Heat loss through windows can increase your energy bills by 30%. So window replacement with energy-efficient windows will stop this from happening. The energy efficiency of windows is measured by the U-value, which ranges from 0-15 to 0.30. The lower the number the more efficient the window is. The maximum number you should accept is 0-26.
What Are Energy Efficient Windows?
An energy-efficient window is composed of the frame, panes of glass and inert gas between the glass panes. 90% of heat loss through windows occurs through the glass. The most energy-efficient windows contain multiple panes of glass. Each of the components of an energy-efficient window have their roles to play.
- Low-emissivity glass: low-E glass, minimizes the amount of heat and UV light that can pass through it.
- Double glazed windows: these consist of 2 panes of glass and have an inert gas trapped between the 2 panes. It performs twice as well as single glazed windows.
- Triple glazed windows: these consist of 3 panes of glass and give even higher thermal insulation than double glazed windows.
- Argon between glass panes: Argon is a natural, inert, colorless, non-toxic gas, it reduces the ability of heat to be transferred across the gap between the window panes.
- Window frame material: frames that use timber, uPVC, or a composite aluminum and timber design give the highest insulating properties.
Benefits of Energy Efficient Windows
Energy efficient windows provide excellent insulation and keep you warm in the winter and cooler in the summer. This also leads to reduced utility bills. They are eco-friendly and also good at sound insulation. Low E-glass can protect your furniture and sun from fading and sun damage.
