We originally designed this door for Norwegian builders whose demands were to maximize viewing area while offering the highest quality fireplace door possible. Over the years, thousands of new homes in Europe have received this door and we are finally offering this design stateside. Quite possibly the world’s thinnest Custom Zero Clearance door frame offered by a premium door manufacturer, the Norwegian boasts the largest glass to frame ratio offered in the industry. The thin handcrafted steel frame offers rigidity without compromising viewing area, allowing for the largest glass we can offer for the opening. The frame is powder coated in a durable textured black finish and the channel handles come standard in black but can be upgraded to Stainless Steel or Antique Brass. Offered in a CV2-tracked bi-fold door with glass options of Bronze, Clear and Grey as standard. Upgrade your home’s look without compromising any of the grand look and luster of your fireplace.

Special “Z”

The Special Z offers a classic look at an affordable price. The unit is designed from anodized aluminum and features bi-fold full swing trackless doors. Available only as an inside fit, the unit incorporates a 7/8″ wide frame. Air space is allowed from the top, sides or bottom providing the same air flow as the zero clearance fireplace.

Complete Reface

A zero-clearance fireplace can provide a home with years of performance; however, the look can become outdated and not match a room’s current décor. A simple solution to enhance and provide your existing fireplace with a fresh appearance is a Complete Reface Door Enclosure. Constructed of 1″ steel square tubing for a welded frame. Please note that the door needs to be installed in such a manner that it sits on the hearth for support.

Direct Vent

Enhance the appearance of an existing direct-vent fireplace by adding a Direct-Vent Fireplace Accessory Mesh Door. Three different louver styles are available including the Leaf Scroll, Diamond or Navaho Louver to complement any room. Accent any room by adding an eye appealing mesh door that attaches to an existing fireplace door with extra strength magnets. It’s as easy to install and makes for easy glass cleaning. Perfect for any direct-vent fireplace.


Thermo-Rite’s stock Z-Doors are made as inside fits. We use Air Studs™ or an Air Draft Bar™ to elevate the frame so that it maintains the cooling air intakes located inside the firebox. In most applications, we allow an air space between the outside of the enclosure and the firebox opening. The Z-Door is a sleek, full-framed, tarnish free anodized aluminum enclosure.


Z-Decor is an anodized aluminum enclosure with a  3/4″ wide frame. It is available as an inside fit only.  Air space is allowed on the sides, top, bottom or combination to provide the same air flow as the manufacturer of the zero clearance fireplace.
