Balustrade Capping Profile
Balustrade capping profiles manufactured from high-density rigid polyurethane (150-220 kg/m³) provide weather-defying protective top rails for outdoor balconies and staircase balustrades. Engineered to offer wood-like impact toughness and structural strength, these capping profiles will not rot, warp, or crack under freezing conditions or extreme heat (-100 °C / +80 °C). Their closed-cell structural formulation keeps water absorption strictly under 1%, making them ideal for long-term exterior exposure. Factory pre-coated with a white acrylic technical primer, Polure balustrade capping profiles require an elastic, UV-resistant exterior facade topcoat paint. Installation calls for clean substrate preparation, 45° miter joints, continuous PU assembly adhesive, and mechanical screw fixing (silicone adhesive is strictly forbidden). Lightly sand with 180-220 grit paper prior to painting for ideal coating durability.
Frequently Asked Questions
Why is polyurethane ideal for balustrade capping profiles?
High-density polyurethane (150-220 kg/m³) offers wood-like mechanical toughness, rot-proof longevity, water absorption under 1%, and hail resistance.
What paint should be applied to balustrade capping profiles?
Topcoat with an elastic, UV-resistant exterior paint system. Ensure topcoat primer brand matches topcoat system brand for optimal durability.
How is a balustrade capping profile installed?
Mount using a continuous bead of PU assembly adhesive along with mechanical screws. Silicone is strictly forbidden.
