Grand Seal Sealed Fireplace Door

Description

The Grand Seal is Wilkening’s heaviest sealed door, with angle-iron swing sections that carry a gasket around every glass panel and a second gasket that seals the frame against the face of the masonry fireplace. Wilkening says it has been shown to prevent back-smoking at negative house pressures down to -25 Pa, so a traditional open wood-burning fireplace can still be used in tightly built homes. It ships with ceramic glass and wood handles as standard, and can be dressed with Ancient Iron trim or Prairie-style doors in rectangular or arched frames. The same door appears on a legacy page of the site under its earlier name, Ultimate Seal.
