What is Siderise Lamella?

Get to know our unique, revolutionary cavity  barrier and firestop insulation technology

Always on top form

There are several types of cavity fire barrier solutions available, for different kinds of applications. It is vital that these safety-critical products not only deliver the fire performance necessary, but that they can also achieve and maintain good form and fit for the lifetime of a system, even when subjected to building movement

In 1991, Siderise founder, Steve Bond, developed an automated ‘high speed lamella’ process to create products that could do just that.

What makes Siderise Lamella unique?

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.

Why is Lamella used in Siderise products?

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.

Siderise Lamella around the world

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.

Innovation at our core

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