So, two windows might have the same U-Value, but transmit heat at different rates because one is a different size to the other. The lower its U-value, the better an insulator the window will be. For example, not every glass panel is manufactured to the exact same standards, and what stacks up in a laboratory might not translate into the real world.

To comply with building regulations, windows like every other element of your property must meet a certain minimum U-value. Double-glazed windows, filled with argon, are typically 1. The British Fenestration Rating Council provide a colour-coded rating system to help homeowners distinguish between different qualities of window. Good windows which keep the heat in are rated A or above.

Bad ones are related E or below. Triple-glazed windows are more effective insulators than their double-glazed counterparts. That said, there are a few drawbacks to consider. Putting to one side practical considerations like these, there are a few instances where a triple-glazed window might not be as good a choice as its U-value might suggest. This is because of heat gain, or a lack of it. As such, south-facing windows which receive direct sunlight might be better suited to double-glazing than triple-glazing.

Generally speaking, the lower the U-value, the better. The U value can be adopted for any kind of home construction and measures how effective that component is at retaining heat. Importantly, the lower the U value, the more proficient the window is at saving energy. Double glazed windows and double glazed doors will have a much lower Uvalue than standard single panes.

What are the benefits of measuring double glazing with the U-value? Measuring single or double glazed windows will highlight where in your home heat loss is increasing your energy bills. Pre-construction calculations are entirely theoretical and based on material characteristics and product design.

Post-installation calculations are the most comprehensive and take into account the workmanship of the installation alongside the product quality. Typical u values for windows that are double glazed record a U-value of between 1. When measuring U value requirements it is important to consider the entire window unit frame, glass, air gaps, etc and not just the glazing, to get an accurate calculation. In the 21st century, the drive to create a more sustainable society means that thermal efficiency is more important than ever.

By installing high performing, thermally efficient windows, you are doing your bit to protect the environment for future generations. The lower the U-values of your windows, the bigger the reduction in your carbon footprint. At Shelforce, we manufacture all our windows to the highest possible standards.
