# Door Types By Operation ## Solid Laminated Door (Alpha) - Standard size 813 x 2032 thickness 42 mm. - Constructed from KD softwood and solid laminated core built up from 25 mm softwood strips crossbanded with 3 mm hardwood crossbanding and edged with 10 mm thick hardwood edges on stiles to match face veneer. - The crossbanded and edged "blank" is calibrated and the face veneer is applied over the edges to give the door a solid and uniform appearance. - Supplied with 2 concealed edges only and face veneer over edges. - Faces available: Veneer and plastic laminates. - Note: Not available in hardboard. - General: Used as internal door only. Mainly commercial and institutional use. - Mass ± 34 kg. ## Solid Laminated Exterior Door (Alpha) - Standard size 813 x 2032 thickness 42 mm. - Constructed from hardwood framing and solid laminated core built up from 25 mm softwood strips crossbanded with 3 mm hardwood crossbanding and finished with hardwood face veneer. - The solid laminated exterior door is supplied with exposed hardwood stiles only.
