Acoustical Doors
Our acoustical doors provide exceptional sound control with STC ratings up to 51. These specialized doors use advanced core materials and sealing systems to prevent sound transmission in recording studios, hospitals, and government facilities. Custom-engineered solutions ensure compliance with strict acoustic performance standards while maintaining aesthetic flexibility through multiple finish options.
Bullet-Resistant Doors
Engineered to meet SD-STD-01.01 forced entry resistance standards, our bullet-resistant doors withstand multiple rounds from high-powered rifles. The multi-layered construction combines steel frames, reinforced cores, and ballistic-rated materials to protect personnel in high-risk environments while maintaining ADA compliance and operational functionality.
Radio Frequency Doors
Our radio frequency-shielded doors provide 40 dB+ protection for secure communication facilities. The hybrid design integrates conductive gaskets and specialized materials to block electromagnetic interference while maintaining acoustic performance. These doors enable secure access to Faraday enclosures and SCIF-compliant spaces without compromising structural integrity.
Blast-Resistant Doors
Designed to withstand extreme pressure events, our blast-resistant doors protect critical infrastructure including nuclear facilities and industrial plants. The reinforced steel construction with 5 PSI pressure resistance rating ensures personnel safety while maintaining operational functionality through tested hinge and locking systems that remain functional after pressure events.
Tornado Doors
Engineered to meet FEMA 361 storm shelter requirements, our tornado-rated doors provide critical protection in hurricane-prone regions. The reinforced frame system and impact-resistant glazing withstand extreme wind loads and flying debris while maintaining accessibility and code compliance for emergency egress pathways in commercial and public buildings.
