Sash & Case Windows

Sliding sash windows are a classic and elegant option for any home. They feature a traditional design, with two vertically sliding panels that can be moved up or down to allow for ventilation. Sliding sash windows are an excellent choice for those seeking to maintain the character and charm of a period home.


They offer excellent energy efficiency and noise reduction, with the sash design providing a tight seal when closed. Sliding sash windows are also easy to operate, requiring minimal clearance when opening or closing, and can be an excellent option for those with limited indoor space.


Homeowners can choose from a range of materials and finishes to suit their desired aesthetic, making sliding sash windows a versatile and attractive option for any home

"Would highly recommend Millar Windows, from measuring up, a competitive price to a slick installation. They came when they said they would, left no mess and most of all we just love our new Windows, patio doors and canopy. Would not hesitate to use them again."
