Structural System
Strut Design	Patented roll-formed integral struts on each section — same construction as Model 200
Manufacturing Process	Patented continuously foamed-in-place polyurethane core
Hardware	Commercial-grade galvanized hardware throughout
Finish	Baked-on polyester finish — virtually maintenance-free
Steel	Hot-dipped galvanized steel
Thermal Performance
Insulation	CFC- and HCFC-free foamed-in-place polyurethane core
Thermal Break	Separates inner and outer skins at top and bottom — prevents heat/cold conduction through section
Condensation Prevention	Thermal break keeps interior skin at room temperature — prevents condensation and frost
Air Infiltration	Standard joint seal plus CFC-free core aids in preventing air infiltration
Bottom Seal	Flexible vinyl bulb seal with non-corrosive polymer retainer
Wind Load
Wind Load Options	FBC and TDI approved wind load reinforcement available
Warranty
Coverage	10-Year Limited Warranty against cracking, splitting, rust deterioration and delamination (Model 150)

Wayne Dalton uses a calculated door section R-value and U-value for insulated doors. FBC and TDI approved wind load reinforcement available for hurricane-prone areas.

The Thermospan® 150 brings the same patented integral strut and foamed-in-place polyurethane construction as the heavier Model 200 to a medium-duty configuration — the right choice where standard insulated sectional doors are insufficient but the full heavy-duty Model 200 exceeds application requirements.

Same patented Thermospan® integral roll-formed strut system as Model 200 — the most rigid insulated sectional door in its class, with struts built directly into each section during manufacturing

Patented continuously foamed-in-place polyurethane core bonds to both steel skins, eliminating insulation voids and gaps that reduce real-world thermal performance

Thermal break separating inner and outer skins at top and bottom of each section prevents heat and cold conduction through the section profile — keeps interior skin at room temperature year-round

Prevents condensation and frost on the interior skin — important in Oklahoma City's seasonal climate for both operational comfort and long-term corrosion prevention

Commercial-grade galvanized hardware throughout provides long service life in demanding commercial environments

Hot-dipped galvanized steel construction for deep corrosion protection in agricultural, maintenance, and chemical-exposure environments

10-year limited warranty against cracking, splitting, rust deterioration, and delamination

The Thermospan® 150 is suited for medium-to-heavy duty commercial and industrial applications where standard insulated sectional doors are insufficient. Contact DOORTEC to confirm the right Thermospan® model for your specific facility and duty cycle.

Thermospan® 150 in Oklahoma City

The Wayne Dalton Thermospan® 150 brings the same patented integral strut and foamed-in-place polyurethane construction as the Model 200 to a medium-duty commercial configuration — the right choice for Oklahoma City commercial buildings, equipment storage facilities, and maintenance structures where a standard insulated sectional door provides insufficient structural rigidity or thermal performance. DOORTEC installs the Thermospan® 150 throughout Oklahoma City, Edmond, Norman, Moore, Yukon, Midwest City, Guthrie, El Reno, and the OKC metro.

For OKC facility managers comparing the Model 150 and 200, both share the same patented construction, thermal break, and 10-year warranty — the 200 is rated for heavier duty applications. DOORTEC's commercial team will assess your specific facility and recommend the right model. Call (405) 720-7107 for a free site assessment.
