Heritage Flush Casements
Ruislip Windows and Doors Ltd. Installers of double glazed windows, doors and conservatories.


From Deceuninck, the well renowned global systems company, Ruislip Windows are pleased to bring you the Heritage uPVC flush window. Designed to replicate the appearance of timber, Heritage Flush casement windows are distinguished by sashes that close into the frame and finish flush with the face of the window. Flush casement windows typically have frames that appear the same width, known as “equal sightlines” - this look is achieved using dummy sashes, something that undoubtedly improves the overall appearance of your property.

The Heritage Window and Door Collection combines the elegance and styling of traditional timber flush windows with all the benefits of PVC. Rated A+ they are virtually maintenance free and keep the warmth in and unwelcome visitors out.

The collection is ideal for period properties and for those who want to add or restore character to their homes with its unique, unrivalled, aesthetics and sympathetic symmetrical design giving a property perfect balance and harmony.

The Flush Sash dual seal is exceptionally watertight, with the added benefit of concealing any hardware. Any water is quickly evacuated due to the intelligently designed integral drainage gutter.


There’s no compromise when it comes to security even down to the useful night vent locking position. The bespoke locking keep which caters for this also helps to achieve enhanced security accreditation PAS24, a British Standard all Heritage products have achieved.

This means Deceuninck Heritage 2800 casement windows and residential doors can carry the Secured By Design badge of approval, a national UK crime prevention initiative, which helps protect you and your property for complete peace of mind.

Our wide range of modern, contemporary and period style windows incorporate the latest built-in safety features, including internal glazing beads and multi point locking systems.


Heritage uPVC flush windows look great in all homes, from country cottages to modern townhouses. Their subtle charm and elegance will transform your home. If you live in a Conservation Area, home improvements such as replacing your windows and doors will require planning consent as there are strict guidelines to ensure that architectural features are preserved.

The Heritage Window Collection has been designed with this in mind; replicating the appearance and style of traditional timber windows with features such as our authentic woodgrain finish, monkey tail handles and Georgian bar options.

Always obtain consent from a planning officer before proceeding with an installation in a Conservation Area.
