Energy Star Products in in Phoenix & Mesa, AZ


ENERGY STAR is a government-backed symbol for energy efficiency. Since 1992, ENERGY STAR and its partners have helped save businesses and families an estimated 430 billion dollars while also reducing emissions. Consumers rely on ENERGY STAR labels to make well-informed decisions when it comes to saving energy and making the world a greener place to live.

A window or a door cannot be associated with ENERGY STAR prior to obtaining a certification from National Fenestration Rating Council (NFRC), which is a Certification Body recognized by EPA for residential windows, doors, and skylights. As part of this certification process, the windows and doors must be tested in a laboratory recognized by EPA.

What does the

An ENERGY STAR label will tell you if a product is energy efficient; however, the NFRC label allows you to compare between energy efficient products by breaking down a product’s energy performance in detail.

Our Signature “Krasiva Panoramic & Visions” standard glass reflects 99% of UV.

According to the NFRC, each year, the average American household spends $1,500-$2,500 on energy bills and 45% of that cost is for heating and cooling (also check the DOE: Reporting an estimated 50% of energy in a home is lost through the windows).

There are multiple categories which help you compare between energy efficient windows and doors:

The lower the number, the better the windows and doors will be at keeping the air inside your home at a reasonable temperature. (E.g. – if it is hot outside, a lower U-Factor number will help keep your house cool.)

Air Leakage
Have you ever felt a draft of air come through an old single-pane window? This rating measures how much air will ‘flow through’ the products. A lower number is better, it means there is less air flow through the product itself.

Visible Transmittance
This rating determines how much natural light the windows and doors will allow to pass through the glass, which can potentially save money on artificial lighting. For this rating, the higher the numbers are better – a higher number here will allow more natural light in through the glass than a lower number would.

Solar Heat Gain Coefficient
A lower number here will help the windows and doors resist unwanted heat gain which means you’ll spend less on cooling down the inside of your home.

So Now
What Are the Benefits?

The NFRC website displays an ENERGY STAR chart which gives you an idea of how much energy efficient windows can save you.

There’s a plethora of benefits which comes from upgrading the windows and doors in a home in addition to energy savings.

Some high performing windows and doors will allow high levels of visible light to pass through the glass while still maintaining great efficiency numbers. That means more daylight can enter your house while still keeping the inside at a comfortable temperature. This will allow you to keep the artificial lighting in your house turned off, which in turn also decreases your energy consumption.

New windows also help keep your fabrics looking new. UV radiation can cause fabrics to fade by 40-60%. The radiation passes through the glass whether it’s cloudy or sunny outside; however, new high performing windows can reflect up to 74% of the damage caused by harmful UV rays.

The structure of a window directly impacts how energy efficient it can be.
