building the parapet |
|
|
|
Parapets are used in traditional adobe construction to enclose and shroud the roofline. Parapets also serve to "anchor" or provide weight to hold down the roof structure securely in strong winds. They also can serve as a wind break and "shelter" the roof/flashing junction from strong winds. For our cob studio the parapets are simply an extension of the cob wall above the roofline. Our parapets as in "traditional" adobe construction help to protect the roof from the elements and also provide a "facade" that will shroud the surface of our metal roofing from view. We had warm weather the past three days (Dec 18,19,20) which enabled us to mix cob and build up the parapets. The temperature during the day was about 50F. Cob mixing was easy as we just let the sun melt the snow which in turn saturated the dirt for our cob. |

Kristina hammers nails into exposed beam. The nails will help to secure the cob to the wood. |

Kristina still hammering away! |

Kristina covers the cans with cob. |

For the north-facing parapets we embedded cans to fill the bulk and help to increase insulative capacity. |

After installing insulation the large gaps were first plugged with dirt-filled bags. |

|
With the north and south facing parapets completed we saved the east for last so we could fill with insulation before enclosing it. |

South-facing parapet built up to roofline. We will build parapets a little higher when the weather gets warmer in the spring. |

Earthbags were then covered with cob. |
