Thinking about upgrading your windows in Esher? uPVC sash windows are a great option if you want a traditional style without the high maintenance of timber. These windows combine the classic vertical sliding design with modern materials, offering durability, insulation and easy upkeep.
We’ll explain what makes uPVC sash windows ideal for homes in Esher, including how they work, key benefits, how to choose a supplier, and what to expect from the installation process.
What Are uPVC Sash Windows?
Sash windows have a timeless look, often found in period homes. They open vertically by sliding one panel over the other. While traditional sash windows were made of wood, modern versions use uPVC, a durable plastic that doesn’t rot or warp.
uPVC sash windows are designed to look like the original wooden style but come with modern features such as energy-efficient glazing, secure locks and smooth slide mechanisms.
You can choose from single-hung (one movable sash) or double-hung (both sashes move) styles, depending on what suits your home best.
Why uPVC Is a Good Choice for Sash Windows
If you live in Esher and want sash windows that look the part but don’t require constant upkeep, uPVC has clear advantages:
Low Maintenance
uPVC doesn’t need repainting or sanding. Just clean the frames with a damp cloth occasionally to keep them looking new.
Weather Resistance
Unlike timber, uPVC resists moisture and won’t swell, warp or crack. This makes it ideal for the UK’s wet weather.
Thermal Efficiency
Modern uPVC sash windows come with double or triple glazing, low-E glass and warm edge spacers to reduce heat loss and keep your energy bills down.
Security
Most uPVC sash windows include multi-point locks, reinforced frames and child safety catches. Internal glazing beads also make the glass harder to remove from outside.
Traditional Appearance
You can get uPVC frames with woodgrain finishes and authentic features such as Georgian bars or sash horns to match the style of older properties in Esher.
Long Lifespan
With proper care, uPVC sash windows can last up to 30 years or more. They won’t rot, fade or rust like older timber frames.
