Hemlock has an exceptional ability to tolerate the high measures of stress, strain and loads required of each component. For the homeowner, Hemlock and Douglas Fir qualities of strength and appearance ensure their home is both strong and very beautiful.
Why Douglas Fir and Hemlock for Zairai homes?
- Can take the weight. Compression parallel to grain is a measure of a piece of wood's ability to resist a crushing force that is applied to the ends of a piece of lumber. In-grade tests prove Hemlock can carry the load making it an excellent choice for Hashira and other Zairai components such as Mabashira.
- Superior fastening strength. Fastening strength is crucial to structural integrity. Studies prove that Hemlock holds nails and screws better than most other species.
- Douglas Fir and Hemlock are stiff woods. Modulus of Elasticity (Stiffness) is the measure of how much the lumber will bend when weight is put on it. This is an important requirement for Hashira applications to prevent buckling. Japanese builders can use Douglas Fir and Hemlock with confidence.
- Douglas Fir and Hemlock is hard to break. Modulus of Rupture (Bending Strength) is the measure of stress that you can put on a piece of lumber before it breaks. Douglas Fir and Hemlock brings this characteristic to Moya and Keta components.
- Strength to span. The inherent strength of Douglas Fir and Hemlock also means that builders can now safely and with confidence design and build houses with wider ceiling spans and larger rooms in keeping with modern lifestyles.
- Douglas Fir and Hemlock can resist a crushing force Compression perpendicular to grain is a measure of a piece of wood's ability to resist a crushing force applied to its face. High resistance to this type of compression makes Douglas Fir and Hemlock ideal for Dodai and other Zairai components such as Neda,Moya and Keta.
