At Build Show Live, architect Steve Baczek, Architect, talks with Jason Hamachek, Director of Installed Sales at EarthCore, about new fireplace technology aimed at energy-efficient homes. Jason explains a gas-only open hearth insert with a sealed damper that closes airtight when the fireplace is off, paired with a fan that induces draft and adjusts to household pressure. They also cover a variable makeup air system that monitors indoor and outdoor pressure and responds when appliances like dryers or range hoods compete for air. The conversation turns to the Icelandic pumice used in Isokern fireplaces, modular custom sizing, manufacturing, and delivery timelines.
