With the log house and timber frame in place, the construction at Bunny Vista continues with a different focus.
This week we are looking forward to the arrival of the structural insulated roofing panels (SIPs). SIPs have a layer of insulation sandwiched between two layers of structural sheathing. SIPs are often used with timber frame construction or in place of conventional stick construction. They are strong and weather-resistant and can be used for roofs, walls, and foundations. They are compliant with many “green” building programs, because their production has minimal environmental impact and because they are very energy efficient.
We are buying the SIPs for Bunny Vista from R-Control, which has a manufacturing facility in Winchester. There have been some delays with the SIPs, which were scheduled to arrive as soon as the timber frame was raised. After many conversations with the manufacturer and the distributor, Kelley went to Winchester with Aaron last week to pick up the panels, only to find that they had not been manufactured to the specifications Jordan had provided. The distributor has promised to deliver the panels on Wednesday, and Jordan will arrive on Thursday to install the SIPs, after which we will all breathe more easily. In the meantime, the timber frame is wearing a giant sheet of plastic to protect the cypress ceiling from the weather.
Lewis has finished applying the base layer of the chinking to the exterior logs; the base layer is a traditional mortar over lath on wide openings and Grip-Stick foam on narrow openings. This prepares the log walls for the Perma-Chink. Kelley has been choosing the stain color and the Perma-Chink color.
On Monday, Eric Thompson of Earthstar Systems in Waynesboro will arrive to lay out the mechanical room and figure out the tubing arrangement for the radiant floor heating on the first floor. He will also lay out the trenches for the geothermal heating and cooling system. Sometime this week we will dig two 300-foot trenches, five or six feet deep, which will each have three rows of one inch tubing.
Kelley is also getting ready to place the order for windows and doors. Although he plans to make most of the doors for the house, we will buy the doors leading to the porches of the timber frame.
