We should know about them better than anyone as we have been a cornerstone of the window industry for a remarkable 40+ years.
There’s a lot more to tell you about the term U-value if it’s something you’re curious to learn about and how it will impact window performance.
So, let’s do just that and turn you into a veritable maestro on the topic of U-values, just like we are.
Why Is A Window U-Value Significant?
It’s not something to be overlooked as what a window U-value represents is the insulating ability of replacement windows.
A design with a low U-value indicates outstanding insulation and a window that will maximise thermal efficiency and ignite warmth indoors.
Windows offering a high thermal transmittance (an alternate word for U-value) don’t manage to provide a great deal of insulation in comparison and are guilty of letting heat pass through them.
The U-Values Of Different Window Types
We don’t think you’ll be too surprised to discover that single glazed windows have a worse thermal transmittance than double glazing and triple glazing windows.
Some single glazed solutions only manage to achieve a U-value of 6.0 W/m²K, which trails way behind a double glazed window, often accomplishing something in the region of 1.2 and 3.7 W/m²K (building regulations currently state that replacement windows must offer 1.4 W/m²K). The finest triple glazed windows are capable of realising a triple glazed unit u-value figure below 1.0 W/m²K.
Unlock Excellent U-values With Energy Efficient Glazing
The best in window performance can only be attained if energy-efficient glazing is present in a window unit.
Anything deemed as energy-efficient glazing does a sterling job of trapping heat in to magnify home insulation. It heavily relies on Low-E glass, which has an invisible coating, there to reflect heat.
Double or triple glazed windows that are complete with energy-efficient glazing are a mechanism for instilling home comfort and will make the cost of energy less of a financial burden.
Pay close attention to U-values when assessing any energy-efficient glazing and also be mindful of privacy, security and sound insulation requirements.
Any windows purchased from James Oliver contain energy-efficient glass as standard, a necessity in our eyes to help customers benefit from top-level home insulation and cheaper energy.
