Understanding Energy Efficiency

The Technology

Science Behind The Savings

Windows
Doors
Siding

Low-E Glass

Low-E glass is brilliantly engineered to block most UV rays out so your home stays at a comfortable temperature each season.

Warm-Edge Spacer

Intercept™ warm-edge spacer insulates the exterior edges of a sealed unit and can tack on 5% savings on monthly energy costs.

Vinyl Framing

Vinyl window frames are constructed to deliver excellent thermal insulation while sealing out drafts and unwanted weather.

Innovative Weatherstripping

Airtight weatherstripping seals the sides, top and bottom frames of your door to prevent air infiltration.

Insulated Core

An insulated polyurethane core provides an additional thermal barrier for better insulation.

Sturdy Frames

Composite frames resist rotting, rusting and warping to withstand constant exposure to the elements.

Energy-Saving Door Lites

Decorative and ENERGY STAR-compliant door lites are an integral part in a door system’s seal and thermal performance.

Insulated Structure

Built with rigid foam insulation to reduce energy loss and reinforce the siding for smoothness and straight lines.

Energy-Saving Barriers

High-density insulation to minimize outdoor noise for a quieter indoor ambiance and loss of wanted heat or air.

Built to Last

Fully rolled over, double-thick nail hem anchors panels to the wall; tested to withstand harsh weather.

Benefits of Energy Efficiency

An energy-efficient home helps you reduce your carbon footprint without sacrificing comfort In warm months, energy-efficient products keep out unwanted warm air. Then in cold months, they help to insulate your home like a blanket, trapping the heat inside and protecting your interior from cold drafts. Energy-efficient products are great for you wallet, your comfort and the environment.

Why Go Green

Energy-Efficient Products

Energy-Efficient Windows
Energy-Efficient Doors
Energy-Efficient Siding

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:

  • 48% reduction in solar heat transfer during the summer months
  • 104% increase in R-value of the glass in winter months
  • Protect your carpet, furniture and draperies from fading
  • The Intercept™ spacer system will extend the life of your windows

Explore Windows

Window World of Central Valley 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:

  • Protection against unwanted temperature changes
  • A properly installed and sealed entry door
  • A durable and sturdy door that keeps your home secure

Explore Doors

We find that many customers have never even considered vinyl siding as an energy-efficient option. However, the 6000 series siding from Window World of Central Valley takes vinyl siding to a whole new level with up to a 1.5 inch-thick foam insulation. A few added benefits include:

  • Protection against unwanted temperature changes, no matter what season
  • Durable material that protects your home from hurricane-force winds, excessive moisture and hail
  • Improved curb appeal and comfortability

Reasons to Go Green

  • Homeowners, businesses and large industries save a significant amount of money using energy-efficient products every year.
  • Heating and cooling systems, appliances and lighting products that use less energy release fewer greenhouse gases into the environment.
  • Energy-efficient products like windows and doors help to improve the comfort of homes and commercial buildings during extreme weather conditions.
  • Window World of Central Valley offers energy-efficient products that deliver quality, comfortability and affordability so it’s easy to go green.

Climate Requirements

Interested in Becoming ENERGY STAR® Certified?

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-Value
R-Value
Your Climate

U-Factor Requirements

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.

  • Northern: ≤ .27
  • North-Central: ≤ .30
  • South-Central: ≤ .30
  • Southern: ≤ .40

R-Value Requirements

R-Value determines how well the insulation inside your window is performing. The higher your R-value, the better insulated your window is.

  • Northern: 13 – 21
  • North-Central: 13 – 21
  • South-Central: 13 – 21
  • Southern: 13 – 21

Why You Need A High-Performing Insulated Product

Window World of Central Valley is located in ENERGY STAR’s North-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.


Glossary Of Terms

Energy Efficiency Terms You Need To Know

Low-E Glass

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

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

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 Gas

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.

Warm-Edge Spacer System

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.
