Ready for Your Screen Test? All About Window Screens

Posted On Wednesday, Nov. 2nd, 2016


Seaway Manufacturing of Erie, PA, manufacturer of residential replacement windows, patio doors and sunrooms, presents “Look Into Your Windows,” an educational series designed to answer the most frequent questions about choosing replacement windows for your home.  In this installment, a look at window screens.

We briefly touched on window screens in the last installment on double-hung windows, but screens are one of the most-overlooked components of a window, and they’re worthy of a little more attention.

If you’ve had a window demonstration in your home or in a showroom, the screens were probably barely mentioned, if at all. Windows have screens. Screens keep bugs out. The end. Right?

Yes and no. Screens keep bugs out, yes. But the wrong screens keep too much air and light out as well. Newer screen designs offer more effective bug protection while allowing more light and air to flow through, and those are the main reasons to have your windows open in the first place: more air and a better view of the outdoors.

Consider not just the screening material but the frame that holds it in place. In many windows, this is a flimsy afterthought, prone to bending out of shape over time. Look for construction that’s just as sturdy as the rest of the window.

Double-hung windows have half-screens that cover the bottom sash area and lift up and down. Occasionally, a customer will request full screens; that is, screens that cover the entire window so the top sash can be lowered as well. Just bear in mind that a full screen is fixed in place and is a little harder to remove should you need to in order to reach outside. With casement or awning windows, the screen will always cover the entire opening.

Here’s what screens won’t do: they won’t prevent children or pets from falling out, so you’ll need to be vigilant in those situations. Use the window’s limit latches or safety latches to limit the opening of the window and prevent accidental falls. Screens also won’t keep someone from breaking in. A quality window has many security features, but the screen is not one of them. Take any claims of “locking screens” with a huge grain of salt.

Double-Hung Windows: The Popular Choice

Posted On Tuesday, Sep. 13th, 2016


Seaway Manufacturing of Erie, PA, manufacturer of residential replacement windows, patio doors and sunrooms, presents “Look Into Your Windows,” an educational series designed to answer the most frequent questions about choosing replacement windows for your home.  In this installment, a look at the most popular form factor for replacement windows, double-hung windows.

When it comes to the form factor of your replacement windows, there are plenty of options including casement windows, sliding windows, awning windows, bays, bows and more. But far and away the most popular choice is the double-hung window. What should you look for in a double-hung and why? Read on.

First, the name “double hung” simply means that both the top and bottom sash of the window are operable; that is, they both slide up and down. There are single-hung windows as well (only the bottom sash operates and the top sash is fixed in place), but these are more common in commercial and apartment settings.

If your home already has double-hung windows, and chances are pretty good that it does, you’ll probably replace them with the same type. (There are situations where you may want to consider other options, and we’ll address those in future posts.) Here’s what you can expect:

Easy cleaning: It used to be that when you wanted to clean the outside of your upstairs windows you’d have to get on a ladder. No more … both sashes on just about all modern double-hungs will tilt inward so you can easily clean them from inside.

Insulated glass: Each sash will have at least two panes of glass, sometimes three, with a sealed airspace in between for better insulating efficiency than your old single-pane windows. (For more on glass efficiency, see our previous posts here and here.)

Security: All but the narrowest windows should have two sash locks. Besides the obvious security benefit of a locked window, these locks pull the sashes together at the meeting rail for a tighter fit and better resistance against wind. The lesson: lock your windows even if they’re not reachable from the ground. Look for an interlock between the top and bottom sash, important for both security and to protect against air infiltration.

Venting: Better windows will also feature vent locks, which will fix the window in a partially open position but keep it from being opened further. This allows you to let in the fresh air without the fear of an intruder being able to enter your home through the opening. Locking the sash in a partially open position also minimizes the risk of a fall by a child or pet.

Screens: A screen is a screen, right? Not quite. Screening material can vary significantly from one window to another. A screen’s primary purpose is to keep bugs out, of course, but better screens will do two more things: maximize air flow and minimize the impairment to your view of the outdoors. One more note: screens are not a security measure, so don’t be taken in by a promise of “locking screens.” Window screens by themselves will not prevent someone from breaking in, or worse, falling out.

Lift Rail: This is simply the part you grab to raise or lower the bottom sash. There’s not a lot to it, except that on lower-end windows the lift rail can have a pretty flimsy feel to it. Look for a lift rail that’s an integral part of the sash, not snapped on or glued in after the fact. These will be more durable and longer-lasting. Be sure to actually operate any window you’re considering and make sure it’s sturdy.

What Do U Value? A Glass Efficiency Primer

Posted On Wednesday, Aug. 24th, 2016


Seaway Manufacturing of Erie, PA, manufacturer of residential replacement windows, patio doors and sunrooms, presents “Look Into Your Windows,” an educational series designed to answer the most frequent questions about choosing replacement windows for your home.  In this installment, we offer an explanation of window glass efficiency standards.

As if shopping for replacement windows wasn’t confusing enough, now you’ve seen the term “U-Value” for the first time.  What does it mean?  Is it like the R-Value rating you’ve seen on those bundles of pink insulation? Yes.  And no.

In case you’re getting ready to take the SAT, here’s the official definition: A U-Value – also called a U-Factor – is the overall heat transfer coefficient that describes how well a building element conducts heat or the rate of transfer of heat (in watts) through one square meter of a structure divided by the difference in temperature across the structure.

Glad we cleared that up.  Now, in English, the U-Value of a window or other building component is a measure of heat loss.  R-Value is a measure of resistance (the “R” in R-Value) to heat loss.  Here’s why that’s important: with an R-Value a high number is better.  This is easy to see in the insulation aisle at your local home center; the higher the R-Value, the thicker the insulation and vice versa.

But because U-Values measure thermal loss, a lower number means a more efficient window glass package, and that number will appear in manufacturers’ literature as well as the NFRC label affixed to every new window.  All other things being equal, a window with a lower U-Value will insulate better.

Bear in mind, however, that all other things are not necessarily equal.  While glass makes up the largest area of a window, the construction of the window also has a big impact on how well it will resist the elements.  The most efficient glass, if installed in a poorly-constructed window, will not be very effective.  Be sure to evaluate the entire window and not just the glass.

One more note on the numbers: on that same NFRC label you’ll see a rating for Solar Heat Gain Coefficient (SHGC).  This is similar to the U-Value except that it measures only how well the product blocks heat caused by the sun.  The number will be between 0 and 1, and again, lower is better unless you’re in a region where heating days outnumber cooling days quite substantially.

One final note: the right answer for your home will depend in part on where it’s located. The EPA’s Energy Star program has divided the country into climate zones based on the number of heating and cooling days for each. A window or door that’s appropriate for the Northern Zone might not be right for the South-Central or Southern Zones. Here’s a link to a map showing the Energy Star climate zones, or use this tool to enter your state and county.
