FAQs
What should I look for in a fireplace draft stopper?
Look for a stopper that fits your fireplace dimensions snugly to prevent drafts. Consider materials like durable silicone or magnetic seals for better insulation. Ensure it’s easy to install and remove for convenience.

Measure the width and height of the fireplace opening at its widest points. Account for any irregularities or protrusions like handles. Most stoppers are adjustable, but accurate measurements ensure a tight fit.
