Buying Guide
What should you consider when choosing an over-door curtain heater?
- Door size and fit: Measure door width and height precisely. Look for curtains sized to cover at least 36″ x 82″ to ensure complete sealing on most exterior doors.
- Closure method: Magnetic closures are convenient and hands-free but verify magnet strength and alignment for your door frame. Hook-and-loop attachments help with uneven frames.
- Material and durability: Oxford fabric and dense padding offer better wind resistance and long-term durability than thin plastics. EVA offers a soft touch and easy cleaning but may be less heat-retentive than thicker layers.
- Light control and privacy: If you want blackout or privacy, choose products marketed for blackout performance or thicker fabric. For visibility with insulation, options with a clear window are available.
- Energy savings: Insulated curtains reduce heat loss in winter and keep cool air from escaping in summer. Look for multi-layer designs and sealed edges for best performance.
- Installation and maintenance: Consider products that come with easy-install strips or ties. Reusability and machine-washable fabrics make maintenance simpler.
