When you are looking for replacement windows, it’s important to consider what type of windows are going to enhance or change the character of your home. Not only are Celestial renowned for being a successful window manufacturer, but we also have the best window fitters to guarantee our customers the smoothest transition possible.


The investment in your property will not only improve with new windows but will also reduce your heating costs and improve the security of your home. Whether your preference is traditional sliding sash or contemporary flush sash, beautiful woodgrain or smooth grey, at Celestial, we can install it all. We’re a window manufacturer that designs and installs various window styles in a range of different colours using only the highest quality locking systems and A-rated glass as standard.


UPVC Casement windows are the most popular. They’re classic and easily tailored to each property, with the sash opening outward. They’re superbly energy efficient whilst still providing air and light through your home.


Sliding Sash windows are the style you would generally see in a period home, where the sash opens upwards as opposed to casement where they open outwards. Sliding sash windows add character to any property and install them in upvc as opposed to the traditional timber. This means that you can have the look whilst also gaining the benefits that come with upvc. 


Our team of professional window fitters are available with years of experience and skills to offer you an efficient installation process.
