New Storm Sush
Does Much to Cut
Heot Loss in Home
By HILSON MUNSEY,

AAAASOAN NAOANSNAs
Much can be done to conserve
fuel in the wintertime by the cor
rect treatment Of windows. Win
dows are, of course, the greatest
factor in heat losses in the home.
A single pane Of glass is about
as effective as a hole in the wall,
except that it will keep out
the wind. If this heat loss can be
stopped, or at least modified and
brought within bounds, then there
will be a decrease in the fuel bill
and added comfort in the house.
Storm sash is one way Of i'm
proving the condition, and a modi-
fication of this idea that will be Of
benefit in both winter and summer
is provided by a sash that has inter-
changeable glass and screening.
This particular unit has both
upper and lower sash which can be
used In combination to provide
draftless ventilation in the winter
and rain-proof ventilation In the
summer. This Is done by the use
of q combination Of the glass and
of the screening.
Keeps Out the Rain.
If the screen is placed at the
lower half of the window and the
lower sash is pulled down, rain
cannot drive through the window
to ruin the rugs and the wood
work. Then by half dropping the
upper sash and inserting the glass
in the storm sash a current OF air
can enter the room through the
screen and pass upward to the
upper part Of the window and so
into the room. That will keep the
air freseh and remove the danger
of drafts. Inasmuch as the upper
part Of the storm sash IS glassed-m,
the rain cannot enter. With the
glass inserted in both upper and
lower sections the storm sash acts
as a regular storm unit. This ar
ranRement makes window washing
safe and simple because the glass
insert can be removed and washed
on both sides right in the room.
The framework Of this storm sash
Is metal and is attached perma-
nently to the frame Of the window.
The glass and the screening also
are metal The change
from screening to glass can be mace
in less than a minute. All joints
are welded for added strength ana
long life. The screening units are
Of l6 mesh bronze.
Window Insulation.
Another method Of saving fuel
and reducing the heating bill is by
the use Of q double-glassed WINDOW.
These insulating units consist OF
two panes Of glass separated by an
air space. This space is hermet-
tcally sealed with metal and Is q
quarter Of an inch wide. The glass
used may be either a double
strength best quality Of window
glass or polished plate glass that
NAV be Il, 3-16 or 4 Of an inch IN
thickness. II the double glass IS
to be used indoors an air space
of half an inch can be used. The
air space between the two panes
of glass is dehydrated and then
the window is sealed. This means
that there can be no collection OF
moisture on the insides Of the
glass to obstruct the view. 1t also
prevents the collection OF moisture
on the glass In the room. On the
ordinary windows OF the single
glass variety this moisture collects
and then drains down onto the
window frame and freezes. AS the
Ice melts the water seeps into the
framework OF the window and ruins
the paint. If 1t happens often
enough it will rot the wood.
The glass is made either clear,
tinted or colored. This gives q
selection that will cover practically
any need in the home. The colored
glass Is made in many decorative
designs and it can be used Tor IN
terror decorative purposes apart
from the use to which 1t Is put IN
windows.
There are a number OF sizes
available. In the regular glass the
size varies from 80 by so inches to
3 by 8 inches. In 3-l6-inch the
sizes are 48 by u inches to u by IL
inches. and In the A-inch plate
glass from u by s6 inches to II
by IL inches.
