Tiny Refuge is now (temporarily) waterproof! The first part of insulating my tiny house is complete. There is now 1″ of insulation and house wrap on the walls and dormers and 2″ of insulation and ice & weather shield on the roof. So the roof is now ready for the metal roof and the only step left for before doing the siding is to waterproof the space between the bottom of the subfloor and the sheathing.
I am pretty excited about being ready to have the roof and siding on. Really excited. Part of that excitement stems front the fact that the tarp has seen better days and putting it up the tarp is something I am uncomfortable doing myself.
While putting up the insulation on the roof yesterday, Stefan and I discussed that the rafters could have simply be done with 2″x6″s instead of 2″x4″s as we have added 2 inches on the outside instead of the inside. It was a lot more work to add the insulation on the outside. It wasn’t just a matter of slapping down the insulation, Stefan cut down 2″x3″s (which measure 1 ½” x 2 ½”) so that they are the same height as the 2″ insulation and they were used as strapping so that the 4″ metal roof screws will have a wooden surface to be attached too.
We bought 2′ wide 2″ insulation with an Rvalue of 10. The strapping runs along the edges of the roof sections and then horizontally about every 2′ and then the ice & weather shield goes on overtop.
