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 secret behind this exceptional energy 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. The Thermospan 200 also features two patented 1 3/4″ integral roll-formed struts per section providing the highest strength-to-weight ratio. Part of what makes the Thermospan 200 virtually maintenance free is the pre-painted exterior surface.

Why is it extremely vital to select a steel window that has been tested for air penetration, water penetration and structural integrity?

27. Do steel windows and doors require maintenance? Hot rolled steel windows and doors are made from solid steel sections which are produced from new billet steel into shapes specifically designed for window and door frames and ventilators. Cold rolled steel windows and doors are made from hollow steel sections, which have been mechanically formed from flat coil stock into specially designed profiles. Steel windows and doors are custom manufactured on a project-specific basis and are often chosen for their ability to fill very large openings while maintaining narrow sightlines. Due to the inherent strength of steel, steel windows and doors can be made as large as or larger than any other conventional window and door system available. The inherent strength and durability associated with steel windows and doors results in a product that outperforms any other window material – aluminum, wood fiberglass or vinyl. Hot rolled steel windows are manufactured from 100% recycled steel.

No, with the advances in insulated glass and the ability of steel windows to accept insulated glass, a thermal break is not required. In addition, the end user may control the relative humidity reducing the potential for condensation using existing climate controls. The condensation resistance factor (CRF) of steel windows and doors will vary depending on the size and configuration of the unit, as well as the type of glass. Consult OWM sales staff for specific information. Yes, steel windows and doors are thermally efficient. As an example, the thermal resistance of steel is 5 times greater than that of aluminum. The strength of steel affords narrow sightlines, thus reducing the ratio of glass to framing. The more glass there is in a window or door, the better the U-value. U-values vary depending on the type and thickness of glass used. The U-value for steel windows is calculated for the entire window, including frame material and the glass, and incorporates the style of window, fixed or operable.

The U-value can be either physically tested or simulated with a computer program. The combination of the minimal framing profiles of steel, the low coefficient of heat transfer, and larger glass areas will produce U-values as low as 0.26 for fixed windows, while operable windows can be as low as 0.42. Pre-treatment options include marine galvanization, zinc-enriched primer & E-coat upon request. Finish paints include enamels, polyurethane, & powder coat paints. Consult OWM’s sales staff for more specific information. A paint finish with minimal amount of care can last 10-15 years. Minimal care consists of washing the frames twice a year. (See OWM’s Maintenance Manual)Paint finishes prevent any corrosive interaction between dissimilar metals. Steel windows and doors are typically glazed using glazing tape, glazing wedge, setting blocks, custom pre-fitted glazing beads and a cap bead of sealant on the exterior. Steel windows can accommodate glass thicknesses ranging from 1/8″ to 1-1/2″, including single pane, laminated or leaded glass, and most any of the high performance insulated glass products currently available.

Steel windows are generally provided with continuous snap-in glazing beads which can be easily removed to replace the broken glass and reinstalled with new glazing materials. Due to large custom sizes of steel windows and doors, ease of handling and installation makes field glazing more practical. In the event of a fire, egress windows provide an opening large enough to allow occupants to escape, or to allow a fully-equipped firefighter to enter from the outside. The International Building Codes (IBC) specify the minimum clear opening width for an egress window at 24 in.; the minimum clear opening height is 20 in., and the net clear opening requirement is 5.7 sq. ft. To comply with the Codes, an egress window must be set with a maximum sill height of 44 in.Please contact Optimum for available designs.The windows can easily be limited to the required clear opening restriction, yet can be released for cleaning. Insect or security screens are available. Fire rated windows are used in window openings where it is necessary to restrict the spread of fire within buildings, whether from interior fire or exterior fire.

Steel fire rated windows are available in fixed, casement, projected, vertical sliding, and horizontal sliding configurations. Steel doors are also available for fire rated applications. Fixed, Project-In, Project-Out, Side Hung-Out, Side Hung-In, Vertical Slider, Horizontal Slider, and Pivoted. Swing-Out, Swing-In, Bi-Fold, Sliding, and Pivoted. To ensure the best performance of steel windows, proper installation is critical. Please be sure an experienced steel window installer & glazier are utilized. OWM will provide our ‘Installation Manual’ upon request. Yes, however, with the advancement of today’s technology it would be impossible to compete with the performance, paint, hardware, energy codes & warranties of current steel window applications. There is a wide range of window and door products available in the marketplace. Therefore, to obtain true comparatives between steel and other window materials, contact an OWM representative. It is important for buyers and specifiers of steel windows to know that these products can meet and exceed the required performance standards and codes.
