Overhead Door Company of Berwick provides superimposed service doors to maintain a comfortable working environment without compromising essential protections.
This challenge became especially apparent in the boiler room area. Although the facility was required to keep all openings protected against rodents, the boiler room doors were frequently left open to help reduce heat buildup—creating a conflict between regulatory compliance and day-to-day operational comfort.
Boiler rooms naturally generate high levels of heat, and the staff often relied on fully open doorways to maintain better airflow. However, open doors quickly became a vulnerability point. Without proper barriers, rodents could easily enter the space—posing health, safety, and maintenance concerns.
The building owner needed a solution that allowed ventilation without sacrificing protection. By installing McKEON® Super Imposed Model PF3000-M-G Perforated Service Doors, the building owner gained full control of the opening while maintaining a safe, compliant environment. This system features both a perforated door for airflow and ventilation and a solid slat service door for security, temperature control, and flexibility. Together, these service doors work in tandem to offer a customizable, layered solution.
The perforated door allows airflow while keeping rodents and debris out—a critical upgrade for the boiler room environment. Meanwhile, the solid slat service door can be positioned at varying heights depending on outdoor temperatures and ventilation needs. This gives facility staff the ability to maintain cooler working conditions, protect all required openings against rodents, adjust temperature and airflow throughout the day and improve overall safety and compliance.
With the installation of super imposed doors, the building owner no longer must choose between comfort and compliance. The system provides the flexibility to maintain ideal working temperatures while ensuring the boiler room remains protected, supporting both safety standards and operational efficiency.
