Q. I stay in an 1860s farmhouse. A person hundred several years ago, the attic was utilized as a bed room it has an opening for a wooden stove. Correct now we have the opening to the stairs blocked with an insulated doorway. The attic roof is not insulated, but the flooring is. My loved ones has lived in the house for much more than 30 years. We use the attic only for storage nevertheless, with the opportunity to operate from house and the addition of sons-in-regulation and grandchildren, it will make sense to use that area. There is space to stand up, and the center ceiling is flat and slopes to the wall. It also has aged bead board just about everywhere. Will insulating the roof support contain warmth in the wintertime and cut down it in the summer? Do I will need to worry about trapping in dampness? Any information about minimizing hearth danger in an attic? We have a window at the two gable ends and minimal energy up there presently.

A. It is really hard to say no matter whether the ceiling top satisfies code: Here in Massachusetts, the minimum amount is 7 ft for dwelling room. To solution your dilemma, you most definitely could add shut-cell icynene insulation in the rafter bays. This will help keep in heat during the winter months, and you would be shocked how very well it will work at maintaining out the warmth in the summer. Closed cell will not produce humidity challenges, as it is correctly a vapor barrier. If there are knee partitions in the attic (where by the roof satisfies a vertical wall), all those need to be insulated as very well. Your gable home windows might be one pane, so you ought to take into consideration changing them or including a high-quality storm window above them.

Treated closed-cell insulation does not make a fire hazard, as well as you would be covering surfaces with wallboard (the gypsum inside of is fire-resistant). I would lengthen any tricky-wired smoke and carbon monoxide detectors into the attic or install at minimum a battery device if your residence is not hard-wired.

Q. Can a 200-amp company aid four a single-bed room units with electrical heat and four electric stoves, fridges, TVs, and many others.? If sure, what about 4 new electric powered incredibly hot drinking water tanks (gas or electrical)?

A. Probably — if you have a gas warm drinking water heater for each individual device. I would assume you are chatting about an on-desire warm water heater. All methods are distinctive (sizing/capability), but there are kinds that would hardly fit less than the 200-amp umbrella. Just one potential monkey wrench: If this is a 4-spouse and children, then by code you require a public meter for exterior lights/electricity and so on. That could be 15 amps ideal there. By my calculations, including electrical incredibly hot water heaters pushes you to at minimum 280 amps.
