Bradford Thermofoil comprises a range ofaluminium foil laminates available in various CSR Bradford Insulation products are tested tomeet stringent quality control standards incorporatingquality management systems such as AS3902 Insulation has a 65 year history of providinginsulation for fire PROTECTION applications. Bradford scomprehensive fire testing research laboratory in Sydney,Australia is registered by the National Australian TestingAuthority (NATA) and, in conjunction with theAustralian Government s Commonwealth Scientific andIndustrial Research Organisation (CSIRO), is able toundertake fire testing to meet many THIS purpose of the guide is to provide informationon the benefits from the use of Insulation materials in thefire PROTECTION of buildings, industrial processes, shipsand other applications. The incorporation of the correctinsulation products in the design of passive fire protectionsystems can save lives and complement the installation ofactive fire PROTECTION equipment.

3 In most countries the inclusion of fire rated buildingproducts such as Insulation is covered by strict buildingcodes or other fire safety regulations. Information isprovided in this guide to assist the designer in the correctchoice of Insulation to meet these stringent fire range of Bradford products and their applicationsis presented along with data and worked examples toillustrate design considerations. Sample specifications forapplications are also included. In order that the benefitsof Insulation may be realised most cost effectively, it sinclusion in passive fire PROTECTION systems should beconsidered from the initial stage of design. Information included in this Design Guide relates toproducts as manufactured at the date of publication. Asthe CSR Bradford Insulation policy is one of continualproduct improvement, technical details as published aresubject to change without notice. Similarly, regional fireregulations referenced in this guide may also change overtime, and current information should be obtained at thedesign assist designers, a free and comprehensive technicalservice, as well as advice and assistance in specifying andusing Bradford products is available from CSR BradfordInsulation offices in your region.

These regulations and codeshave been developed around the world from the tragic experiences of real fires resulting in loss oflife or property. Investigations by fire fighters and government fire authorities have led to requirementsthat the use of fire rated building materials should be included in designs, particularly in high firerisk environments. Whilst many countries are now moving away from prescriptive to performance based regulations,the principle objective remains that of minimising the spread of flames and the release of toxic fumesfrom fires to ensure occupants have sufficient time to safely escape the inferno. Rockwool mineral fibre Insulation , in particular, has achieved widespread international use as alightweight, adaptable and effective fire rated building product for use in passive fire PROTECTION fire PROTECTION is a term which describes materials that are an integral part of theconstruction of a building.

Firegrowth is a function of the fuel itself, with little or noinfluence from the configuration of a building. Givensufficient fuel and oxygen, fire will continue to growresulting in an increase in compartment substantial heat is generated, over 500 600degrees Celsius, flashover occurs and the fire becomesfully developed, engulfing the whole compartment.

This areacan be a single room, a series of rooms or an entire can also be a vertical shaft for services or a crawl spacebeneath a large proportion of fires do not spread beyond thecompartment of origin. Therefore, if careful attention todetail is placed on compartment design fire losses shouldbe in a compartment can be controlled by eitherpassive or active fire PROTECTION measures.
