New Windows
Two Layers Of Glass
With Deod-Air Space
Prevent Condensation
BY LAWRENCE CROLIUS.

Insulation has recently been applied
to new type of window glass which
is now available for use in modern
homes. You are probably we'll ac-
quainted with the remarkable man.
ner in which heat is prevented from
passing through the walls of the
picnic beverage container and now
you can control the entering or
leaving of heat through windows of
your house in a similar manner.
Ordinary glass windows might
Just as we'll be left open for all the
good they do in keeping precious
heat from passing from your home
out into the great outdoors. Hence
two layers of glass have been sealed
together in this new type of window
insulation with a thin but highly
efficient layer of dead-air space left
in between. The two panes are
welded together with metal into an
easily installed unit which may be
set in place in either a swinging or
sliding sash.
Like Answer to Prayer
To present condensation, which
proves to be pretty much of bug
aboo to many home owners who try
to maintain a high level of humidity
with their new air-conditioners,
these insulating units are the answer
to the home owners prayer" In
stead of having fine stream of
moisture flowing from nicely
steamed-up window panes, these
windows are said to remain clear
and unsullied. This is, of course,
due to the ability of the inner pane
to remain at approximately the same
temperature as the room air and
not present frigid surface where
humidity loves to condense.
Some home modernizers have ex-
perienced little trouble with ordin-
ary double glazing, or storm Win
dows, because of steaming up on the
inside between the two layers OF
glass. This difficulty is eliminated
according to the makers of these
units by filling the space with de-
hvdrated air, no less, so that there
is little or no moisture to cause any
trouble.
Nice in Summer, Too.
Don't forget. either that windows
of this type are just as nice to have
around in summer as they are IN
winter When the temperature out
side begins to soar again they will
effectively prevent the torrid heat
waves from passing through and
turning the house into an oven.
Thus you can leave them in place
the year around, clean them as you
would other windows and remain
pleasantly comfortable inside at all
times.
These units are available in clear,
colored or figured glass, we are told,
so that you can sit and enjoy the
view through regular windows if you
want to, or you can have complete
privacy and just the right amount
of light with the diffused type of
glass. They may also be used in
partitions if your office happens to
border an area which resembles the
open spaces and by using colored
glasses you can achieve some start
ling and attractive decorative et-
fects.
Mattresses Breathe.
II you have been around depart
ment stores or furniture shops lately
you have probably seen the new
lastex rubber mattresses which have
created such a stir of interest in re-
cent months. The advantages of
hoo.o h
vious and manifold but it was only
a matter of time before they had
to be improved upon.
Now a new mattress is on the
market which combines the beauties
of the accustomed inner-spring unit
with the new-found properties of
the rubber foam material. In this
way you are provided with the flex-
ibiity of the metal spring mattress
and its ability to support the body
as it thrasheS around at night, with
the soft padding effect of the sponge
rubber. The millions of tiny air
cells in the rubber also enable this
important layer to breathe" and
thereby keep the mattress fresh and
clean even after long use.
The rubber pad which is placed
over the usual layer of mattress
stufing is a full inch in thickness
and is provided with larger-sized air
pockets which give it additional
residence. The inner springs are, of
course, of the usual number and
construction and should stand up
under many years of sleeping.
Nails That Stay Put.
Have you heard about the new
nails with spiral shafts that drive
In like an ordinary nail but hold like
screw? These new fastenings
should find many places around
your house where they can be of
great service. Take that squeaky
place in the flooring which defies
your feeble attempts at silencing. A
few of these new nails driven in
with an ordinary hammer will hold
those boards down with never
chance of their perking up again.
