Do you manufacture other types of windows?+

Box Sash hand-crafts timber box sash, sash and casement windows, alongside French doors and entrance doors. The range also includes shaped, feature and heritage work.

Will new windows improve draught exclusion?+

Modern seals and double glazing are used to improve thermal and acoustic performance while retaining traditional proportions.

What guarantees apply?+

Box Sash currently states a 50-year guarantee on qualifying window frames and up to 10 years on glazing units, subject to its guarantee terms.
