About this course:

The goals of historic preservation and energy efficiency and comfort often seem in conflict, as higher insulation levels can pose new risks to these timeless structures. Yet it need not be so. The classic brick wall is un-insulated and prone to air infiltration. As many historic buildings fall under some form of aesthetic scrutiny, often exterior insulation is prohibited. Therefore the only option to make these buildings energy efficient is to insulate them on the interior. This presentation takes a close look at how to insulate these walls safely from the interior – considering moisture drive, bulk rainwater issues, and insulation materials – avoiding the dangers of freeze-thaw and mold Ensuring that the integrity of the structure and making a more robust structure for the next 100 years is the goal!
