Carved Fretwork Grille
Polure carved fretwork grilles present intricate openwork lattice designs and architectural screening for ventilation covers, wall panels, and ceiling inserts. Manufactured from high-density rigid polyurethane (150-220 kg/m³), these grilles replicate fine hand-carved woodwork while offering superior impact resistance and structural stability. Their closed-cell construction guarantees water absorption under 1%, preventing rot, swelling, or mold growth in kitchens, bathrooms, or humid environments. Featuring a B2 fire safety rating and operating across temperatures from -100 °C / +80 °C, they ensure long-term durability. Shipped pre-primed in factory white acrylic, installation requires continuous PU assembly adhesive on contact edges paired with countersunk screws. Fill screw holes with acrylic filler, sand smooth, and finish with water-based or synthetic paint.
