The Ice Breaker Chimney Cap-Damper – 3/4 is a compact, high-performance chimney top solution engineered to manage the challenges of winter weather while offering precise control over fireplace draft. This all-in-one design combines the protective features of an insulated cap with the energy-saving benefits of a built-in damper—making it an ideal source of inspiration for homeowners and builders in cold climates or moisture-prone regions.
Smaller in scale than full-size dampers, the 3/4 version is built for tighter flue tops or existing stacks with limited space, while still offering the same intelligent functionality. Its sturdy, weather-resistant design keeps rain, snow, and animals out, while the damper mechanism provides greater control over heat retention and air flow.
The integrated damper allows you to seal the chimney flue when not in use—preventing heated indoor air from escaping and stopping cold drafts from entering the home. Paired with its ice-resistant top and air-insulated walls, this chimney cap-damper unit performs year-round with minimal maintenance.
This 3/4 configuration is especially useful for retrofit installations or smaller flue diameters where traditional dampers may not fit.
Whether topping a metal flue or traditional masonry chimney, the Ice Breaker Cap-Damper delivers both visual simplicity and mechanical function. It eliminates the need for an interior throat damper, creating a more efficient and repair-friendly chimney structure. From new constructions to upgrades of aging flue systems, this unit supports a cleaner, more energy-conscious fireplace experience.
Its sturdy build and discrete profile also make it a natural fit for homes that value utility-focused design and architectural consistency.
The Ice Breaker Chimney Cap-Damper – 3/4 may be small in size, but its impact is substantial. It combines multiple layers of chimney protection—draft regulation, moisture deflection, and freeze resistance—into a single, cleanly executed component. This makes it one of the most efficient upgrades for chimney systems exposed to varied or extreme weather conditions.
When building or upgrading your fireplace design, this cap-damper hybrid proves that even the smallest details can dramatically affect home comfort and system longevity.
