Hollow metal door weatherstripping is specifically designed for use with hollow metal doors, which are commonly found in commercial and industrial buildings. These doors consist of a hollow metal frame filled with insulation material and covered with metal sheets on both sides. Weatherstripping is essential for these doors to maintain a proper seal and prevent air, water, and dust infiltration.

Here are some common types of weatherstripping used for hollow metal doors:

1. Door Sweeps: These are attached to the bottom of the door and help seal the gap between the door and the threshold. Door sweeps for hollow metal doors often feature brushes or rubber seals to provide a tight seal.

2. Door Jamb Weatherstripping: Installed along the sides and top of the door frame, door jamb weatherstripping creates a seal between the door and the frame when the door is closed. This helps prevent drafts and ensures energy efficiency.

3. Gasketing: Gasketing is a type of weatherstripping that consists of a compressible material, such as neoprene or silicone, attached to the door frame. When the door is closed, the gasket compresses to form a tight seal between the door and the frame.

4. Interlocking Weatherstripping: This type of weatherstripping features metal strips that interlock when the door is closed, providing a secure seal along the door edges. Interlocking weatherstripping is often used in conjunction with door sweeps and gasketing for comprehensive weatherproofing.

Hollow metal door weatherstripping is typically durable and resistant to wear and tear, making it suitable for high-traffic areas and harsh environmental conditions. Proper installation and maintenance are crucial to ensure the effectiveness of the weatherstripping over time.
