For homeowners, insufficiently insulated windows can be a serious problem that breaks the family budget and sends precious dollars “out the window” in the form of excessive heating and cooling bills.
When it is warm inside and cold outside, window panes transfer heat by thermal conduction, requiring additional heating to stay comfortable. A similar process occurs when it is hot outside and cool inside. Air leakage through cracked window seals worsens the problem, particularly in harsh weather.
While single-pane windows transfer the most heating and cooling, even dual-pane windows may not tame high utility costs.
Now homeowners are turning to an innovative approach that adds an inner insulating window to existing ones. This can reduce heat loss by 77% or more for single-pane windows and heating/cooling bills by up to 30%, while stopping air infiltration for additional energy savings and comfort.
The added window layer improves insulation beyond that of most double-pane units and also reduces unwanted street noise, creating a more peaceful home.
Cutting Heating and Cooling Cost
Two factors drive energy savings: the window’s insulation value and its ability to block air infiltration.
Glass insulates because of air bubbles adhering to it, which resist thermal conduction. A single-pane window has two bubbles—one on each side. A dual-pane has three. Adding a second insulating window increases this to five when the air space exceeds one inch.
An added window spaced 2–4 inches from the original acts as an insulating layer. A single-pane window’s R value rises from 1.15 to 3.84; a dual-pane’s from 1.81 to 4.40. These gains reduce heat loss by up to 77% in single-pane setups and significantly improve dual-pane performance.
Leaky seals let outside air in, forcing HVAC systems to work harder. Inner windows use spring-loaded stainless steel seals that apply constant pressure, eliminating drafts and maintaining consistent performance. These seals are rated for 50 years, delivering long-term efficiency and comfort.
Silencing External Noise
The same system cuts noise by up to 95% using laminated glass, ideal spacing, and spring-loaded seals to block sound vibration and leaks.
