach or replace as needed.
- For brick fireplaces, favor products with hook-and-loop and adhesive backing for a secure seal without drilling.
FAQ
- Q: Do these blockers fit all fireplace sizes? A: Sizes vary; select a blocker with dimensions that cover the fireplace opening with a small overhang for best seal.
- Q: Can I use magnets on non-metal fireplaces? A: Magnets require metal frames or a metal surround to attach securely.
- Q: Will these blockers affect combustion or ventilation? A: They are designed to seal drafts when the fireplace is not in use; always extinguish flames and ensure proper ventilation when needed.
- Q: How durable are the materials? A: Most blockers use Oxford cloth or similar flame-retardant fabrics with sponge filling for insulation and durability.
- Q: Are they easy to install? A: Yes; magnetic blockers require metal frames, while Velcro-based options suit brick and stone frames with adhesive-backed loops.
- Q: Will these reduce heating costs? A: By reducing heat loss in winter and minimizing heat gain in summer, they can contribute to lower energy usage when used correctly.
