Our home has plaster walls and ceilings. We have several questions and concerns:
1) Can you install batts of installation (not with the Kraft paper, but with the poly vapor barrier facing down) on the knob & tube wiring which is everywhere in the attic?
2) Is it necessary or a concern to replace the knob & tube wiring throughout the home?
3) The home is 1,346 sqft with 8 rooms, 3 bdrms, and 2 bathrooms - what is the range to have it replaced and an additional outlet added to each room? I would not want to bother electrician's for estimates if it is way out there.
4) We just received an estimate for a Trane XL1400 Super Efficiency Air Conditioner and a XL90 Forced Air heater unit since we currently have a wall heater with lousy efficiency. Is it a problem to have the venting in the attic where the insulation is and where the knob & tube wiring is?
Any recommendations or suggestions?
