What Are Punch Windows?

Punch windows also known as punched openings are individual window units installed within pre-cut openings in a building’s exterior wall. Each unit is framed and sealed independently, offering excellent compartmentalization and flexibility.

These systems are often used in:

Multi-unit residential buildings (condos, apartments)
Schools and universities
Hospitals and clinics
Government and municipal buildings
Offices and mid-rise commercial properties

Planning for acoustic insulation, Low-E glass, or custom grills?
