What to think about for hermetic sliding doors in Derry/Londonderry
- Labs and cleanrooms in Derry/Londonderry often have modular wall panels. Frame details must match the panel system, so involve the cleanroom contractor before the door is ordered.
- Infection control rules in hospitals across County Londonderry usually require screening, dust control and permits for work in clinical areas. Share your procedures at survey so they are built into the programme.
- Interlocked doors need clear logic. Decide with your engineers which door has priority, how staff override the interlock in an emergency and what the status lights should show.
- The floor must be flat and continuous through the opening. Welded vinyl or resin floors should be completed or repaired before the door is fitted, so the bottom seal meets a true surface.
- Pharmacy aseptic units in Derry/Londonderry may want doors that follow the colour coding of their clean zones. Leaf finishes can be chosen in a different colour for each grade of room.

Standards and rules in Northern Ireland
BS EN 16005 is the current standard for the safety in use of powered pedestrian doors, and BS 7036-0:2014 is the British code of practice for risk assessment and risk reduction used alongside it. Standards are not law in themselves, but they are the recognised benchmark for showing an automatic door is safe to use, and we set up, test and document doors with reference to them.
Glass in and beside doors must limit the risk of injury where people could walk into it, and clear glass must incorporate features that make it apparent (Building Regulations (Northern Ireland) 2012, Part V).
How it works
- Send photos and the address. A few pictures of the door from both sides, the address in Derry/Londonderry and a note of who uses the entrance help us understand the job before anyone visits the site.
- No-cost survey on site. We arrange a survey at a time that suits the building. The engineer records measurements, fixings and power, plus any constraints such as listed status, opening hours or access for deliveries.
- Itemised quote to approve. We price every element of the work on hermetic sliding doors separately in a written quote that you can check, share and approve. Lead time and payment stages are stated, and nothing is ordered until you accept.
- Fit, test and hand over. On the agreed dates the engineer installs the equipment, commissions the operator and tests each safety function. You get a demonstration, the test record and any conformity paperwork that applies to the work.
Send us the room type, opening size and any specification you have, and we will arrange a free survey in Derry/Londonderry for a hermetic sliding door.
Hermetic sliding doors in Derry/Londonderry: questions
Can our existing theatre door in Derry/Londonderry be upgraded rather than replaced?
Sometimes. Where the leaf and frame are sound, new seals, an adjusted or replaced operator and new touch-free switches can restore performance. Where the frame is damaged or the door is no longer supported, replacement is usually better. The survey looks at both and explains the difference.
How are prices worked out for hermetic sliding doors in Derry/Londonderry?
Our guide starts from £8,995 excluding VAT (per door), the same guide price we use across the UK. The free site survey in Derry/Londonderry confirms the price as a fixed, itemised written quote, and the guide price tool gives you a range before anyone visits.
Do you install hermetic sliding doors in Derry/Londonderry?
Yes. We arrange hermetic doors for hospitals, clinics, laboratories, pharmacies and production sites in Derry/Londonderry and across County Londonderry. Specialist automatic door engineers working under our management survey, install and commission the doors, and we remain the contracting party responsible for the work and the paperwork.
Can you work within our infection control procedures in Derry/Londonderry?
Yes. Work in clinical and cleanroom areas is planned around your permits, screening and dust control requirements, and around room shutdowns. Share your procedures at the survey and we will build them into the method statement and the programme for the installation.
Will the building stay secure while the entrance is being changed?
We plan to keep the entrance usable or secure throughout. Where a door has to come out, the work is sequenced so the opening is closed up before the engineer leaves, or a temporary door or hoarding is arranged when a longer gap cannot be avoided. How this is handled for your site in Derry/Londonderry is agreed before work starts.
What happens to the old door when a new one is fitted in Derry/Londonderry?
If the work replaces an existing door, frame or operator, removal and disposal are listed in the quote. The old door comes out only when the new one is ready to go in, so the opening is not left empty for longer than necessary. Making good to the surrounding wall, floor or ceiling is included where the quote says so.
What do the building regulations in Northern Ireland say about powered doors?
The Building Regulations (Northern Ireland) 2012 require a powered door to have a means to prevent it trapping anyone and a means to open it if the power fails. Guidance on access is in Technical Booklet R, and new entrances need building control approval.
