Application

Suitable for any residential, commercial properties and conservation areas.

Description

The conservation spring sash window is a modern-day alternative to the cord and weighted box sash window. It uses a concealed spring-loaded mechanism instead of the cords, weights and pulleys found in a traditional sash window, this has the advantage of allowing for a smaller structural rebate or installation into a flush reveal.

As part of the Conservation range, our spring sash windows offer a choice of frame profiles and glazing bars, along with a variety of double glass unit depths and specifications to ensure that your aesthetic, thermal and acoustic requirements are achieved.
