The load of approximately 250 kg per m 2 of a sod roof is an advantage because it helps to compress the logs and make the walls more draught-proof. In winter the total load may well increase to 400 or 500 kg per m 2 because of snow. [1] Sod is also a reasonably efficient insulator in a cold climate.
Medieval wheat grew to almost 6 feet (1.8 m) tall in very poor soils and produced durable straw for the roof and grain for baking bread. [citation needed] Technological change in the farming industry significantly affected the popularity of thatching. The availability of good quality thatching straw declined in England after the introduction of ...
The height of the ribs and beams should be 1 ⁄ 25 of the span between columns. [3] The width of the solid area around the column should be 1 ⁄ 8 of the span between columns. Its height should be the same as the ribs. [3] Diagram showing waffle slab rib and Beam Heights rule of thumb formulas.
Interior loadbearing walls are framed in the same way as exterior walls. Studs are usually 1 + 1 ⁄ 2 in × 3 + 1 ⁄ 2 in (38 mm × 89 mm) lumber spaced at 16 in (410 mm) on center. This spacing may be changed to 12 or 24 in (300 or 610 mm) depending on the loads supported and the type and thickness of the wall finish used.
The farmer would use a plow to cut the sod into bricks 1 by 2 feet (0.30 by 0.61 m), which were then piled up to form the walls. [59] The sod strips were piled grass-side down, staggered in the same way as brickwork, in three side-by-side rows, resulting in a wall over 3 feet (0.91 m) thick. The sod wall was built around door and window frames ...
