#2 – Energy Star Windows

Cooling and Heating Season Savings

Spartan Coated Energy - Efficient Glass - Engineered from the factory – provide the best LEED window choices for the least cost.

Far Beyond Ordinary Low-E Glass Spartan E glass has been the standard for energy-efficient glass. Spartan abilities to custom build windows into the building envelope designs, saves our customers 70% of their window money.

Our supply side purchase of plate glass, with state-of-the-art coatings, and also thickness for Storm areas and high security glass applications, are unmatched by any home and Smartbuildings builder from a supply side economics factor.

Spartan high transmission coatings are virtually clear, blocking the heat and reducing solar gain, while optimizing light transmission. In fact, supplied coatings actually outperform the tinted glass often used in warm climates. In addition, because our coated glass transmits more natural light and reduces solar gain, you may be able to reduce both lighting and air-conditioning electrical loads.

E Glass Aesthetics

Aesthetics of glass products – such as color, transmittance, reflectivity, etc. – are very subjective. Spartan glass is virtually non-reflective and its transmitted and exterior appearance covers a range of neutral earth tones. Viewing angle, sky conditions (blue sky vs. overcast), colors of objects being reflected, colors of materials behind the glass (e.g., blinds, draperies) and viewing distance away from the glass will have a dramatic impact on the perceived glass aesthetics. Using clear glass as a basis, the depiction to the right shows the transmitted appearance and the exterior appearance of SIP Building Envelope and custom built high quality windows.

Smart Windows

Smart Windows (SW) clean easier and stay cleaner longer. Their coated glass harnesses the sun’s UV rays to loosen dirt so water can rinse it away, leaving windows virtually spotless. Windows clean easier and stay cleaner longer. Because SW coated glass is available with any of our SW coatings, you get all of the SW coating performance benefits.

The science of SW coated glass

A variety of different technologies go into manufacturing SW coated glass. But the fundamental technology – the one that helps windows stay clean longer – is the super-thin coating we apply. Using our patented double sputtering process, we apply an invisible, durable, and permanent coating of silicon dioxide and titanium dioxide to the bottom surface and in the same pass apply the Loå layer to the top surface.The titanium dioxide layer of SW-coated glass reacts chemically with the sun’s UV rays. It causes organic materials on the glass to decompose. It works even on cloudy days. SW coated glass is also extra smooth thanks to a thin layer of silicon dioxide, making the glass hydrophilic much smoother than ordinary hydrophobic glass, allowing water to disperse evenly or “sheet off” evaporate quickly, significantly reducing water spotting. The sun and rain finish the job. When it rains, the decomposed dirt caused by the titanium dioxide reaction rinses away, leaving the glass almost spotless. Builders and homeowners spend less time washing windows—clear advantages over competitive products. SW coated glass allows more visible light transmittance than any comparable competitive product and is also less reflective.


Energy-efficient window technologies and design for maximum service life of the installation play an essential part in ensuring the sustainability of windows.

The best strategy for durability of windows is to employ good design practices to ensure the maximum service life of the installation.

Energy efficiency can be maximized by using low-E coatings, low-conductance frames and other technologies that improve the thermal efficiency of the window system. Windows built by window manufacturers (as opposed to site-built windows) can be designated as qualifying for the ENERGY STAR®, a government-backed program aimed to protect the environment by promoting energy efficiency.

Spartan supplies high performing windows and doors that conserve energy, increase thermal performance, and reduce noise. By balancing superb energy efficiency, affordability, and versatility, Spartan offers sustainable buildings and with that supplies many window choices, for any type of home and commercial project in the U.S.

The source of nearly 48% of the world’s greenhouse gas emissions are from buildings; windows and doors are key to dramatically increasing the energy efficiency of buildings and decreasing wasted energy. Spartan is committed to providing innovative solutions for SIP Building envelopes, and offer customers a innovative way to deliver new E Glass to their building choices. SIP buildings can be designed to buy the best widow glass and install into SIP Walls easily and custom made form the factory.

Through our customizable solutions it is now possible to balance costs, long-term performance, and secure savings on the ever- rising cost of energy. Spartan windows conserve energy, increase thermal performance, reduce noise, and are diversely stylish.

Impact Windows

Impact Window Solutions are a different type of window manufacturer and installer available to Southern homeowners. We proudly offer durable products that are built to resist the impact of flying debris which can even eliminate the need for adding additional protection to your home during the stress of pre-hurricane preparations. Also known as hurricane rated windows or impact resistant windows, these products are built to resist the impact of flying debris as a result of hurricane force winds. With the correct approval for their specific zone, a homeowner will not be required to provide additional window or door coverings. This eliminates the need to put up coverings or scramble for plywood during the stress of pre-hurricane preparations. In addition, with our impact windows that we custom manufacture ourselves at our state-of-the-art manufacturing facility, we offer impressive products that will instantly enhance your home. In fact, windows can:

  • Extend the life of your HVAC system
  • Add value to your home
  • Increase the security of your residence against forced-entry attempts
  • Boost the curb appeal of your residence

Impact Resistant Equals Intruder Resistant

The additional benefits of impact windows include intruder protection. A would be intruder would have to bring special equipment and work very hard to gain access through the impact resistant windows and doors, and would likely move on to a home with easier access.

Noise Reduction

An unexpected benefit from hurricane resistant windows is the reduction of outdoor sound transmittance. While the windows are not soundproof, you can turn down the volume on outside noise for a quieter inside of your home.

Solar Control and Passive Low‑E Glasses

Glass is one of the most popular and versatile building materials used today, and it provides a dramatic aesthetic. But the beauty of glass is pointless if the people inside the building are uncomfortable or if energy inefficiency makes the building too expensive to operate.

Low-emissivity (low-e) glass coatings were developed to minimize the amount of ultraviolet and infrared light that can pass through glass without compromising the amount of visible light that is transmitted. A microscopically thin transparent coating allows low-e glass to reflect exterior heat in warm temperatures and hold in heat during cold temperatures, making buildings light, bright and energy-efficient.

Cooling and Heating Season Savings

Energy Star Windows

Custom Built Windows form the Factory

Low-E coatings, gas-fills, and insulating spacers and frames can significantly reduce winter heat loss and summer heat gain. Improved Daylight and View -New glazing’s with low-solar-gain low-E coatings can reduce solar heat gain significantly with a minimal loss of visible light (compared to older tints and films).

Improved Comfort

In summer and winter occupant comfort is increased; window temperatures are more moderate and there are fewer cold drafts. Discomfort from strong summer sunlight is reduced.

Reduced Condensation

Frame and glazing materials that resist heat conduction do not become cold and this results in less condensation.

Reduced Fading Coatings on glass or plastic films within the window assembly can significantly reduce the ultraviolet (UV) and other solar radiation which causes fading of fabrics and furnishings.

Lower Mechanical Equipment Costs

Using windows that significantly reduce solar heat gain means that cooling equipment costs may be reduced.

Look for the ENERGY STAR®

The ENERGY STAR designation means the product has met specific performance criteria (www.energystar. gov). Determine your climate zone and look for the ENERGY STAR label. To distinguish between ENERGY STAR products and for recommendations for your climate zone, go to Step 2.
