New Design Stc Over 45dB Soundproof Metal Doors Hotel/Recording Studio Acoustic Door

UL (Underwriters Laboratories) Listed fire rated steel doors are doors that have been tested and certified by UL to meet specific standards for fire resistance and safety. These doors are designed to prevent the spread of fire and smoke for a specified amount of time, usually ranging from 20 minutes to 3 hours.

• Steel construction: Durable and fire-resistant material providing protection against heat.
• Fire-resistant core: Materials such as gypsum or mineral wool reduce heat transfer.
• Intumescent seals: Expand when exposed to heat to form a smoke barrier.
• Self-closing mechanism: Automatically closes when sensing heat or smoke.
