Red Deal  is a true Scandinavian Pine also known as Scots  Pine  (Pinus Sylvesrtis) and has both warmth and strength. Being tongued and grooved  this flooring can be nailed to  joists just  like traditional  floorboards and being solid  wood it can be sanded  / oiled /varnished again and again  so  its a  great choice for a natural and sustainable wood floor
