Two Different Jobs
New construction gives you open walls and perfect timing. Retrofit means working around occupants, finishes, and weather—usually one unit at a time. Each demands a different product strategy.
When Retrofit Makes Sense
- Existing frames are sound and worth preserving
- Occupants cannot be displaced for extended periods
- Budget and schedule favor pocket or insert replacement
- Historic or protected facades limit full tear-out
When New Construction Wins
When frames are deteriorated, when performance targets are aggressive (passive house, net-zero), or when the design changes the opening entirely, full new construction delivers the best result. Factory-fabricated VITRIUS systems are engineered for both paths—with accurate dimensioning and hardware schedules that make replacement projects predictable.
