SECTIONAL DOOR SYSTEMS
The Thermospan 200-20 outperforms other
conventional insulated steel doors in the
area of energy efficiency.The Thermospan 200-20
offers a U-Value of .057 (R-value of 17.5) – a
dramatic improvement over most conventional
insulated steel doors, which typically have U-values
between .33 and .51. At the heart of the
Thermospan 200-20’s excellent insulation qualities
is a patented manufacturing process during which
the polyurethane core is continuously foamed-in-
place between the outer and inner skins,forming a
homogenous sandwich of steel/polyurethane/steel.
This process creates outstanding thermal,strength,
and bonding characteristics which combine to
make the Thermospan 200-20 an ideal choice for
commercial and industrial applications. Additionally,
a non-conductive thermal break virtually stops
hot or cold outside temperatures from being
transmitted to the inside.
Materials & Construction
TheThermospan 200-20 also features two patented

" integral roll-formed struts per section
providing the highest strength-to-weight ratio.
Part of what makes the Thermospan 200-20
virtually maintenance free is the pre-painted flush
exterior surface. This outer skin of hot-dipped
galvanized,structural quality steel is factory finished
with baked-on corrosion-resistant primer and a
white polyester finish coat.The inner skin is also
hot-dipped galvanized steel factory finished with
the same corrosion-resistant primer and polyester
finish coat.
The Thermospan 200-20 features an
innovative thermal break that keeps the
interior skin at room temperature, preventing
condensation and frost and thereby resisting
corrosion. A flexible vinyl bulb seal and
non-corrosive polymer retainer prevent water and
air filtration at the bottom of the door.
Reinforcement plates are located at all hardware
attachment locations, and industry standard
commercial-grade, heavy-duty, hot-dipped
galvanized hardware also contribute to the
Thermospan 200-20’s long service life.

Joint seal prevents air infiltration
and saves energy.
Thermal break separates inner and outer
skins so virtually no heat or cold is conducted
through section.
Prepainted inner and outer skins for added
corrosion-resistance.
NOTE: Both skins are also hot-dipped galvanized
steel for further protection against corrosion.
Solid polyurethane core provides
maximum thermal efficiency and adds to quiet
operation and strength.
Two-inch nominal thickness.
Integral struts
Two 1 3/4" roll-formed struts per section
increases rigidity and strength.
Rugged 20-gauge smooth, flush
exterior skin gives theThermospan
200-20 excellent strength qualities, ideal
for large openings.
Vision Lites allow for visibility while
maintaining security
