I was thinking about my posts regarding the Santa Claus Haus and how in depth I wanted to be with them. When this blog first started we were one of only a handful of builders, documenting the day in and day out of a tiny house build. We talked about everything from screws and bolts and how to drill pilot holes to how we felt spending money on each part of the build. We covered our frustrations and our victories. But this build it so different. Years have passed and the Internet has become saturated with tiny house “How To” information. That said, I decided really just to give shorts updates to let you know how the Santa Claus Haus was taking shape and what building for fun was like. So here we go. Santa Claus Haus: Subfloor.
Today we took our finished salvage trailer and put on the sheet metal and subfloor. It was pretty standard. We used 4′ x 8′ sheets of galvanized metal my brother-in-law supplied for us (he is an HVAC technician), fastened to the top side of the trailer using self-tapping, stainless steel screws every 24″ or so.
Once the metal was in place we filled the frame cavities with R13, paper backed, fiberglass-free, insulation batting. In our original tiny house we used a wonderful, recycled denim insulation made by DOW products. Unfortunately, that product has long been discontinued. That, couple with our very small budget, meant ‘pink panther’ insulation for us. We especially didn’t care too much because we aren’t going to live full-time in the SCH so we aren’t truly worried about a number of issues we were in 2010.
After the insulation was in we added a subfloor of 7/16″ OSB. The size of the SCH required only 2.5 sheets of 4′ x 8′, so we did well on budget and took all of 12 minutes or so to fasten down.
