Healthy Homes for Rhode Island — Bay Salt, Mill Housing, Urban Air
Virtual Home Health Score assessments statewide. GaiaCrete™ detailed for Rhode Island's maritime humidity and aging mill-era walls. Founding Mr Hemp House® dealer territories open by ZIP code.
Bay salt aerosol
Narragansett Bay salt reaches most Rhode Island neighborhoods, corroding fasteners and flashing and keeping cladding damp longer than inland walls.
Mill-era housing age
Rhode Island's triple-deckers and mill housing were built without air barriers, so retrofit insulation frequently creates condensing surfaces.
Urban corridor air quality
Homes along the I-95 corridor through Providence take in traffic-related particulate whenever the envelope leaks or ventilation is unfiltered.
What Climate Zone 5A Means for Rhode Island Homes
Rhode Island is small, coastal, and old: nearly the whole state sits within reach of Narragansett Bay's salt air, and its housing median age is among the highest in the nation. Zone 5A winters and muggy bay summers act on the same mill-era walls. Dense Providence and Pawtucket neighborhoods add urban air-quality load on top of that.
Rhode Island State Building Code (SBC-8 Energy Conservation)
Rhode Island adopts the IECC statewide through SBC-8 with state amendments.
