A broken damper can waste 8-30% of your home’s heating & cooling energy. Choose the right damper for your chimney type.
Top-Mount Dampers (Lock-Top Style)

Choosing the right damper
Top-mount dampers offer the best energy savings but cost more upfront. Throat dampers are cheaper but don’t seal as tightly. Inspect yours: if cold drafts come down when closed, your seal is bad.
