Security Really Does Matter

Don’t compromise on your home security.

Break-ins don’t happen because burglars are clever. They happen because most windows are built to a price, not to a standard. Cheap hinges, thin glass, single-point locks: it takes seconds. We saw that in home after home across Tyne & Wear and County Durham, and we decided our windows would never leave a customer exposed. Every Full Security Window we fit is built to defeat the exact methods burglars use, and it’s tested independently to prove it.

“John explained the new safety feature that his windows have which makes them much more secure and really difficult for intruders to gain access. This makes me feel much safer.”

Our Window

Cannot be beat on security.

A window is only as secure as its weakest component. A great lock on a flimsy frame fails. A strong frame with removable glass fails. A reinforced hinge with a single-point lock fails. Our Full Security Window is engineered so that every component works as part of a system, and every component is independently tested to PAS 24, the UK enhanced-security standard specified by Secured by Design and required by Approved Document Q on all new-build homes. Most existing homes have none of it. Every window we fit has all of it.

01

Rehau Profile

The frame that everything else bolts to.

The profile is the skeleton of the window. If it flexes under attack, every lock, hinge and glazing clip fitted to it becomes easier to defeat. A cheap, thin-walled profile bows under a crowbar and lets the bolts pop out of the keeps. A rigid, reinforced profile holds every locking point exactly where it was engineered to sit, and the burglar walks away.

We build every Full Security Window on Rehau. Rehau is a German engineering company, founded in 1948, and their uPVC profiles are the most widely specified system in the UK for a reason: they are engineered to a higher tolerance than the mass-market alternatives, and their security testing is documented and independent. We are an Authorised Rehau Partner, which means the profile you get from us is the genuine article, not a cheaper look-alike.

Rehau profile installation

What that means in practice

  • Multi-chambered construction — Multiple internal air chambers inside the profile, each one adding rigidity and thermal insulation.
  • Steel reinforcement — Galvanised steel inserts run through the frame and sash, giving the profile the structural strength of a metal window with the thermal performance of uPVC.
  • PAS 24:2022 certified — Independently tested to the current UK enhanced security standard for windows.
  • BSI Kitemark to BS EN 12608 — Certified for material quality, weather resistance and dimensional stability. The Kitemark is only awarded after ongoing audit, not just one-off testing.
  • Secured by Design compatible — Meets the profile requirements of the UK police-backed crime prevention initiative.
  • A-rated as standard — Every Rehau window we fit achieves the highest BFRC energy rating.

The profile is where security starts. Get this wrong and nothing else you bolt to it does its job.

02

Multi-Point Shoot Bolt Locks

Eight steel bolts, one window, no single point of failure.

Standard casement windows are locked by a handle that operates two or three cam locks: small plastic or die-cast mushrooms that rotate into a keep on the frame. Burglars know exactly how to defeat them. A crowbar wedged next to the handle, a firm pull, and the cams either shear off or the profile flexes enough for them to slip past the keeps. It takes seconds and it's silent.

Our Full Security Windows are fitted with multi-point shoot bolt locks. Instead of two or three plastic cams, up to eight non-croppable steel bolts shoot out of the sash and into hardened keeps set into the frame. The bolts engage at multiple points around the sash, spreading any attack load across the full perimeter of the window rather than concentrating it at one weak point.

Multi-point shoot bolt locks

The technical spec

  • Up to 8 locking points per sash — More points, more force required, more time for the attack to fail.
  • Non-croppable design — Standard shoot bolts can be cut through the gap between sash and frame using long-nose bolt croppers. Non-croppable bolts are shaped so the tool can't grip them.
  • Tested to over 6,000 Newtons of force — More than double the load required to pass PAS 24. A burglar can't put 6,000N through a crowbar without the tool itself failing first.
  • Anti-separation on all three planes — Front-to-back, side-to-side, and up-and-down. Whichever direction the attack comes from, a bolt is holding the sash to the frame.
  • Adjustable mushroom cams — On top of the shoot bolts, providing additional anti-separation resistance and compression adjustment.
  • 50,000 cycle endurance tested — And 240-hour salt spray corrosion tested. The locks work on day one and they still work in year twenty.

Every bolt has to fail for the window to open. Not one, not two: every one.

03

Hinge Guards

Closing the gap burglars love.

Look at any window from outside when it's closed. You'll see a fine gap between the sash and the frame all the way around, including on the hinge side. That gap exists because the window has to open, and it's the point where almost every forced entry attack begins. A screwdriver, a small crowbar or the flat of a chisel goes into that gap on the hinge side and gets levered outward. Standard hinges are not engineered to resist that. Once the sash lifts off the hinge stubs by a few millimetres, the locks on the other side have nothing to hold against and the whole sash pops out.

Hinge guards close that gap mechanically. Every Full Security Window is fitted with anti-jemmy claw hinge guards: high-tensile steel brackets that lock the hinge side of the sash to the frame independently of the hinge itself. If a burglar tries to lever the sash away from the frame on the hinge side, the claw physically stops the sash from moving.

Hinge guards

The technical spec

  • PAS 24 certified — As part of a full window assembly.
  • High-tensile steel construction — Corrosion-resistant finish, engineered specifically for uPVC profiles.
  • Face-fixed to frame and sash — Creating a mechanical anchor that operates independently of the hinge.
  • Works even if the hinge itself is defeated — A burglar could theoretically break the hinge and still not be able to separate the sash from the frame.
  • Invisible when the window is closed — No aesthetic compromise, no visible hardware, no signal to the outside world that the window is protected.

Most window companies rely on the hinge to hold the hinge side of the sash to the frame. We don't. We assume the hinge might fail, and we build in a second line of defence that operates independently.

Is your hinge side exposed?

Most existing windows have no hinge protection at all. Book a free survey and we'll assess every vulnerable point in your home.

04

GT Snap-Lok Glass Retention

Because the glass is easier to remove than the locks.

Here is a technique most homeowners have never heard of, and every experienced burglar has. On a standard uPVC window, the glass is held in place by a plastic beading strip clipped around the inside of the sash. Attack that beading from outside with a chisel and it lifts off. The whole sealed glass unit can then be pushed inward, taken out cleanly, and the burglar climbs through the empty frame. The locks are still locked. The hinges are still intact. The window was never forced. And the intruder is inside your home.

GT Snap-Loks are what stop that. GT Window Products is a specialist UK manufacturer of window security components, based in the UK since 1993, and their Snap-Lok system is the industry benchmark for glass retention. Every Full Security Window we fit has multiple Snap-Loks fitted between the sash and the sealed glass unit. If the external beading is removed, the Snap-Loks hold the glass in place. It cannot be pushed inward and it cannot be pulled outward.

GT Snap-Lok glass retention

The technical spec

  • PAS 24 certified glass and bead retention system — Formally part of the PAS 24 test assembly, not an aftermarket add-on.
  • High-tensile steel construction — Not plastic, not thin metal, not the kind of clip you can bend by hand.
  • 240-hour salt spray corrosion tested — UK weather rated, will not corrode or weaken over the life of the window.
  • Fitted at multiple points around every opening sash — Minimum four per unit, more on larger sashes, in a diamond or corner formation for maximum resistance.
  • Made in the UK — By a specialist window security manufacturer since 1993. Not a generic import.

If a burglar removes your beading and the glass falls into their hands, your window was never truly secure. Every Full Security Window we fit is engineered so that doesn't happen.

Think your glass can't be lifted out?

Most standard windows are vulnerable to this exact method. Book a free survey and we'll show you whether yours are at risk.

05

Secure Glazing Bracket

Our own invention. A second line of glass retention.

The Snap-Lok is the industry-standard answer to glass removal, and it works. But we saw it working and asked a simple question: what if we added a second, completely independent system doing the same job from a different angle? A burglar defeating one glass retention system is unlikely. A burglar defeating two, fitted in different places on the same window, using different mechanical principles: that is what we set out to make impossible.

The result is our patent-pending secure glazing bracket. Developed and tested by our own glazing specialists here in the North East, the bracket is fitted internally alongside the Snap-Loks and adds a further mechanical anchor between the sealed glass unit and the frame. It's a belt-and-braces approach: two independent glass retention systems on every window, from two different manufacturers, using two different fixing methods.

What it does

  • Fitted internally — Completely invisible from the outside.
  • Reinforces the anchor between the sealed unit and the profile — Working in combination with the GT Snap-Lok for two-system glass retention.
  • Compatible with uPVC and timber window profiles
  • Available on every new J&J Hunter Brothers installation as standard
  • Available as a retrofit to existing windows — Following a compatibility check on site.
  • Patent pending — Developed by the family that fits it.

John explained the best windows, including the partnership with Secure Windows Solutions, bringing together a new secure feature that no other company has. This security bracket prevents the window's glass panes from being removed and ensures a further level of security for my home.

06

Laminated Glass on Low-Level Glazing

The glass that holds together when everything else says it should have broken.

Even with every lock, hinge guard and glass retention system in place, a determined burglar's last resort is to break the glass and reach through. On standard toughened glass, that works: one firm strike with a hard object and the entire pane shatters into small pebbles, leaving a clear opening. The noise is brief and the entry is instant.

Laminated glass changes that outcome. Every Full Security Window includes laminated safety glass as standard on every low-level opening: any pane within reach from ground level, garden furniture, a bin, a wall, or any other climbable feature. Two panes of float glass are bonded together with a tough plastic interlayer (PVB), and when the outer pane is struck, the interlayer holds every fragment of glass in place. The glass cracks, but it does not fall out. There is no clean opening, no reachable hole, and no fast entry.

Laminated glass security glazing

The technical spec

  • BS EN 356 Class P1A certified as standard — The same security glazing rating required by Approved Document Q for the front doors of new-build homes across England.
  • 6.4mm laminated construction — Two 3mm float panes plus PVB interlayer as standard, with a P2A upgrade available in 6.8mm for even higher impact resistance.
  • Same construction used in car windscreens — Anyone who has seen a smashed windscreen knows: it cracks, it webs, but it does not fall out. That is the property we want on your ground-floor windows.
  • 99% UV filtration — The interlayer blocks almost all ultraviolet light, protecting carpets, curtains and furniture from fading.
  • Acoustic damping — The interlayer significantly reduces external noise: traffic, wind, neighbours.
  • Meets the glazing element of Approved Document Q — The security requirement placed on all new-build homes in England since October 2015. Most existing homes have never had glass of this specification fitted.

Laminated glass buys the one thing every intruder is short of: time. Time for a neighbour to hear. Time for an alarm to trigger. Time for the intruder to give up and walk away.

Independently Tested

Every Full Security Window meets or exceeds the standards specified by:

PAS 24:2022

The UK enhanced security performance standard for windows and doors. Tests physical attack including forced entry, lock manipulation, and frame separation.

Approved Document Q

The Building Regulations security requirement for new-build homes in England since October 2015. Most existing homes were built before it applied.

Secured by Design

The UK police-backed crime prevention initiative. Requires PAS 24 as its minimum entry point.

BS EN 356

The European standard for security glazing, testing glass resistance to manual attack.

Optional Full-Window Glazing Upgrade

Enhance every pane with laminated glass.

Every Full Security Window comes with laminated glass fitted as standard on low-level openings: the panes an intruder can actually reach. For customers who want the same protection on every window in the house, upstairs and downstairs, we offer a full laminated glass upgrade across the whole installation. Same construction that goes in car windscreens and shopfront glazing. Same construction specified for the front doors of new-build homes under Approved Document Q. It changes the way a window fails under attack.

Laminated glass is two panes of float glass bonded by a tough polyvinyl butyral (PVB) interlayer. When the outer pane is struck, the glass cracks but the interlayer holds every fragment in place. There is no clean hole to reach through, no easy opening to climb into, and the noise of repeated attacks draws attention long before entry becomes possible. Standard toughened glass, by contrast, drops out of the frame in a single hit and leaves a clear opening.

Laminated glass upgrade

Holds Together on Impact

The PVB interlayer keeps the glass in one piece even when broken. No hole to climb through, no glass on the floor inside.

BS EN 356 Certified

Independently tested to the European standard for security glazing. Class P1A as standard, P2A available on request.

Blocks 99% UV

The interlayer filters almost all ultraviolet light, protecting your carpets, curtains and furniture from fading.

Quieter Home

The interlayer also damps sound. Noticeably less traffic, wind and neighbour noise on every laminated window.

Where it makes the biggest difference

  • Ground floor and low-level windowsIncluded as standard on every Full Security Window.
  • Bedroom and side-return windowsAnywhere accessible from a flat roof, a garage roof, a bin store or a boundary wall.
  • Rear-of-property windowsOut of sight from the street, historically the most targeted area of any home.
  • Skylights and roof windowsOverhead glass that has to hold together for safety as well as security.

Full Security Windows FAQs

Standard windows are usually built around a single lock and a single pane of glass. Our Full Security Window combines six layers of protection: PAS 24 certified Rehau profile, 8-point shoot bolt locks, PAS 24 hinge guards, GT Snap-Lok glass retention, our patent-pending secure glazing bracket, and laminated glass on low-level openings. Every layer targets a specific method burglars use to force entry, and the combined specification meets or exceeds the security requirements Approved Document Q places on new-build homes.

Yes, though some security features are included as standard in our window installations. Book a free survey and we'll walk you through exactly what's included and what the full security specification costs for your home.

The patent-pending secure glazing bracket and laminated glass re-glazing can be retrofitted to most existing uPVC and timber windows. The full window specification, including the Rehau profile and multi-point locking, requires a new installation. We'll confirm what's possible for your home during a free survey.

No. From the outside, a Full Security Window looks identical to any other quality uPVC window. It opens, closes, and cleans exactly the same. The security is engineered into the frame, hinges, locks, and glass, not bolted onto the outside.
