Safer

Meet the highest security standards

Our industry-leading security secondary glazing products protect valuable property and precious lives against intruders, attackers, bomb blasts, bullets and fire.

 

Be on the safe side

Perhaps you want resident peace of mind or lower insurance premiums. Or are you looking to fulfil your Duty of Care (particularly Martyn’s Law)?  It’s a good idea to involve risk assessors, blast engineers, counter-terrorism experts and Designing Out Crime Officers to make sure the protection level you choose isn’t unnecessarily high – or leave you vulnerable. While we can’t advise on the standard of security you’ll need, we can certainly advise on what product will meet the required standard and the overall project brief. We can also assure you that our secondary glazing will provide the most discreet and sympathetic window security treatment. Contact us  

Safe from intruders

Tested to their limits, our windows, frames and locks protect against stealth attacks, forced entry and attempted assaults. They deter criminals, protect against a range of tools and weapons – and buy occupants life-saving escape time.

BS EN 356: 2000

This 8-category European standard measures resistance of glass to a sustained attack. This is simulated by a 4.11kg ball drop (P1A-P5A) and a mechanical axe strike (P6B-P8B). Glass thickness will also vary.
Category of Resistance Drop Height (mm) Total Number of Strikes Code Designation of Resistance Class 
P1A 1500 3 in a triangle BS EN 356 P1A
P2A 3000 3 in a triangle BS EN 356 P2A
P3A 6000 3 in a triangle BS EN 356 P3A ​
P4A 9000 3 in a triangle BS EN 356 P4A ​
P5A 9000 3 x 3 in a triangle BS EN 356 P5A 
P6B N/A From 30 to 50 BS EN 356 P6B 
P7B N/A From 51 to 70 BS EN 356 P7B 
P8B N/A More than 70 BS EN 356 P8B 

PAS24 and Secured by Design

Withstanding screwdrivers, crowbars and more, our PAS-accredited products deter stealth attacks. For added peace of mind, they’ve also achieved a Secured by Design ‘Police Preferred Specification’. This a recognised standard for all security products that can deter and reduce crime. S80 HS S25 VS S90 VS S41 HC S45 HC S40 FL S46 FL

LPS 1673 – a world first in windows

We are the only glazing company to meet this latest security standard. LPS 1673 draws on extensive research by the UK government’s National Protective Security Authority (NPSA), which advises on physical and personnel protective security. Ratings are measured in terms of attack weapon – from knives to sledgehammers – as well as the minimum length in seconds the window can withstand that attack.

LPS 1175

The highest available physical security standard. Unlike LPS 1673, products are designed to prevent and deter forced entry with easily concealed tools.

Safe from bomb blasts

Protect people and property from flying glass shards caused by a nearby explosion. Special frames, fixings and locks are created to absorb and spread the load. Laminated glass stretches and stays intact.

ISO 16933:2007

To pass this test, our products are subjected to a simulated car bomb attack – the equivalent of 100Kg TNT, detonated at distances between 15m and 45m from the target. Classification codes are EXV(X). EXV is a vehicle bomb and X is the distance from the explosion in metres.

Safe from bullets

Reinforced steel frames combine with unexpectedly light glass laminated with polycarbonate to protect high-profile targets.

EN 1522/1523

This standard applies to all bulletproof windows, doors, shutters and blinds. There are eight levels of classification, covering rifles, shotguns and handguns like the .44 Rem Magnum. S55 DFL

Safe from fire

Fire resistant secondary glazing can help protect windows near fire escapes, or in laboratories and testing facilities, allowing for precious evacuation time.

BSEN 1363-1: 1999, BSEN 1364-1 :1997

This is a fire resistance test. To achieve accreditation, our products must maintain their integrity for at least 30 minutes in the face of fire. S55 DFL
