Q. I dwell in an 1860s farmhouse. 1 hundred several years back, the attic was utilised as a bed room it has an opening for a wood stove. Proper now we have the opening to the stairs blocked with an insulated doorway. The attic roof is not insulated, but the floor is. My relatives has lived in the property for additional than 30 a long time. We use the attic only for storage on the other hand, with the prospect to operate from house and the addition of sons-in-regulation and grandchildren, it makes sense to use that house. There is area to stand up, and the centre ceiling is flat and slopes to the wall. It also has previous bead board everywhere. Will insulating the roof assist comprise heat in the winter season and minimize it in the summertime? Do I have to have to get worried about trapping in humidity? Any information about lowering hearth risk in an attic? We have a window at the two gable finishes and nominal electricity up there by now.

A. It is tough to say no matter if the ceiling height meets code: Below in Massachusetts, the minimal is 7 feet for living house. To reply your concern, you most definitely could include shut-cell icynene insulation in the rafter bays. This will support keep in warmth throughout the winter season months, and you would be surprised how perfectly it will work at retaining out the heat in the summer months. Shut mobile will not develop moisture issues, as it is proficiently a vapor barrier. If there are knee walls in the attic (exactly where the roof satisfies a vertical wall), people should really be insulated as effectively. Your gable home windows could be single pane, so you should take into consideration changing them or introducing a excellent storm window about them.
Healed closed-cell insulation does not create a fire hazard, as well as you would be covering surfaces with wallboard (the gypsum inside is fireplace-resistant). I would extend any difficult-wired smoke and carbon monoxide detectors into the attic or set up at least a battery device if your home is not hard-wired.
Q. Can a 200-amp support assistance 4 one particular-bed room models with electric powered warmth and four electric stoves, fridges, TVs, and so on.? If certainly, what about four new electrical incredibly hot h2o tanks (gas or electric)?
A. Potentially — if you have a gasoline very hot water heater for every single unit. I would assume you are conversing about an on-demand scorching drinking water heater. All methods are diverse (dimensions/capacity), but there are kinds that would scarcely healthy less than the 200-amp umbrella. Just one opportunity monkey wrench: If this is a four-family members, then by code you need to have a community meter for exterior lights/electric power etcetera. That could be 15 amps right there. By my calculations, including electric powered very hot h2o heaters pushes you to at least 280 amps.
