Key Product Features:

  • Polyurethane insulation, R-Value=17.5
  • Max Width 40’2”
  • 2” Section Thickness
  • Patented, roll-formed integral struts for rigidity
  • Embossed stucco with pinstripes available in white, brown, and tan

Wayne Dalton Thermospan® 200 provides premium thermal efficiency and low maintenance costs, resulting in a door that costs less to own. Continuous foamed-in-place polyurethane insulation and a non-conductive thermal break between the inner and outer skins combine to provide a U-value of .057 and an R-value of 17.50. The Wayne Dalton Thermospan® Series doors are the only sectional doors in the industry with patented, roll-formed integral struts on each section, making them the most rigid doors available.

Materials & Construction

door construction of insulated sectional steel door model 200

The secret behind the exceptional thermal efficiency is Wayne Dalton’s patented manufacturing process, during which the polyurethane core is continuously foamed-in-place between the outer and inner steel skins to form a homogenous sandwich of steel/polyurethane/steel. The technique produces outstanding thermal, strength and bonding characteristics.

Additionally, a non-conductive thermal break virtually stops hot or cold outside temperatures from being transmitted to the inside. This innovative thermal break 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.

The Thermospan® 200 also features two patented 1 3/4" integral roll-formed struts per section providing the highest strength-to-weight ratio. The embossed stucco outer skin adds additional strength and enhances its appearance. 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’s long service life.
