Spence Flush Honeycomb Doors can be used internally or externally. Doors have lock blocks on both sides to allow hanging from either side, and feature extra wide top rails for strength and versatility. Internal frames are KD (Kiln dried) Hardwood, Finger Jointed Pine or MDF (Medium Density Fibreboard).

These doors incorporate Formcell Honeycomb, a cellular cardboard reinforcing mesh which is extremely light and has tremendous structural strength.
