Window Insulation for 100 year old glass
 

A friend of my mine owns a century old victorian that still has much of the
original glass. The glass has actually sagged so the bottom is thicker than
the top. She feels that the they have historical value and doesn't want to
tamper too much with the house as it is worth about 900k. Any suggestions
*other* than cheap plastic to improve the insulation window performance?


Thanks in advance.

How about "expensive" plastic?

Make removable inside storms using plexiglass.
Another notch up and get real glass insiders.

TOH show had a company that installs new jams that seal around and
lock more securely.

Exterior storms although inconvenient were used in historic district

While a common belief, it's almost certainly not true that the
thickness difference at the bottom is owing to glass "sagging" from
age...see the following

That piece of trivia aside, I commend the thought of not desecrating a
possibly historic house both from the possible financial ramifications
but moreso even from the simply "it's the right thing" to do
standpoint.

I'd investigate what is apropos for the specific area and house and go
that route. As someone else noted, external storms are certainly not
unheard of. If the house is in a conservation district, they
undoubtedly have guidelines -- if not, restricted, even so it is
likely they will be happy to point you in reasonable directions.

Another spot to read about 'glass flow' is the urban legends
newsgroup- alt.folklore.urban
It's in their FAQ-

She can buy expensive plastic. In the 70's, when oil was
expensive, there were a million businesses that installed 'inside
storms' - basically a plastic/lexan with magnetic edges which stuck to
the thin magnets they installed on the inside. It gave an invisible
third pane that went up and down easily, and stored easily.

There must still be some of these businesses around. [and if there
aren't, it isn't brain surgery to do it yourself]
