Temperatures vary widely in Utah throughout the year—or even throughout the day if you live at higher elevations. Investing in high quality insulation will go a long way. The better insulated your tiny home, the less the competition between inside and outside temperatures. This means you can keep your Utah tiny home at a comfortable temperature year-round with maximum energy efficiency. All of our homes at Wind River are constructed with 2×4 framing and spray foam insulation. Spray foam has by far the highest R-value available for the tiny home application, and wooden construction allows less air infiltration than steel framing. Additionally, we use LP SmartSide for a low-maintenance and durable siding that won’t warp or change with fluctuating temperatures (and which we can do in any custom color(s) you like). Speaking of your exterior color palette, for hotter climates, we recommend keeping it light and choosing a galvalume metal roof that reflects the heat from the sun.
