Understanding U-Values – What They Mean For Your Home & Sash Windows

[wtr-time]

U-values measure how much heat is lost through your home’s windows and doors. The lower the U-value, the better thermal performance the window or door offers and, in turn, the more energy efficient your home will be.

A high U-value means that more heat is lost, resulting in higher bills for heating and cooling your property because more energy is used to keep conditions inside comfortable. Over time, this can soon add up in terms of cost and environmental impact from burning fossil fuels such as coal or oil to generate electricity to power domestic heating systems.

Replacement sash windows typically have an impressive low U-Value rating of 1.4 W/m2K due to their multi-layer glazing system, which traps air within it – slowing down heat transfer from warmer areas like inside your room to colder spots like outside walls. This helps retain warmth where you want it while providing excellent insulation.

You can also introduce secondary double glazing into older wooden window frames as an additional way of modernising them with improved thermal efficiency if noise pollution is an issue you would like addressed on top of more significant energy savings. Doing so will generally reduce u-values further still by creating yet another obstacle between external elements causing drafts and cold air ingestion and the climate-controlled indoor living space of your property, reducing thermal transgression even further, meaning less reliance on costly heating methods during colder weather periods throughout both winter AND summer seasons effectively lowering utility bills accordingly.

Energy efficiency can reduce your heating bills and become more environmentally friendly. With sash windows offering greater thermal efficiency alongside a long-lasting design aesthetic, they are an ideal choice for anyone looking to make their home more energy-efficient and cost-effective.
