Your Windows & Bad Weather

Windows are one of the most vulnerable parts of your home during extreme weather conditions. Thunderstorms, windstorms, rainstorms, tornadoes, and other disasters can break them, however, if they are old or poorly installed the inside of your home is at risk.

Sealing gaps and small openings in your older windows using a weather-stripping agent can help prevent a flow of water or a draft coming from the outside. Adding weather-stripping to window sashes also helps regulate the heat or coolness inside the house. This helps ensure that your entire household can still be comfortable despite the weather outside.

It is not uncommon for even the best, most well-designed windows to let some water through after a severe rainfall. A design feature of modern windows is the addition of water drainage channels.

Old, poorly installed or bad windows will pool that rainwater and allow it to leak into the home. Drainage channels are designed to move water away from the wall, and prevent leaks.  They also prevent pooling that can result in moisture damage.

When talking about water drainage in modern windows it is important that this water stays between the operable parts of the window without penetrating the sealed unit or frame components.

As with most things related to high-efficiency windows, correct installation is crucial in ensuring the drainage channels function properly. If the window is not level, an excessive amount of water will pool on one side of the window. Similarly, if a window is not installed plumb into the opening, with the panes tilting inward or outward, the water may not be allowed to drain away from the frame.

While drainage channels are suitable for all operable windows, slider and double slider windows tend to experience the most issues with water drainage channels. This is because their design integrates more grooves for water to collect in.

An extra feature that comes standard with windows that have drainage channels are the exterior drainage flaps. Essentially these flaps act like a one-way door and let the water out without allowing insects to enter your home.

Remember, proper water drainage is essential to the longevity and efficiency of your windows. Ensuring that as little water as possible collects in your windows will prevent damage to your house and save you money in the long term!

 

 

 

What is a Window?

Windows provide our homes with light, warmth, and ventilation, but they can also negatively impact a home’s energy efficiency. You can reduce energy costs by installing energy-efficient windows in your home.

If your home has very old and/or inefficient windows, it might be more cost-effective to replace them than to try to improve their energy efficiency. New, energy-efficient windows eventually pay for themselves.  When properly selected and installed, energy-efficient windows can help minimize your heating, cooling, and lighting costs

If you’re constructing a new home or doing some remodeling, you should take the opportunity to incorporate your window design and selection as an fundamental part of your design plan and for building an energy-efficient home.

A window’s energy efficiency is dependent upon all of its components. Window frames conduct heat, contributing to a window’s overall energy efficiency, particularly its U-factor.  (U-factor measures the rate of heat transfer. The lower the U-factor value, the better the product insulates.) Glazing or glass technologies have become very sophisticated, and designers often specify different types of glazing or glass for different windows, based on orientation, climate, building design, etc.

Even the most energy-efficient window must be properly installed to ensure energy efficiency. Therefore, it’s best to have professionals like Northern Windows and Doors install your windows.  Window installation varies depending on the type of window, the construction of the house (wood, masonry, etc.), the exterior cladding (wood siding, stucco, brick, etc.), and the type (if any) of weather-restrictive barrier.  Windows should be installed according to the manufacturer’s recommendations and be properly air sealed during installation to perform correctly.

  • Awning – Hinged at the top and open outward. Because the sash closes by pressing against the frame, they generally have lower air leakage rates than sliding windows.
  • Casement  Hinged at the sides. Like awning windows, they generally have lower air leakage rates than sliding windows because the sash closes by pressing against the frame.
  • Fixed – Fixed panes that don’t open. When installed properly they’re airtight, but are not suitable in places where window ventilation is desired.
  • Hopper – Hinged at the bottom and open inward.  Like both awning and casement, they generally have lower air leakage rates because the sash closes by pressing against the frame.
  • Single-Hung and Double-Hung  Both sashes slide vertically in a double-hung window. Only the bottom sash slides upward in a single-hung window. These sliding windows generally have higher air leakage rates than projecting or hinged windows.
  • Single-Sliding and Double-Sliding – Both sashes slide horizontally in a double-sliding window. Only one sash slides in a single-sliding window. Like single- and double-hung windows, they generally have higher air leakage rates than projecting or hinged windows.

Energy Efficient Windows for the Summer

Summer is nearly upon us, and that means that higher temperatures are on the way. It’s usually at this time of the year that you start running your air conditioner in an effort to keep your home cool and your family comfortable. Long summer heat waves can cause you to turn up the AC for extended periods of time, and this almost always leads to higher electrical bills in the summer time. It can be downright shocking to find out just how much you can easily pay over the course of one summer when it comes to air conditioning use. Fortunately, there is a way to reduce the amount of air conditioning your home requires to remain cool; energy efficient windows are designed to keep cold air in and hot air out in hot weather. These windows are a great choice if you are looking to save money on your electrical bill this summer.

How are Energy Efficient Windows Different?

Energy efficient windows are different from regular windows in the sense that they are designed for more than just looking good. They are built and installed with energy efficiency in mind and help to reduce the amount of heat entering the home in the summer and the amount leaving the home in the winter. They are designed to reduce your home’s use of energy all year round.

How do Energy Efficient Windows Work?

A primary way energy efficient windows control the amount of heat entering and leaving your home is through glazes, coatings, and tints. Tinted window glass absorbs a large amount of incoming solar radiation, reflective coatings reduce solar radiation transmission, and some types of glazing help reduce solar heat gain. Low-e coatings are microscopically thin metal or metallic oxide layers that are placed directly on the surface of window glass and work to control heat transfer through that glass.

Another component of energy efficient windows is window frames. Window frames conduct heat, contributing to the overall energy efficiency of a window. Also, how an energy efficient window is installed is very important. Poor installation can lead to air leakage and an inability to save energy. When putting in your new energy efficient windows, it’s best to have a professional handle the installation.

Which Window Type is Best?

With all the different types of windows available on the market, it can be hard to decide which one is best for energy efficiency. Hopper, casement, and awning windows generally have lower air leakage because they are hinged and are designed to press right against the frame when closed, creating an air-tight seal. Single and double-hung, and single and double sliding windows tend to have higher air leakage due to the fact that they are closed by sliding and are not on hinges, making it more difficult to form that air-tight seal.
Energy efficient windows are your best friend during the hot summer months. You can expect to see a smaller electrical bill when you decide to install new energy saving windows in your home.
