Q: We are currently having fiberglass insulation blown into our 1850s house. So far they have completed the attic and the second floor. They have drilled the holes in the first floor. Now they are telling us that they cannot find the rubber hose they need to complete the project and it is too cold for them to complete the project and we need to wait until spring. I would like to know if the cold weather is a factor and if you know what the rubber hose is called, which they claim they cannot find.
A: It depends somewhat on exactly what they are blowing into the cavities. Some wall-cavity insulation has a binder or an adhesive additive that might be affected by cold weather, but in my opinion that would be only during prolonged periods of extreme cold. As to the rubber hose they’re referring to, I would have no idea what that could be. Even the most specialized parts for insulation-blowing equipment should be readily available from the manufacturer, and I could see no reason why it should delay a project by several months.
