Custom Door Jambs
Polure custom door jambs offer bespoke framing dimensions and tailored profile designs engineered for non-standard interior and exterior doorway surrounds. Manufactured from high-density rigid polyurethane (150-220 kg/m³) via custom CNC molding, these jambs replicate historic architectural profiles with wood-like durability while eliminating warping or shrinking. Featuring a closed-cell polymer structure with water absorption under 1%, they will never rot, swell, or cultivate mold in humid environments. Thermally stable between -100 °C / +80 °C with Class B2 fire resistance certification, every length arrives pre-coated with factory white acrylic primer. Installation onto doorway surrounds requires applying a continuous bead of polyurethane assembly adhesive on rear contact faces and miter joints (silicone is strictly forbidden), combined with countersunk mechanical screws. Fill screw recesses and joint lines with acrylic putty, sand smooth with 180-220 grit paper, and finish with two coats of paint.
