Everything You Need to Know About MI™ EnergyCore Windows

Choosing the right windows is one of the most important steps you can take toward making your home more energy efficient—and saving a bundle on your energy bill. The average U.S. home loses about 30 percent of its heating and cooling energy through windows, which means you want a window that keeps heat outside your home in the hottest weather and inside your home during colder months. (Okay, cooler months. It is Phoenix, after all.)

But is there a window that can do that and still look beautiful? Yes.

The MI EnergyCore Window System delivers superior performance without compromising style and functionality. In addition to being one of the most energy-efficient window systems available, it comes in a wide variety of size options to match any décor.

What makes MI EnergyCore windows different?

Each MI EnergyCore window frame is manufactured with a patented, 100 percent recyclable AirCell™ PVC material that is co-extruded and thermally bonded. The result is a fully insulated, corner-welded frame that ensures superior energy efficiency, strength, and security. Designed to support triple-pane insulating glass, the EnergyCore frame is also reinforced with aluminum at the lock rails for maximum security.

Several air and water barriers are engineered into the EnergyCore window panel and frame interface to keep your home interior dry even during monsoon season. These barriers include multiple contact points of weatherstripping and/or compression bulbs, interlocking meeting rails, and a pocketed sill with a sloped drainage path.

What does all of this mean in terms of energy efficiency?

The strength of the window frame, combined with the built-in air and water barriers, makes the MI EnergyCore window six times more effective than fiberglass, four times more effective than rigid PVC, and three times better than wood at blocking thermal conductivity.

When we combine the MI EnergyCore frame with our high-performance, triple-pane, argon-filled TMAX glass packs, the resulting window exceeds ENERGY STAR® requirements by 30 to 50 percent and meets the requirements for the U.S. Department of Energy R-5 program for high-performance windows. (R-value indicates how well a window resists the flow of heat, and R-5 windows are considered the most highly insulating and energy-efficient windows.)

All styles of the MI EnergyCore window series, including the R-5 insulating window, have been tested to an AAMA Performance Grade 40 or above.

How do MI EnergyCore windows help homeowners save money?

In a nutshell, energy-efficient windows help reduce energy consumption. And when your heating and air-conditioning costs go down, so do your monthly utility bills. Whether you are buying a new home or thinking about replacing your existing windows, consider the MI EnergyCore Window System from XO Windows and see what a difference the right windows can make.

What Is Window Glazing? Here’s Everything You Need to Know

A window is more than a peek at the great outdoors. Every day, windows protect us from harsh weather and natural elements. They also fill our home with beautiful, natural light.

That’s not to say all windows are equal, though. In order for a window to do its job, it needs to have the right features.

Window glazing is the perfect example. Here in Phoenix, glazing is what will shield you from the desert heat. It can also be what stands in between you and an energy efficient home.


What is window glazing?

Window glazing refers to the glass in a window. Specifically, it influences the transfer of energy, so it’s certainly worth thinking about.

Energy efficient windows are especially important in the Phoenix area. In the hot summer months, air conditioning is a must. But during the winter nights, it can be cool enough to turn on the heater.

The last thing you want is heat sneaking in (or out) of the window. Something tells us your wallet would agree, too.


What are the types of window glazing?


Single Glazing

Single glazed windows are made with just one pane of glass. They don’t offer much insulation, so it’s easy for energy to move in and out. It’s the perfect setup for a heart-stopping energy bill.

If you have older single-pane windows, the glass probably has a “glazing compound.” This putty is used to hold the glass in place and keep out air. It can last for years, but eventually, it will dry out and crack.

Once upon a time, all windows were single pane. Today, they are much harder to find.

Yet, some homeowners like single-pane windows because they have a traditional appearance. If you decide to install them, make sure the frame is made of high-quality material. The windows should come with storm panels, too. This will help you save both energy and money in the long run.


Double Glazing

Double glazed windows have two glass panes with at least 12 millimeters of air in between them. This gap is sealed shut, so the air can’t escape. In turn, the air provides insulation.

The thick barrier of a double paned window also slows down energy transfer. In fact, compared to single glazing, double glazing can lower heat gain (or loss) by up to 30%.

Triple Glazing

Triple glazed windows are made with three panes of glass. Sometimes, the middle pane is a plastic film. In either case, there are two layers of air sealed within the window.

The extra pane makes a significant difference. Because the window is so thick, heat will have a hard time passing through. This makes them a smart choice for cooler climates.

There are even more options to choose from.

Window glazing isn’t just about the number of panes. Depending on your needs, you can choose from a range of high-tech glazing systems.


Low-E Window Glazing

Low-E stands for low emissivity. Low-E glass has a coating of metal oxides that reflect the sun’s energy. Depending on your climate, you can choose a coating that allows or blocks energy.

Hard-Coat Low-E is a strong, durable coating that brings in heat. Therefore, it’s ideal for cooler climates.

On the other hand, Soft-Coat Low-E is a thin coating that reflects 82% of solar heat back outside. It also only lets in 18%. This certainly beats normal clear glass windows, which release 84% of energy into the home.

As you can imagine, we’re all about Soft-Coat Low-E here in Phoenix.


Heat Mirror Glass

Heat Mirror takes it up a notch. A sheet of Low-E film is placed within layers of insulated glass, making it a stellar choice for reflecting heat. The film also blocks out 99% of UV rays.

Listen to Your Windows (Let Us Translate for You)

As pleasant springtime weather continues to roll in, and temperatures continue to rise, you may be opening and closing your windows more frequently, alternating between fresh air and air conditioning.

All that window opening and closing might be telling you something — if you’re paying attention. Here are some signs you need to listen to your windows. We’ll translate for you, so you can take action.


“Help, I’m stuck!”

Windows that are hard to open and close might be a sign of swelling wood. When the air is damp or humidity is higher, wood-frame windows can expand making it hard to open and close them without extra effort. This is a common problem with double-hung windows and changing humidity conditions.

Additionally, both wood and vinyl windows may have springs or other mechanisms that make them easier to open and close. But, sometimes these mechanisms wear out, or stop working completely, in the first five years of the window’s life. Once you replace the part, your window functions more easily again. You can also use a lubricant in window tracks to make them a bit easier to open and close when they get stuck.


“Hey! It’s kind of drafty in here.”

Do you feel a draft when you’re sitting next to a window in your home? If so, your window may be alerting you that it’s time to replace the weather stripping to keep the outside air out and the climate-controlled inside air in.

Another reason you may feel a draft is when your windows aren’t as energy-efficient as they could be. In that case, the glass itself could be making it drafty. Replacing old windows with newer, more energy-efficient ones can make a big difference in your comfort level and in your utility bills.


“Am I the only one getting wet around here?”

Your windows can be “getting wet” in a few different ways:

  • Condensation between window panes
  • Condensation along the bottom corners of window panes
  • Water in the window track

Each of these problems is telling you something different, so here’s how to interpret the different types of window leaks:

Condensation between the panes of glass means your double- or triple-pane windows are no longer doing their job of keeping outside air outside. When moisture from outside stays trapped between the panes it most likely means you need to replace the window.

On the other hand, condensation that forms along the bottom corners of window pane are a sign that your home has too much moisture. This is common in bathrooms after a hot shower, too. Try running a dehumidifier or fans to lower the moisture levels inside your house. Otherwise, you may end up with a mold and mildew build-up problem.

After it rains, if you notice water in the track or on the sill, it could be a sign that your window doesn’t close tightly enough. Check the window lock. Is it broken or not functioning properly? That can be an easy fix.

If you notice any of these issues, your window may be trying to get your attention. If you listen, it could help you save money in the long run on costly repairs or as a result of high utility bills.


The experts at XO Windows understand when windows are trying to tell you something, and we’re here to answer all your questions. We can help you keep your windows and your home free from these common concerns. Just give us a call, send us an email, or fill out a request for a free estimate.


Considering Replacement Windows this Spring? Common FAQs to Help You Choose


Springtime is a great time for cleaning out the old to make room for the new.

The rebirth of spring makes everything feel fresh again outside, so maybe that’s why we’re so motivated to revitalize the inside of our homes as well.

As you declutter and spruce up your home, you may realize you need to replace some windows to completely refresh your surroundings. Here are some frequently asked questions (and answers) to help you get the best replacement windows for your house.


FAQ 1: Which type of windows should I get?

Answer: When it’s time to replace your windows, it’s also a great opportunity to select something new.

Perhaps you’ve always wanted horizontal sliding windows, or a specialty-shaped window to add more style to your home. Or, maybe you’re looking for windows that are much more energy-efficient than your old ones — or both.

Whatever the case may be, choosing a professional window company that offers a variety of styles and options means you’ll get high-quality windows and expert assistance with selection and installation.


FAQ 2: Do I need to replace the entire window frame or just the glass?

Answer:  That depends.

If your window frames are still in good shape, but you have cracked or broken glass, you don’t necessarily have to replace the entire window.

Broken windows are hazardous, especially for children and pets, and they could also be costing you extra money since they’re no longer energy-efficient.

Consider how much it’s going to cost just to replace the glass, and how old your windows are, and it may make more sense to replace the entire window.


FAQ 3: What materials are best for my climate and location: vinyl, aluminum, wood, or fiberglass?

Answer: In hot, dry climates like Phoenix and the surrounding areas, energy-efficient windows that keep cool air in and hot air out are best. MI EnergyCore™ Windows are one of the options for high-performance, energy-efficient windows.

And, they come in a variety of designs to match any décor, so you don’t have to sacrifice style for performance. MI EnergyCore frames are made of a patented AirCell™ PVC technology and insulating glass.

Vinyl windows offer affordability, durability, and low-maintenance along with energy efficiency.

Fiberglass windows are also excellent in efficiency and durability since the material expands and contracts very little, preventing air leaks around the frame.

Aluminum frames are long-lasting and durable, and offer a more industrial appearance. Compare the benefits of vinyl and aluminum windows here.

Wood is an elegant choice for decorative windows, but requires more maintenance than the other materials. As long as you protect and maintain the beauty and energy efficiency of wood frames, your new wood windows add style and value to your home.

Springtime Window Safety: What You Need to Know

Springtime is just around the corner, and for many of us, our favorite time of year in the desert. Opening your windows to let fresh air inside is a symbol of the renewal of spring when plants begin to blossom and nature comes to life.

While open windows let the scents and sounds of springtime into your home, it’s important to be aware of the risks of open windows, too: children and pets falling out and intruders getting in.

According to statistics, more than 5,000 children under the age of 11 fall out of windows each year; but with these safety tips in mind, you can prevent children and pets from falls and injuries. Plus, you’ll be doing your part to keep intruders out.


Window Safety Tips

Let breezes in, keep kids and pets safe.

If you have double-hung windows, open them from the top. It makes it much harder for kids and pets to slip through an open, less-accessible space if your windows are open from the top. Additionally, an open window that’s too high to reach without a ladder can prevent potential intruders from breaking in.

Don’t rely on screens for protection.

If a child or pet leans or pushes on a screen, the screen can fall out and so can they. Your screens are a great deterrent for bugs, but not much else. Screens can easily fall out of place from the inside, or be removed from the outside. Don’t rely on them as a safety feature.

Move furniture away from windows.

Even when you open a window from the top, be sure there isn’t a couch or bed, or anything tempting for toddlers to climb on to access a window.

Assess your windows from the outside.

Can you jiggle or push them open? Are the locks secure? If not, or if windows are in a location that make them easy-access points into your home, consider adding safety precautions like removable window guards. These aluminum or metal grates are designed to prevent children and pets from falling out, but they’re also a great visual deterrent for would-be intruders who won’t waste the effort removing them to get inside.


Repair or replace broken windows.

We don’t just mean a broken window pane. If your window locks don’t function properly and lock tight when you shut them, children may be able to push them open from the bottom and risk falling out. It may be time to consider replacement windows for better security as well as better energy efficiency.

With these safety tips in mind, you can enjoy the fresh springtime air, without the worry of potential injuries or intruders.

Home for the Holidays? Simple Tips for Safe Window Decorating

Did you know tens of thousands of injuries and ER visits occur every year as a result of holiday decorating “mishaps”? That’s about 250 injuries each day during November and December, according to the U.S. Consumer Product Safety Commission.

Here are a few simple tips for safe window decorating during the holiday season.


Batteries are a bright idea.


A candle in every window is a timeless way to celebrate the spirit of the season (not to mention a great way show off your beautiful professionally installed windows). If your old plug-in candles have been around the block a time or time two, consider replacing them with newer versions that use batteries instead of electrical cords for a safer alternative.


Be smart about gel clings.

Window Decorations

Little ones especially love sticking those brightly colored candy canes, ornaments and snowflakes on the windows—and who can blame them? They’re so appealing they almost look like candy… and now you see the problem.

To avoid a choking hazard, be sure to place window clings high enough on your windows or glass doors so little hands (and paws) can’t reach them and be tempted to eat them.


Keep window ornaments out of reach.


Delicately hung ornaments are a simple, elegant way to bring a touch of holiday cheer to your windows. Try to choose sturdier ornaments (to prevent shattering in case they fall) and remember to keep them high enough out of reach of little hands.


Walking in a window wonderland


These simple tips will help you ensure a warm and safe welcome for family and guests during the holiday season—but why should your decorating end there?

Specialty shaped windows and picture windows from XO Windows create a stunning display you can enjoy all year long. Call or email us to find out more, and have a safe and happy holiday season!

It’s That Time of Year…for Window Inspiration

During the hustle and bustle of the holiday season, these timeless lyrics from a traditional yuletide song come to mind:

Frosted window panes,

Candles gleaming inside…

For many, this phrase evokes a romantic image of a warm, cozy home, but for those of us in the window business, “frosted window panes” are a cause for concern! If you have frost on your windows, it may be time to replace them with ones that are better insulated.

In the spirit of the season, we’ve put together some ideas to inspire you. It’s our little gift to you during the holidays: window inspiration that will not only help keep your home well insulated, but beautiful designs that are, dare we say, worthy of mention in a holiday song.

The Sky’s the Limit

Aluminum Clad Wood Windows

When you’re deciding on windows for a newly constructed home or replacing older windows in your current home, which windows do you choose? Do you know where to begin?

Benefits of Sliding Windows


Sliding Glass Windows: Beauty, Benefits, and a Better View

If you’re tired of trying to loosen stuck window frames or asking the strongest person in the house to open the windows for you, sliding windows could be the solution. Sliding windows are an aesthetically attractive window solution that combines wider, more natural views of the outdoors with effortless function.


How do sliding glass windows work?

Sliding glass windows are like sliding glass doors: they open horizontally instead of vertically. Typically, one side of the window remains stationary, while the other pane slides on rollers. Plus, there are limitless options of colors, styles, materials, and finishes to match your home or business.


Sliding windows are easy to open.

Enjoying fresh air in the springtime or letting cool breezes flow through your home are just two of the benefits of easy-opening windows. Well-maintained sliding windows open and close with just a gentle push and are ideal for hard-to-reach spaces.


Sliding windows are low-maintenance.

Generally speaking, sliding windows are a lower-maintenance window option than many traditional windows because they have fewer moving parts. That means easier opening and closing, and less chance they’ll become difficult to operate as the windows age.

Sliding glass windows function smoothly for many years. Some window styles can even be tilted to make cleaning a breeze, both inside and out. Other styles allow you to pop out the glass pane completely.


Siding windows are energy efficient.

Yet another benefit of sliding windows? Their energy efficiency. These windows close tightly to keep climate-controlled air in the inside and minimize drafts from the outside. At XO Windows, we offer the available option of the i89 Surface 4 Low-E glass package for optimal insulation against cold air flow.


With the i89 Surface 4 Low-E glass package, your home or business can be cooler in the summer and warmer in the winter. This high-performance window glass option reflects heat back into the room and improves the transmittance of daylight. The window is smooth, scratch-resistant, and easy to clean, too.


A room with a (better) view.

Wherever you choose to put one of XO Windows’ sliding glass windows, you’ll enjoy the benefits of a wider view to the outdoors. Your eyes naturally see further side-to-side than up and down, so a horizontally oriented window offers a wider, more picturesque view of what’s outside your home or office window. Sliding windows also allow more natural light to enter into your surroundings.


Whether you’re replacing older windows or choosing windows for new construction, XO Windows’ selection of sliding glass windows offers attractive, easy-to-use, energy-efficient options for a variety of decor and designs. Get in touch to find out more.


Seven Reasons You Need Vinyl Windows


Vinyl Windows

Whether you’re building a new home, remodeling or merely need to replace windows that are showing serious wear and no longer performing, we’ve got some compelling reasons you should be considering vinyl.

1. Long-Term Efficiency and Savings

We gave this one the top spot because, where most homeowners are concerned, it’s vinyl’s most important feature. Since vinyl doesn’t expand or contract with fluctuating temperatures, it seals in cool or warm air better than any other material, which cuts down on waste and saves you serious money on heating and cooling bills.


2. Short-Term Savings

Even though vinyl is a high-quality and practical choice, it’s still among the cheapest options when shopping for windows.


3. Low-Maintenance

Not only is vinyl warp and crack resistant, but chips and scratches are barely visible since vinyl’s color goes beyond the surface. Also, cleaning is a snap, since all you need is some cleaning spray or a little soap and water to make it look good as new.


4. Choice of Colors

Forget having to go the paint store; vinyl comes in almost any color, so you can choose the best color to complement your home without having to go through the hassle of painting.


5. Choice of Styles

Vinyl windows can be purchased in any size or shape and can even be customized for more unusual design ideas.


6. Curb Appeal

Since vinyl windows rarely show signs of wear, they look newly installed for years, with minimal effort from the homeowner.


7. Environmentally Sound

When you choose vinyl, you’re not only cutting down on energy waste and heating/cooling emissions, but you’re also using a material that can be easily recycled once it’s no longer in use.


At XO Windows, Arizona’s largest window distributor, we carry an array of beautiful, durable vinyl window options like:


XO Windows offers several glass choices, as well, including energy efficient, textured, tinted, protective, solar control, etc.


We offer free estimates and consultations, during which our experts can help you choose the right type of window for any project. Our installation team is the best in the area and are able to work seamlessly alongside contractors and tradespeople to get the job done on schedule and right the first time.

If you have questions about vinyl windows, glass types, cost, etc., feel free to reach out any time.
