Windows are a huge source of energy loss in today’s homes and
businesses. Basically, windows are giant holes in your walls. This
allows both solar energy and cold temperatures to be transferred
into your home or business. While we all need the ability to allow
natural light in, we don’t need to be throwing money out those
windows on increased heating and cooling costs. One such way to
reduce heating and cooling costs in both residential and commercial
building applications is by installing energy efficient windows.
Many times, when security or privacy is a concern, traditional
windows do not provide the protection that may be required. For
these applications, glass block windows are typically installed.
Glass block windows are known for their ability to stand up to
would be intruders and to keep prying eyes out, but did you also
know that they can be energy efficient? If energy efficiency is
important to your new construction or remodeling project, you may
want to consider installing energy efficient glass block windows.
The benefits of installing energy efficient windows aren’t just limited to a reduction of heating and cooling costs.
For builders and architects that have been charged with decreasing
their client’s carbon footprint, energy efficient windows are a
must. This is especially true for construction projects that are
vying for LEED Certification. Using energy efficient glass block is
a great way to earn LEED points. Not only are these windows energy
efficient, but they are also constructed of green materials. Also,
glass blocks that are manufactured by the Pittsburgh Corning
Company are manufactured within close proximity to many Midwest
cities, which further contributes to LEED points.
When choosing to install energy efficient windows, it is important
to understand the four ways that a window can transfer heat in and
out of a building. Once you have a grasp on the basics, you can
begin to understand how the energy efficiency of glass block
windows is measured.
· Convection: This is the loss of heat between the air in a
building and the air outside through the glass of the window.
· Radiation:Solar radiation enters the building in the form of
heat. Infrared radiation transmits warm interior temperatures to
· Conduction: Is the transfer of heat energy through the solid
materials in a window’s frame.
· Air Leaks: When air passes between a wall and the window frame,
heat is transferred both in and out of a building.
Energy efficiency in traditional windows can be measured in a
couple of ways. They include measuring a window’s U-Factor and
Solar Heat Gain Coefficient. The same is true for glass block
· U-factor:This is a measurement of the rate that a window
transmits non-solar heat or the thermal conductivity of a window.
· Solar Heat Gain Coefficient (SHGC):This is the measurement of the
radiation from the sun that is transmitted into your home through a
Traditional window manufacturers use a variety of techniques to
increase a window’s energy efficiency. The use of multiple panes of
glass, gas fills between panes, and Low-Emissivity (Low-E) coatings
are all common ways to reduce the transfer of heat between the
interior of a building and the outside. Glass blocks, however, are
already very energy efficient. Each glass block is like a mini
double paned window. Glass blocks are constructed by taking two
pieces of glass and fusing them together with extreme heat. This
process creates a vacuum of air on the inside of the block. This
provides insulating properties that are better than a traditional
single pane window.
Energy efficient glass blocks take this process a step further.
Pittsburgh Corning places a glass pane with a Low-E coating in the
middle of all energy efficient glass blocks. This provides the
following three benefits:
· Keeps buildings warmer in the winter and cooler in the summer
· U-Value is increased over that of regular glass block
· Solar Heat Gain Coefficient(SHGC) is increased by 60% of that of
regular glass block
Energy efficient glass blocks can be installed in one of two ways. They are either installed in
a prefabricated frame, or they consist of an un-framed,
prefabricated panel that is mortared to the opening of a window.
Below are the U-factors for Energy Glass Block Panels.
· Un-Framed glass block panels have a U-factor of 0.34
· Framed glass block panels have a U-factor of 0.38
For those that are still on the fence on whether energy efficient
glass block windows can be as efficient as traditional windows,
here are some surprising statistics. According to the United States Department of Energy, energy efficient glass block windows can outperform many types of
traditional windows. Listed below are the U-Values of traditional
window types with either a wood or a vinyl frame and an insulated
· Double paned glass with ½ inch air space – U-Factor = 0.48
· Double paned glass with ½ inch air space with 0.20 Low-E coating
– U-Factor = 0.39
· Double paned glass with ½ inch air space with 0.10 Low-E coating
– U-Factor = 0.37
Pittsburgh Corning energy efficient glass block window panels have
been independently tested by the National Fenestration Ratings
Council(NFRC) and the American Society for Testing and
Materials(ASTM) and received the following results:
· ASTM C1363 thermal transmittance (unframed U-Value of 0.34).
· NFRC 201-2004 Solar Heat Gain Coefficient of 0.27 (framed) blocks
assembled with a silicone spacer system.
· ASTM E2190 – 08 Standard Specification for Insulating Glass Unit
Performance found the glass block showed no evidence of
condensation when tested to -60°F.
Independent and government testing have all concluded that energy
efficient glass block can be as effective and even outperform
several types of traditional windows when it comes to energy
conservation. While this is impressive, glass block windows provide
many other added benefits that you simply can’t get with regular
windows. Some of these benefits include:
· Added Security
· Elegance and Beauty
Patterns for Pittsburgh Corning energy efficient glass block
windows include Decora™, Delphi™, IceScapes™, and Vue™
· Reduced sound transmission
· Resistance to graffiti
If any of the above is important to your building or home, glass
block windows are an excellent choice. The use of glass block is
ideal for use in commercial businesses as well as residential homes
that require a versatile solution that traditional windows can’t
provide. When looking for a green building material that can help
to reign in heating and cooling costs, look no further than high
efficiency glass block windows.
