Our uPVC Windows
Modern uPVC windows combine popular styles with proven energy efficiency and durability, available in a range of designs, colours, and glazing options. High-quality double glazing — two panes separated by an argon-filled gap — is key to an energy-efficient Glasgow Southside home, cutting condensation and outside noise while suiting most windows and doors.
Casement windows open outward for maximum airflow and flexible ventilation. Built from durable uPVC with strong locking systems, they're designed to handle daily use and Scotland's changeable weather.
Tilt-and-turn windows use multi-point systems to tilt inward for ventilation or turn fully for easy cleaning. They combine versatility, security, and thermal comfort, making them well-suited to high-rise buildings.
Sliding sash windows have two framed panels that slide past each other to open and close. They echo the traditional look while adding modern benefits like energy efficiency, controlled ventilation, security, and ease of use.
Bay windows project outward to bring in extra light, airflow, and space, with a central window flanked by two angled sides. They offer timeless character and remain a popular choice for replacing windows in Glasgow tenements.

Frequently Asked Questions
uPVC windows use unplasticised polyvinyl chloride — a tough, long-lasting plastic widely used in building. They’re among the UK’s most popular window choices thanks to low upkeep, strong energy efficiency, durability, and both classic and modern styles. Today’s uPVC is also fully recyclable, making it a greener pick than older plastic frames.
Valued for their affordability, uPVC windows still vary in price depending on the style chosen. The cost of installing new windows depends on each design’s features, benefits, and appearance. On average, a new uPVC window costs between £500 and £1,500, making them a budget-friendly choice for homeowners.
Built for cold, wet conditions, uPVC windows hold up well. Their insulated multi-chamber frames seal tightly to stop draughts and water ingress, and built-in drainage channels prevent moisture build-up. This delivers strong energy efficiency and long-lasting durability and weather resistance.
