Foam Wood Rafter Head
Polure foam wood rafter heads add architectural depth, timber tail accents, and craftsman character under exterior roof eaves without the structural weight or maintenance of real wood beams. Molded from genuine wood logs using high-density rigid polyurethane (150-220 kg/m³), these rafter heads replicate natural grain patterns while offering wood-like durability at an ultra-lightweight mass. Formulated with a closed-cell matrix, water absorption is strictly under 1%, ensuring the rafter heads will never rot, warp, split, or harbor wood-boring insects under outdoor roof exposure (-100 °C / +80 °C). Classified under fire class B2, each piece is delivered pre-treated with a white acrylic primer. Installation is executed using continuous polyurethane assembly adhesive on rear surfaces paired with mechanical countersunk screws. Fill screw holes with facade putty and finish with elastic UV-resistant exterior paint.
