My windows have been Infiltrated!
In the Window Industry, “Infiltration” refers to Drafty Windows–how much air goes through a closed window measured in cubic feet, and a good rating is considered to be below “.30”.
Drafty, non-sealing windows account for millions of dollars of wasted heating and cooling cost. In fact, the number one source of wasted money in a home.
Are drafty windows flushing good money down the toilet in your home?
I mean, what good is insulation and a high efficiency SEER rating Air Conditioning system if you’re expensive treated air is just being washed across the neighbor’s yard?
How can you tell?
Sometimes, you can feel the draft–especially on a cold day. (Little secret? Every temperature of air goes through a drafty money costing window– you just FEEL the cold).
The house I grew up in in New Braunfels had old steel casement windows on two and a half walls. Boy, during a windy cold front, it was cold in there!!!
Or, when you open JUST ONE window, and you immediately feel a burst of a cross-wind of air. If all the other windows were sealed, opening one window would NOT cause wind to flow!
Can I tell you a personal story?
I lived in Ohio for 6 years. Initially, it was not going to be that long, so I rented an apartment in downtown Massillon, just off the main drag above a hair salon. It was a great deal (I thought), 1400 sq ft for $550 a month.
Well, I learned about cold.
The day after Thanksgiving, it snowed 8 inches. Not pretty “snow globe” snow, but snow that seemed to come from a sand blaster!
That wind literally “whistled” through those old windows (and they even had storm windows added to the outside). I don’t think I could keep a candle lit.
Needless to say, I was miserable. That year, it stayed cold, and more snow kept coming but that original Thanksgiving 8 inches (the Bow Hunters loved it) was still there in April.
And, I had, and still have, two very talkative parrots as pets. Tropical heat birds that looked at me like I was crazy.
I had to seal those windows.
In Ohio, that means you buy a 3M kit which has double sided tape that you stick around the outline of the window opening on the inside, peel the tape, and attach a sheet of supplied thin clear plastic to the tape to stop the air flow.
And then, you take a hair dryer which heat shrinks the plastic to where it’s tight and wrinkle free, and Voila!! The air is stopped.
Except, and please try to imagine this, those early winter storms are very windy and the snow goes sideways. The wind pressure on those 9 windows was incredible and, I can still see this, that plastic would be bowed out like a huge piece of bubble wrap.
And, when the wind changed direction? That plastic would go from convex to concave in an instant… and SNAP… SNAP … SNAP …. all nine windows in rapid sequence would “POP” as the wind changed.
The parrots hated that. I got all the various drafts sealed eventually, and turned out to be the warmest coziest place (and cheap to heat).
So, yes, all homes have windows. Some have double pane or even storm windows ( that Ohio apartment did), but if they don’t have a good “Infiltration Rating”, or just weren’t installed right, or, have weakened with age…
Get some good tight sealing windows and your wallet, you loved ones, and even your pets will thank you.
Billy Idol is a Chicken Fried Steak
Or, What do all those Replacement Window Stats Mean?
Stats, Technical Jargon, TLA’s (Three Letter Acronyms…LOL), they can be a great help in evaluating and comparing products.
But, intimidating, too.
Especially when it is an expensive one time purchase and none of the numbers mean ANYTHING to you.
In college at Texas A&M, I worked weekends and nights as a cook in a busy Fajita joint called Padre Cafe.
The kitchen was hot and smoky from grilling meat and caramelized onions and, of course, my first day was on Game Day!!! 6 hours and over 1000 meals to crank through.
The lead cook, who looked like a wiry Charles Manson, was pacing the blistering hot line like a caged tiger with a 10 inch very sharp knife held in a greasy death grip waiting for the rush to start.
The tape player railed at top volume Heavy Metal music or the Ramones.
As the new guy, I was put on fryer.
“Manson-Metal-Dude” looks over at me, while he’s flipping the tape in the player, and says, “Billy Idol’s a Chicken Fried Steak”, sneers, jams his knife up and down in an “Air Guitar” motion and pushes “Play” so I’m left pondering what the hell that means.
I figure it out.
Every time he pulled a new ticket, if he looked in my direction, and made that same knife wielding Billy Idol Sneering Air Guitar motion…. I was supposed to make a Chicken Fried Steak.
Billy Idol Impersonation = Make Chicken Fried Steak!!!
Communication at its best. We rocked that night, and I smelled like beef fajitas that entire semester ( I quickly got moved to grill).
So, let’s see if we can figure out those mysterious Replacement Window Stats like “U-Factor”, “SHGC”’s, etc. mean.
First, U-Factor. You may be more familiar with a measurement of insulation called the R-Factor. It’s related. The U-Factor is the inverse of the R-Factor. That is, 1/R, or One divided by the R-Factor.
R-Factor measures conductive heat loss and is technically:
(Temp Difference x Area x Time)/Heat Loss.
The larger the number, the better, walls are usually 13-23.
But, those measurements are in a lab, only measure for conductive heat, and don’t account for radiative heat that goes right through fiberglass, and on a windy 20 MPH day, a leaky wall performs no better than just the studs.
In Texas for windows, in Climate Zone 2, we look for windows with a U-Factor of .20 or less, and Infiltration (Draftiness) of less than .3 cu ft.
It’s a lot of info.

Oh, and by the way, I was telling this story to Bob Laws, a partner in a $4M restaurant renovation in Houston who had made his money doing movie catering.
He had catered the movie “The Doors” about Jim Morrison with Val Kilmer, Meg Ryan, Billy Idol, etc directed by Oliver Stone. He had two catering trucks get stuck in the sand as Oliver Stone kept driving in the desert looking for the perfect light.
He thought the story was funny because, on top of everything, Billy Idol was a vegetarian.
Sometimes I come off as Happy-go-lucky guy. But I know there is no standing still in this life. One must always strive to be a little better, learn a little more, give a little more.
A friend asked me to explain why it seems some builders don’t “dot their ‘I’s and cross their ‘T’s”.
There can be a number of reasons, and some aren’t intentional. I will point out that new construction is so much easier than remodel work and therefore takes a seasoned hand.
The following parable touched me the first time I heard it… so pardon if I get on my soapbox…
There is a story/parable I first heard from a close Freemason friend about a retiring carpenter who had told his employer of many years that he was ready to hang up his hammer and spend his time with his wife and family.
His boss was disappointed to hear his best and most loyal worker was leaving him and asked him to build one last house before retiring.
Disappointed, the tradesman agreed anyway, although his heart wasn’t in it. He let his commitment to quality fall: cut corners; ignored details; and failed to correct the workers when he saw shoddy workmanship. He even looked the other way when some of them substituted cheaper materials and pocketed the difference.
When the house was finished, his boss shook the carpenter’s hand,and with a huge smile gave him an envelope in which the carpenter found a “Thank You” card and the deed to the house he had just built.
He was ashamed he had misjudged his old friend and that he had to live in that house with leaky roofs, creaky floors, and a weak foundation.
The story of a Story of Character and about how the life we live in is built piece by piece by our daily choices.
Don’t we hope the builder who built OUR home built it as if he was going to live in it himself?
Is that our reality? Even with best intentions, the builder often isn’t supervising the jobsite every day. And, mistakes are made.
After a recent major hailstorm in San Antonio, I was visiting a jobsite and the foreman, short on workers, had hired his brother to help. At that moment his brother was showing how perfect he had butted the siding planks together without even a hair’s breadth gap.
At which point, his brother chuckled and said, “And it will be perfect, after you take it all down and re-do it, because it must have an expansion gap or when it gets hot, it will break. Sorry, brother.”
His brother meant well, but just didn’t know.
If you have ever done major remodeling or construction, you know that there are defined goal posts that, when reached, release more funds to the builder and his various teams.
The Foundation, Framing, Dry-In (the Roof is on and walls in place), Rough-In ( when the electrical, HVAC, Plumbing mechanicals are ready for inspection before the walls are closed), etc.
On site, there is a strong push to get to the point of “Dry-In” because the inclement weather can no longer stop construction, and there is the ability to “Lock the house”– so less likely materials and tools will be stolen.
At this point,the tradesmen on site are mostly framers and their contract is most often to the point of “Dry-In”.
So, in short, it’s because of “Jobsite Security” that the windows are put in place. Details are not considered and the framers certainly didn’t get formal training installation. He’ll use his nail gun when it should be screws, not waterproof, seal or insulate. Then, the dry wallers and finish carpenters will close it up unfinished and the exterior may not be caulked and sealed and weatherproofed before the siding crew closes it up.
If this sounds unlikely, note that in Texas drafty windows are one of the top complaints in new homes. And, while 100% perfection is unattainable– I’ve never had a large scale remodel without a “Punch-list”– pride in workmanship should always be evident.
Talk is cheap, right? I happen to have a review right to these points on a project I may detail on another post because it required an immense amount of personal growth and implementation of techniques of a very specialized type.
Build it Smart. Build it Right. Build it Once.
Want a Window you LOVE?
Replacing Builder Grade windows with upgraded Energy Star High Performance Windows is one of the best investments you can make to your home because inefficient windows are the largest energy wasters in homes in every Climate Zones. But, which ones are right? What do you need to know?
I’m a Native Texan and I wouldn’t dream of living in a house without Air Conditioning. But, for 6 years I lived in Ohio where there may be snow 5-6 months of the year. High temperatures and A/C don’t have the emphasis that they do here.
Different Climate Zones require different solutions. A Triple Pane window here in Texas would only save the average home about $50/year. We want to keep the heat out, not in. Therefore, we look for a window with low SHGC( or Solar Heat Gain Coefficients), and U-Factors with Low Infiltration (air flow through a closed window– draftiness) to ensure comfort and low utility bills.
Did you know that old builder grade windows are wasting up to 40% of your hard earned utility bill money? It’s going right out the windows.
The “Go-to” answer in the industry is to replace those windows with Vinyl framed double pane, Argon or Krypton filled, High Performance Low-E glass windows. Why Vinyl?
Because Aluminum, although 4x as Structurally Strong as Vinyl, is such a superb conductor of heat (1000X more than Vinyl), a regular Aluminum frame double pane window it performs horribly — almost the same as a Single Pane Window. That Aluminum frame makes a Thermal Bridge all the way around the perimeter, so the inside glass, even though it doesn’t touch the outside air, is almost the same temperature. When it’s hot outside, the inside pane is hot. When it’s cold outside, the inside pane is cold.
Is that just an energy bill problem? Nope. You’re right, the resulting condensation can cause wood rot and real damage to your home.
But, since Vinyl frame windows, especially in Texas’ high heat, aren’t very strong, they have to built thicker with hefty frames and sashes– It isn’t a look everyone likes.
There is a company in Texas that has the answer! A Thermally Broken Aluminum frame stops the heat — cold in its tracks. The image to the left shows the Thermally Broken frame sitting on dry ice to show how well it works.
And, its a great utility bill performer as far as Energy Savings with 3rd Generation Low-E insulated glass units and Argon gas fill.
Even better, they have extremely low air leakage, so “treated” air stays in the house and hot or cold air stays out. Finally! A narrow frame answer to often make that “hole in the wall” of a window more efficient than the wall itself.
And, because Aluminum is so much stronger, the window is more secure against break-ins or home invasions and is very durable over time with Lifetime Warranties on the frame and the seals. Look at the image to the right– try standing on Vinyl windows– it won’t be pretty.
The narrow Aluminum frame profile can make a taller window than is possible with Vinyl, and has an inch more glass all the way around the window for increased light and less frame heft. Architects and Designer love the higher “glass to frame” ratio.
There is another benefit.
Because Vinyl frame windows have so much heft, they look very different from the inside and outside. It is obvious that a window has been replaced so it is often “All or Nothing” and replacing all the windows at once may not be in the budget. This could keep you from a project you want to do.
What if you just have ugly windows? You know, hazy windows that have to be replaced because of seal failure. Or, they don’t open and close right, or are drafty or just plain need changing?
We can start with the high priority Bad windows, or the Upstairs windows where it’s really hot, or the South windows with high sun exposure… and do the rest at YOUR pace.
We can make it easy for you. Get a window you LOVE!
