Decorative Mantel Frame
Polure decorative mantel frames offer a classic focal architectural trim for interior fireplaces and wall display features. Manufactured from high-density rigid polyurethane (150-220 kg/m³), these mantel frames provide structural stability and wood-like impact resistance without the structural weight of traditional stone or solid timber. Featuring a closed-cell physical composition, the material holds water absorption below 1%, ensuring long-term immunity to rot, mold, swelling, and insect infestation in all indoor conditions. Capable of enduring ambient thermal spans from -100 °C / +80 °C without shrinkage or warping, each mantel frame carries a B2 fire safety rating and comes pre-coated with white acrylic primer. Installation is completed using continuous lines of PU assembly adhesive along wall contact points paired with mechanical countersunk screws. Screw recesses and joinery seams are sealed with filler, sanded, and painted.
