The Harvia WL450 Protective Sheath is specifically designed and approved for use with Harvia’s wood-heated stoves, including the M1, M2, M3, and M3 SL models. By significantly reducing the required safety distance to combustible materials, it allows your wood-burning heater to fit comfortably into more compact sauna spaces without compromising safety. Tailored to match the shape of the heater, the WL450 provides a sleek, integrated appearance while maintaining the highest standards of performance. Available as a full sheath or as a one-sided version—which can be mounted on either side—it offers flexibility to suit different sauna layouts. Constructed from durable black-painted steel sheet, the WL450 is both functional and stylish. For complete protection, pair it with the matching Harvia WL100 Protective Bedding, which safeguards your floor while complementing the sheath’s modern look.
