Which glass would I need to use to satisfy a specific fire rating?

Pilkington Specifire incorporates all the information you need to choose the right product for your application. We recommend that you check with your local authority to see which level of fire resistance is applicable for your project. 

Fire resistance is defined in BS 476: Part 20: 1987 as the ability of an element of building construction to withstand exposure to a standard temperature, time and pressure regime without loss of its fire separating function or load bearing function or both for a given time.

Integrity
Is defined in BS 476: Part 20: 1987 as, "The ability of a specimen of a separating element to contain a fire to specified criteria of collapse, freedom from holes, cracks and fissures and sustained flaming on the unexposed face.  
 
Insulation
Is defined in BS 476: Part 20: 1987 as, "The ability of a specimen of a separating element to restrict the temperature rise of the unexposed face to below specified levels". This requires, in a test, that the unexposed face rises on average by no more than 140°C and in any single position by no more than 180°C
