We use OKNA brand windows because of their ability to meet our our high expectations for quality. OKNA Windows takes great pride in building energy-efficient windows that add comfort and beauty to your home. Their goal is to use advanced technology available to manufacture windows and doors that exceed the highest standards.

The sophisticated technological innovations used to make their windows energy-efficient set the bar for other manufacturers and contribute to a bigger cause - protecting our environment. They surpass not only the current requirements for the government’s Energy Star certification but also the requirements set to be implemented in 2012. By conserving energy, their windows can drastically lower consumers’ heating and cooling bills each month. And with Wingler's expert installation process, we can save you even more!

Advanced Technology

Energy-efficient windows are manufactured so that heat is kept inside the home in winter and outside the home in summer. This reduces heating and cooling costs, minimizes energy consumption impacting the environment, and limits the size of the HVAC equipment required for keeping the home comfortable. In climates that mainly require cooling, windows have represented a major source of unwanted heat gain. In recent years, windows have undergone a technological revolution. It is now possible to significantly reduce solar heat gain and improve comfort while providing clear views and daylight. In warm regions, this means that high-performance windows can face into the sun if desired without great energy penalties – although shading techniques remain important.

ADVANCED GLASS COATING

ClimaGuard™ is comprised of eleven optical tuned layers, providing optimal climate control, neutral aesthetics and plenty of natural light. These coatings consist of multiple layers of metals whose combined thickness is only 1/1000th the thickness of a human hair!
INCREASED LIGHT & VIEW

Daylight and view are two fundamental attributes of a window. Unfortunately, windows are also the source of significant solar heat gain during times when it is unwanted. Traditional solutions to reducing solar heat gain, such as tinted glazing or shades, mean that the amount of light is reduced as well. ClimaGuard™ with low-solar-gain (spectrally selective) coatings can provide better solar heat gain reduction than tinted glass, with a minimal loss of visible light. This also means that views can be clearer and unobstructed.

GREATER PROTECTION FROM UV FADING

Many organic materials, such as carpet, fabrics, paper, artwork, paints, and wood may fade upon exposure to sunlight. Window selection can influence the type and intensity of transmitted radiation. The most harmful radiation in sunlight is the ultraviolet (UV) rays, which are the most energetic and thus most likely to break chemical bonds, leading to fading and degradation. Glass blocks all UV radiation below 300 nm, but transmits UV rays from 300-380 nm. Coatings on glass can reduce the UV rays transmitted by up to 80%.
IMPROVED WINTER COMFORT

Energy-efficient windows improve comfort within homes by providing a warmer interior surface during the cold winter months, preventing the living space near windows from getting uncomfortably cold. If inefficient window performance cools down the air near windows, the cold air floats to the ground. This feels like a cold draft, even though the window may be perfectly sealed.

IMPROVED SUMMER COMFORT

By reducing the need for air conditioning, energy-efficient windows that control solar heat gain also reduce the risk of possible health effects from air conditioning –for instance, the overuse of air conditioning can cause headaches or aggravate the effects of arthritis and neuritis.
LESS CONDENSATION

High-performance windows create warmer interior glass surfaces, reducing frost and condensation. Energy efficient windows with warm edge technology and insulating frames have such a warm interior surface that condensation on any interior surfaces is significantly reduced under all conditions.

Eco-Friendly

Did you know...?

35 million Americans are "True Greens"
Carbon dioxide (CO2) is the major contributor to global warming
CO2 is at its highest measured level (Antarctic ice cores) in 480,000 years
CO2 levels are expected to more than double by the end of the century
The 11 hottest years on record have occurred since 1990
The rate of temperature increase is expected to triple by 2100
Residential windows account for 10 to 25 percent of home heating and cooling energy costs
Approximately 2 lbs of CO2 are created for every kilowatt hour of energy produced from coal or natural gas

What we can do to prevent environmental degradation?

Each 0.01 U-Value improvement in your windows can save up to 400 lbs of CO2 per home/per year
Each reduction of 0.1 SHGC can save up to 200 lbs of CO2 per home/per year
Windows that last 20 years can save up to 16 tons of CO2 production in an average home
It takes three full-grown trees one year to absorb one ton of CO2 (one typical home)
The best warm edge spacer – Heatseal™–can improve total U-Values by up to 0.04 and save almost 1,600 lbs of CO2 production in energy costs per year in an average home
If every home in America had Heatseal™ warm edge spacers, we could save the environment over 58 million tons of CO2 pollution

OKNA Windows spacers insulate the edge of the glass better than solid foam or metal spacers. Better insulating spacers improve the temperature of the glass, and warmer glass makes you feel more comfortable while using less energy and producing less carbon dioxide pollution.

Also, our spacers improve the total U-Value for your windows, which reduces heat loss and saves money on energy bills.

Heatseal™ spacers can save the environment from 1,200 to 1,600 lbs of CO2 per year for a typical home.

Save Energy, Save Money, Save the Environment

Traditionally, windows are a major source of heat gain, especially when not wanted, and tinting or shading has been the way to diminish heat gain. Starmark's advanced Heat Shield coating with low solar gain provide better solar heat gain reduction than tinted glass with minimal loss of visible light.

Warm and Cold Weather Savings

OKNA's double glazed low solar gain windows in a typical 2000 sq. ft. house reduces air conditioner peak loads from 600kw to 400kw. The difference in window performance can save the homeowner about 35% in cooling cost. In warm regions this means that the window can face the sun without extensive energy penalties.

Starmark's Heatseal Spacer Guarantees your home the warmest glass and least possible condensation. In the Summer, reduced air conditioning use means a reduction in the possible health effects associated with air conditioning use.

In the winter, high performance windows create warmer interior glass surfaces, reducing frost and condensation. Windows with warm edge technology and insulating frames have such a warm interior feel that moisture in virtually eliminated, creating a comfortable environment.

ENERGY STAR WINDOWS

ENERGY STAR is a joint program of the U.S. Environmental Protection Agency (EPA) and the U.S. Department of Energy helping us all save money and protect the environment through energy efficient products and practices. Results are already adding up. Americans, with the help of the ENERGY STAR program, saved enough energy in 2007 alone to avoid greenhouse gas emissions equivalent to those from 27 million cars - all while saving $16 billion on their utility bills.

For the Home

Energy efficient choices can save families about a third on their energy bill and similar savings on greenhouse gas emissions, without sacrificing features, style, or comfort. ENERGY STAR helps you make the energy efficient choice.

When looking for new household products, look for the ENERGY STAR seal. They meet strict energy efficiency guidelines set by the EPA and US Department of Energy.
When looking to make larger improvements to your home, the EPA offers tools and resources to help you plan and undertake projects to reduce your energy bills and improve the comfort of your home.

Since the energy efficient performance of windows, doors, and skylights varies by climate, product recommendations are given four U.S. climate zones. For comparisons among ENERGY STAR® products and selecting the best product available read Buying Energy Efficient Windows or go to www.nfrc.org.

Changes in ENERGY STAR Qualifications

The Department of Energy (DOE) issued its revised 2010 criteria for the Energy Star windows, doors, and skylights program.

Among the most notable changes made in the final document are changes concerned the window criteria for the Northern zone. DOE tightened the U-factor criteria to the 0.30 level. To maximize the number of products qualifying in the zone, DOE chose not to set an SHGC maximum.DOE determined it was worthwhile to recognize the benefits of higher solar gain in some applications.

In the Southern zone SHGC is allowed up to 0.27. DOE officials note that stakeholders had expressed concern that the very low SHGC previously proposed would have reduced visible light transmission, and DOE decided it did not want to encourage production of windows providing less visible light.
