Our uPVC Windows
Modern uPVC windows deliver energy efficiency and durability across a wide range of popular styles. We manufacture windows in various designs, colours and glazing options — including double glazing with argon-filled units that improve insulation, reduce condensation and cut outside noise.

Sliding sash windows use two gliding panels to blend traditional character with modern performance — delivering energy efficiency, controlled ventilation, enhanced security and smooth everyday use.

Frequently Asked Questions
uPVC windows are frames made from unplasticised polyvinyl chloride — a rigid, hard-wearing plastic commonly used in construction. Among the UK’s most popular window types, they’re low-maintenance, energy-efficient, and available in both traditional and contemporary styles. Modern uPVC is fully recyclable, making it a more sustainable option than older plastic frames.
Also read our guide about the difference between PVC & uPVC.
uPVC windows are well regarded for their affordability, though costs vary depending on style. Each style carries its own features, benefits and aesthetic qualities that influence the final price. Most homeowners can expect to pay between £500 and £1,500 per window — a cost-effective solution for most budgets.
uPVC windows are well-suited to cold and wet conditions. Multi-chamber insulated frames create a tight seal against draughts and water ingress, while advanced drainage channels prevent moisture build-up — ensuring consistent energy efficiency and long-term weather resistance.
Yes — existing uPVC windows can be upgraded with double or triple glazing, multi-point locking systems and insulating seals. RePlace Windows can retrofit your current frames, delivering improved security, energy efficiency and thermal comfort with minimal disruption and cost.
Contact our PVC installers to find out more about our retrofitting service.
When fitted by trained professionals, high-quality uPVC windows typically last between 25 and 35 years. Resilient frames resist warping, fading, peeling and rot thanks to their inherent weather-resistant properties.
Regular upkeep is straightforward — wipe frames with a damp cloth and lubricate moving parts to maintain smooth operation and preserve their appearance.
