Ideal for applications where energy efficiency
is important, and competitive cost is essential,
Wayne-Dalton’s Thermospan 125 sectional door
features a foamed-in-place polyurethane core
firmly bonded to hot-dipped galvanized inner and
outer skins. Integral roll-formed struts per section
add rigidity and strength, making the Thermospan
125 suitable for commercial and industrial
applications. The patented Thermospan design
demonstrates that overhead doors need not be
the weak link in an energy-efficient building.
Materials & Construction
Thermospan 125 doors feature pre-painted inner
and outer skins made from hot-dipped galvanized
steel for added corrosion protection.The exterior
suface is pebbled and grooved, enhancing the
appearance while providing improved strength, and
each section is reinforced with two 1
roll-formed struts for even greater rigidity.
Hot-dipped 18-gauge galvanized end caps offer a
superior surface for hinge attachment. Our
standard joint seal prevents air infiltration and, in
conjunction with the solid polyurethane core,
offers enhanced energy efficiency.
Factory-installed vision lites (24" x 6") are
available, as are automatic door openers.
3
/4" integral
Pre-painted (white polyester finish)
inner and outer skins provide corrosion
resistance. Both skins are hot-dipped galvanized
steel for further protection against corrosion.
Pin stripes (grooves) and pebble finish on outer
skin add strength and enhance appearance.
Two patented, integral 1 3/4" roll-formed struts
per section add rigidity and strength.
(* industry exclusive)
18-gauge hot-dipped galvanized
steel “wrap-around” end caps
offer interior hinge attachment surface
and exterior leg for proper seal against
jamb.
Solid polyurethane
core adds to insulating
efficiency.
Standard joint seal prevents
air infiltration and saves energy.
