Today I’ll discus one other major reason that homeowners are calling us to replace their windows.

Wood rot is an issue many homeowners deal with and if not addressed soon enough, the problems can become exponential.

However, when you replace your rotted wood windows you can end up with a two fold solution. Non rot windows as well as a Lifetime Warranty.

The non rot windows you can have installed come either in PVC or vinyl. Now basically speaking, PVC and vinyl are the same type of material but you want to be sure you’re getting either paintable PVC or vinyl. A paintable PVC window will never rot yet still provides you the option to change colors later on if you’d like. With a vinyl window, you get a window that is both non rot, never needs paint and comes with a lifetime warranty.

Most window replacement specialist will not only provide you with a new non rot window sash but either cap or replace the trim wood on the outside of the window unit (ie. “brickmold” “sills” and “nosing”) so that those elements too will never rot again. Furthermore, a window good company will be sure to provide you with a full lifetime warranty to ensure that you not only have non rot windows but that additionally you will never experience sill damage or seal failure.

However, I’m going to start breaking down some common and even uncommon reasons (that we’ll learn about as we go) for turning to replacement windows for your home.

The first replacement reason that we will explore is a problem many homeowners in Atlanta face: Single Pane Windows.

A Single Pane Window Provides No Insulation

Now if you’re looking at this blog, chances are you’ve already become fed up with your single pane windows. Today, we’ll look at one major reason why you would want to get these windows out of your home.

Insulation

If there is no other reason to replace your windows, I would suggest that this in itself is enough to prompt a a change. Single pane windows provide minimal insulation for your home from the elements outside. They are great to see out of, providing maximum visibility, but one layer of glass will not cut down on the massive heat gain you experience in the summer or the great heat loss in the winter.

The Switch to Double Pane

Double pane windows on the other hand provide so much more than just another layer of glass. Here’s a breakdown of what you get when you replace the single pane energy eaters to energy saving vinyl double pane windows.

• The vinyl frame and sash components are much more thermal than what you will find on a wood or aluminum window (which is what every single pane window employs). Often times, vinyl window manufacturers will even fill their windows’ frames and sashes with an insulated foam to further reduce heat loss/gain.
• Glass thickness is much greater in double pane windows thus slowing down heat transference.
• The space between the two panes of glass in a double pane vinyl window is filled with a dense, inert, gas (usually either argon or the much denser krypton) to slow down heat as either enters or leaves your home. Don’t be fooled, even with double pane insulated vinyl windows, you will still gain or lose heat, (just as you still will in every other area of your home… heat is active!). But the point is to reduce the rate at which heat is gained and lost in your home every year and a dense gas between the panes reduces that rate by large margins.
• Low-e and spacer systems. Both of these elements are also common in a vinyl double pane window. Low-e (low emissivity) is a coating that actually goes on the glass in the windows to reflect heat back to its warmer side or its source. A spacer system, simply put, is the material that is between the two panes of glass that also reduces heat transference and heat loss because of it’s non-conductive properties. On that note, make sure you avoid spacers that are metallic, particularly aluminum. Though they do not rust,  they are one of the most conductive substances you can have in a window. “Warm-edge” spacers are used in vinyl windows and some recognizable, reliable names are Super Spacer, Intercept, Dura-Seal.

Call it playing hooky if you will but the guys at Atlanta Area Window and Door Co. took a day off and flew out to Chicago on June 12th to see the Braves play the Cubs, amongst other things.

Here’s our funfilled- and I do mean FILLED- day went.

6:02 am- Depart from Hartsfield-Jackson Aiport in Atlanta.

7:15 am (Central)- Touch down in Chicago

8:07 am-(Still Chicago time) Grabbed breakfast at Mitchell’s. One of Chicago’s oldest diners and home of the World’s Finest Coffee, free doughnut holes, huge omlettes.

9:30 am- Made our way up to the top of Sears Tower.

11:05 am- Toured downtown Chicago, went by the Chicago Board of Trade, Millenium Park to see the giant bean…

and then started making our way to the train for a looooooong ride to Wrigley.

12:00pm- Got to Wrigley Field early to get to our seats, Chicago dogs, and some photos.

1:00 pm- Game Time! First pitch for the Braves vs Cubs game.

4:35 pm- In extra innings, the Braves lose to the Cubs 3-2. A heartbreaker but still a good time at the park.

6:35 pm- Chicago Deep Dish Pizza at Giordano’s

8:00pm- back to the airport to catch our flight home.

9:05 pm- take off for Atlanta and 4 exhausted dudes fly home.

11:30pm (EST) – touch down back in Atlanta.

There’s our itenarary. We loved every minute of it but as you can see it was a long day.

The best story for this outing is that Mark ended up sitting three seats down from his cousin from Rockford, IL (which is where Mark is orignally from) at Wrigley! Talk about a coincidence!

Well, thanks for letting us fill you in on a little fun we got to have in Chicago.

For June, here’s another tip to help you keep cool without cranking on the AC so much in the summer time. And just in case you think we’re well into summertime we got until June 21st before it’s official. 

This tip isn’t some task you can start performing on a daily basis. It’s more of a idea that would really help as you decide how and what to invest in in terms of your home. 

Think, insulation. 

• Siding is insulated. Is your home properly insulated with the best material for keeping heat out?
• Attics, crawl spaces, floors. Do they have the best siding available in them? Most homes will use the “pink stuff” rolled out in these areas but is it the best? With advents in insulation such as spray on foam you could be getting better energy values from newer products. 
• Insulated windows. Are your windows equipped with thermal glass that slows down heat infiltration as much as possible? Low-e, double glazed windows, with a good spacer system, foam filling, and even the use of vinyl over wood can cut down on how much heat is coming into your home everyday. 

Yesterday I talked a little bit about why staying cool in the summer is largely due to keeping heat out of the house more than it is about pumping cooler air into the house. If you really want to stay cool in the Atlanta summer, you have to keep your home well insulated year round.

I thought I’d take just a minute to go a step further with some heat gain 101. And to understand heat gain better, it helps to understand how heat functions and how your windows can slow heat from coming into the house.

Heat is active. And it warms the areas that it is effecting by two means; Radiation and Convection.

It’s gonna get a little bit like science class in here so hold on. But in this post we’re only going to talk about…

Radiation

You don’t have to get our your yellow nuclear jump suit, Marty. Not all radiation is going to kill you. For our purposes we’re gonna stay focused on radiation in general terms. Without getting into all the very technical descriptions, the most basic definition I can give you is that it is how heat is transferred between two substances that are not in contact with one another.

With that in mind, the best way to fight off radiant heat is to reflect the heat back to its source. Once an uninsulated window is heated by radiant heat, it has a high emissivity factor. That’s why you’ll hear of windows that have “Low-E” or “low emissivity”. These windows with the “low-e” coating (a film that is actually coating the glass in a double paned glazed window) are reducing the heat transference by reflecting radiant heat back to where it came from.

So for starters, keeping your house cooler starts with windows with Low-e that will reflect heat back to its source and cut down on heat infiltration.

I was in a customer’s home today looking at their front door they need replaced. As is necessary, the customer and I were walking in and out of the door looking all that needs to be replaced. It was of course a hot June day and keeping the front door open as we looked around caused the customer’s wife to finally chime in with “Shut the door. You’re letting all the heat in!”

Just as those words came out of her mouth I thought, “She gets it!”.

You see, I grew up in Atlanta hearing “Don’t let the cool air out! Shut the door!” or “I’m not paying to air condition the whole neighborhood!”. But rarely do people seem to realize that even though an open door or window will let cool air escape, heat is coming into your home at a much quicker rate than it would if the door or window was closed. 

That’s why thermal windows and doors work to not only keep you warmer in the winter but cool in the summer. Properly insulated windows allow heat to come into your home at a much slower rate. Think about what your single paned or aluminum windows are doing to keep heat out? Nothing!

So if you’re looking to cut down on the AC costs this summer, think about whether or not your windows are helping or hurting your insulation. Keeping the heat out can really help you win that battle. 

If I walked into your home and offered you $1 million house tokens to buy it from you, the first thing you’d ask is, “how much is $1 million house tokens worth in dollars?” It’s the same with a U-Value. If I tell you my window has a U-Value of .25 that number means nothing to you until you understand what a U-Value is. 

What’s the Value of “U”?

For starters, a U-Value measures how well a window insulates heat. That is, how efficiently does it keep heat out of the home in the summer and  keep heat in the house in the winter to put it more simply. The reason a lower U-Value is better than a high one is because lower numbers mean that a particular window is allowing heat to transfer at a lower rate.

Heat is always active and will escape or enter your home regardless of how well your windows are insulated. But technology in replacement windows and efforts by manufacturers to lower the rate of heat transfer have given windows great insulation value. 

Putting  It into Perspective

You may have heard of “R-Values” before. The higher this number the better. R-Values apply to things such as fiberglass insulation (or new spray in foams and other methods of insulating a home), walls, and doors. 

For example:

Your insulated walls may have an R-Value somewhere around R 10-18.

And Your floors may be insulated well enough to achieve a R 20-25. 

Your attic space may have an R-Value up to R 39-49.

So with higher being better you can get an idea of what the actual value of these numbers are in terms of “R-Value”. 

Now back to U-Values. To understand their value think of the U-Value as the opposite of the R. Since R-Values measure how well solid materials insulate heat you can’t apply them to glass. Glass in windows is designed to see through and open and no matter how well it is insulated it will let heat out at some point. So in order to understand how well a window is insulated we have to understand how well it is slowing heat down NOT keeping it in like we would want to know with an R-Value. That’s why a U-Value is the inverse, or opposite, of a R-Values. 

So, to keep the math easy…

a window with a .25 U-Value has an insulation value equivalent to a R Value of 4. 

a window with a .10 U-Value has an insulation value equivalent to a R Value of 10. 

Now it’s not safe to assume that R Values and U Values are quite as interchangeable as I’ve just demonstrated but the purpose is to give you an idea of the value of each “U” number you get as you look at thermal double paned windows.

To sum up, lower U Value means a lower rate of heat transference. The lower the U Value the better the insulation of the window. We use U Values rather than R Values when considering windows because they’re really more accurate for judging how well a window is insulated. 

Also, keep in mind, when looking at a U Value make sure you know whether or not this number is for the whole window or just the center of glass. Center of glass numbers are always going to be better than the overall U of a window and to really get an accurate comparison you want the overall U Value. 

Check NFRC.org to look up insulation ratings on windows that are thermally certified or give us a call at Atlanta Area Window and Door Co. to find out about which thermal windows we offer. 

While it’s still early spring, there are some easy things you can do now to to help keep your home cooler, fight back against rising energy costs, and lower your AC bill.

Here’s one quick tip to help you stay cool-

Turn off the AC and turn on…

A portable fan!

While you’re hanging out in one room for a while, to watch TV, grab a cup of coffee and read a book, or work on your blog, grab a little fan and prop it up near by.

Or just turn on the ceiling fan for a little while. In either case, if you can reduce the amount of energy used by AC units, which not only consume high rates of energy but emit a lot of C02 gases.

So there’s a quick little way to cut down on using up a ton of energy this summer and stay cool. We encourage you to open your windows too but if you can’t get them open, we’ll be glad to help there too!

Even though it’s Spring and we’re getting into the warmer season soon, here’s some information that will help you know what elements in your window you need to pay attention to get thermally efficient windows.

Air Space

The first element of a warmer window is insulated air space. This also happens to be the first place that single paned windows are lacking. Since all you have in a single paned window is a piece of glass in a wood sash, there’s is no air space to slow down heat loss. In an energy efficient vinyl window, the double paned glass unit creates 7/8”-1” air space filled with inert gas (argon gas in most cases and krypton for that extra boost), that slows heat transference. Remember, when think about your windows, it’s not cold you’re gaining, as much as it is heat you’re losing (thus the cold). A window with an insulated air space greatly increases your windows ability to keep heat in the house where it belongs.

Spacer Systems

The spacer is, simply put, what goes between the two panes of glass. A good spacer does not conduct heat (it keeps heat from passing through the panes of glass) so that your house stays warm in the winter and cool in the summer. If you’re home has single paned windows there’s no spacer working to keep heat in the home and thereby allowing a ton of heat loss. If you have wood or aluminum windows that use an aluminum spacer, you’re losing heat through the conductivity of aluminum.

You want to have a window that has a warm edge spacer. Although swiggel (the black rubbery stuff you see in many wood windows) is a warm edge spacer (non metallic) it falls short by comparison to the latest technology found in most upper end vinyl windows. Super Spacer, Dura Seal, and even Intercept are a few offerings that help cut down on heat loss. When selecting a vinyl window that will help add warmth to your home chose one that has a spacer system you’ve looked in to and that you believe will give you the best insulation your money can buy.

Frames and Sashes

Lastly for this blog entry we’ll take a quick look at how frames and sashes can contribute to reducing heat loss in the winter. Most vinyl window frames and sashes are already better insulated than wood windows and are far better than aluminum. However, not all vinyl windows are the same. If you want that extra boost of insulation, check and see if the windows you’re looking at have a foam filling in its chambers. It’s somewhat nominal but it makes a difference to have that added filling to keep heat in the home rather than passing through a hollow sash or frame chamber.

Also, if you’re concerned about cold air seeping into the home, take a closer look at the weatherstripping that your vinyl window is equipped with. Does it give you the impression that dust, allergens, and drafts will stay out? Just one more thing to think about if you’re trying to stay warm this winter. Your windows can help you more than you know!

Believe it or not replacement windows and doors with lifetime warranties are the kind of investments that you know will last for many years to come. And it’s not just because they’re built to last.

Vinyl replacement windows that are energy efficient and use the most advanced technology of the day reduce energy usage, reduce C02 emissions, and help you save money year after year for a lifetime. When you replace a thermally inefficient single paned window, which does nothing to keep heat from transferring in and out of the house, you upgrade to a window that will ensure a reduction in heating and cooling usage.

Wouldn’t it be nice to put an investment in your home that not only helps your home become more beautiful but take a step toward going green? And wouldn’t it be nice to invest a feature on your home that not only has a lifetime warranty but comes with a lifetime warranty to cover the installation and service? Green, energy efficient, replacement windows are a step in the right direction.

There are very few investments you can make on your home in Atlanta that will last a lifetime. Not only that but there are very few investments that will increase your energy efficiency like a replacement window so that you can contribute to something positive that will help the next generation keep Atlanta going green!
