- Energy Efficiency: Our fireplace blocker effectively prevents drafts, odors, and debris from entering your home. In winter, it minimizes heat loss, keeping your space warm while reducing heating costs. In summer, it prevents cold air from escaping, blocks heat from entering, and helps your air conditioner use less energy, achieving significant savings on energy bills. - Powerful Magnetic Design: Equipped with twelve strong magnets that can each support a suction force of 1.2 T, this blanket adheres securely to your fireplace frame without falling off. The design blends seamlessly into your fireplace, ensuring a discreet appearance. Please note that the magnets are not heat-resistant and should not be exposed to high temperatures for extended periods. - High-Quality Material: Constructed from thickened, flame-retardant sponge, this magnetic fireplace cover is designed for durability. Its unique structure prevents any movement of the inner lining, while the strong magnets ensure a tight seal against air leaks. It is essential to note that the magnets will only attach to metal frames containing iron, cobalt, or nickel. - Easy Installation and Storage: Simply position the protruding side of the magnet against your fireplace's metal frame. The blocker will automatically adhere, ensuring a secure fit without the need for additional tools. When not in use, the blocker can be easily folded and stored without taking up much space. - Practical Applications: Ideal for use during winter months to maintain warmth and reduce heating costs, and during summer to enhance air conditioning efficiency. Perfect for homes with traditional fireplaces or wood stoves, this blocker is an essential addition for energy-conscious individuals looking to improve home comfort.
