輕鋼結構 ICF construction- the best energy efficiency home

非常好， 節能， 鋼筋水泥造的， 通常不會壞。 zero maintenance so far for me.   My home is built this way.  The energy efficency is far superior than typical stick-built home.  The wall has steel enforced concrete wall with foam insulations on both sides.  I expect the home will last much longer than the normal construction home.
