Energy-saving tips for your home: Windows, doors and beyond

How can we save energy in the home? It’s a question couples and single occupants alike are asking more and more, as costs rise and carbon emissions stay firmly in the spotlight.

With the benefits of energy saving clear for both your wallet and the planet, we’ve put this guide together to show you simple ways to make your home more efficient.

Truth be told, the quickest way to cut heat loss is by looking at your windows and doors. Old frames, single glazing and hidden draughts let warm air escape and cold air creep in, forcing your boiler, radiators and electric heating to work harder. That means more energy, higher electricity bills and a bigger carbon footprint.

At Amazing Glazing, we’ve spent over 15 years helping homeowners use smart home improvements like double glazing, uPVC frames and composite doors to lower energy bills, use less energy and enjoy warmer, more comfortable homes.

Explaining what makes a product thermally efficient

Thermal efficiency simply means how well a product stops heat from moving from one place to another. In your home, it’s about keeping heat inside during winter and outside during summer.

Thermally efficient windows, doors and insulation:

  • Reduce heat loss
  • Cut the amount of energy your boiler or heat pump needs
  • Lower energy bills
  • Reduce carbon emissions

Financially, this means you spend less on heating and hot water. Environmentally, it means your home’s energy efficiency improves and your carbon footprint shrinks. Small changes, like better glazing or draught-proofing, can go a long way.

How home improvement products can help you to reduce your energy consumption

Windows, doors and insulation are the frontline of your whole house against heat loss. If they’re poor quality or worn out, your heating system must use a lot of energy just to keep up.

uPVC materials

uPVC is the UK’s most popular material for windows and doors, and for good reason. It’s made from a strong plastic that doesn’t rot, warp or crack like timber.

uPVC reduces heat transfer because:

  • It has built-in chambers that trap warm air
  • It doesn’t conduct heat easily
  • It seals tightly against frames to stop draughts

Alongside energy efficiency, uPVC is:

  • Low maintenance
  • Highly secure
  • Affordable
  • Available in many colours and finishes

Double glazing

Double glazing uses two panes of glass with a sealed gap between them. This gap acts as insulation, slowing heat loss.

The Energy Saving Trust states that high-quality modern double glazing can save around £140 a year on energy bills in a typical home. That’s less energy wasted, lower energy bills and better comfort all year round.

Composite front doors

A composite door is made from several materials, usually a solid core, strong frame and tough outer skin. This layered build makes it far more insulating than older timber, or thin aluminium doors.

The Energy Saving Trust estimates that switching to an energy-efficient front door could save up to £200 a year on energy costs. It also cuts draughts, improves security and reduces outside noise.

Draught proofing

Draughts around doors, windows, letterboxes, chimneys and loft hatches let warm air escape. Draught-proofing seals these gaps so heated air stays inside.

Simple fixes can:

  • Reduce heat loss
  • Lower heating costs
  • Make rooms feel less chilly

Conservatory insulation

Many conservatories lose a lot of energy. In winter, they’re freezing, in summer, they overheat.

Insulation systems like ThermaWrap, fitted by Amazing Glazing add multiple layers inside the roof to:

  • Reduce heat loss by up to 91%
  • Lower cooling costs in summer
  • Cut heating bills in winter
  • Make the space usable all year round

Can new windows really reduce my energy bills?

Yes. By reducing heat loss and stopping draughts, modern windows mean your boiler, radiators or electric heating don’t need to work as hard. This lowers the amount of energy you use, helping to cut energy bills, reduce carbon emissions and make your home more comfortable every day.

Quick energy-saving tips beyond windows and doors

  • Use a smart thermostat or programmable thermostats
  • Lower flow temperature on your boiler
  • Shorten shower time and reduce the amount of water used
  • Only run your washing machine, dishwasher and tumble dryer on full load
  • Turn appliances off at standby to avoid vampire energy
  • Use loft insulation or mineral wool insulation
  • Make small changes with kettles, fridges, TVs and game consoles
