Mulled Window and Door System

Mulled Window and Door System

by Solar Innovations, Inc.

Many applications, both residential and commercial, utilize doors, windows, and curtain walls in a single unit. There are many limitations, restrictions, and sizes that produce results that look uniform, but lack quality. Solar Innovations, Inc. offers mulled windows and doors to combats these issues and provides customers with a well designed, quality product. The Mulled Window and Door System is designed to maximize flexibility, by joining a series of operable windows and swing doors, to create a cohesive system. The systems maintain consistent sight lines, without additional rafters or framing.

Flexibility is a distinguishing factors of any Solar Innovations® product. This new innovation provides end users with unique selections and flexibility in design, by integrating awning, casement, hopper, fixed, Tilt Turn, and egress windows (depending on local code) into one unit. Solar Innovations, Inc.’s mulled windows and doors allow the combination of as many doors and windows as desired, without additional framing. Units typically stay below 12’ in height, but can be as wide as the customer specifies. The 4-inch site line creates a modern, sleek, customizable option for any project. Single terrace doors and French doors are capable of integration into the same system, as well.

Another exclusive feature Solar Innovations® provides to customers is the ability to select both in-swing and out-swing windows within the same system. Solar products are capable of being hinged left or right. Half of the casement windows can open left and the other half right; this can also be accomplished with doors. Terrace doors can incorporate active and passive door panels; limiters and hold open options are also available. In-swing and out-swing terrace doors, with ADA compliant sills, can be mulled into the window system. Two, three, and five point locks can be utilized, depending on dimensions.

Solar Innovations, Inc. expects to obtain Energy Star product approval during 2011 as it provides superior thermal performance, in part due to the insular technology. Initial testing of the mulled windows and doors, with 1 ½ to 1 ¾ inch insulated, triple-pane, low-E glass provided a U-value of .34 and a solar heat gain coefficient of .25, much better performance than a traditional, double-pane window.

Solar Innovations, Inc. manufactures mulled window and doors in Pennsylvania; units are built to fit custom dimensions and specifications. In-house engineers ensure products will withstand wind speeds, DP pressures, and structural capacities. Solar Innovations, Inc.’s products are constructed out of durable thermally enhanced aluminum, which will not rot, rust, warp, or require constant finish maintenance. Seven standard finishes are available along with two anodized finishes. Custom colors are also available, for an additional fee. Solar Innovations, Inc. is also able to source nearly any glass on the market including low-E, decorative, laminated, and tinted glass options. This increases customers’ abilities to control performance, light transmittance, and overall project design. Snap in nailing flanges have been incorporated into the frame for ease of installation where possible.

The knowledgeable staff at Solar Innovations, Inc. can work with contractors and architects to facilitate proper installation, no matter where the project is located. Please call Solar Innovations, Inc. at 800-619-0743 to talk to a customer service representative.
