uPVC Windows FAQs

Your Questions, Answered Simply

Choosing new windows often comes with a few questions. Here are clear, straightforward answers to the most common queries homeowners ask.

How much do uPVC windows cost?

Prices vary depending on size, style, glazing, and finish. We provide transparent quotations with no hidden costs so you can compare options easily.

How long do uPVC windows last?

Modern uPVC windows typically last 20–35 years, depending on climate and maintenance. Our windows are engineered for long-term durability and performance.

Is there a difference between uPVC and PVC?

Yes. uPVC (unplasticised PVC) is more rigid and durable, making it ideal for windows and doors. PVC contains plasticisers, making it flexible and unsuitable for window frames.

Can modern uPVC windows be fitted to existing wooden frames?

In most cases, uPVC windows replace the entire frame to ensure proper sealing, insulation, and compliance with safety standards. Our sales team will confirm what’s appropriate for your home.

How secure are uPVC windows?

Very secure. Our windows include multi-point locking systems, reinforced frames, and high-performance glazing to meet stringent safety requirements.

What is the difference between uPVC and aluminium windows?

uPVC offers excellent insulation and affordability, while aluminium provides a slimmer, architectural look with exceptional strength. Both deliver strong performance—the right choice depends on your design goals and budget.
