Hospital Curtain Wall & Facade Solutions
Specialized envelope systems for hospitals, clinics, and medical complexes — engineered for infection control, patient comfort, and regulatory compliance.
What Makes Healthcare Facades Different
Hospital and medical facility envelopes face unique demands that standard commercial curtain wall systems cannot address without careful engineering and material selection.
Infection Control
Smooth, non-porous surfaces that resist bacterial colonization. Sealed joints and flush detailing eliminate dust traps where pathogens accumulate. Anti-microbial coatings on aluminum components reduce surface bioburden in patient-facing areas.
Patient Recovery & Daylight
Research links natural light exposure to faster recovery times and reduced medication use. Healthcare facades must maximize daylight penetration while controlling glare and UV — requiring advanced glazing selection and shading strategies.
Emergency Egress & Safety
Patient mobility limitations demand fail-safe emergency egress pathways. Operable windows must balance fresh air access with fall protection. Fire-rated assemblies and smoke control integration are mandatory for patient safety zones.
Thermal Comfort for Equipment
Diagnostic imaging rooms, operating theaters, and pharmaceutical storage require tight temperature and humidity control. Facade thermal performance directly impacts HVAC load and equipment reliability — demanding U-values below 1.2 W/m²K.
Acoustic Privacy
Patient confidentiality and recovery rest require exterior noise attenuation of 35-45 dB. ICU and maternity wards need the highest acoustic isolation, achieved through laminated glazing, acoustic breaks, and mass-damping design.
Maintenance Access
24/7 operational continuity means facade maintenance cannot disrupt patient care. Unitized systems with external-only access requirements and modular component replacement minimize downtime and infection risk during repairs.
Healthcare Facade Regulatory Framework
Hospital curtain wall systems must navigate a complex landscape of building codes, healthcare-specific guidelines, and infection control standards.
| Standard / Guideline | Application | Hanart Compliance |
|---|---|---|
| FGI Guidelines (Facilities Guidelines Institute) | Patient room daylight, infection prevention, material specifications | Design review against latest FGI edition for all healthcare projects |
| ASTM E331 (Water Penetration) | Static pressure water testing for curtain wall assemblies | Tested to 720 Pa with zero penetration; reports available |
| ASTM E330 (Structural Load) | Wind load structural performance testing | Tested to design wind load × 1.5 safety factor |
| NFPA 285 (Fire Propagation) | Combustible components in exterior wall assemblies | Non-combustible mineral wool insulation; fire-stopped perimeters |
| IBC Chapter 12 (Interior Environment) | Natural ventilation, light, and space requirements | Operable window integration with insect screening and limit stays |
| ASHRAE 170 (Ventilation of Healthcare Facilities) | Pressure relationships, air changes, filtration | Facade air tightness supports pressure differential maintenance |

What Healthcare Clients Say
"Hanart understood the unique demands of hospital construction from day one. Their unitized panels with pre-applied antimicrobial coating eliminated our infection control committee's concerns about facade surfaces. The phased installation allowed us to keep existing wards operational — a critical requirement we hadn't found with other suppliers."
Healthcare Facade FAQ
How do you ensure infection control in curtain wall systems?
We use smooth, non-porous aluminum surfaces with anti-microbial powder coating (tested to ISO 22196 for bacterial reduction). Silicone jointing is flush without exposed cavities. All patient-facing surfaces are designed for wipe-down compatibility with standard hospital disinfectants including quaternary ammonium and bleach solutions.
What glazing options do you recommend for patient rooms?
For patient rooms, we recommend triple-glazed units with U-value ≤ 1.1 W/m²K, VLT 60-70% for daylight without glare, and integrated UV blocking (UV transmittance < 1%) to protect medications and equipment. Solar heat gain coefficient (SHGC) should be 0.25-0.35 depending on climate zone. Laminated inner pane provides safety and acoustic benefits.
Can your systems accommodate emergency egress requirements?
Yes — our HC-Unitized system integrates coded emergency release hardware on operable vents, with fall protection compliant to IBC 1015.2. For behavioral health units, we offer anti-ligature hardware with restricted opening widths. Fire-rated egress assemblies available up to 120 minutes rating with clear visibility for egress path monitoring.
How do you handle construction phasing around occupied hospitals?
Unitized panels are factory-finished and pre-tested, minimizing on-site work duration. We coordinate installation through temporary weatherproofing systems that maintain building envelope integrity between phases. Dust containment protocols and after-hours installation options are standard for healthcare projects.
What warranties do you provide for healthcare facades?
Standard 10-year warranty on glazing seal integrity and aluminum finish durability. Extended 15-year warranty available with annual inspection protocol. Anti-microbial coating performance guaranteed for 10 years under normal cleaning protocols. Thermal performance warranty based on project-specific U-value testing.
