Solution found to Condensation and Maintenance Problems

Very sensitive art restoration is

performed in the 1975 addition to the

Allen Memorial Art Museum, located on

the campus of Oberlin College in

Oberlin, Ohio. In addition to the

restoration work, the building also

houses pieces from the Colleges

collection not currently on display.

Interior humidity levels are maintained

from 40% to 50% to prevent sensitive

artwork from deteriorating. While these

levels are very high relative to the

conditions encountered in conventional

buildings, they are typical in museums.

Soon after this addition was completed

using conventional double glazed

windows, the College began

experiencing problems of condensation,

moisture build up and mildew on interior

surfaces.

Robert H. Fuller & Associates Inc. of

Columbus, Ohio, were retained by the

College as engineering and architectural

consultants to implement a window

replacement program. They determined

that they would need windows having a

CRF factor in excess of 70 to eliminate

the condensation problems. A complete

thermal analysis of Visionwall

Corporation’s M20 window system was

conducted to verify that the use of high

performance windows would

permanently solve the problem. It was

also necessary to include a detailed

analysis of the window details in the

existing wall structure to ensure integrity

of the envelope.

The project presented other

challenges in addition to solving the

condensation issues. It was

necessary to maintain the design

features of the original facade of this

well known building designed by an

internationally renowned architect.

Visionwall’s engineering department

designed special extrusions to

develop the five (5) inch intermediate

vertical mullion (Figure 1).

With analysis complete and budgets

approved, window installation on

phase I began in May of 1996, and

was completed in time for occupancy

for September, 1996. With all of

phase II and phase III in place, the

ability of VISIONWALL system to

provide a solution to the condensation

problem is now documented.

According to Gene Matthews, Director

of Facilities for the College, “

The College’s satisfaction with the

VISIONWALL high performance

window system is such that they

recommended use of the product on

other projects.
