SEALEZE® provides a broad range of products specifically designed to improve the thermal efficiency of buildings, reduce pest problems, and improve personnel comfort and safety.

Brush Weatherseals
SEALEZE® brush weatherseals close gaps around all types of doors, ranging from home entrance doors to large industrial overhead doors, barn doors and aircraft hangar doors. SEALEZE® brush weatherseal conforms to irregular surfaces to provide the most effective seal possible. More effective than vinyl or rubber seals, SEALEZE® brush consists of thousands of filaments that form a solid wall that closes gaps with a complete weather-tight seal without impairing door movement.

We make our weatherseal brush products from the finest nylon and polypropylene filament materials and our holders are made from sturdy extruded aluminum in a variety of finishes.
