731 Jefferson Avenue is a high performance, low cost, masonry retrofit. The design approach is to “gut” as little as possible, minimize the waste produced, and to use low VOC, natural non-petrochemical products. The technical open house is a chance to see the mechanicals and air sealing before the walls get closed up.
Here are some highlights:
• Wall insulation: Redstone PURA, a mineral-based capillary-open board
• Roof and cellar insulation: Roxul mineral wool
• Air sealing: pro clima Intello & DA, pro clima tapes
• Ventilation: Lunos ego and e2 “through wall” ventilation system
• Windows: Rieder unpainted Douglas fir frames treated with larch oil, triple pane
• Skylights: Lamilux FE
• HVAC: Mitsubishi mini splits/ducted
• Hot water heater: GE Geospring heat pump
Please join homeowners and designers, Bettina Johae and Daniel Herskowitz on Sunday, June 15 from 12 – 3pm. Harald Hefel of Amnova/Hefel Masonry will be present to answer questions about Redstone PURA mineral board.
731 Jefferson Avenue is located between Malcolm X Blvd and Patchen Avenue in the Bedford Stuyvesant neighborhood in Brooklyn. Nearest subway stops are the Utica Ave stop on the A/C train and the Gates Ave stop on the J train.
