Insulating Tiny Home Kitchen And Bathroom

Thursday I insulated the kitchen and bathroom area in preparation for a major work weekend on the tiny home. I had guests coming over to help out on construction of my tiny house on wheels.

I put Rockwool insulation in the bottom 4 feet of wall cavity. This is supposed to be mouse and insect resistant, mold and water resistant. It works even when wet. I figured putting the more expensive insulation in the lower 4 feet of wall space will protect my home if anything does penetrate into the walls. Mice and insects will be trapped in that particular wall cavity. With no holes in the wall studs there is no way for anything to travel between the studs into another wall cavity.

The mineral wool insulation also works even when wet so if there is ever a water leak in the walls or windows, the rockwool will continue to do its job and it will not mold.

The rest of the walls up to the ceiling are being filled with formaldehyde free fiberglass insulation due to its lower cost.

It is a slow process insulating the walls because Lowes did not have 24 on center insulation so I got 16 on center, which means a lot of cutting.

I started to put in furring strips to put on the radiant barrier foil. The radiant barrier blocks heat from leaving the house in winter and heat from entering in summer. It is a double sided bubble wrap which also adds about 5 R of insulation factor with the air gaps on both sides. The manufacturer claims up to R 30 if properly installed into the wall cavity with enough space on both sides.

Either way, this little house on wheels is going to be toasty warm this winter.
