SIRO Unique Chimney
A chimney that seamlessly combines safety and style.
The industry's most advanced insulation structure allows for a slim outer diameter while minimizing the required safety clearance.
This allows greater freedom in fireplace placement and allows the chimney to pass safely even through the tightest spaces.
The insulation structure combines the best qualities of two top-tier insulating materials.
Passes through structures requiring 30% less space than competing products.
Slim exterior diameter (starting at 238 mm)
Passes through even tight spaces.
The insulation design of Siro Unique is the result of extensive product development. Unlike traditional chimneys, it features two insulation materials: a layer of heat-resistant silicate protects the mineral wool, helping it retain its excellent insulating properties even in extreme temperatures.
The result is an exceptionally safe and durable chimney without any increase to its circumference, and with minimal safety clearance requirements.
