Modern uPVC Window Security
Modern uPVC windows are designed with security built in from the outset, giving you confidence without affecting the look or ease of use. Multi-point locking systems secure the sash at several points along the frame, making it far more resistant to forced entry than older single-lock designs.
Reinforced frames, robust hinges, and secure glazing options such as internal beading and laminated glass all work together to create a strong, dependable barrier.
he result is a window that feels solid, closes tightly, and provides a reliable level of protection as part of your overall home security.

Are uPVC windows thermally efficient?
Quality uPVC windows are designed to provide strong thermal efficiency, helping to keep heat inside the home and reduce energy loss.
Modern frames use multi-chambered profiles that trap air and act as insulation, while double or triple glazing adds further protection against heat transfer. When combined with effective seals around the frame, this helps to reduce draughts and maintain a more consistent indoor temperature. The result is a more comfortable living space and improved energy performance throughout the year.

How long do aluminium windows last?
uPVC windows are designed to last for many years, typically around 20 to 30 years depending on the quality of the product and how well they are installed.
They are guaranteed for 10 years but we've been installing windows in Stratford-upon-Avon for nearly 40 years and we know we have some very old windows out there still doing well.

,The material itself is resistant to rot, corrosion, and weathering, so it holds up well in changing conditions without the need for regular treatment. Modern frames and glazing units are built to maintain their performance over time, although components such as seals or handles may need occasional attention. With basic care and cleaning, uPVC windows can continue to look good and perform reliably for decades.
Are uPVC windows cheaper than Aluminium?
Yes, aluminium windows are more expensive and justifiably so. The cost of materials and manufacture is very much higher.manufacturing
Aluminium windows are generally positioned as a premium product, so the initial cost is higher than uPVC.
However, the value becomes clear when you look at the full picture. The strength of aluminium allows for slimmer frames and larger glass areas, improving the overall design and view from your home.
Combined with low maintenance and long lifespan, aluminium often proves to be a better long term investment for those who want quality and performance rather than just the lowest upfront cost.
Is Finance Available for uPVC Windows?
Yes. Prior Products offers flexible finance options including 0% interest finance to help make premium quality uPVC windows more accessible. This allows you to spread the cost of your new aluminium windows and doors up front over manageable monthly payments rather than paying the full amount upfront.
Finance can be a convenient way to invest in improving your home’s energy efficiency, comfort and appearance while keeping control of your budget. Our team will be happy to explain the available options and help you find a payment plan that suits your circumstances.
If you would like to learn more, you can discuss finance during your home survey.
Can uPVC windows be customised in different colours and styles?
uPVC windows give you far more control over the final look than most people expect.
Colour is only the starting point. Alongside standard options like white, black, grey and anthracite grey, there is a much wider range of finishes available, including textured, metallic and more subtle tones that sit comfortably on both modern and traditional homes. Dual colour is also an option, so the inside can suit your interior while the outside works with the overall building.
Style and configuration are where aluminium really stands out. You can choose classic casement windows, fixed glazing for uninterrupted views, or larger feature windows that bring more light into the home.
What is the difference between uPVC and PVCu?
PVC stands for Poly Vinyl Chloride , which is a very lightweight and robust material, making it an extremely popular choice for windows, doors, and conservatories. The “u” simply stands for “un-plasticated”, which means that the plastic is not softened during the manufacturing process, ensuring that it keeps its strength.
With that in mind, you might have already figured out that uPVC and PVCu must be the same, as they both stand for “Un-plasticated Poly Vinyl Chloride”! Installers and manufacturers may use both interchangeably to refer to the same product.
