Fire Walls

Concrete Barrier Block Fire Walls

We use Stacablocs for the construction of concrete barrier block fire walls because they are wider than Virtabloc and allow the wall to be built higher.

We use our Geo concrete mix as the geopolymer characteristics perform better in very high temperatures. In general terms concrete does not burn and can protect other structures from fires caused by inflammatory materials such as tyres, chemicals, fuels any many other materials.

  • Class A1 fire resistant

    Class A1 fire resistant in accordance with clause 4.3.4.4 of EN 13369.

    Concrete does not burn and therefore cannot contribute to a breakout and the spread of fire or add to the fire load.  As concrete cannot burn it does not emit smoke, gases or any toxic fumes when affected by fire.

    All building materials have been classified in terms of their reaction to fire and their resistance to fire, which will determine whether or not a material can be used and when additional fire protection needs to be applied to it. Based on the European Construction Products Directive, EN 13501–1: 2002: Fire classification of construction products and building elements classifies materials into seven grades with the designations, A1, A2, B, C, D, E and F, according to their reaction to fire.

  • Concrete Block Fire Walls, Class A Fire Resistant Concrete Walls

The highest possible designation is A1 (non-combustible materials) and the European Commission has published a binding list of approved materials for this classification, which includes the various types of concrete and also the mineral constituent materials of concrete. Concrete fulfils the requirements of class A1 because its mineral constituents are effectively non-combustible (i.e. do not ignite at the temperatures that normally occur in fire).

A1 Fire ResistantConcrete is a very effective fire shield. The mass of concrete confers a high heat storage capacity. Also its porous structure provides a low rate of temperature rise across a section. These properties result in a low rate of temperature rise that enables concrete to act as an effective fire shield.

Due to the low rate of increase of temperature through the cross section of a concrete element, internal zones do not reach the same high temperatures as a surface exposed to flames.

Even after a prolonged period, the internal temperature of concrete remains relatively low; this enables it to retain structural capacity and fire shielding properties as a separating element.
