		+	Fire occurs as a result of a series of very rapid chemical reactions between a fuel and oxygen that releases heat and light. For combustion to occur, oxygen, heat and a fuel source must all be present; this is the ‘fire triangle’. Flames are the visible manifestation of combustion.

	Fire insulation (or more usually fire-rated or fire-resistant insulation) is a term that covers insulation materials which have insulative properties but are also non-combustible or have limited combustibility.

Fire insulation (or more usually fire-rated or fire-resistant insulation) is a term that covers insulation materials which have insulative properties but are also non-combustible or have limited combustibility. As passive fire protection elements, they do not need to be activated to provide fire resistance and hence can help prevent the spread of flame between spaces and components within and between buildings.

By slowing the spread of flame, such materials can protect the structure, allowing people valuable time to escape the building; they can therefore play a huge part in saving lives and protecting investments.

A typical example is stone wool insulation which can be non-combustible. Other types of insulation that may provide fire resistance include mineral wool, fibreglass and cellulose-based wool insulation. Sheep’s wool is regarded as a sustainable solution but must first be treated to make it more fire resistant. Some of these products are available in blankets (supplied in rolls) and/or rigid slabs.

Fire-rated insulation in a building can be used in a number of places, including in:

* Cladding;
* Floors and ceilings;
* Roofs;
* On structural steel;
* Cavity barriers and firestopping;
* HVAC applications

In addition to its fire-resisting properties, the insulation used in the above applications may also provide acoustic and thermal insulation.

Part B of the Building regulations determines the fire performance of buildings. For a fire-rated insulation to be used in a building it must pass certain British Standard (BS) tests: products are classified according to how they perform in the tests, enabling specifiers and contractors to choose the best fire-rated insulation for a given application.

* BS 476-1: Fire tests on building materials and structures, and
* BS EN 13501-1:2018: Fire classification of construction products and building elements (Classification using test data from reaction to fire tests).
