Unlike older wooden windows, our flush sash windows will trap heat in your Colchester home throughout the year. The multi-chambered uPVC profile works alongside the panes or double or triple glazing. This helps to trap pockets of warm air in your Essex home throughout the year.

With your flush sash windows trapping heat in your Colchester home for longer, you can rely less on your central heating to warm the property. This means your energy bills will reduce, freeing up money you can spend on the things you want. As less energy is consumed within the property, the carbon footprint of your Essex home will shrink.

The multi-chambered uPVC frame offers a great level of strength and rigidity. When this is combined with the panes of glazing and the latest locks, it creates a high level of security across the whole window.

We fit multi-point locking on our uPVC Flush Sash Windows as standard. This will remove any potential weak points which could be exploited by those looking to gain access to your Essex property. The finest locks are used as standard, providing protection against modern burglary methods. By using Discount Windows & Conservatories, you can have the peace of mind that these windows are protecting your Colchester home and your loved ones against modern burglary methods.



The double glazing installed in our flush sash windows will help keep loud noises out of your Colchester home. The Deceuninck windows we have boast excellent soundproofing qualities, so you won't be disturbed by the outside world. When you close the window, you can shut off from the world and enjoy your home.

The weatherseals work alongside the glazing and the frame to keep cold draughts and damp out. Even in the strongest Essex weather, you won't find the comfort of your home is disrupted.
