Tiny Home Wall Thickness

So you really need to think about wall thickness in a tiny house. In general, when using standard 2×4 inch wood, external walls will be a little over 5" thick (or more if you use fairly bulky exterior siding) and interior walls will have a thickness of around 4½" (due to the drywall on both sides). As someone currently building their tiny home, I'd go with the drywall.

A 4' x 8' sheet of 1/2" drywall is less than $10. An 8' by 6" piece of shiplap is $10. For an equivalent surface area, shiplap is 8x more expensive.

These prices are based on what I paid at Home Depot in TX. Discover the significance of wall thickness and insulation in tiny houses to ensure comfort, space efficiency, and energy savings.

Key Factors Affecting Exterior Wall Thickness Climate conditions: In cold regions, thicker walls with added insulation (e.g., 30-40 cm / 12-16 inches) help improve energy efficiency. Energy efficiency: Passive houses and energy-efficient homes require increased insulation layers, which can add 5-15 cm (2-6 inches) to the total thickness.

In a nutshell: less wood means less thermal bridging and more space for insulation and the addition of 1" of continuous insulation results in a wall assembly equal in thickness to that of a 2×4 wall but with better thermal performance because of reduced thermal bridging.
