The problem
Protecting staff without closing the counter
- 01
Staff exposed at the counter
Frontline staff meet the public face to face, sometimes in the worst moment of that person’s day.
- 02
Protection that kills the conversation
A screen that blocks sound makes every exchange harder. Speech transfer keeps the counter usable.
- 03
Counters that do not fit
Buildings are rarely standard. We measure the opening and make the screen to fit it.
- 04
The wrong level of protection
Over-specify and you pay for glass you do not need. Under-specify and it is decoration. The rating should follow a risk assessment.

Guide
Designing a secure counter
A good counter protects staff without holding the public at arm's length. The glass is only part of that. The frame, the fitting, and how people talk and pass things through matter as much.

Where counter screens are used
Reception and enquiry windows, cash and ticket offices, administrative service desks, healthcare surgeries and dispensary counters, and government counters such as licensing and tax offices. Custody areas and interview rooms need the highest levels of resistance.
- 02
Choosing the level of protection
Start with the risk assessment, then the practicalities: what crosses the counter, how staff and customers need to talk, accessibility needs, the space available and what it has to work with. That order stops you paying for glass you do not need, or fitting glass that is not enough.
- 03
How the screens are built
Frames are welded mild steel with a polyester powder-coated finish. Bullet-resistant glazing is built up from layers of toughened glass and polycarbonate, which absorb the impact and reduce spall, the fragments thrown off the protected side.
- 04
Talking through the glass
Speech passes through the mullions in the screen, so conversations work without raised voices. In busy or noisy places, electronic speech enhancement can be added, and bullet-resistant pay windows can include an induction loop for customers who use hearing aids.
- 05
Fitting it to your space
Screens can go onto an existing counter, into a prepared opening, or be joined with doors, hatches and transfer trays into a longer protected line.
- 06
Windows as well as counters
Windows are often the weakest point in a building. Window security screens can be made to forced-entry resistance ratings, keep sightlines and natural light, fit existing frames, and include ventilation or emergency escape where regulations require it.
- 07
Screens and cameras together
A screen stops an attack; a camera records it. Paired, the counter is protected and anything that happens at it is on record, which also helps settle disputes and health and safety questions.
Are screens made to measure?
Yes. Screens, counters and pay windows are fabricated to size in our Edenbridge workshop, so we measure up at survey.
What's the difference between EN356 and EN1063?
EN356 rates resistance to manual attack, such as hammers or axes. EN1063 rates bullet resistance. Most counters are specified to EN356; EN1063 is for sites where a risk assessment identifies a firearms threat.
Are bulletproof screens the same as bullet-resistant screens?
Yes. Bulletproof is the everyday name, but no glass stops every round, so screens are rated by the threat they are tested against: EN 1063 classes such as BR4 for firearms, and EN 356 classes such as P4A for manual attack. Tell us the risk and we will specify the rating.
Will staff and visitors still hear each other?
Yes. Speech passes through the mullions in the screen, and electronic speech enhancement can be added where it is noisy.
Can you fit to our existing counter?
Yes. Screens can sit on a counter you already have, or go into a prepared opening.
Can a counter include a hearing loop?
Yes. Our bullet-resistant pay windows can include induction loop technology alongside electronic speech enhancement, so staff can serve customers who use hearing aids.
Why MerFen
One firm makes it, fits it and keeps it working
Most installers fit what a manufacturer sells them. We make the physical side ourselves, so the specification starts with the site.

Made in our own workshop
Screens, counters, doors, gates and hatches are fabricated in Edenbridge, to the sizes the building actually has.
- One team
Nobody passes the job on
The same people survey the site, draw the specification, make the steel, fit it and come back to service it.
- Approved
Accredited and partnered
SafeContractor accredited, with Hikvision VASP, Axis, Hanwha Vision and Paxton partner status behind the electronic side.
- After handover
Covered once it is in
Twelve months on our installation, three years on Hikvision hardware, and annual service contracts for the systems we install.
