Save money, improve your home’s value and reduce your carbon footprint when you choose to use energy-efficient products for your home.
Low-E glass is brilliantly engineered to block most UV rays out so your home stays at a comfortable temperature each season.
Intercept™ warm-edge spacer insulates the exterior edges of a sealed unit and can tack on 5% savings on monthly energy costs.
Vinyl window frames are constructed to deliver excellent thermal insulation while sealing out drafts and unwanted weather.
Airtight weatherstripping seals the sides, top and bottom frames of your door to prevent air infiltration.
An insulated polyurethane core provides an additional thermal barrier for better insulation.
Composite frames resist rotting, rusting and warping to withstand constant exposure to the elements.
Decorative and ENERGY STAR-compliant door lites are an integral part in a door system’s seal and thermal performance.
Like a two-way mirror, energy-efficient windows allow visible light to pass through to keep your home well-lit while reflecting long-wave infrared radiation to keep interior temperatures constant. Benefits include:
Window World of Fresno carries a number of replacement doors that offer excellent energy efficiency. From choosing Low-E glass for a mostly glass patio door, to choosing an energy-efficient Therma-Tru® entry door, your energy-efficient options are nearly endless. A few added benefits include:
How much is your monthly energy bill? Slide to determine your predicted savings.
ENERGY STAR is a government-sanctioned symbol for energy efficiency, credibility, sustainability and cost-savings for the consumer. Explore the requirements to become ENERGY STAR-certified below and see what it looks like in your region of the country.
U-Factor measures the rate at which heat flows through an object. 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 Fresno is located in ENERGY STAR’s South-Central Climate category. To maintain certification here, our windows and doors must maintain a U-Value of ≤ .30 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.
Making your home energy efficient is a smart investment into your home. The payoff is not only significant, but also tangible. You’ll reap the benefits in comfortability and cost, as energy-efficient products pay for themselves time and time again.
