UNIT- 
WINDOW 
I he Lunken Unit-Window is “something new,” but so com¬ 
pletely developed that every requisite in window construction 
that you have so often and so long desired is there to meet your 
most ambitious expectations. 
With it you may use the entire window area for ventilation in 
Summer, at the same time screening the window from top to 
bottom. 
All that the builder has to do is to set the Lunken Unit- 
Windows in the window openings of the new building, 
apply the plaster, trim and finish, and the windows are 
ready for use. 
When it comes 
time to put away 
the flv-screens for 
the Winter, you 
simplv push them 
up out of the way, 
securing them 
snug and warm 
and dry until they 
are needed again, 
when they are 
ready, instantly. 
In zero weather, 
scientific weather¬ 
stripping bars out the cold blast and keeps in the house the 
warm air needed for health and comfort. 
The Lunken Unit-Window comes completely assembled, its 
frame forming the shipping case. The window sash and 
fly-screens are securely held in the box. The sash-cord 
is in place over the sash pulleys. The sash weights are 
held against damage. The weather-stripping and sill are 
all protected 
Top, bottom or center ventilation may be secured by locking 
the windows with safety catch in the appropriate position. 
Cleaning the windows is made easier than ever before. No more reach¬ 
ing and straining; no more sitting on the window sill; no more exposure 
to health, nerves and limbs. 
Just think of it, Mr. and Mrs. Home-Builder—100 per cent ventilation 
in Summer, no air leakage in Winter; no more taking down, storing and 
putting up of fly-screens ; no deterioration ; no repairing; no more discom¬ 
fort and danger in cleaning. An incomparably better window for your 
home. 
There’s a great deal more about Lunken Unit-Windows 
you ought to know. Ask your architect, or if you want to 
post yourself, our catalog will be sent, gladly, for the asking.
