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.

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.

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.

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.

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.
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.

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.
