What makes the multi-insulation structure so special?

 

Typically, chimneys only feature one insulation layer between the inner and outer surfaces, utilizing either mineral wool or ceramic insulation. Neither of these alone is usually sufficient to ensure safety. 

 

In Siro Unique, the best features of mineral wool and ceramic insulation come together in a cleverly designed structure, featuring five walls instead of the traditional three. This innovative design ensures safety by maintaining a safe temperature on the outer surface of the chimney.

Frequently Asked Questions

 

When should I choose Siro Unique?

Siro Unique is an exceptionally safe chimney suitable for all types of fireplaces. It is especially well-suited for situations where a slimmer profile and small safety distances are required without compromising on safety. Siro Unique is an ideal choice for small fireplaces, glass-enclosed terraces, or confined spaces. Specially designed accessories ensure a safe and easy installation. With its slim outer diameter and safe insulation structure, Siro Unique is also suitable for use as a stove chimney.

 

When you want improved safety more cost-effectively, choose Siro Prime.
If there is no separate combustion air duct for the fireplace, choose Siro Air – our makeup air chimney.
Looking for a chimney for a wood-burning sauna? You can also choose the air-cooled Siro Air Sauna stove chimney.

 

What makes Siro Unique so safe?

Traditionally, chimneys have a three-wall structure with one insulation layer consisting of either mineral wool or ceramic insulation. Used alone, neither of these materials is usually sufficient to guarantee safety.

In Siro Unique, the best features of mineral wool and ceramic insulation are cleverly combined in a smartly designed structure with five walls instead of three. The outer surface of the chimney always remains at a safe temperature.

 

Can I install Siro Unique to replace an old chimney?

Yes, you can. The accessories for Siro chimneys make retrofitting easier than usual, so you can easily replace the old chimney with a safer one. You can also install Siro Unique, for example, inside an old masonry chimney.

 

Is Siro Unique compatible with my fireplace?

Siro Unique is suitable for fireplaces with flue duct sizes of 150, 175, 200, or 250 mm. You can easily find the Siro Unique solution that fits your specific fireplace, including module diameters and quantities, by contacting us ›
