US Fireplace Products Seal Tight Damper 9″ x 13″
The 9″ by 13″ version focuses on an air tight seal to minimize heat loss. It uses a two-gasket system for improved efficiency and energy savings. The primary gasket sits in a channel, while a secondary liquid gasket lies underneath the front lid, reinforcing the seal during cold months. Best for small to mid-size masonry fireplaces where precise draft control matters. Limitations include potential fit sensitivity for non-standard hearth openings.
US Fireplace Products Seal Tight Damper 13″ x 13″
This 13″ x 13″ damper uses the same high-tech dual-gasket system to deliver an air tight seal for larger masonry chimneys. It reduces heat loss and lowers energy costs by maintaining a stable indoor temperature. Best for standard to larger wood-burning fireplaces. A note: ensure the damper frame fits properly within the chimney throat to maintain seal integrity.
US Fireplace Products Seal Tight Damper 13″ x 18″
An extended 13″ x 18″ size suits larger masonry systems, offering a robust air tight seal with the dual-gasket approach. Best for homeowners with bigger brick chimneys or rare large openings. Consider potential weight and width constraints when retrofitting existing chimneys.
US Fireplace Products Top Damper Plus – 13″ x 13″
Designed for energy efficiency, this top damper features a tight seal to reduce heating and cooling costs while providing draft protection. It offers quick and easy installation without complex wiring or fusible links, and includes a limited lifetime warranty. Best for homeowners who want a straightforward upgrade with long-term assurance. A caveat: ensure compatibility with existing flue hardware and collar sizes.
US Fireplace Products Top Damper Plus – 9″ x 13″
Another compact top damper option, this 9″ x 13″ variant emphasizes energy efficiency and a tight seal for smaller fireplaces. It’s notable for easy installation and a limited lifetime warranty. Best for homeowners prioritizing budget-friendly upgrades without sacrificing performance. Avoid this if the chimney throat is irregular or wider than standard 9×13 openings, which could affect sealing.
Rockford Chimney Supply Premier Cap 9×13
This 9×13 damper cap is built from 304 stainless steel with a mesh lid and a removable lid for easy damper access. Best for homeowners wanting durable corrosion resistance and simple maintenance. It protects the chimney top from rain and debris while allowing easy damper inspection. Limitation: may require compatible mounting hardware and precise fit to avoid rain ingress around edges.
Buying Guide
- What is your fireplace type? Choose dampers for masonry, wood-burning fireplaces, and chimneys with standard throat sizes. Caps are best when you need rain and debris protection.
- Size and fit: Measure the opening accurately. Mismatched sizes can cause leaks and reduced efficiency.
- Seal design: Dual-gasket dampers offer stronger seals but may require precise installation to prevent leaks.
- Material: Stainless steel and aluminum hybrids resist rust and weathering; consider climate and exposure.
- Installation: Look for products with simple installation or warranty coverage for peace of mind.
- Maintenance: Removable lids and accessible dampers simplify routine inspection and cleaning.
FAQ
- What is the difference between a chimney cap and a damper?
– A cap blocks rain and debris at the top of the chimney; a damper seals the fireplace opening to control drafts and heat loss. - Will a damper improve energy efficiency?
– Yes, especially dual-gasket dampers, which minimize air leakage when closed. - Can I install these myself?
– Many models are designed for easy installation, but verify compatibility with your chimney and follow manufacturer instructions. - What size should I choose?
– Measure the interior throat or opening; pick a size that matches the chimney’s dimensions for a proper seal. - Are stainless steel caps durable in all climates?
– Stainless steel resists corrosion and is suitable for wet or salty environments, offering longer service life. - Do these dampers require professional inspection?
– Having a professional inspect after installation ensures the measure is correct and the seal is secure, especially for older chimneys.
