Balustrade Top Rail
Polure balustrade top rails provide refined architectural capping and structural completion for balcony and staircase balustrade systems. Manufactured from high-density rigid polyurethane (150-220 kg/m³), these handrails deliver timber-like mechanical durability without the risk of splitting, warping, or rotting. Their closed-cell structure keeps water absorption below 1%, ensuring complete immunity to rainwater, frost, and mold. Engineered for operational stability between -100 °C / +80 °C, each section holds a B2 fire safety rating. Delivered with a factory-applied white acrylic technical primer, the top rail is ready for topcoating. Installation requires precise miter cuts with a fine-tooth saw, continuous PU assembly adhesive on contact edges, and mechanical countersunk screw attachment. Fill joints and screw heads with facade putty, sand smooth with 180-220 grit, and finish with elastic UV-resistant paint.
Frequently Asked Questions
What material is used in the manufacturing of the Polure balustrade top rail?
The Polure balustrade top rail is manufactured from high-density rigid polyurethane (150-220 kg/m³), offering wood-like impact strength and B2 fire safety class.
Is the balustrade top rail suitable for outdoor balcony installations?
Yes. Featuring water absorption under 1% and thermal stability between -100 °C / +80 °C, it will not rot, swell, or warp outdoors.
How is the balustrade top rail correctly mounted?
Apply continuous PU assembly adhesive on all contact edges and secure with countersunk screws. Fill screw heads and joints with putty, sand with 180-220 grit, and paint.
Can silicone adhesive be used to mount the balustrade top rail?
No. Silicone is strictly forbidden as it lacks structural load-bearing adhesion. Only polyurethane assembly adhesive paired with screws must be used.
What paint finish is recommended for the balustrade top rail?
After lightly sanding the factory white acrylic primer with 180-220 grit sandpaper, apply two coats of elastic, UV-resistant exterior paint.
