High performance uPVC sash windows in North London & Essex
A classic window style, sash windows have been used in properties for hundreds of years. Our uPVC sash windows are a perfect like-for-like replacement for North London homes, made to the same measurements as traditional sash windows for added authenticity.
Complete with sash horns and deep cills for enhanced heritage aesthetics, our sash windows can help to add a touch of traditional elegance to any property.
A great value alternative to timber sash windows
Our uPVC sash windows are a great value alternative to expensive timber sash windows. What’s more, they’re also easier to maintain: a uPVC sash window only requires the occasion wipe down with a cloth and will never need painting. This makes them perfect for homeowners who want an easy-to-maintain window.
Available in a range of authentic wood tones
As well as White sash windows, our windows are available in a range of authentic woodgrain colours and finishes, including Golden Oak, Rosewood and White Woodgrain. There’s sure to be something in our extensive range of colour and foil options to help you seamlessly match your sash window to your property.
A-rated for energy efficiency as standard
At Dolphin, all of our sash windows are A-rated for energy efficiency. This means that they have excellent thermal retention and can help to keep a home warm for longer. This can potentially help you to reduce the amount of energy you use, saving you money on your heating bills. We even offer the option of acoustic glazing so that you can add further acoustic insulation to your property, and keep out unwanted noise.
