SHGC (Solar Heat Gain Coefficient) measures how much heat from the sun passes through a window. A lower number means less heat comes in.
U-Value measures how well a window keeps heat inside. A lower U-Value means better insulation, keeping warmth in during winter and out during summer.

When choosing uPVC top hung windows, price is a key factor, but so is performance. This page provides a direct price comparison between single-glazed and double-glazed options, as well as white vs. coloured uPVC frames, so you can make an informed decision.
A common misconception is that all uPVC windows cost the same, but coloured uPVC frames are more expensive due to additional manufacturing processes. If affordability is your main priority, white single-glazed windows are the most budget-friendly choice. However, double glazing significantly improves insulation, reducing heat loss in winter and keeping interiors cooler in summer. This is reflected in the U-Value—a lower U-Value means better insulation.
Similarly, Solar Heat Gain Coefficient (SHGC) values indicate how much solar heat passes through a window. If you’re looking to improve energy efficiency, a white double-glazed uPVC window offers the best balance between cost and performance, with better insulation and reduced heat gain compared to single glazing.
Use this price comparison to see how uPVC top hung window prices vary across sizes, frame colours, and glazing options. Whether you prioritise affordability, energy efficiency, or aesthetics, this guide will help you choose the right uPVC windows for your home or project.
