inoview™ Thermally Advanced Premium Windows

Chelsea Building Products introduces their innovative window platform, inoview. Utilizing a collaborative design process, Chelsea has created an advanced window system with optimal thermal and structural performance.

inoview’s unique multi-hollow profiles enhance the thermal, structural, water, air and sound performance. Multi-hollows align within the mainframe and sash to offer superior weld strength and thermal efficiency. inoview was designed to maximize thermal performance without the need for exotic insulated glass or foam filling. inoview was engineered to achieve .14 U-Value as well as light commercial structural ratings.

inoview’s design provides a clean, low-profile, classic appearance. The robust product line includes coastal impact models. It’s available with a variety of accessories to produce multiple configurations for residential, light commercial, remodeling, and new construction market needs.

Chelsea’s inoview was designed to accommodate the latest window hardware available. Interior and exterior lamination options allow for further design possibilities and increased marketability.
