Affect daylighting schemes

[akterchumma699]

The cycling of temperatures and the migration of moisture from one day or season to the next can manifest at windows in the form of:

shrunken gaskets and seals;
warped, faded, or displaced frames; and
etched or fogged glass.
As glazing becomes scratched, distorted, or clouded, building occupants may complain of compromised views, along with bothersome glare that can .

Another factor to consider is maintenance and cost control. As windows age, it may become increasingly difficult and cost-prohibitive to find replacement parts. Keeping up with the needs of older windows is more rcs data demanding, as maintenance personnel spend hours responding to user complaints. (While windows have generally become more thermally efficient, increased maintenance efforts over time are generally the result of deterioration and failure of window components [e.g. gaskets, seals, and hardware] rather than shortcomings in the original design.
