About uPVC windows

uPVC casement windows in a South Wales home

uPVC (unplasticised polyvinyl chloride) windows are durable, low-maintenance and cost-effective. They don’t rot or need painting, and with modern double or triple glazing they help keep your home warmer and quieter. We supply and fit made-to-measure uPVC windows across Newport, Cardiff and South Wales.

Rehau casement windows

We install Rehau casement windows — a leading system known for strong frames, good thermal performance and long-lasting hardware. Casement windows open on hinges (side or top) and seal tightly when closed, so they suit both modern and traditional homes. Rehau’s range includes multiple colours and finishes to match your property.

Wood-effect uPVC flush casement window

Flush casement windows

Flush casement windows have the opening sash sitting flush with the frame when closed, giving a cleaner, more traditional look similar to timber. They’re a popular choice for period or character properties where you want the aesthetics of wood with the benefits of uPVC — no painting, no rot and better energy efficiency.

Sliding sash windows

Sliding sash (sash) windows have two moving panels that slide vertically. They give the classic look of traditional box sashes but in uPVC, with double glazing and modern draught-proofing. Ideal for terraces, Victorian and Edwardian homes, or anywhere you want that period style with minimal upkeep.

Windows FAQs

Casement windows open on hinges (side or top). Sash windows slide vertically and give a more traditional look. We’ll help you choose at survey.

Yes. We can quote for triple glazing where it’s suitable for your property and budget.
How long does installation take?
Most standard window replacements are completed in a day. Larger jobs may take longer; we’ll confirm when we schedule.
