BRULApor – the material for stove-building!

What actually is BRULApor?

BRULApor is a natural product made of clay obtained from open-cast mining, granulated into small balls then baked in a rotary kiln system at approx. 1200°C. The embedded organic materials burn and cause these balls of clay to expand. At the same time, the surface melts slightly and forms what is referred to as a 'sintered' outer skin. This gives rise to fine-grained and extremely light beads of clay with an aerated core and great compressive strength. This is what our BRULApor components are made of. Despite its light weight, these components are tremendously stable.

What does the use of BRULApor elements achieve for you?

Quite simply: time saving and at the same time a quantifiable financial benefit! That is because, with BRULApor, shapes can be created quickly, without the need for hours of work on building the masonry. You can get on with the job straight away without any messing around. The great selection of different round and angled shapes, platforms, coupling and round elements can now be created quickly, cleanly and cost-effectively. You save valuable working time and you spare your nerves.

What speaks in favour of BRULApor?

Series compressive strength

In DIN 4232, light concrete, the cube compressive strength of this porous material is sub-divided into strength classes. In blinding concrete, it is usually sufficient to have an average strength of 1–1.5 N/mm2.

Standard strength bWN of BRULApor (minimum value for the compression strength bWN of each cube) N/mm2: 4.0 (values in acc. with DIN 4232)

Thermal conductivity I in W/mk

BRULApor: 0.40 (in acc. with DIN 4108)

Coefficient of thermal conductivity K

BRULApor: 1.8 W/m2K


Your plus points

Mechanically and chemically resistant, i.e. neither acids nor lyes can attack BRULApor. Even in water, it remains neutral, it does not get mouldy or rot and it remains odour-free.

+ Fire resistant in acc. with TROL Para. 3.1 (in acc. with DIN 4102, fire rating A1)

+ dry and resistant to frost

+ dimensionally stable and environmentally compatible

+ suitable for structures in the platform area, masonry, skirts or as plaster-coated design elements

+ suitable for wet and dry cutting

+ less dirt and time saved during installation

+ Material is easy to process using a gas concrete saw

+ The rough surface provides a good grip for plaster.

+ On segment and round-arc platforms, a reinforcement grid is cast into the arc.

+ Compressive strength approx. 4.0 N/mm2 + dry density of 0.8
