Rustic Polyurethane Rafter End
Polure rustic polyurethane rafter ends provide authentic craftsman detailing under exterior roof eaves and for interior exposed beam ceilings. Precision-molded from real weathered wood cuts using high-density rigid polyurethane (150-220 kg/m³), these rafter ends replicate deep rustic wood grain and hand-carved chamfers while remaining light enough for safe overhead installation by a single person. Featuring a closed-cell matrix with water absorption under 1%, they are entirely immune to moisture rot, warping, or wood-boring insects across extreme temperatures from -100 °C / +80 °C. Classified under fire safety class B2, each piece is delivered pre-treated with a factory white acrylic primer. Installation is completed using a continuous bead of polyurethane assembly adhesive on contact faces combined with mechanical countersunk screws. Fill screw holes with acrylic or facade putty and sand smooth prior to applying exterior UV-resistant or interior wood-tone paint.
