Straw Doors. Masonite says its new Safe 'N Sound Interior Doors are milled from a low-density fiberboard (called DorCor) that uses renewable wheat straw as its primary raw material. The units contain only low-emission adhesives and sealants and no urea-formaldehyde, the company says. Though lighter than conventional particleboard panels, they are billed as more effective sound-deadeners. A stock-size door panel costs about $65; special-order sizes go for about $90.
