Osburn: Matrix

This updated version of the Matrix wood insert will seduce you with an average particle emission rate as low as 1.54 g/h. The latest modifications made to this box are well in tune with the industry standards required for 2020. Although it retains a unique style that is both massive and sleek, we have reviewed the door mechanism to make it more functional. Adding a set of intermediate trim panels may be required to complete your masonry hearth. Always the same legendary Osburn quality.
