Lynden Door VA8 VanAir Ventilated Door (1-3/8″)

The VA8 VanAir delivers up to 355 CFM of airflow at 50 Pa while maintaining 25 STC sound privacy — solving the traditional trade-off between ventilation and acoustic control. This 1-3/8 inch door integrates vertical ventilation channels with acoustical baffles and Helmholtz resonator construction, providing passive airflow without sacrificing privacy or requiring visible grilles.

For commercial contractors working on multi-family housing, hotels, and healthcare facilities, the VA8 addresses a persistent challenge: rooms need fresh air circulation to control humidity and CO2, but standard solutions compromise either sound privacy or aesthetics. This door eliminates the need for undercutting while improving indoor air quality through passive ventilation.

Airflow Performance That Matters

The numbers tell the real story. Testing shows two distinct performance configurations:

Configuration	5 Pa	10 Pa	12 Pa	20 Pa	35 Pa	50 Pa	Source
Sound-Privacy Version	100 CFM	156 CFM	170 CFM	219 CFM	297 CFM	355 CFM	(manufacturer)
Max-Airflow Version	199 CFM	312 CFM	340 CFM	436 CFM	581 CFM	696 CFM	(manufacturer)

At 170 CFM at 5Pa, the sound-privacy version delivers airflow comparable to a 12”x12” louver — but without the visual disruption or sound leakage. The door achieves this through up to 140 square inches of vent area with approximately 50% free open area.

These aren’t theoretical numbers. Bathroom exhaust fans typically require 50 CFM continuous or 100 CFM intermittent. The VA8 exceeds both targets through passive pressure differentials alone, reducing mechanical ventilation demands.

Sound Privacy Engineering

The acoustic performance comes from Helmholtz resonator construction integrated directly into the core, with acoustic baffles attenuating both high- and low-frequency sound. The result: up to 25 STC when configured with perimeter seals and acoustic foam.

That 25 STC rating matters. Standard hollow-core doors achieve only 22 STC, while solid-core doors reach 28 STC but provide zero airflow. The VA8 splits the difference — delivering meaningful sound privacy while actually moving air.

The ventilation slots stagger on opposing faces for a discreet appearance. No visible grilles. No obvious louvers. Just what looks like a standard door that happens to breathe.

Installation Without Complications

The VA8 works with standard door hardware — hinged, pocket, double-door, and sliding configurations all compatible. It fits standard door frames without proprietary mounting systems or special rough openings.

Factory machining follows supplied hardware templates, eliminating field modifications. Architects get fully parametric Revit models with airflow calculation properties built in — useful for LEED documentation and mechanical engineering coordination.

Key specifications:

• Maximum dimensions: 4’0” x 10’0” (custom sizes available on factory request)
• Face options: Wood veneer (prefinished smooth or embossed), paint-grade hardboard, HPDL, FineLine, Elemental™. Stiles and rails: Mill-option clear or finger-jointed softwood or composite material
• Warranty: 1 Year Limited on manufacturing defects, interior use only

The Bottom Line

The VA8 earns its premium positioning through genuine performance advantages. Reducing humidity and CO2 more effectively than undercut doors while preventing sound leakage justifies the investment in bathrooms, laundry rooms, and equipment spaces where moisture control prevents long-term damage.

With Type 2 adhesives and No Added Urea-Formaldehyde (NAUF) components plus No-VOC factory finishes, the door meets current green building standards. WDMA IS-1A Extra Heavy Duty rating (when specified with appropriate blocking) ensures commercial-grade durability for Montana’s building codes.

This isn’t a door for every opening. But where passive ventilation, sound privacy, and clean aesthetics converge — multi-family corridors, hotel bathrooms, healthcare patient rooms — the VA8 delivers measurable benefits over traditional solutions.

Frequently Asked Questions

How does the VA8 compare to standard door undercuts for ventilation?

The VA8 eliminates the need for undercutting doors while reducing humidity and CO2 more effectively than large undercuts. Standard 1-inch undercuts compromise sound privacy significantly. The VA8 maintains 25 STC acoustic performance while moving more air than typical undercut solutions.

What face materials work with the ventilation system?

Available faces include wood veneer (prefinished smooth or embossed), paint-grade hardboard, HPDL (high-pressure decorative laminates), FineLine, and Elemental™. The standard 7/8 inch vent slot width is customizable to work with different face materials and aesthetic requirements.

Can the VA8 meet fire-rating requirements?

No. The door carries a non-fire-rated designation. For fire-rated openings, specify conventional solid-core fire doors and address ventilation through mechanical systems or transfer ducts with appropriate fire dampers.
