A distributor in the Gulf region once ordered forty "hospital doors, stainless steel, fire rated" for a new clinic — only to find on site that the operating theatres needed hermetically sealed sliding doors, the X-ray rooms needed lead lining, and the ward doors needed neither of those but did need impact protection. The specification failure was not about quality; it was about skipping a selection framework. Medical doors are bought against the wrong criteria more often than almost any other building product, because "hospital door" covers at least six functionally different products.

Step 1 — Define the application, not the door

Start with the room, not the product catalogue. The main application classes:

Application Dominant requirements
Operating theatre / sterile core Hermetic or near-hermetic seal, pressure retention, cleanable flush surfaces, hands-free operation
ICU / isolation room Airtightness for pressure cascade, vision panel, touchless access
Ward / patient room Impact resistance, quiet operation, accessibility, wide clear opening for beds
X-ray / radiology Radiation shielding (lead equivalence matched to room calculation)
Laboratory / cleanroom Particle-compatible surfaces, air leakage class, interlocking with adjacent doors
Corridors and exits Fire resistance and smoke control, escape hardware, durability

A single doorset rarely optimises more than two of these. Trying to buy one door that does everything produces expensive compromises.

Step 2 — Material and construction

Material follows from hygiene and durability loads, covered in detail in Chapters 7–10. Short version:

  • Stainless steel (304/316L) — best chemical and disinfectant resistance; 316L where chlorine-based agents are aggressive; higher cost, shows fingerprints unless finished properly.
  • Galvanised/powder-coated steel — good value for wards and corridors; coating integrity is the weak point under trolley impact.
  • HPL-faced doors — warm appearance, good impact resistance, but edges and cut-outs are hygiene risks in wet areas.

Common mistake: specifying stainless everywhere "to be safe". It raises cost 30–60% with no functional gain in a corridor.

Step 3 — Opening method

  • Hinged swing: simplest, most reliable, best sealing per cost, but the swing arc obstructs theatre layouts and cannot be made truly hermetic without compression latches.
  • Sliding (manual or automatic): no swing arc, suits theatres and ICUs; track and drive add maintenance.
  • Hermetic sliding: leaf drops and presses against frame seals at closure — required where pressure differentials must be held.
  • Automatic vs manual: automatic improves infection control (touchless) but brings EN 16005 safety obligations (see Chapter 28) and a maintenance contract for life.

Step 4 — Hygiene and cleanability

Ask for: flush vision panels bonded without exposed frames, no horizontal ledges, sealed core edges, hardware that withstands the site's actual disinfectants. A door that passes every standard but has a dirt-trapping pull handle recess fails its real job.

Step 5 — Sealing and airtightness

Only specify a leakage class if the HVAC design needs it. Quantified airtightness (e.g. tested to EN 1026 / classified per EN 12207, or leakage at 50 Pa stated in m³/h) belongs in the schedule of requirements, not in marketing adjectives like "airtight". See Chapter 29.

Step 6 — Durability and duty class

Match the doorset to traffic. Ward corridor doors see bed impacts daily; check duty/durability declarations (EN 1192 / EN 12400 classify doorset durability and repeated opening cycles) and impact test evidence. Hinges and closers must be rated for the actual leaf weight — a lead-lined or 60-minute fire leaf can exceed 150 kg.

Step 7 — Compliance

Fix the regulatory basket early:

  • Fire/smoke: EN 1634-1 / EN 1634-3 tests, classified per EN 13501-2, CE marking under EN 16034 (Chapter 30).
  • Automatic doors: EN 16005.
  • Non-fire internal doorsets: EN 14351-2.
  • Cleanrooms: ISO 14644-1 class of the room drives leakage and surface requirements.

Evidence documents (test reports, classification reports, DoP) should be requested at tender stage, not at handover.

Step 8 — Budget honestly

Total cost = doorset + frame + hardware + automation + installation + commissioning + maintenance. Automatic hermetic doorsets cost 3–5× a standard hinged doorset and carry annual service costs. Skimping on installation is the classic false economy: a hermetic door mounted in an out-of-square opening will never achieve its tested leakage rate.

Practical checklist

  1. Room function and pressure regime defined?
  2. Material matched to disinfectant regime and impact load?
  3. Opening method suits layout and traffic?
  4. Clear width sufficient for beds/trolleys (Chapter 27)?
  5. Quantified leakage class specified where needed?
  6. Fire/smoke rating matched to compartment drawings?
  7. Duty class and hardware matched to leaf weight?
  8. Test evidence and DoP requested with the quotation?
