How to insulate a stone house with plaster walls (240 year old Dutch Colonial)
MJZ

I live in a pre-revolutionary Dutch Colonial. The main floor walls are 18" deep sandstone with plaster interior (over animal hair, and random old newspaper). The sandstone has great thermal mass so that the house is impervious to sudden temperature changes. However, from December to mid April it becomes an icebox, as the stone adapts to the outside temps.

Anyone have any ideas that won't impact the character of the house? Keeping warm without changing the character is really the challenge. I appreciate your thoughts and responses.

Regards,

MJZ

You can use an adhesive to glue foam boards/panels to the interior side or use a foam system like insofast, insofast.com. You are going to lose a couple inches of interior space.

You should research info reguarding what you can do to the existing structure.
Check with the nearest Historical Society and ask what recommendations they may have that will not degrade the structure.
Also check on what tax credits may available.
Research Thechnical Preservation Services.
Don't do anything without a lot of research.
