Tips for Getting the Most R-value Out of Insulation in a Tiny House
For Welss and her family, it was important to insulate the entire tiny house to make sure that the house was airtight with no drafts.
“It seems to be common practice to only insulate the roof, which helps to some extent,” she said. “But a house will only be really energy-efficient if it is fully insulated, airtight, has double-glazed windows, and is draft free.”
Having built quite a few tiny homes, Grotyohann and Schulz said proper insulation isn’t only related to the insulation itself, but how you build the walls that makes a significant difference as well.
“Minimizing wall framing minimizes thermal bridging and maximizes the space in your walls for insulation,” Grotyohann said.
She also recommends paying attention to how you seal the walls.
“Sealing all the wall penetrations around wires, plumbing, electrical boxes gives you a big return for very little investment of time or money, but is often overlooked by first-time builders.”
