Your solarium, your way. HalfPhab's go beyond traditional solarium, and include Earth tubes to maximize solar powered HVAC potential.
HalfPhabs are solariums with solar passive systems built into them. This includes earth tubes, and can connect to an existing HRV or forced air systems to bring those benefits into every room of your home.
When zoning and space restrictions limit full Sophab installations, HalfPhabs can provide many of the same benefits, serving as extended living space and solar collection.
