#704: Groundwater, Radiant Barriers, Water Management with Masonry Walls

Acoustical panels, like wood wool, can effectively deaden sound in large, hard-surfaced rooms, even those with very high ceilings.

When building in flood zones, elevating the first floor significantly (e.g., 13 ft) on masonry piers and utilizing engineered floor systems can mitigate future damage.

Floor trusses offer clear spans and easy routing of utilities, but can be more expensive, take longer to get, and are not trimmable.

Radiant barriers are most effective in hot climates, but thicker insulation layers often offer a better return on investment than standalone radiant barriers.

For new construction, sheathing with an integrated radiant barrier is cost-effective as it requires no additional labor and its performance is less affected by dust buildup.

When renovating historic masonry homes, insulating the interior walls can lead to moisture issues like joist rot; exterior insulation (if acceptable aesthetically) or focusing on air sealing and basement moisture management are safer alternatives.

Consider an energy audit and address low-hanging fruit like air leaks and window gaskets in old homes before undertaking drastic insulation measures that could compromise the structure's integrity or historic appeal.
