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!
