Classical Column Ring
Polure classical column rings add refined detail and transition aesthetics to interior and exterior columns. Manufactured from high-density rigid polyurethane (150-220 kg/m³), these rings offer wood-like mechanical durability and crisp detail without structural weight. Their closed-cell construction keeps water absorption under 1%, preventing rot, swelling, and mold in humid environments or outdoor facades. Engineered for temperatures from -100 °C / +80 °C with a B2 fire safety rating, each ring is delivered pre-primed in white acrylic primer. Installation uses continuous PU assembly adhesive along contact rims combined with countersunk screws. Paint with water-based indoor or elastic outdoor paint.
Frequently Asked Questions
What material is used for Polure classical column rings?
Polure classical column rings are made of high-density rigid polyurethane (150-220 kg/m³), offering high mechanical strength and B2 fire resistance.
Are classical column rings weather resistant?
Yes, with water absorption below 1%, they will not rot, swell, or mold, remaining dimensionally stable from -100 °C / +80 °C.
How do you install classical column rings?
Apply continuous PU assembly adhesive on joining surfaces and secure with countersunk screws. Fill screw holes with acrylic filler and sand smooth before painting.
Can silicone adhesive be used for classical column rings?
No, silicone is strictly forbidden as it lacks mechanical bonding strength. Use polyurethane assembly adhesive paired with screws.
