EN 356

Glass in building - Security glazing - Testing and classification of resistance against manual attack.

Alongside our Bullet Resistant products Architectural Armour can offer an alternative; Security Glass, Windows and other Products.  The BS EN356 standard specifies requirements and test methods for security glazing designed to resist actions of forced or manual attack or attack resistant.

To view the products that can incorporate EN 356, manual attack resistant glass, see the below links.

Lower Resistance Level

The test standards has two test parameters; higher and lower resistance.  The lower resistance sees glass undergo impact from steel balls dropped from differing heights in a triangular formation.  This test covers the glass rated from P1A to P5A.  P1A the balls are dropped from the lowest height, P5A 3 sets of 3 balls are dropped from a height of 9 metres.  

Higher Resistance Level

The higher resistance level is tested with multiple strikes of a hammer and axe.  The glass is held in a frame and subjected to strikes in a certain area by a mechanical hammer and axe ensuring the force is controlled throughout.  This standard covers P6B to P8B.  These products are available in laminated all glass constructions or glass/polycarbonate/glass constructions giving you a range of thicknesses to choose from.

The product can be provided as single laminated pane or incorporated into double glazed units (DGUs/IGUs) for use internally and externally.  They can offer an extra level of protection in domestic or commercial properties.

The EN356 glass is commonly used in Jewellery store applications, for use as front of store or display cases/windows.  The glass prevents smash and grab attempts from being successful; delaying the intruders attack giving the police vital minutes to respond.

We also utilise this glass in our SW1&2 Transaction Windows and our external transaction window,  similar to a BSW but incorporating EN356 glazing instead.
