Why Your Front Door Matters for Energy Efficiency An old or poorly fitted front door can lose as much heat as a single-glazed window. Modern energy-efficient doors achieve U-values of 0.8-1.0 W/m²K compared to 3.0-4.0 W/m²K for a typical old timber door. Upgrading your front door alone can save £20-£50 per year on heating and […]
