The St. Helen’s Suite by Bolger
Not all new wood casement windows have to look the same. They don’t all have to be featureless and functional like the generic windows that have become so commonplace in Ireland.
Introducing The St. Helen’s range of traditional casement windows and surrounds.
Inspired by classic casement windows from the early 20th century, our “St. Helen’s” windows and surrounds will add a wonderful touch of class to your home, and with BENGglas vacuum double-glazing fitted, they will be more energy efficient than triple-glazing.
