Heritage Flush Windows

From Deceuninck, the well renowned global systems company, Ruislip Windows are pleased to bring you the Heritage uPVC flush window.

DECEUNINCK HERITAGE uPVC FLUSH WINDOWS

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.

Style and Performance

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.

Conservation

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.

Security

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.

Every home is different, and our beautiful range of colours takes its inspiration direct from nature to harmonise perfectly with your home and its surroundings, ensuring it stays looking good for years to come.

Our unique range of woodgrain foil colours are available in a number of colourways, including the option of dual colourways – with a foil on the exterior and a different colour or foil on the interior (to match interior decoration).

Premium woodgrain foils in 26 colourways

Heritage colour collection has been specially designed to help you put together the perfect colour palette for your home.

I have used this company on several occasions for my own property with great results. This time, they fitted a new front door for my sister and were helpful, efficient and professional throughout, ensuring that the locking mechanism worked easily.
Their post-sales customer services is also excellent. Many thanks.

Very happy customer, I had an old bathroom window replaced, the whole experience was first class. Every one turned up on time when they said they would, the sales rep, the surveyor and the fitter, they were all very friendly and professional. The price was very competitive and the window is a very good standard

I’m so glad I found Ruislip Windows and would recommend them to anyone. Honest company, great workmanship, and exceptional aftercare. Any small issues were fixed immediately with no questions asked (they replaced a scratched internal pane and buffed a mark on the frame straight away). Friendly, helpful, and reliable in a market where trust matters. Couldn’t recommend them more.

I am delighted with the installation of the new double glazed bay windows in my home. The windows are very smart and the team who did the installation were excellent. The price was good (in the middle of 3 quotes I had) and the work carried out neatly and cleanly. I have the minimum of touching up to do in one room. I am very pleased and would heartily recommend Ruislip Windows & Doorsl

Our windows were fitted by Ross and his colleague. Both were professional and friendly and completed the job in the time given. The job was completed to a very high standard. The windows look great. Everything was left really clean and tidy, they even put our blinds back up for us. The process before hand - getting a quote and getting booked in was easy and quick. Overall really impressed with the service and wouldn’t hesitate to recommend to others. Thank you!

We contacted Ruislip windows and doors to fix a broken window pane at our house. They provided a competitive quote and fixed the pane within a short space of time. They were courteous and provided an excellent level of service. We will be sure to use them when needed again and recommend them to everyone.

I have not had a chance to visit the property however my tenants are impressed by low sound levels and warmth. I asked the tenants to send me the photos of the new windows are installed. I am very happy with the service we received when me and my daughter visited their showroom/offices in watford. The service was excellent from start to finish. I will definitely use the company again and will recommend to my friends and family.

We contacted Ruislip Windows and Doors to get a quote for replacing a few windows. They were very responsive and sent someone around to look at what we needed. The salesman was really helpful and knowledgeable. He didn't try to pressure us into anything which we greatly appreciated. Overall a great experience, would definitely recommend!

We contacted Ruislip Windows about replacing our porch and was pleased to find they could fit new front, side panels and trim and use the original roof and frame. The whole process from Mark visiting to discuss what needed doing to Rob and Ryan fitting the new parts was excellent, all old parts were removed same day and everything was kept clean and tidy. Rob's eye for the finishing details was second to none.
We have used Ruislip Windows before and would recommend them to anyone that asked.
Thank you to everyone we spoke to, we are well pleased with the final item.

The surveyor was very helpful when he came to measure up and advised us on the types of installations available and when we could expect the installation of our doors and windows.
We received a text, within the period advised by the surveyor, asking us when would be a convenient time for the installation.
On the day of the installation the first fitter arrived early in the morning and started removing the old windows and doors. Soon after a second van arrived with the replacement doors and windows and installation commenced. The men worked non stop and completed mid-afternoon. The surrounds of doors and windows were repaired where necessary. The old fittings were removed and all the rubbish swept up and cleared away.
We were shown how the locks and the internal blinds worked.
Overall we are very satisfied with the new doors and windows and the workmanship of the fitters. We would certainly recommend Ruislip Windows and Doors Ltd to anyone.
