Window Features

Neopor is a graphite polystyrene rigid foam insulation that gives maximum efficiency and sustainability in building products. It is comprised of many small pockets of air within a polymer matrix containing graphite. The graphite reflects radiant heat energy like a mirror, increasing the material’s resistance to the flow of heat, or R-value. Most polymer-based foams exhibit a greater ability to slow the movement of heat as the temperature decreases; however, Neopor is unique because it increases R-Value as the temperature
outside drops.

The vinyl profiles used in an EndureTM window are designed with premium wall cavities providing the highest levels of efficiency. This strong and rigid vinyl extrusion keeps you comfortable in your home without the need for insulation.

To provide further comfort, ProVia® uses Neopor insulation in certain cavities for even greater performance. Therefore, you can rest assured both the window frame and sash, along with the Neopor insulation are effectively regulating the temperature inside your home.


Weatherstripping is a very important part of preventing air from coming into your home. ProVia’s windows have weatherstripping on the frame and sash, ensuring you get a good seal at the important locations where air could pass through.

Bulb Seal

Bulb seals are seamless closed-cell compression seals that prevent water from penetrating the foam cell structure. Its extruded skin provides a unique UV resistant barrier with design features that enhance the weatherstrip’s sealing performance.


Seal woven and extruded pile weatherstripping with fin provides a very effective barrier against air, water, dust and noise, sealing against even and uneven surfaces with resistance to abrasion.


BetterVue® Fiberglass
Your EndureTM window will come standard with an extruded aluminum frame with BetterVue fiberglass mesh, which can be easily removed for regular cleaning and maintenance.
BetterVue screen mesh is very durable and flame retardant, providing an enhanced view, increased insect protection and improved airflow.
Now featuring Phifer’s® Water Shed TechnologyTM, which preserves optical clarity by shedding water and resisting dirt and grime.
The Water Shed Technology features a hydrophobic coating that will not wash off, which allows the screen to shed water and debris from a rainstorm or garden hose. This means your screen virtually eliminates window panning, a process by which the water fills the open squares in the screen.

Nearly indestructible. Barely visible.
Available with BetterVue or Heavy Duty Fiberglass Mesh.
PVC coated spring steel frame with no attachment hardware.
Simply hold the screen in your hands, bend the sides in, and fit
FlexScreen into your screen pocket.
No more bent aluminum frames, scratched paint and broken hardware.
FlexScreen easily hides in the window screen pocket, drastically
improving sight lines.

Our philosophy is to provide homeowners across America with more value than any other company in the marketplace. We accomplish this by leveraging our national footprint to offer exceptional prices on the most efficient windows available. It would be our sincere pleasure to demonstrate the remarkable qualities of our Triple Pane upgrade option.

Q. What is Triple Pane?
A. Most windows today come with two panes of glass, often called “Dual Pane” or “thermopane.” These windows provide excellent insulation properties for your home, often qualifying for Energy Star —standards. Triple Pane glass uses THREE pieces of glass instead of two!

Q. What are the benefits of Triple Pane Glass?
A. There are quite a few! By inserting a third pane, the “engine” of your windows is supercharged. This additional barrier provides lower U-Factors, reduces sound transmission, and increases a window’s resistance to interior condensation.

Q. Is Triple Pane Glass expensive?
A. From most companies, YES. From Window Depot USA, NO. Our national size and buying power allows us to offer Triple Pane glass for less than most companies charge for Dual Pane.


Looking for the ENERGY STAR label is a simple way to save you money and protect the environment. Now EPA introduces ENERGY STAR Most Efficient 2017, a new distinction that recognizes products that deliver cutting edge energy efficiency along with the latest in technological innovation. It is an award that truly represents the best of ENERGY STAR.


Triple Pain Windows

For many years, windows were made with a single pane of glass. And while this pane of glass provided shelter from the elements and a view to the outside world, it provided modest insulation for your home, at best.

Scientists and engineers knew that in order for a window to provide true energy-saving insulation power (and remain clear and beautiful), it must combat all the sources of energy loss through the glass. This is where the Insulated Glass Unit comes in. Insulated Glass Units secure two or three panes of glass together into an airtight unit, utilizing SPACERS to hold the panes apart and seal them together at the same time.
The other elements of an IG unit include Low-E coatings on the surfaces of the glass (to block certain IR and UV rays), and various INERT GASES (which are better insulators than air) used to fill the inside of the unit.

Collectively, this combination of glass panes, Low-E coatings, gas fills and spacers make up the Insulated Glass Unit. An IG is also sometimes referred to as a “glass package”.

By combining the right technologies into several glass packages, Window Depot USA was able to create our “Energy Bundles”. These bundles allow you to choose a glass package that fits your energy needs and budget.


Solar Heat Gain, Visible Light and U-Value – these are all important factors that should be weighed when choosing windows for your home. They all interact with one another to create a harmonious product that is right for you.

For instance, Silver Plus package combines high visible light percentages with a moderate insulating value. It is a great balance of performance and value. However, for those customers seeking maximum insulating power, our Platinum package offers one of the highest insulating factors available.

The key to choosing the right glass package for your home is to find the right combination of performance values to suit your needs. Look to your Window Depot dealer to help you make these decisions. Our philosophy is that one size doesn’t necessarily fit all, which is why we created the Window Depot family of glass.

Solar Heat Gain Co-efficient
The fraction of solar radiation admitted through a window including what is absorbed and subsequently released inward. The lower a window’s SHGC, the less solar heat it transmits and the greater its shading ability. Different climates require different SHGC values for maximum efficiency.

A measure of the rate of non-solar heat loss or gain through a material or assembly. Tests are usually performed under conditions which simulate 0 ̊ outside and 70 ̊ inside with a 15 MPH wind. The lower a U-Value, the greater a window’s resistance to heat flow, and thus the better its insulating value.

Visible Light (VL):
This is the fraction of the visible spectrum of light weighted by the sensitivity of your eyes that is transmitted through the window. It represents the amount of daylight that the window lets in and can be referred to as “Visible Transmittance”.

Low-E coating is a microscopically thin, virtually invisible, metallic layer deposited on the glass surface primarily to reduce the U-Value by suppressing radiant heat flow. Low-E coating is virtually transparent to the solar spectrum (visible light and short-wave infrared radiation) and reflective of long- wave infrared radiation.

Argon & Krypton are odorless, colorless, non-toxic inert gasses that can be used instead of air between panes of glass to increase insulation and energy efficiency. Argon is an excellent insulator, a good value and more readily available. Krypton is a denser gas and therefore a better insulator.


ENERGY STAR is a joint program of the U.S. Environmental Protection Agency and the U.S. Department of Energy, helping us all save money and protect the environment through energy efficient products and practices.
Energy Star rates the energy efficiency of products like refrigerators, dishwashers, HVAC units and Windows.

What is NFRC?
NFRC is an agency that establishes thermal performance testing criteria. Through third party agencies, the NFRC allows window & door companies to certify to strict Energy Star compliance, and label their products for an independent, “apples to apples” energy savings comparison.

Every window is labeled with the NFRC energy- rating label. Look for this label on your window for exact energy performance ratings, which are based on the overall performance of the window.
You should pick the windows that make the most sense for your climate. While some windows are better at keeping you warm, others excel at keeping you cool. Performance criteria are based on these climate zones and ratings certified by the National Fenestration Rating Council (NFRC).

At Window Depot USA…we’re proud to be known as ‘America’s Triple Pane Company’. That’s because we specialize in delivering state-of-the-art window technology at incredibly affordable prices.

The style of grids you choose can make a big impact on your home’s appearance. Grids look great on the front side of a house or in accent windows throughout the home. You can choose from internal or external grids and several grid patterns including variations of Colonial, Cottage, and Prairie styles.

External Grids
Simulated Divided Lites (SDL) Grids are applied to the glass on both the interior and exterior of the window. If you decide to get painted windows, choosing SDL’s as your grid choice allows the SDL’s to be painted to match your exterior window color.

Internal Grid Types
If you want grids, but prefer not to clean around them, opt for internal grids so you get the same look and feel, without the hassle.

Privacy Options
Choose from five different types of glass if you need light to filter in, yet want to maintain privacy. These glass styles look great in rooms where privacy is important. Regardless of where it is used, privacy glass reduces the likelihood of needing extra window coverings.

Tint Options
Our tinted glass can help reduce UV transmittance, solar heat gain and glare. Tinted glass options can give a room a whole new look, providing its own unique set of benefits. Be sure to choose the right one for your home.


If cleaning dusty blinds makes you cringe, be sure to add internal blinds to your windows. These blinds are made with sturdy aluminum and are custom-fit to the exact dimensions of each window.

Internal blinds work great in all bedrooms and bathrooms in the house. Blinds can be lifted up to allow maximum light in or they can be tilted to keep some light out and to maintain privacy.
