We couldn’t proclaim ourselves to be window experts and it would be frankly weird if we didn’t know terminology like this after an existence in the industry of 150 years.
Sharing our wealth of knowledge, we can tell you a lot more about U-values, handy insight to be aware of when looking into new replacement windows for home.
Read on and let’s make U-values your specialist Mastermind topic.
What Relevance Do Window U-values Have?
They’re very significant, as it happens, as the U-value of a replacement window informs you of how it fares in terms of the level of insulation offered.
A low U-value is a good sign and points to a window that will provide outstanding thermal efficiency and create a much warmer household.
Windows that only achieve a high thermal transmittance (a different way of referring to U-values) symbolise poor insulation and a propensity to let heat escape in considerable volumes.
A Comparison Of U-Values By Window Type
Single glazed windows earn the wooden spoon when pitted against double glazing and triple glazing for thermal transmittance.
The worst single glazing only manages a U-value of about 6.0 W/m²K, while a double glazed window will typically achieve around 1.2 to 3.7 W/m²K (building regulations state that replacement windows must accomplish 1.4 W/m²K). Triple glazed windows have the capability to hit a triple glazed unit u-value figure below 1.0 W/m²K.
Energy-Efficient Glazing Is The Secret To Great Window U-Values
A replacement window relies on energy-efficient glazing if it’s to perform to the highest insulation standards.
Glass that’s advertised as energy efficient is made to minimise heat loss and provide a huge uplift in thermal insulation. Low-E glass is a chief component of it and contains an invisible coating designed to reflect heat.
When incorporated into double or triple glazing windows, you’re assured of elevated warmth within your house and have an improved chance of making notable energy savings.
Always scrutinise the U-value of energy-efficient glazing and the depth of privacy, security and sound insulation that it provides.
You benefit from energy-efficient glazing no matter which of our window styles you decide to select and can anticipate it positively impacting your home lifestyle and finances.
