This morning, a team of guys were putting up Sheetrock. They started yesterday, finishing most of the first floor. I knew it would really change the feeling of the rooms. Before the Sheetrock, they added a second layer of insulation that is a soft fiberglass-type batting. It really makes the house sound hushed. It's being added to all the exterior walls and the interior walls between the bedrooms and on the first floor between the bathroom and the living room to function as a sound barrier.
A bubble wrap-looking insulation for the radiant floor was also installed over the tubing attached beneath the subfloors. The tubes for the system where installed a couple of weeks ago, and the network of pipes were mounted to a control panel in the basement utility room. The boiler, which will heat the water in the system, is surprisingly small. It's not much bigger than a suitcase, and it includes the tankless hot water heater for the kitchen and bathrooms. It's a new system from Italy.
