Cost-Effective Safety

 

The chimney’s simplified structure allows better safety more cost-effectively.

Siro Prime Chimney

 

The most advanced mineral wool insulation packed into the highest-quality steel jacket: Siro Prime is our most cost-effective solution for the safe extraction of smoke from the fireplace. It features a new type of mineral wool insulation, which maintains its safety even in extreme temperatures (up to 1150 °C). This enhances the safety of the chimney without increasing its circumference.

 

Fiberized insulation – exceptional insulation capacity

Typically, the phenomenal insulation capability of mineral wool is lost during the manufacturing process. Siro Prime's insulation is produced by fiberizing the mineral wool into a tubular shape, preserving its insulation capacity.

 

Less binder – better insulation, less odour

Binder is a poor heat insulator and evaporates over time. This is why there is less of it in Siro Prime. A lower binder content also means that the typical odors associated with mineral wool insulation have been eliminated.

Frequently Asked Questions

 

When should I choose Siro Prime?

When you want better fire safety cost-effectively, Siro Prime is the best choice. Because Siro Prime enables cost-effective implementation of customized solutions, it is particularly popular in industrial settings. Choose Prime when the fireplace and chimney system can be implemented with a minimum clearance of 110 mm. Specially designed accessories ensure a safe installation.

 

When the chimney needs to pass through a tight space or you need an especially sleek solution, choose Siro Unique ›

When there is no separate replacement air duct for the fireplace, choose Siro Air makeup air chimney ›

When you need a chimney for a wood-fired sauna, choose the cooling Siro Air Sauna stove chimney ›

 

What makes Siro Prime's mineral wool insulation so special?

The secret of Siro Prime's insulation lies in its unique manufacturing process. Traditionally, mineral wool insulation is made by sawing a piece from an insulation sheet. When the surface breaks, the fibers snap, and air pockets disintegrate, no longer providing optimal insulation. Additionally, traditional mineral wool insulation uses a significant amount of binder, causing odors and, when evaporating, diminishing insulation capacity over time.

 

Siro Prime features an entirely new mineral wool insulation. It is pre-shaped into a tubular form, maintaining a unified structure for better insulation. The low binder content ensures pleasant use and preserves insulation safety over the long term.

 

Is Siro Prime compatible with my fireplace?

Siro Prime is suitable for fireplaces with flue sizes of 150, 175, 200, 250, or 300 mm. If you need help with finding the right Siro solution for you, please do not hesitate to contact us!
