I-NF-D / SM Interior non-fire & Smoke double acting doorset, single or pair

Designed for installations requiring a door that opens both ways, this versatile interior double acting door set is manufactured with a solid composite timber core and an integral MDF face layer (S-CORE). Unless you request a special finish, this door will be supplied sealer coated on both faces, as well as top and bottom, ready for priming and painting. For applications where the door has to match other architectural features, we can apply a specified veneer or overlay (laminate, vinyl or steel) to the faces. Inlay panels or planted detail can also be affixed on request, to suit heritage buildings.  This is a hung door, which means it is supplied as a complete fire door set - door leaf and door jamb, with or without hardware.
