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.

An Inside Look

SolarZone™ Insulated Glass Package

How does Low-E glass (LG) work?

Low energy windows in the winter
Low-E glass filters long-wave radiation from the sun. This reduces solar heat gain from the sun in the summer, keeping your home cooler.
Low energy windows in the summer
Low-E glass takes on a new duty in winter months. It lets warm solar rays into your home while blocking the heat in your home from getting out.

How does the Intercept™ spacer system work?

  • Its one-piece metal alloy, U-channel design creates a thermal barrier to prevent conducted heat loss.
  • The sealed one-piece design improves its ability to retain insulating gas when compared to many conventional designs.

How do Intercept™ spacers add to room comfort?

  • They keep the edges of the window glass warmer so your home maintains a consistent temperature during the winter.
    The temperature difference between the edge of an insulating glass unit with an ordinary spacer and one with an Intercept™ spacer system can be substantial.

How do Intercept™ spacers help windows to last longer?

  • LG units expand and contract as temperatures fluctuate.
  • In typical insulating glass units, the sealant holding the unit together bears the brunt of this flexing and can cause seal failure and insulating gas loss and leaks over time.
  • In an Intercept™ LG unit, the spacer flexes instead of the sealant so it resists spacer movement and premature sealant failure, making this an exceptional investment.

What difference does Low-E glass make?

When comparing the two thermography images, the difference is obvious. The window on the left is a clear insulated glass unit. The heat transmittance, indicated by the green, yellow and orange colors from the heat scale, is far inferior to that of the window containing the Solarban® 60 Low-E insulated glass unit (right).

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. Window World offers many ENERGY STAR® qualified glass packages. 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 performs. 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 Pensacola is located in ENERGY STAR’s Southern Climate category. To maintain certification here, our windows and doors must maintain a U-Value of ≤ .40 and an R-Factor from 13 to 21.


Glossary Of Terms

Energy Efficiency Terms You Need To Know

Low-E Glass

Low-E glass is a type of glass that has been treated with a microscopic, metallic coating designed to filter certain types of light into your home. The glass blocks heat gain from the sun’s reflected rays in warmer months and allows warmth from the sun’s shorter rays to flow into your home during cooler seasons.

Warm-Edge Spacer System

Our Intercept™ warm-edge spacer system is a new-age technology used to extend 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 of its kind.

Argon Gas

Argon is a colorless, odorless and nonreactive insulating property with extremely high density and extremely low thermal conductivity, making it an ideal agent for year-round comfort.
