When it comes to replacing your windows, the glass selection can often go overlooked. We don’t believe in that. We believe that the glass you choose for your Extreme window makes a huge difference – so carefully consider the look and visibility you want, be that either complete privacy or a clear, uninterrupted view of the world beyond the window. The Trent Valley Windows team will be on hand to advise you on your journey.

Privacy Glazing – Some windows lend themselves to an extra level of privacy. Ideal for bathrooms or exposed windows, our privacy glazing options mean that you can’t be seen from the outside, whilst simultaneously letting plenty of natural light to pass through. This option is available for both double and triple glazed units.
