Thermal Window Coverings

[CharlesHarris]

All good comments. My situation is similar to Mortblanc's and I have taken similar measures. House was originally a seasonal summer cottage which was closed up for the winter. It was originally built in 1976.

When reroofing I installed R50 fiberglas batting in the attic, and blew foam in the walls between the studs, plywood siding and interior wallboard. Sliding glass doors were walled in and insulated hollow-core steel doors hung, and a double-hung, double-pane window placed in the former opening, with the areaunder the window and around the door insulated to R25, and bookshelves built against the interior side of the newly walled-in area. Getting rid of three sliding glass patio doors not only inproved security, but also makes the place entirely livable in winter. Woodstove on lower level keeps house cozy in all but sub-zero weather.
