Increasing your home’s energy efficiency allows you to save money and the environment—without sacrificing an amenity.
Low-E glass is brilliantly constructed to minimize the amount of UV rays and unwanted temperatures into your home.
Our Duralite spacer system has no metal so the glass edge is up to 45% better insulated against energy loss.
Vinyl window frames are constructed with a complex array of compartments to help trap and repel unwanted weather.
Airtight weatherstripping seals the sides, top and bottom frames of your door to prevent air infiltration.
Insulated polyurethane core provides an additional thermal barrier.
Composite frames resist rotting, rusting and warping to withstand constant exposure to the elements.
Decorative and ENERGY STAR-compliant door lites that allow light in but keep the elements out.
In most instances, your windows come standard with the ENERGY STAR®-qualified SolarZone™ insulated glass package.
Window World of Connecticut’s replacement windows are already designed for superior thermal performance. By choosing our SolarZone™ Insulated Glass Package, featuring the Duralite® spacer system, you can help reduce your energy costs even more, while helping cut consumption of the fossil fuels that pollute our environment.
Since over 80% of a window is glass, substantial heating and cooling savings come from improved glass performance.
The result: your monthly utility bills will reflect savings year round and that should help make you even more comfortable.

ENERGY STAR is a government-sanctioned symbol for energy efficiency, credibility, sustainability and cost-savings for the consumer. Browse below to explore what’s required to become ENERGY STAR-certified and what it looks like in your region of the country.
U-Factor measures the rate at which heat flows through an object. For all window products, the National Fenestration Rating Council (NFRC) tests and assigns a U-Value rating. The lower your U-value, the less heat your windows allow through them.
R-Value determines how well the insulation inside your window is performing. The higher your R-value, the better insulated your window is.
Window World of Connecticut is located in ENERGY STAR’s Northern Climate category. To maintain certification here, our windows and doors must maintain a U-Value of ≤ .27 and an R-Factor from 13 to 21.
Low-E (low-emissivity) glass has been treated with a microscopic metallic coating designed to filter the amount of UV light that enters your home. By filtering the amount of UV light that enters your home, it keeps the heat gain lower in warm seasons and allows more heat in during cooler months. This keeps your home’s temperature more consistent year-round. By filtering out UV light, low-E glass also prevents fading on your furniture and window treatments.
U-factor measures the rate of heat transfer and how well a window insulates. It is measured on a scale from 0.20 to 1.20. The lower the u-factor, the more effective the window is at insulating.
R-value refers to a building material’s insulation level. Each region of the US has an energy-efficient r-value range for windows based on that area’s climate.
Argon is an extremely dense colorless, odorless gas with very low thermal conductivity. It is used as insulation between double-pane and triple-pane windows. When paired with Low-E glass, it keeps the window closer to room temperature, helping eliminate drafts and increase energy efficiency.
Spacers are placed between double and triple-panes of glass. In the past, they were mainly made of aluminum, which we no longer recommend due to its poor insulating properties. Our Intercept™ warm-edge spacer system extends the shelf-life of window glass by reducing condensation build-up and edge-to-glass temperatures. Designed to seal in escaping heat, this spacer system is the most effective on the market.
When it comes to making your home energy-efficient, there really is no risk. The payoff is not only significant, but also tangible. You will reap the benefits in comfortability and cost, as energy-efficient products are an investment that pay for themselves time and time again.
