Therma Tech II ranks second in our Therma Tech range of insulated steel doors with elevated steel panels with an insulation value of 10.4. It has a multi-layer construction, flexible joint sealing, and natural thermal break.
Therma Tech II is built using the time-tested Northwest Door sandwich construction. This construction method has proven itself to be superior over the past twenty years on hundreds of thousands of Northwest doors in homes across Canada.
Four wood grain textured panel designs are available: Modern Flush, Traditional Panel or Short Raised Panel, Ranch Panel or Long Raised Panel, and Carriage Panel.
The doors are hot-dip galvanized, primed, and then pre-painted in one of four standard colors: Bright White, Almond, Sandstone, and Brown.
Torsion hardware in 15 or 20-in. radius; rail mounted on a 2-in. bracket. Silent, long-lasting nylon casters, non-corrosive door hardware and graduated hinges are standard. U-shaped galvanized posts are supplied with each double car door to keep the door rigid.
The doors are made of 25-gauge steel and have tongue and groove connections between sections. They are available with all window and panel designs except the modern concealed design. Supplemental vinyl-lined foam is an affordable option for acoustical and moderate thermal protection.
Garage door openers are the recommended option for these doors. They are convenient and will extend the life of your garage door.
