Core Sashed WIndows

Core Sash windows are a London based company specialising in both replacement and repair of traditional, timber-framed double glazed windows and doors.

With London being notorious for its strict conservation rules they are experts at providing products that will let you enjoy all the benefits of a modern double glazed replacement without compromising the traditional sash window aesthetics!

Their double glazed sash windows are specifically designed to closely match the more narrow profiles typically associated with their single glazed counterparts. The replacement will be like-for-like and the appearance of your beloved home will be unaffected.
