THE MANY REASONS TO USE STEEL WINDOWS AND DOORS

NARROW SIGHTLINES

No other quality is more readily associated with steel windows and doors than their narrow sightlines. Architects have incorporated this attribute in every sort of building over hundreds of years and have designed the gracefulness of steel windows and doors into countless architectural styles. Ironically, the minimal aspect of steel windows and doors is derived from the incredibly massive strength of the material. The aesthetic virtues achieved by use of steel cannot be duplicated in aluminum, wood or vinyl alternatives. The look of steel windows and doors is not simply distinctive, it is unique.

Next: Strength

STRENGTH

Steel windows and doors are stronger than any alternative material. By direct comparison, they are three times stronger than aluminum. This advantage permits the use of immense glass lights, often in spectacular openings, while maintaining narrow sightlines. Hardware fastened to steel windows and doors will not pull out, and ventilators do not distort or rack with age.

Next: Installation

INSTALLATION

Any building team that has experienced project delays caused by racked, inoperable or otherwise damaged windows or doors can appreciate the relative problem-free installation of steel windows and doors. Almost without exception, steel windows and doors arrive at the job site without the kinds of structural defects associated with alternative materials and can be installed just as economically. Depending on building design, steel windows and doors often add to overall structural integrity.

Next: Historic Replacement

HISTORIC REPLACEMENT

The design flexibility offered by steel windows and doors, together with exceptional durability and life cycle, make steel windows and doors an excellent choice in renovation projects. Original steel windows and doors can be replaced with units which match historically, while offering state of the art finishing pretreatment and factory applied finishes, improved weatherstripping, new muntin designs, and glazing with high performance glass. Steel is often selected to replace wood windows or doors to improve sightlines or provide extended durability. In fact, steel windows and doors can often be designed to recreate the aesthetic feeling of wood, yet provide additional integrity to the structure.

Next: Factory Finishes

FACTORY FINISHES

Modern technology with metal pretreatment processes and top coats enable manufacturers to produce steel windows and doors which will remain virtually maintenance free. Members of the Institute can provide a variety of factory applied, corrosion inhibiting finishes including galvanizing, electro-coat (e-coat) primer, powder coatings, urethane enamels and more. And factory finishes are not just durable, they're beautiful as well.

Next: Fire Rating

FIRE RATING

Steel window and door manufacturers offering fire rated designs provide independent laboratory fire labels with their products. Fire rated windows and doors are not confined to fixed lites. They can be fabricated in a variety of operable designs. (Consult individual manufacturers for specifications.)

Next: Classic Hardware

CLASSIC HARDWARE

o Hardware options are not limited by the nature of the window or door material. Steel windows and doors can accept any style, any type of hardware that can be imagined. Manufacturers have access to a seemingly unlimited variety of handles, operators and closing devices. In addition, exact hardware replacements for windows and doors half a century or older are often available. Just as important, the hardware fastened to steel windows and doors do not tear out or loosen with heavy use.

Next: Special Applications

SPECIAL APPLICATIONS

Steel windows and doors can be designed to meet the most stringent building requirements for both blast resistance and impact resistance. The strength and durability associated with hot rolled steel sections make the product an ideal choice for this special building application. (Consult individual SWI companies for product specifications and testing data.)

Next: Life Cycle

LIFE CYCLE

Because steel windows and doors are inherently more durable than almost any alternative material used in construction, their life cycle is unsurpassed. A benefit of using steel windows and doors is the low total cost of ownership. In Europe, classical architectural examples over a century old contain original steel windows and doors. In North America, steel windows and doors remain highly functional after three generations. Older steel windows and doors are replaced in certain cases only to take advantage of new glazing, finishing or ventilator technology. Properly installed and maintained, steel windows and doors and deterioration are essentially contradictions in terms.

Next: Security Products

SECURITY PRODUCTS

Prison and detention facility designers and planners must meet rigid criteria for window and door performance, regardless of the level of security required for a detention facility. Steel window and door manufacturers who offer detention products have worked together with the architectural community to create windows and doors of exceptional strength without sacrifice to contemporary aesthetic demands and functional requirements such as vandal resistant ventilators. Custom engineering and fabrication permit a wide variety of window and door designs.

Next: Versatility

VERSATILITY

Steel windows and doors have been selected for use in the most contemporary settings, in very traditional structures, and in gothic themes. Steel windows and doors can be used on the building exterior and/or the interior. Several members of the Steel Window Institute also fabricate doors from the same steel window sections. Steel windows and doors have been used in municipal buildings, museums, churches, private homes, commercial buildings, schools and universities, transportation terminals, manufacturing facilities, hospitals and retail stores.

Next: Thermal Performance

THERMAL PERFORMANCE – ENERGY AND SOLAR HEAT GAIN

Today’s steel window and door manufacturer has recognized the importance of energy conservation in the fenestration marketplace and addressed these issues within their industry accordingly. Today’s hot rolled steel windows and doors are designed not only for superior strength and aesthetics but also energy efficiency. Due to their supreme strength, steel window and door profiles have been afforded the luxury of narrow sightline designs which, in turn, mean there is a larger amount of glass available to the architectural design of the building. The larger amount of glass available in the window or door system in combination with today’s high performing glass possibilities, results in an extremely energy efficient solution for today’s energy requirements with steel windows and doors. The naturally low thermal transmission of steel, weatherstripping, double insulating glass with energy efficient coatings and gas filled spaces will provide excellent U-value results for the heating portions of the country and Solar Heat Gain Coefficient values for the cooling portions of the country and everywhere in between. As future building code standards demand tougher energy requirements, steel window and door manufacturers can adapt and utilize triple glazed glass units and thermally broken frames to remain code compliant. Owners and architects have historically selected steel windows and doors for their projects because of their elegant features obtained through strength, unique design theme opportunities available through versatility and their life cycle endurance afforded through durability. Today’s owner and architect can retain all those aforementioned attributes, while receiving the energy efficient solutions they need.
