Greta Thunberg is reminding the world that we all need to do more to reduce our impact on the global climate. Burning less fuel is one way to do this, but turning the gas down is not an option unless you want your Essex home to feel like an ice cave. But, by insulating your home better you can reduce the need for gas heating, and as much of the heat is lost through windows, it makes sense to upgrade old windows with new energy efficient ones.
Gone are those times when the function of a door and window was limited to being the source of fresh air and natural light. Today, windows and doors have gained much importance as a very crucial energy-saving component in the house. An energy-saving window is the one that reduces the use of artificial cooling or heating. Technological advancement has made it easy to have windows that are insulated against heat and cold.
There are a few things that will make your home windows energy saving and help you to save money. A window turns out to be energy efficient when it has various window glass panes like double or triple-paned, quality frames, krypton or argon gas between the window panes, low e-glass coatings, and windowpane spacers. All these energy-saving features help to curate that perfect window.
Some benefits of an energy-efficient window include:
Less condensation- Energy-efficient glazing minimizes condensation build-up on windows.
More comfortable environment- The energy-saving glazing reduces the loss of heat through windows, and thus it means fewer cold areas and draughts.
Less noise- Not just do these windows keep away the heat; they insulate your entire home against noise from outside too.
Types of energy-efficient options
Low emissivity or low e glass uses a transparent coating to reduce the heat that passes through the glass. But it doesn’t mean that light cannot pass through it. This almost invisible coating minimizes the U value of the glass. Lower the U value, greater is the resistance of the window to heat flow and thus, better is the insulating value.
To go well with the glazing system, the frame with low U value helps in reducing the window’s U value. Frames that use uPVC, timber or composite aluminium outperform the standard aluminium windows as they provide great thermal performance.
Double glazed windows
The perfect energy-saving solution is to minimize all types of heat transfer; double glazing in Essex is great for high-performance windows in all types of climates. When combined with the low-e glass on one pane at least and argon gas, these double glazing windows offer the right thermal performance.
Cool and hot air can easily escape or enter your space through cracks and gaps around the frames and sashes. A good window seal is important to improve the energy-saving performance of the windows. Traditionally, the windows with compression seal tended to have great air infiltration results. But recent advances for seals in the slider windows have improved considerably.
How do energy-saving windows work?
- A cold draft is surely a sign of inefficient window, but the cracks or gaps in and around the window are not the reasons that drafts can be there. While a well-fitted window is highly important, so are the actual materials that make the frames and panes.
- Through conduction, the heat gets transferred through the window only. During winters, this means that the heat generated by HVAC is lost directly through window panes and frames.
- For better energy-saving and also to preserve heat, these windows are made of components that have high insulation value. Features involve various panes of efficient glass with a reflective coating.
- When warm air gets in contact with the cold windowpane, it gets cooled, and the air then sinks while warm air from home rises to take its place. This then creates a kind of cycle of the rising warm ain and sinking cold air, creating a cold draft.
Other benefits of energy-efficient windows
Energy-saving windows are great at reducing the overall noise pollution. A lot of homeowners also report that around 60 to 75 percent of outside noise is reduced with the installation of IGUs in the homes. Also, the low-e coatings on the windows help to reduce the sun damage to your favourite carpets, furniture or even some personal items by about 75 percent.
So, this is all about energy-efficient windows and how they help to keep your home environment welcoming and vibrant.
