In Boston, zone 5A, in a 1100 ft^2 19th century condo.
We're turning a pantry into a second bathroom, a wetroom. The pantry is in a corner of the house that's currently pretty cold in the winter. Our home already has cellulose insulation, we spend only about $500/year on heating, and any large improvements would have to be coordinated with other condo owners, so I'm not sure we have much incentive to do a general energy retrofit.
My main question is, will local insulation improvements help with comfort in that room even if we don't improve the rest of the house? I've heard that highly insulated houses are more comfortable even at lower temperatures because the surface temperatures are higher, and I'm hoping that would hold true for a single room, too. I have to have the window replaced anyway (it being a wetroom, the window is considered part of the shower enclosure, so it needs tempered glass), so I was considering an Intus window, and I'm considering asking the contractor to put 1 inch of R-5 foam board behind the tile backer, if code permits.
Also, according to the Sunfrost concept shower page, it helps to have surfaces of low thermal mass material. Our current plan is tile; is there such a thing as low thermal mass tile?
