Hospitals, medical centres, specialist clinics and aged care facilities must balance clinical function, fire egress, acoustic privacy, and accessibility, all within a tightly regulated framework. This article steps through the key considerations relevant to Australian healthcare projects, with a focus on interior building systems, doors, partitions, and glazing.

The Regulatory Framework

Healthcare design in Australia is governed by a layered hierarchy of documents. At the top sits the National Construction Code (NCC), which classifies hospitals and private health facilities as Class 9a buildings. Below that, the Australasian Health Facility Guidelines (AusHFG) — developed by the Australasian Health Infrastructure Alliance (AHIA) — provide detailed design guidance across planning, environmental design, and specific room and space requirements. State-level guidance, such as the Western Australia Health Facility Guidelines for Engineering Services (WAHFG ES), adds jurisdictional specificity.

For doors and glazing, the primary referenced Australian Standards include:

• AS 1288 — Glass in Buildings: Selection and Installation
• AS 1905.1 — Components for the Protection of Openings in Fire-Resistant Walls (fire door sets)
• AS 1428.1 — Design for Access and Mobility (accessible doorways)

Acoustic Performance: A Clinical Necessity, Not a Comfort Feature

In residential or commercial fitouts, acoustic privacy is desirable. In healthcare, it's a clinical imperative.

The guidelines call for adequate acoustic treatment in consulting rooms, inpatient bedrooms, mental health units, and any space where patient confidentiality and clinical privacy intersect.

As a general guide, door and partition systems in sensitive clinical zones, consulting rooms, inpatient bedrooms, operating theatres, are often specified in the Rw 40 or above range, with lower-sensitivity separations typically falling in the Rw 25–35 range. Specific performance requirements will vary by jurisdiction and project, and should be confirmed against the applicable guidelines and acoustic consultant advice. 

For doors, the acoustic chain is only as strong as its weakest element. A high-performing partition paired with an inadequately sealed or underspecified door creates a flanking path that undermines the entire system. 

Interior Glazing: Visibility, Privacy, and Compliance

The AusHFG takes a nuanced position on interior glazing. Vision panels in doors are frequently required for the safe and efficient operation of clinical spaces enabling staff to monitor patient areas, reduce door-related collision risks in high-traffic corridors, and maintain sightlines in procedure and consultation settings. At the same time, the guidelines are clear that glazing in areas requiring acoustic isolation must be specifically designed to achieve the required acoustic rating, and that rooms requiring radiation shielding (operating theatres, radiology suites) or electromagnetic shielding require special treatment.

There are specific healthcare contexts where glazing must incorporate obscuring mechanisms — consulting rooms, change areas, patient bedrooms, and areas where privacy is a clinical requirement. The AusHFG recommends integral venetian blinds between glass panes for these applications, offering protection against damage and reducing dust accumulation risks.

Key specification watchpoints

• Vision panels must be sized and positioned for use by the majority of occupants — the AusHFG references an eye height of 685–845mm for seated users, relevant to patient and wheelchair-accessible design.
  
• Glazing in areas requiring acoustic isolation must be co-specified with the acoustic performance of the whole assembly
• Radiation shielding requirements in imaging departments and procedure rooms add a further layer beyond standard AS 1288 obligations

Criterion's Definium 90 is a glazed partition system well suited to clinical environments, available in DGU configuration, which also accommodates integrated venetian blinds where privacy screening is required. For higher-demand applications such as main hospital corridors or clinical suites where durability is a primary consideration, the Definium 145 offers a heavy-duty glazed partition solution within the same product family.

Fire Compliance and Compartmentation

Fire compliance adds another layer to the door specification process in healthcare. Doors forming part of a fire or smoke compartment carry obligations around performance, hardware, and glazing that need to be considered alongside acoustic and accessibility requirements and these can sometimes pull in different directions.

Having acoustic and fire-rated door solutions available within the same supplier's range simplifies this process, reducing the need to cross-reference compliance obligations across multiple product warranties and suppliers.

Key Takeaways for Architects

Healthcare fitouts leave little room for specification gaps. Before locking in your door and partition schedule, it's worth running through these fundamentals:

• 01 Specify acoustic systems, not individual products. Partition, door leaf, and seals all contribute to the final Rw outcome.
• 02 Glazing in acoustic zones requires its own acoustic rating. Vision panels and sidelights must be co-specified with the assembly, not added independently after the wall system is resolved.
• 03 Door swing, closer selection, and hardware all have compliance implications — from fire egress direction requirements to DDA lever handle obligations and the AusHFG's cautions on closers in patient movement areas.
  
• 04 Test data matters. Specifying products with independent CSIRO or NATA-accredited acoustic reports makes compliance documentation straightforward.

Criterion Industries' Silencio range — tested at CSIRO's acoustic laboratory  provides documented Rw performance data for all products, with specification sheets, and acoustic reports available for download. Our specification support team is available to assist with product selection and system integration guidance for your healthcare project.
