Non-Combustible Insulation Solutions



Our non-combustible glasswool insulation solutions offer the best performance when it comes to both Reaction to Fire and Fire Resistance, enabling building designers and specifiers to develop effective and robust fire safety strategies when they design new buildings.

AS 1530.1 sets out a test method for determining the combustibility of building materials and is one of several test methods for evaluating the potential fire hazard of building products. This fire test was developed for use by those responsible for selection of construction materials.

Reaction to Fire

The measurement of how a material or system will contribute to fire development and spread, particularly in the very early stages of a fire, when evacuation is crucial.

Arguably, the most important test for product reaction to fire in Australia is determining combustibility by testing to AS 1530.1 - “methods for fire tests on building materials, components and structures combustibility test for materials.”

Upon completion of the test, the tested materials either deemed non-combustible or combustible. Non-combustible is defined as: “made of material that does not contribute as a fuel source to fire.” Testing is also carried out to determine the performance off materials in terms of fire behaviour, smoke production and full-scale system tests.

Our glasswool range has been tested and deemed non-combustible in compliance with AS 1530.1 criteria.

By choosing non-combustible insulation, building designers and specifiers can design out the risk of fire within the building fabric from the start. Using non-combustible insulation minimises the risk that the building fabric will contribute to the development of the fire or contribute to fire spread.

The measurement of the ability of a material or system to resist, and ideally prevent, the passage of fire from one distinct area to another.

Building Regulations require certain elements such as partitions, common walls between residences, mid-floors, external walls, ceilings and beam and column constructions requiring protection from fire.

Fire protection classifications are normally reported in terms of a period of fire resistance, for example, 60, 90 or 120 minutes. These classifications relate to three minimum criteria known as structural adequacy, integrity and insulation.

Simply, this means how elements — either in combination or individually — stop a fire spreading, how they restrict temperature rise and how the elements’ load-bearing capacity is maintained.

Knauf Australia has tested a broad range of systems for use in a variety of fire resistant applications, providing fire resistance periods ranging from 30 to 240 minutes to assist the design of safe buildings. These systems can be found in the Knauf Blueprint manual.

Our non-combustible, fire-resistant solutions help inhibit fire spread, maintain structural integrity and limit the spread of fire and smoke from one area to another, providing safe buildings for occupants, and added peace of mind for specifiers.
