Light Control
Weather & Brush Seals for Light Elimination
Unwanted light leakage through door gaps and openings is often an indicator of poor sealing—and a pathway for pests, air loss, and contamination. Memtech brush seals provide an effective solution for light control by sealing gaps completely while conforming to uneven surfaces.
Light Elimination with Brush Seals
Memtech nylon brush seal assemblies are manufactured with dense filament patterns that block light transmission when installed along doors and frames. Because the bristles conform to variations in gap size, brush seals maintain continuous contact along the full length of the opening.
In food processing and regulated environments, visible light around a door often indicates gaps large enough for insects, rodents, and contaminants to enter. Eliminating light leakage helps support sanitation inspections and overall facility compliance.
Light Control for Sensitive Environments
Brush seals are widely used in environments where light intrusion cannot be tolerated, including photographic darkrooms, theaters, simulation rooms, and controlled testing areas. Unlike rigid sealing materials, brush seals maintain performance even when doors cycle frequently or surfaces are uneven.
Memtech offers stock nylon brush trims ranging from approximately 0.4″ up to 17″+, allowing precise selection based on gap size and application requirements.
Benefits of Brush Seals for Light Control
- Eliminate visible light leakage around doors and openings
- Seal uneven surfaces and variable gap sizes
- Support sanitation and inspection compliance
- Prevent pest entry through light-visible gaps
- Maintain performance in high-cycle door applications
- Durable nylon bristles with long-term memory
If light leakage is present around your doors or controlled environments, Memtech Brush can help identify the right sealing solution.
