Weather Seal Brush

Precision Brush weather seals provide a quick return on investment in energy savings. They can be found everywhere from residential garage doors to large commercial overhead doors and even aircraft hanger doors. Precision Brush door seals are more effective than rubber or vinyl seals, as the independent filaments of the brush properly conform to irregular surfaces for a more complete seal.

Weather Seals keep rain, wind, dust, sand, sleet, snow and debris out of your building. However, they are most commonly used to minimize drafts. Air infiltration and leakage is a problem in most buildings, especially around overhead doors and loading docks. Pedestrian doors and conveyors can also be problem points that can require Precision Brush weather seals. Not only can cooled or heated air escape, leading to unnecessary utility bills, but drafts can also cause uncomfortable working conditions.

Air leakage problems are also compounded by what is commonly known as the “chimney” or “stack “effect. Hot air rises and escapes through openings near the top of the building while cold air is drawn in through door gaps and openings near the bottom of the building. Depending on temperatures, air movement caused by the chimney effect can move up to 10 mph.

Precision Brush's strip brushes designed as weather seals can stop up to 99% of air infiltration and can be up to 3 times as effective as vinyl seals, as illustrated in this chart:

Wind Speed No Weather Seal Vinyl Seal (Top & Sides) Brush Seals (Top & Sides)
15 mph 6.24 cfm/ft2 0.30 cfm/ft2 0.10 cfm/ft2
25 mph 13.10 cfm/ft2 0.64 cfm/ft2 0.21cfm/ft2

All doors require a clearance gap in order to work properly. Unfortunately, this clearance gap also allows for air leakage and infiltration. Our strip brushes pay for themselves quickly by saving money on utility bills and also reduce environmental impact by requiring less energy to be produced.

Chart: Pedestrian door 3’ x 7’ with a 1/8” gap is equivalent to hole measuring 25.5” square inches. Overhead door 10’ x 10’ with a ¼” gap is equivalent to a hole measuring 90 square inches.
