uPVC Stacker windows by Enertec offer similar benefits to stacker doors and create a larger opening area due to the way each window sash stacks.

Stacker windows provide two thirds of the total space as open space when fully open and are available as single stackers or double stackers.

Enertec’s uPVC Stacker windows are extremely energy efficient, maintenance free and help provide a peaceful interior thanks to their ability to block outside noise.
