Visible transmittance is one of these important ratings which lets you know how much natural light will pass through the window. Searching for replacement windows means finding the most energy-efficient option to save money and stay comfortable in your home. While VT isn’t completely geared towards energy savings, it’s still an important component when it comes to finding the right window for the job.
Homeowners need to take into consideration different ratings of windows to get the best option as far as energy efficiency and preventing harmful rays. Visible transmittance is one of these important ratings which measures the amount of light that comes in. Let’s take a look at what visible transmittance is, how it’s rated, and its’ importance when searching for replacement windows:
What Visible Transmittance Is
Visible transmittance or VT rating is the measure of how much visible light travels through your window into your home. A window’s visible transmittance is ranked by the National Fenestration Rating Council. It only rates the amount of light passing through your window, not its’ energy efficiency, which would be a separate rating.
How Visible Transmittance is Rated
There are many factors that go into rating a window’s visible light transmittance. VT is measured as a percentage of the amount of light that passes through the window. It is not just the measurement of light through the glass, but includes things such as frames, sash and grids that can decrease visible transmission. Even the amount of panes on the window and the type of glass can affect the VT.
The Importance of Visible Transmittance
Homeowners and builders should know the importance of VT because it goes hand in hand with understanding other window energy ratings when choosing your windows. Many homeowners want the maximum amount of natural light without sacrificing efficiency, so selecting the right glass and window style becomes very important. The wrong Low-e, for example, may provide high VT ratings but also allow more heat and damaging UV rays into the home at the same time.
Likewise, seeking a window with a lower visible transmittance may be desired to tame rooms where the afternoon sun is most intense. A lower VT can be achieved in a number of ways without sacrificing window efficiency. Custom Windows always recommends windows that deliver the highest energy efficiency and can work with you to deliver the VT that is right for your home. The most common and most recommended solution is combining windows that deliver both high efficiency and high Visible Transmission because allowing more natural light into the home also means that you will not only use less energy from your air conditioning system but also from needing to use lights for fewer hours each day.

When searching for replacement window designs, you want something that complements your personal style and your home’s layout. New windows provide great benefits such as energy efficiency and cost savings, and they come in a variety of shapes and sizes.
What are some popular window redesign options?
No matter the style of your home, you have options when it comes to selecting your custom window design. Let’s take a look at some of the most popular types of windows that can bring sunlight into your homes, such as casement, awning, and picture windows:
- Casement Windows
- Awning Windows
- Picture Windows
1) Casement Windows
Casement windows have hinges on the side, allowing you to open them like a door. They’re good for energy savings and home security as they can be shut securely. Their functionality is preferred for kitchens above the sink area, giving a traditional window style that can easily open and close.
2) Awning Windows
Awning windows are hinged at the top and open from the bottom, creating an awning effect when lifted. These windows are beneficial for allowing fresh air into the home without the rain getting inside, as the awning prevents. They are typically placed high up to provide privacy while allowing light into the room.
3) Picture Windows
A picture window is made with fixed panes, making it stationary. Its purpose is to create a picture frame effect for you to enjoy the outdoor scenery from the comfort of your home. These windows make a great addition to living rooms to open up the space.

If you’re looking to replace your existing windows in your older home, you may face the common issue of your windows not meeting building code requirements such as egress requirements. Egress residential window codes are in place to allow escape from any bedroom directly outside in case of an emergency. Other building code requirements address safety issues, such as when and where tempered glass is required in the home. Choosing a well-rounded window company that knows all relevant building codes will help ensure your home and family’s safety, and avoid costly corrections if you try to sell your home with non-compliant windows.
Operable Egress Windows are also known to be Emergency Escape and Rescue Openings (EERO). An operable window or door leading directly outside must be accessible in every bedroom in the case of an emergency and must meet specific clear opening sizes as well.
Some locations in the home such as some bathroom windows, staircase windows, and near doors require tempered glass windows for safety. The most common situations where tempered glass is required in the home are:
- The window within 24 inches of a door must use tempered glass
- Any window larger than 9 square feet and less than 18 inches off the floor must use tempered glass
- Any window less than 60 inches from the floor of a bathtub or shower must use tempered glass
- Any window on a staircase landing or within 60 inches of a landing or staircase tread in any direction must use tempered glass
Egress requirements state that there must be an operable window or door in every bedroom that leads directly outside in case of emergencies. You can achieve this by installing windows and doors that meet the clear opening size requirements. The minimum dimensions to meet Egress requirements include:
- The unobstructed opening must be a minimum of 20 inches wide and 24 inches high, though one or both dimensions will need to be greater than this
- The clear opening must be a minimum of 5.7 square feet
- The window sill can be a maximum of 44 inches above the floor
Choosing the Right Windows for Your Home
The window code governing installation was designed to help homeowners find the safest, most energy-efficient windows on the market. A trained and experienced company, such as the team at Custom Windows of Texas, has these rules in mind to eliminate any guesswork so that you can focus on customizing your home.
