I cannot believe it’s been so long between posts, but it’s not for lack of forward momentum!  Trailer construction is finally underway.  It was a little more expensive than planned, but still within budget.  I will pick it up before Christmas!  It looks like construction can come together pretty quickly; I have decided to utilize SIP technology.

Structural Insulated Panels (SIPs) are made from all recycled materials (green building).  They are either aluminum or composite wood inner and outer shells filled with solid foam insulation.  They replace all framing and roll insulation and interior and exterior plywood.  They fit together like a gingerbread house, you can even use them for roofing panels.  Then you apply whatever interior and exterior treatments you were going to use with traditional framing.

SIPs are much more road-worthy than traditional framing, and about 50% lighter.  There are a couple of tiny house bloggers who have already built their places with SIPs, plus I met a local RV manufacturer that builds their own SIPs and is getting into the tiny house market.  Another bonus is you can order your panels with or without window cuts and cut holes yourself.

So the trailer will be in my backyard within 2 weeks.  Next step is ordering (and paying for) the SIPs, but the “ebay getting rid of stuff” is still moving along briskly, so I anticipate ordering those shortly after the new year.  In my next post, I will be updating my “wish list” of building supplies, based on what I already have and taking out all the framing needs.
