DURATION Moulding and Millwork grew out of a simple need back in 2012... a responsive supply source for moulding and millwork products that would complement existing BORAL poly-ash composite trim and siding products. Early experimentation with milling and laminating techniques led to refined practices, specialized machinery and equipment, and an overall commitment to quality and consistency that resulted in DURATION being acknowledged as a registered trademark for poly-ash millwork in 2017.
