This specialized sealant utilizes magnetic force to create a tight seal between a steel door and its frame. A flexible magnetic strip embedded within a carrier material, often vinyl or rubber, is affixed to the door frame. When the door closes, the magnet attracts to the steel, forming a barrier against drafts, moisture, and pests.
Effective sealing around entry points contributes significantly to energy efficiency by minimizing air leakage. This translates to reduced heating and cooling costs, a smaller environmental footprint, and improved indoor comfort. Historically, various methods have been employed to seal door gaps, but advancements in materials and magnetic technology offer a durable, low-maintenance, and readily installable solution. This approach provides superior sealing compared to traditional methods like felt or foam, which can degrade over time.
