What is Siderise Lamella?

Siderise’s lamella features a special formulation of stone wool insulation with vertically oriented fibres, rather than the horizontal fibres traditionally used.

These fibres are laterally compressed under quality-controlled factory conditions using our unique manufacturing process to assist with uniform density and remove any gaps between the adjoining cut sections, which may result in weakness. This ‘pre-compression’ is held in place by a carrier (typically foil)  facing that is heat applied to the cut faces of the fibres. This also provides weather protection without the need for a wet sealant.

The result is a structurally sound and long-lasting fire barrier solution that can withstand building movement and is much simpler and quicker to install than traditional approaches.

As accelerated age testing in accordance with EOTA Technical Report 024 demonstrates, the vertical fibre structure of Siderise Lamella allows our products to be laterally compressed repeatedly, with no loss of recovery / flex. This gives them the ability to accommodate in-service movement, allowing the integrity of seal within the gap to be constantly maintained, ensuring effective fire compartmentation and sound control for the lifetime of the building.

The video below shows this in action.
 

Our manufactured products with the vertical fibre structure and unique pre-compression provide a combination of installation and performance benefits on a wide variety of façade types— including curtain wall, rainscreen and masonry. These products have also gone through decades of third-party testing to ensure market leading performance. This integrity in our product performance plays a significant role in revolutionising how we protect the high-rise buildings which define the world’s skylines.

To this day, we are using our in-depth knowledge of passive fire protection to develop new solutions and approaches.
