Our Brush Door Seals
have been designed and tested for:
-
Hot weather applications –
keeping the cool air in
-
Cold weather applications – keeping the cold
weather out
-
Only a Memtech brush
seal
can seal so completely along uneven surfaces
as the individual bristle nest together along the surface.
-
The use of strip nylon
brushes for door seals, weatherstripping and weather seals has been
proven as superior door seal barriers
-
A Memtech nylon brush seal
or weather seal for doors far outperforms vinyl or rubber strips as
a door seal
The nylon bristles on our weather seals and door
seals conform to irregularities, and a wide variety of bristle lengths,
thicknesses and mounting extrusions allow for any door sealing
application.
A Brush Seal is the only
fully flexible air-tight door seal available for doors and dock
levelers. The technology of brush also serves industry as a deflector on
drilling or surfacing machines, a parts & product guide and a sound or
temperature blocker.
The brush – normally a
nylon formulation – is looped around a central wire, crimped into a
steel channel and trimmed to size (about 1200 filaments per inch). This
assembly is normally slid into an aluminum extrusion designed to fit a
particular door or use. The brush can be cut as short as ¼ “ or as long
as 24’ and the extruded holder can be
nearly any angle to suit the task at hand.
The extrusions holding the
brush are made in several sizes to fit different jobs. These begin with
A
and go through J.
An “A35MIL07- 63”
as an example, is a small strip used on pedestrian doors. The first
letter is the size (A)
then the angle the brush is set (35
degrees),
MIL
means it’s plain aluminum
or mill finish (others could be CLA
for anodized or BRA
– brown finish). The 07
is the length used for
pricing (7 ft) and the final number is the length of brush
(.063” inch).
An F40MIL12 – 03.0
describes a larger extrusion (F)
mil finish, 12
ft long (for pricing and usually cut 6’ & 6’ or 8’ & 4’ for shipping),
with a 3
inch brush.
Additionally, we have an extensive custom design department in which we
develop special brushes for nearly any application a client might
present.
Brush seals for:
Non-chemical Pest Control
Use Memtech nylon brush weatherseals and
nylon brush door seals as non-chemical pest control to keep flying and
crawling insects and small animals outside of your facility.
Air Flow Control
Memtech Brush door seals and weatherseals
are highly effective physical barriers to control air flow for both
heating and cooling on all types of gaps in windows and doors.
Dust Control
Seal buildings, clean rooms, computer
rooms, machinery, and filtration systems from the ravages of dirt and
dust particles with brush door seals and weather seals.
Light Control
Effectively reduce or eliminate light
transfer in sensitive areas such as darkrooms with a Memtech weather
seals and brush door seals.
Sound Control
Brush seals and weather seals create
barriers to control infiltration from fan rooms, test cells and
machinery when the individual brush bristles as door seals follow contours to seal the
gaps.
Nylon Brush
Seals
Our type 6 nylon weather seals and brush
seals are UL. Rated as "Gasketing Material for Fire Doors" (viable from
-100ºF to -200ºF).
