Door Casing Base Block
Polure door casing base blocks establish a refined architectural connection between door frames and floor plinths. Manufactured from high-density rigid polyurethane (150-220 kg/m³), these plinth blocks provide wood-like mechanical durability while avoiding cracking and splintering during installation. Designed with a closed-cell structure with water absorption under 1%, they resist floor washing moisture, humidity, and mold growth. Operating within extreme temperature ranges of -100 °C / +80 °C and rated B2 for fire safety, each base block is factory pre-coated with a white acrylic primer. Installation is completed using a dual attachment method: continuous PU assembly adhesive on contact faces and countersunk screw fixings, followed by acrylic filler application and painting.
Frequently Asked Questions
What material is used for Polure door casing base blocks?
Polure door casing base blocks are made from high-density rigid polyurethane (150-220 kg/m³), delivering wood-like impact strength and a B2 fire safety rating.
Are door casing base blocks resistant to water from floor mopping?
Yes. With a closed-cell structure and water absorption below 1%, door casing base blocks will not rot, swell, or mold when exposed to moisture.
How should a door casing base block be installed?
Apply continuous PU assembly adhesive on contact edges and secure with countersunk screws. Silicone is forbidden. Fill screw heads with acrylic filler and sand prior to painting.
What paint options can be applied to a door casing base block?
They arrive pre-primed in white acrylic. Standard indoor applications use two coats of water-based or synthetic paint, while outdoor use requires UV-resistant paint.
Does a door casing base block warp over time?
No, high-density polyurethane remains dimensionally stable between -100 °C / +80 °C without shrinking, warping, or cracking.
