Maintain a traditional appearance and preserve your Braintree, Chelmsford or Essex property’s classic aesthetics with our authentic sash windows from Master Frame. Our exclusive collection is designed to replicate the style of timber sash windows. Choose from a timeless collection of colours, foils and painted finishes.
A rated, CE marked, and BBA accredited, our double glazed sash windows are manufactured to the highest of specifications. They come complete with a ten year guarantee, and their low maintenance uPVC design will ensure your window will never rot, warp or require re-painting.
We offer a beautiful and varied window collection that features elegant, pioneering designs that faithfully reproduce a traditional timber appearance. Our sash windows offer an authentic look and feel that you won't receive from a simple casement window, maintaining the traditional timber frame style but containing all the benefits of advanced uPVC double glazing.
Slender Sealed Units
Our uPVC sliding sash windows include slender sealed units to allow for deeper internal astragal bars and glazing bead, enhancing the classic timber sash window style. The narrow space between the glazing panes is filled with krypton gas to achieve better heat retention.
For hundreds of years, traditional timber sash windows have been made with vertical joints known as mortice and tenoned. Contrary to standard uPVC windows, our sliding sash windows replicate this traditional method to achieve a truly authentic look.
Wood Grain Effect
To complete the authentic appearance of traditional timber sash windows, our uPVC profiles have realistic timber effect finishes in a variety of different colours. The illusion of timber is produced through a wood grain textured acrylic foil that covers the profile.
