Everyone loves a bay window for the obvious reasons. It punctuates the room and brings the outside in, but what a difference this bay window renovation will make.

From an ordinary bay window above that we have seen in thousands of homes, to the inspiring full height, floor to ceiling, Marvin window in this breakfast room to the right. I'll show a photo of the finshed exterior in a couple of weeks.

In case you missed the New York Times recently, as I did, there was a feature on Marvin Windows that tells the story of this family owned company in our currently challenging economy. The article confirms not only why they are a good employer, but gives me affirmation that their commitment to their employees translates into the exceedingly high quality of their product.

Windows are definitely one of the "glass half full / half empty" situations (pun intended). The views, the ambient light and architectual relief windows that windows provide cannot be replaced. Windows let us experience the outside elements without sensing the heat or cold - but how do yours feel?

If your windows are 5 to 10 years old you might start looking at them. Changes in technology for windows and exterior doors have been dramatic in the past decade. There are compelling reasons to consider changing older windows in your home. Consider the following examples.

The photo on the left shows a window with a broken seal. Windows are made with two panes of glass and the air between the two panes acts as an insulator and is often filled with argon gas, which is effectively a super-insulating gas. When the seal fails, the insulating gas is released and air can freely flow in and out of the space between the two panes. This invading air between the panes of glass can contain varying humidity and pressure. The result is what appears to be condensation or clouding between the two panes that cannot be cleaned. The only solution is replacing the entire window.

The photo on the right shows a door jamb with excessive rot. Old and rotten wood parts are often the primary reason to replace windows and exterior doors. Water can easily get into the home causing mold and mildew. One might consider repairing the bottom of the door jamb with a synthetic material but one should determine if any function of the door has been compromised by the rot and water intrusion first.

The most obvious evaluation is simply to feel if there is cold air coming through your windows. Clients say they could see their curtains move on a windy day before we replaced their windows. If you feel that your home is significantly more comfortable when you pull curtains or window treatments over the windows, then you really should consider replacing your doors and windows. All this plus the evident energy savings make replacing your doors and windows an easy decision.

I am both proud and excited about a campaign Natelli Homes has organized with the Capital Area Food Bank as our focus for the next year.

Hunger is a staggering issue in our community. This condition is an unfortunate and often overlooked result of our country’s economic status. Poverty levels have reached new levels and thousands of people in our area simply don’t have access to appropriate food sources and proper nutrition. The CAFB serves almost 500,000 people each year through its non-profit partners. Surprisingly more than half of the households assisted by their efforts have at least one employed adult and only 5% of the recipients are homeless. Hunger and food insecurity are quickly reaching into households that were previously self-sufficient. Sadly, the numbers of children affected are an increasing component of the statistics.

Natelli Homes hopes to make continuing donations to the Capital Area Food Bank through the installation of replacement windows and doors for our clients. Our “WINDOWS FOR HUNGER” campaign will provide a constant source of funding for the programs at the CAFB. We hope to introduce our clients to the successful efforts made by the Food Bank in our area. There are many ways to contribute to the CAFB, both through volunteering and donations.

I encourage you to learn about the Capital Area Food Bank by visiting their website at www.capitalareafoodbank.org

Please share the attached coupon with anyone who might be interested in assisting the Food Bank when they install new windows or doors in their home. Look for similar opportunities on the Natelli Homes FaceBook page in the near future.

"A picture is worth a thousand words"

We have seen and heard this phrase for decades, perhaps centuries, and I really doubt anyone questioned its meaning because it is so obviously true.  Whether conceived by Frederick R. Barnard in the publication, Printer's Ink, in 1921 or it truly evolved from a Chinese proverb ("a picture is worth ten thousand words") or perhaps it should be added to the many credits of Confucius, it needs no explanation.

With that in mind, tell me what you think:

Natelli Homes is finishing a replacement window project in Potomac, MD.  The painters are touching up the new trim and casings and the windows are being cleaned, soon ready for the installation of the window treatments.  I asked the client how things were going.  Without hesitation he said, "I immediately felt the difference".  The house is measurably warmer in every room.  The cold air whistling through the old french doors is gone and the storm windows filled with bugs and dirt are no where to be seen - the house is quieter, warmer and feels like new.

In this home, rather than install insert windows, we did full replacements because the existing windows were so poorly insulated around the perimeters. We filled the jamb-space with expanding insulation and then applied new trim on all the interior surfaces.  Rather than "picture frame" the windows with casing, we installed proper sills with returns and a back-band on the casing to really make the trim punch.

One of the aesthetic benefits is without a doubt the architectural improvement of the windows.  In the photo on the right, look at how the grilles add significance to the window.  We elected to space the lite opening of each window a bit larger than the standard sizes offered by the manufacturer.  Having larger openings enhances the view but still gives the window the detailing it needs.  The grilles have clean profiles and the arrangement resonates with tradition.  Even the shadows from the muntins add character to the room.

It's easy to justify replacing windows and doors in a home.  Just make sure you sweat the details or your investment may not reach its full potential.

There are many reasons to replace old windows and doors in a home, but the architectural value of windows can't be overlooked.  Window grilles in particular change and enhance the persona of a home.  Removable grilles can be provided for ease of cleaning,  grilles can be sandwiched between the panes of glass so they provide an apparent division of divided lites, but the most pronounced and historically accurate use of grilles is a permanent application on the inside and the outside of the glass.  This type of grill, also known as "Simulated Divided Lite", produces the authentic look of a traditional window with milled wood and clad components separating the pieces of glass.  Windows with Simulated Divided Lites are significant, they have appropriate mass and are recognized by any layman as quality products that enhance the character and value of the home.

In this home in Potomac, MD, we installed new JeldWen custom sized clad windows with true divided lites.  The existing windows in the home did not have any grille divisions in the glass.  The window openings were effectively black holes in the facade - the home needed some architectural content.  Including windows with grilles immediately changed the look of the home.  The window openings took on a character;  the grilles added color and visual interest to the front elevation.

Using replacement windows with grilles is an easy but often overlooked change to the home.  We get used to how things are sometimes and need to consider options that may not have been considered before. There is a lot more about the architectural potential of windows that we will cover in a future post such as the size  and layout of the window divisions, the type of grilles to use and even the color, but for now just admire the architectural transformation of this home with the simple addition of grilles in the windows.

"Just do it!" - a notable trademark of Nike that catches everyones eye.  I always wanted to make tee-shirts for my employees that said, "Just do it right!"  I paused for fear of trademark infringement, but still like the message.  I am confident that our team thinks that way, even though we don't have the tee-shirts.

In the case of replacing a dormer window, it would have been easy to plug the new window in and consider the job done, but that would have been a huge disservice to our client.  The trim around the window was rotting and the siding was all but deteriorated.  I wonder how much water was getting into the home through the trim and siding alone.

We chose to remove everything, down to the exterior sheathing so we could observe the flashing and ensure that the dormers were flashed, sealed and water and air infiltration were managed properly.

The new finished product assures our client of a weather-proof installation that will stand the test of time.  We used synthetic exterior millwork, 70% Kynar 500® cladding on the Marvin Windows and a cement based siding on the sides of the dormer. The Kynar cladding from Marvin Windows and Doors comes with a 20 year warranty.  The synthetic trim and cement siding takes paint well and resists rot and deterioration for years to come.  The future maintenance requirements will be minimal.

Always look at the bigger picture and don't cut corners on a significant investment such as window replacements.  Find a contractor that is familiar with the best products and procedures in your marketplace.  Evaluating all the issues for a client up front is a detail that can't be overlooked.

If you are considering replacing the windows and exterior doors in your home, make sure you carefully evaluate your investment.  New windows and doors can be one of the most significant energy efficiency improvements one can make in a home.  The current tax credits add additional incentive and the investment can arguably break even in a reasonable number of years.  All this plus the additional comfort you notice in your home on a daily basis is enough to pick up the phone and call one of the many window replacement firms in the Washington, D.C. market.

Many window companies offer replacement kits, sash packs or inserts.  These solutions may appear to be good values and offer less disturbance to the existing interior spaces but consider what you are missing.  If one leaves the old existing frame in the opening and just installs new sashes with a frame insert kit, think again about the quality and true energy efficiency of your investment.  A tremendous amount of air enters around the frame of a window, especially in older homes.  There is very little insulation, if any, around older windows and air and water can still enter the home even with a new sash or insert kit.

Look at the adjacent photos of existing windows in a home.  There is significant mold, water intrusion, air penetrating the home and even bug and ant nests.  If one used insert windows or a sash kit, these conditions would still be there unbeknownst to the home owner.  After a significant investment in new windows, wouldn't you be shocked and disappointed to know these issues were still there!

There is really only one way to properly replace a window.  Replace the entire window and frame - PERIOD.  No inserts, no sash packs, no cutting corners to save anything existing.

Compare this photo of a properly flashed and weatherized new Marvin window and frame to those examples above.  Vikor adhesive flashing is wrapped from the outside sheathing into the opening preventing water intrusion.  Expansive foam has been injected between the window jamb and rough opening. This foam completely blocks air and pests from invading the home.  The foam will be trimmed flush with the window frame prior to the finished trim installation.

Which would you want in your home?  A sash pack or insert window kit which does not address significant existing issues around the window frame or a weather-tight, pest free installation that protects your investment?  The answer is pretty clear to me.

It must be hard for a consumer to decide how to select replacement windows or windows for a new home.  How do you start, where do you start and who do you trust for such an important investment?  All the manufacturers claim high efficiency glass, tax incentives and new and improved technologies.  In my career at Natelli Homes, which is going on 25 years in residential construction, the window and door industry has grown and improved the most.  The standards for all the major manufacturers are so much improved that I would venture to state that there are arguable financial and performance benefits to replacing windows that are only 10 years old.

Windows and exterior doors are the biggest contributors to heat and energy loss in a home.  People notice it more in the winter when we can feel the cold spots and drafts around windows and doors, but imagine how much is also lost in the summer when we are not quite as sensitive.  Poor performing windows and exterior doors contribute to an immeasurable amount of energy loss in our world.

Again, where does one start?  You might start with the U-value of a window which is a measurement of 4 combined ways windows lose heat.  This is a standard by which a homeowner can evaluate the performance of manufacturers on an even playing field.  Simply put, the U-value of a window combines the heat loss of a window through (1) radiation, (2) convection, (3) air leakage and (4) conduction.  The lower the U-value the better performing the window is.

I found a great sketch in an article by Paul Fisette in Fine Homebuilding.  Paul Fisette is director of the Building Materials Technology and Management Program at the University of Massachusetts in Amherst, MA (www.umass.edu/bmatwt).

Natelli Homes recently completed a full window replacement, also called a full tear-out, on a home with a Mansard slate roof.  This was particular difficult because a Mansard roof-line flares out at the bottom of the window, which allows significant potential issues with water and air infiltration.  If not done properly, water could easily get in the bottom of the window beneath the sill and cause leaks in the home below the windows.

As you can see in the photos, the existing windows were old aluminum frames which conducted large amounts of cold air into the room.  These older aluminum windows with single pane glass are an enormous source of heat and energy loss in the home.  I expect the client to feel an immediate difference in the temperature of the room.

We installed Jeld-Wen premium siteline EX windows with Dual Low-E Argon gas.  This is a window with a U-value of 0.30 compared to maybe 1.5 or more for the old single pane aluminum framed windows.  In layman's terms the new windows will improve energy efficiency by 5 times plus the improvements in the installation methods which adds another level of energy savings which cannot be quantified, but may be equally significant.

We worked carefully with the client's roofer to ensure the windows were flashed and water was properly mitigated.
