In addition to providing custom windows for historic restoration projects, Pella offers four window replacement systems that provide you with the flexibility to address the unique installation challenges that often accompany commercial window replacement projects
- Pella Precision Fit Window System — fully assembled, factory-tested double-hung window unit that slides easily into the existing sash “pocket” created when the old sash is removed. This is done without damaging surrounding trim, wall paper, paint or plaster. Custom-built units are made to order in 1/4" increments to fit your existing window opening. See Precision Fit Windows on www.PellaADM.com for complete description and options. Pella Frame Expander System — provides an economical method for replacing old wood or metal windows without tearing out existing window frames. Pella aluminum-clad windows and doors have an accessory groove that allows for the use of the frame expander system. Made of low maintenance aluminum cladding that perfectly matches Pella products, these frame expanders can be used to update the exterior trim or cover existing trim that is in poor condition. Windows need to be accessible from the exterior to use this type of installation.
- Pella Standard Subframe System — allows installation of new replacement windows from inside the building. This eliminates the need for exterior scaffolding and its expense, reduces labor costs and minimizes disturbance to existing construction. In most cases, only the sash of existing windows will need to be removed. The extruded aluminum subframe system is pre-assembled and covers the existing window frame and exterior trim, and the new window is set into the subframe.
- Pella’s T-Subframe System — allows for the replacement of old metal windows without the need to tear out existing metal frames. The subframe consists of aluminum components that are pre-assembled and installed into openings, concealing the existing window frame, to become a “receptorrdquo; for the new window. When historic, aesthetic or structural considerations dictate a complete tear-out, Pella can provide custom-size window units to fit into existing openings. Contact your Pella architectural consultant early in the project to ensure close coordination with the architect and contractor, accurate measurements, and timely fulfillment of window and door orders to keep projects on schedule and on budget.
