WINDOW reproduction


 

reproduction of traditional double hung wood sash for insulating glass

Reproduction is recommended when half of the sash parts are broken or missing, existing sashes are not originals and are not proper reproduction, a new opening has been added to a façade where traditional windows are present, or insulating glass is required and sashes are only 1 3/8" thick.
