Why we use it
BCG treats window selection and installation as a combined design and building-science decision.
Character
Sightlines, muntins, profiles, hardware, glass clarity, and exterior trim all affect the final composition.
What we look for
Performance data, water ratings, profile proportions, installation requirements, lead times, and service support.
Design considerations
Window rhythm, casing, sill depth, screens, hardware, and glass selection should be coordinated early.
Installation considerations
Rough openings, flashing, shims, air sealing, drainage, and sequencing determine whether the unit performs.
Common mistakes
Upgrading the window while neglecting installation, selecting units too late, or ignoring lead times.
Maintenance + aging
Windows should be cleaned, operated, inspected, and serviced according to the manufacturer and exposure.
