REVOLVING DOORS SAVE YOU MONEY
ON HIGH HEATING COSTS
Every time one person moves through a swing
door entrance (single, or vestibule type) an average of 1800 cubic feet
of cold, unheated air also comes in through the doors. When a person enters
through a revolving Door entrance an average of only 26 cubic feet of air
is admitted through. In some cases, the ratio is as much as 100 to 1!
This means a savings to you up to 25% in heating costs alone!

Cleaner Building
|
REVOLVING DOORS HELP KEEP YOUR
BUILDING INTERIOR CLEAN LONGER
How much does it cost you every time you redecorate
your walls and corridors? Only you know exactly what the elimination of
dirt and dust will save you you redecorating costs. Revolving doors mean
money in the bank - they keep out the dirt, soot, dust and grime that mean
cleaning and painting more often.

Lower Maintenance Costs
|
REVOLVING DOORS MINIMIZE ENTRANCE
MAINTENANCE COSTS
Revolving doors are in perfect balance - and
not subject to excessive pressure and leverage. They have a minimum of
moving parts to wear - so revolving door entrance maintenance is low in
cost and effort. Only regular lubrication, plus an annual check for wear
of air lock strips is required for years of carefree dependable service.
Customer records indicate that revolving door maintenance costs one-fifth
as much as swing doors.

Less Breakdowns
|
REVOLVING DOORS ELIMINATE COSTLY
ENTRANCE BREAKDOWNS
Any time an entrance needs to be closed because
of entrance failure every tenant is penalized. Because of the basic design
of revolving doors they eliminate emergency maintenance and repairs. All
service work can be performed outside of office hours. Emergency repairs
are relatively unknown.

Easy to Open!
|
REVOLVING DOORS TURN WITH A
TOUCH
Regardless of outside conditions - no matter
how hard the winds are blowing - revolving doors are always easy to turn
. . . with but a few ounces of pressure. Revolving doors are perfectly
balanced around the center pivot for easiest motion. . . since they are
always open - yet always closed - they are not affected by stack draft
as are swing doors.

Modern & Efficient
|
REVOLVING DOORS CONTROL TRAFFIC
IN AND OUT OF YOUR ENTRANCES
Traffic jams at your entrances cost you money,
too. Tenants - and their employees - who can't get in and out are unhappy!
Revolving doors are efficient doormen - they permit an orderly flow of
traflic letting more people in and out through any single entrance in an
hour than any other type of door. Properly engineered revolving door entrances
are planned to handle peak capacity times, like first thing in the morning, and for
noon, and evening one-way or two-way pedestrian traffic flow times.

More Available Space
|
REVOLVING DOORS LET YOU USE
ALL OF YOUR
LOBBY SPACE - RIGHT UP TO THE ENTRANCE
With a revolving door entrance you can use
all of your floor space, especially that profitable area at the entrance.
Because revolving doors transfer only a minimum amount of air each time
the door is turned. The space right up to the door is comfortable, along
with dust and draft free - high revenue floor space! In buildings where
service concessions are part of the income plan - these profitable, high-rent
tenants find that this added comfort at the entrance area means additional
revenue for them and the building owner.

Chic Appearance!
|
REVOLVING DOORS ARE MODERN IN
APPEARANCE
Revolving doors are more than just entrances.
They personify your building - they say "come in." The modem design of
the new revolving doors in sleek all-glass models - in streamlined stainless
steel - in beautifully fashioned wood - in rich bronze and aIuminum - adds
prestige to any building - creating that all-important favorable first
impression.

Less Air Conditioning
|
REVOLVING DOORS SLASH COOLING
COSTS
For the same reason that revolving doors reduce
heating costs, they also cut the cost of cooling in the summer. They cut
to a minimum the amount of air that can escape through the entrances to
keep the cooled air inside the building. As a consequence revolving doors
cut down the initial cost of air conditioning installation by permitting
the use of lower tonnage, less expensive equipment ... in daily use the
operating cost of the lower tonnage unit is less - and the maintenance,
cost is held to a minimum.
Revolving doors prevent overloading of
air conditioning equipment during extremely hot days - eliminating the
common cause of air conditioning failures.

Less Wind & Noise
|
REVOLVING DOORS ELIMINATE DRAFTY
LOBBIES AND CORRIDORS
The next cold morning, try the "shirt sleeve"
test - see whether or not you need revolving doors. If you can comfortably
stand in your shirt sleeves in front of your swing door entrance without
feeling the cold, you do not need a revolving door!
Revolving
doors are always open to customers and tenants - always closed against
drafts. Your tenants will appreciate the new comfort of your lobby and
corridors with a revolving door. Heavy duty blower fans - with their constant
noise - are not necessary when revolving doors are used.
