A four-panel bifold door for a restaurant in the East Village, at 107 1st Avenue in Manhattan. The restaurant has a brick-walled patio behind the dining room, and the opening between the two had to work both ways: fold fully open in good weather so the dining room and the patio become one space, and close into a tight, insulated wall when the patio is out of use. We supplied and installed the door in black thermally broken aluminum with energy-efficient glass.
A restaurant door gets opened and closed all day, and in a city dining room the comfort of the tables nearest the door depends on how well that door seals. The profile here is thermally broken: a polyamide strip separates the inside and outside halves of the aluminum, so the cold of a January evening is not carried straight through the frame to the inside face, and the frame does not sweat or chill the air around it. Combined with energy-efficient insulated glass, the door keeps the room warm on cold winter days and keeps the heat out on hot summer days, with less load on the restaurant's heating and air conditioning. The black finish matches the dark woodwork of the interior and the industrial character of the patio.
The door is four full-height panels on a top-hung track, folding to one side to leave the opening clear. Each panel is a narrow black frame around a single large lite, so the view of the planted brick wall is almost uninterrupted when the door is closed. The unit sits on a stone threshold at floor level, under the existing steel lintel and roller-shutter housing, and is sealed to the brick jambs on the patio side. Inside, the dark wood paneling returns to the frame and the patterned floor runs up to the sill. The result is a dining room that opens onto its patio in seconds and closes into a quiet, insulated wall when it needs to.
