Fire iconFire Resistant Windows

Architectural Armour offer fire resistant,  attack / fire, blast/fire and and bullet/ fire resistant windows,  below is a small glossary of the terminology, please contact us to discuss your specific requirements . Please email mailto:info@architecturalarmour.com or call +44(0) 1981 25700 

Intergrity  E

This is the ability of glazed material to prevent the spreading of flames or hot gases (integrity), denoted by the symbol E, e.g. E30, E60, E90 or E120

Insulation  EI

Insulation is the ability of a glazed material to limit heat transfer to the unexposed surface (integrity and insulation), denoted by the symol E, e.g. EI30 , EI60 but may be expressed as fire glass 30/30, 60/60  or 120/120. 

Duration 

This is the period of time a glazed material can peform and defines the classifications for fire resistance, typically 30, 60, 90,, 120 .  e.g.

E60 is a Integrity only glass offering 60 minutes .

EI60 is an integrity and insulation product offering 60 minutes.

Dual Purpose 

Fire glass can either be bonded onto a laminate or incorporated into a double glazed unit for thermal efficiency or for greater security combined with bullet or physical attack glass. 

Ballistic and Fire 

Where the need for protection against bullets as well as fire arises, Architectural Armour can offer a variety of ballistic glazed options to suit the following EN1063ballistic protection levels. Please click through to specific details of the glass used in these windows.

EN 1063BR2 / EN1522/3 FB2,  E30 & E60

EN1063 BR3 / EN1522/3 FB4,  E30 & E60

EN1063 BR4 / EN1522/3 FB4,  E30 & E60

EN1063 BR5 / EN1522/3 FB5,  E30 & E60

EN1063 BR6 / EN1522/3 FB6,  E30 & E60

EN1063 SG1 &2 / EN1522/3 FSG,  E30 & E60 

Physical Attack and Fire 

Similar to the above ballistic protection the fire glass can be offered to meet the EN356 physical attack standards.  Most popular are 

EN356 P6B,  E30 & E60 

EN356 P7B,  E30 & E60

EN356 P8B,  E30 & E60

Double Glazed Unit (Thermal)

Thermal insulation is often a requirement in primary glazing, by incorporating a certified Fire Glass into a Double Glazed Unit DGU (also known as Insulated Glass Unit, IGU) this can be achieved.

Varying the depth of spacer bar and void infill, these DGU's can achieve a range of U Values.  On a standard unit the cavity between panes of glass will be filled with air, the air can be replaced with argon which is an inert gas to improve its thermal performance.

Sulphur hexafluoride infill is available for improved acoustic performance. 

Certification

Each fire glass sold on the market is tested and issued a Certifire Document, outlining the test parameters and the results/conclusion obtained.  In the document it will also specify the framing requirements to achieve the rating, i.e. to achieve E30, meaning 30 minutes protection against flame, you need a glass such as a modified toughened 6mm and this can then be framed into either a timber construction or a specified steel profile including Jansen Economy.  There will also be restrictions on maximum pane sizes for windows and vision panels etc but this is all outlined quite clearly in the Certifire Document readily available from the manufacturers of the glass.  An example of such a document is noted below

 

This quite clearly notes the maximum pane sizes for a window into a steel profile system and gives option for the type of frame used.
