Determine air filtration in sash replacement windows
While making plans to purchase the
new sash windows, there are lots of important factors you need to consider in
order to make your good purchase. Many sash window sales man always point out
some obvious things: their great aesthetics, the "cool features" such
as tilt wash windows, and their proper warranty period. As most of the consumers
try to get some more energy conscious, but there is another factor comes at the
forefront while choosing sash replacement windows: and this is the window
ratings. While there are lots of window sales people and they focus on two big
things: U values & the Solar Heat Gain Coefficient. And after that there is
another essential factor to consider while selecting these windows and this is
the air infiltration.
How
to determine air filtration in sash replacement windows
There is a best scientific way
introduced some years ago in London which helps people to determine the proper
air infiltration beyond standing next to their windows and then calling it
drafty. Leakage of air is basically measured by the careful testing of some
highly standard sized sash window. This sash window is perfectly installed in the
testing wall. And a vacuum of about 75 pascals (1.57 psf) is carefully applied
on the single side of this test sash window. This would correspond to approximately
26 mph wind blowing in a perpendicular direction to this window. Flow meters
are also efficiently positioned in order to measure the amount of air leakage. This
is then systematically divided by the net area of the sash window in order get
a reading in cfm/ft2 which is closest to tenth. The best possible rating is
usually 0.1, as I wouldn’t round to 0 only. If this process seems little
complicated then you take the help of sash replacement experts who will help you not only installing the windows but
also perform air filtration test for you.
Solutions
for heat gain and loss
Air infiltration is the biggest
concern for home owners while considering the sash window replacement in your
home. It is also a major culprit for the heat gain and loss in your home. A
periodic window wouldn’t seal as firmly and will create the possibility for air
to get enter into your house. Hence people refer to this as a "drafty"
condition of window in winter season, because the cold air is simply entering your
room. And that heat may enters your house in the summer season through
different cracks, so there are lots of people who confuse this for the heat
coming in through some inefficient glass. That’s why people choose professional
solutions for sash window draught proofing in order to make their areas completely draught free and to retain
the heat gain and loss in perfect manner.
Does
the poorly maintained doors are also responsible for heat gain and loss?
Yes, if your doors are poorly
maintained and have draughts and rattles or in damaged condition, then I think
you need the help of door services
in order to make your areas completely draught free and to control the amount
of heat gain and loss in best way possible.
Pay attention to all air
filtration sources and areas so that you can save your pockets on unnecessary
maintenance of your home.
