How Much Can You Save on Heating and Cooling with Energy Efficient Windows?
St Clares College
Windows do more than frame a view. They invite natural light, fresh air, and a connection to the outdoors, but they also have a major impact on a building’s energy efficiency. In both homes and commercial spaces, windows can be responsible for 40% of heat loss and as much as 87% of unwanted heat gain. Reducing this heat transfer can make a significant difference to comfort and energy bills. That is why energy-efficient windows are one of the smartest investments you can make.
Why Energy-Efficient Windows Matter
Energy-efficient windows are designed to reduce the amount of heat that passes in and out of a building.
They use clever combinations of glass, frames, and seals to make indoor spaces more comfortable all year round.
Benefits include:
Lower power bills: Less need for heating in winter and cooling in summer.
Better comfort: Rooms stay warmer in winter and cooler in summer.
UV protection: Helps stop furniture and flooring from fading.
Less condensation: Reduces the chance of mould and damp.
Quieter indoors: Blocks more outside noise.
