Understanding Window U-Values And Energy Performance

Investing in replacement windows with low U-values will drastically increase the overall energy performance of your home. This is one of the leading reasons for homeowners to replace their old windows as they can enjoy lower utility costs at the end of each month.

It’s important that you opt for replacement windows with a low U-value. The U-values of a window gives an indication of the thermal performance of the materials. You should aim for a minimum U-Value of 1.1 w/m2k for casement windows and 1.3/1.4 w/m2k for sliding sash windows. Marvin Architectural can reach U-Values as low as 0.65 w/m2k for homeowners seeking a superior energy-saving window solutions. A word of warning, some window companies advertise just the glass U-value and not the overall window U-value. You should always make sure that you’re reading the overall window U-value which is indicated by w/m2k.

As well as U-values, you should also pay close attention to the airtightness rating of your replacement windows. The Air-tightness rating of a window isn’t just an indicator of its energy-efficiency, it’s an extremely important sign of build quality. Windows with poor air-permeability will quickly result in unwanted air-leakage and condensation within your home

The CE marking indicated by your window & door supplier makes sure that your products are consistent with their Declaration of Performance. It also provides you with a reliable way to determine a window’s energy properties, build/design quality and to compare different manufactured products.
