Tips for Window and Glass Replacement
For home and property owners, changing your windows is a major investment. We beleive the more the
home owner is educated in the area of window renovations, repairs, replacement and installation, the better off
they will be. We are pleased to have curated this blog post from http://TrustedPros.ca. Feel free to visit

Northern winters are hard on the fuel bill and no other place in the home will give back more money in
energy saving than window replacement. With the insulation value of an outside wall for a typical twenty year-old
home at R-15, the fact that the windows are only at R-2 shows where most of the heat is escaping. This is why
windows are rivaling both bathroom and kitchen remodeling as the most popular renovations. However, there are other
reasons that homeowners are looking for new replacement windows.
Reasons for Window Replacement in Northern Climates
Old Age of Windows
People change out windows for many reasons but age is a prominent reason especially with wooden sashes. The
temperatures in some northern areas can swing between minus forty-degrees and plus forty-degrees Celsius and this
is not including the freeze-thaw cycle. These weather characteristics are hard on building materials especially
wood which is porous and absorbs moisture. As the oils are leached out the wood shrinks and become brittle opening
up air leaks between the wood and the glass. Not only that rot can set in exposing cavities where water can leak in
and damage the walls under the exterior cladding like vinyl siding. This can go unnoticed for years.
Another problem encountered with old windows is failure of the opening mechanisms. This includes the sliders on
aluminum windows and window cranks. Corrosion, paint build-up and dirt can also affect the performance of the
windows and prevent them from sealing properly.
Preference and Style of Windows
Many northern Arizona homes have aluminum windows or old-style, vinyl clad windows that do not go well
new home designs especially of there has been major home redecorating on the inside. The plain aluminum can look
corroded and, if polished, it shines. New white-vinyl windows look bold and clean and add a great look to both the
interior and exterior of a home.
Vista and Window View
Many older homes were built with small windows to conserve energy and because windows were relatively expensive.
New models of windows can be manufactured to fit almost any size of wall and this can bring more of the outside
light and view into the home. Others had large, picture windows whose life expectancy was almost at an end or the
seals were already compromised. This causes water vapour between the panes.
Energy Savings of Windows
With fuel oil skyrocketing and natural gas following close behind homeowners are beginning to look at their
windows as energy-loss areas and are searching for ways to lower their heating bills. This is because glass is a
natural conductor so that, with one-paned, glass windows, warmth from the inside of the home was easily drawn
outside. With the advent of double-paned windows the heat loss slowed down but convection currents between the
glass panes did nothing for the insulating quality. The reason for this was that the interior pane was warm and the
exterior one cold and this created a way to vacuum out heat from the inside and transfuse it to the outside.
Acoustic Qualities of Windows
As most people live in metropolitan areas there are always offending sounds around the home like traffic or
aircraft. A single pane of glass will cut down the sound quite well. When the panes are tripled the acoustic
qualities of the window increase to almost the value of the wall.
New Replacement Windows Pay for Themselves
Home insulation is usually measured in r-values. This is a number that correlates to the amount of heat that is
prevented to pass through a surface. The higher the r-value the better the insulating qualities. In the 1980's the
r-value of the walls was around R-15 while the double-pane windows barely made R-2. With the cost of fuel rising
every winter this is the cause of a lot of heat wastage. New technology in window manufacture has raised the
r-value of windows considerably.
Triple Pane Window Construction:
By placing three panes in a window system the inside heat takes longer to penetrate the window keeping the room
warmer and the furnace off longer. Windows with the interior pane made of plastic are more efficient because
plastic is a thermal break and slows the conduction of heat.
Low Emissive Window Coatings:
In warm climates radiant foil is used in attics and under exterior cladding like vinyl siding to keep up to 97%
of the heat out of the home. This can also be used to keep heat inside the home and so a transparent film is coated
on the panes.
The convection current inside the windows are slowed by heavy, inert gas. Krypton and argon gas slow this cycle
down keeping more heat inside the home.
Thermal Break Sashes in Windows:
Even though a wood frame is a decent material to prevent heat from going outside a vinyl window with a foam core
is better. The rest of the frame is channeled with air spaces.
Get a Professional to Install Your Windows
To get the best results new windows should be installed by a professional. In many cases the manufacture will
not warranty the window unless a registered installer puts in their product. This is because there are so many
procedures to make the window secure that missing one cold cause leaking within the walls or an unstable
