| PROLONG THE LIFE |
| Chinese unification forestry teaching material "Lumber Protection Study" explicitly indicate that, the life-span of people who live in log made houses is 9 to 11 years longer than people who live in ferroconcrete made houses.It is obvious that log living environment has supernatural effect to human being's health. |
| BIOLOGICAL ADJUSTMENT FUNCTION |
| Newly built log house has log's faint scent,what volatilizes from log is a kide of extract oil.This extract oil has the ability of deodorization,killing bugs,preventing moldy and sterilization.It can clean air,make people feel comfortable,clear up people's strain which effected by stress,level off pulse and remove tiredness. |
| GREAT HEAT PRESERVATION AND ECONOMIZE ON ENERGY |
| log house has great ability on heat preservation energy and economize on energy.Under the same thickness condition,log made house's heat insulationg value is 16 times than air brick made house.In summer,the temperature in log house is 2.4 degree lower than brick house;in winter is 4 degree higher.Log house is coller in summer and warmer in winter. |
| STRONG QUAKEPROOF CAPABILITY |
| Brick and stone made house can't eacape from collapsing in big earthquake.In contrast,log house always stand erect after the earthquake.Its lighter body absorbs less earthquake wave.In big earthquake,log house may change shape but will not fall apart,or it may be moved by the earthquake wave,even the whole building be moved out of the groundsill, the configuration still exist. |
| SHORT CONSTRUCTION PERIOD |
| All of the component and pontes of log house are standard production;therefore the speed of production and construction is faster than forroconcrete made house or brick house.Sine the log house is light;it will not require complex crane equipments in factory or in building sute and has a very fast construction system to build up. |
