The window
areas in the home by their nature have traditionally
been made from materials which aren’t as durable
as the brick structure that they are essentially
slotted into, and as such, rather like the moving
parts in a machine, they are prone to many different
types of problems.
Older
glass can become more brittle and slightly distorted,
and can be prone to cracking e.g. with the effects
of the cold and strong winds. This can create problems
with drafts and cold in the house, and the obvious
cost of replacing the glass.
If not
maintained properly and painted regularly, older
wooden window frames can rot and split and can again
leave the home more open to the effects of cold,
damp, and the elements.
