Traditional Double Hung Windows

This arrangement is an ageless window type that offers some unique advantages. Sash tilt in for easy cleaning, ventilation is improved by opening the top and bottom sash equally and classic historical appeal is achieved when using Timeline double hungs.

Our traditional window is equipped with advanced energy saving features. For example, Timeline double hung checkrails incorporate the use of interlocks, weatherstrip and high-quality sash locks for a precision fit and easy operation.
