Buying Guide

Measure the opening accurately

Record the fireplace or stove opening width and height so magnetic covers or blankets match the dimensions and create an effective seal

Check mounting and magnet strength

Look for covers with multiple magnets or magnet-mounting options to ensure a secure hold on varied surround materials like metal or stone

Choose fire-resistant materials

Select products with fireproof blankets or fire-resistant fabrics to maintain safety if embers or heat are present

Consider multiple installation methods

Products that offer several install methods (magnets, adhesive strips, or hook-and-loop) adapt to different fireplace frames and improve fit

Balance size and portability

Smaller, lighter covers are easier to store and handle, while larger, tailored sizes provide better draft protection for bigger openings
