Spring Sash Windows

Introduction

The spring sash window is a modern day alternative of the cord & 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 installing 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 specification to ensure that your aesthetic, thermal and acoustic requirements are achieved. 

Finish

RAL Classic Range

Typically in RAL 9003 Signal White but our customers may choose from the RAL Classic swatch.

Colour matching service

On request we are able to offer a colour matching service.

Dual colour finish

We are able to offer a ‘dual finish’ where different colours are desired internally and externally or a ‘mixed finish’ where frames are specified to be contrasting to sashes.

Stain finish

Our products are also available finished with a pigmented stain in a variety of shades to suit your requirements.
