Exterior Balcony Railing
Polure exterior balcony railings deliver classic architectural grandeur and enduring safety for outdoor facades and terrace designs. Manufactured from high-density rigid polyurethane (150-220 kg/m³), these railing systems offer wood-like mechanical toughness without risking rot or structural degradation. Their closed-cell structure maintains water absorption strictly under 1%, ensuring the railing will not swell, crack, or harbor mold under heavy rainfall or winter freeze. Engineered for ambient temperatures between -100 °C / +80 °C, they carry a B2 fire safety classification. Each component is factory-primed with white acrylic technical primer. Proper installation requires thorough surface preparation, 45° miter joints cut with a fine-tooth saw, continuous PU assembly adhesive on all joints, and stainless steel screw anchoring. Seal joints and countersunk screws with facade filler, sand smooth with 180-220 grit, and finish with elastic, UV-resistant exterior paint.
Frequently Asked Questions
What material is used in Polure exterior balcony railing systems?
Polure exterior balcony railings are made from high-density rigid polyurethane (150-220 kg/m³), offering high impact resistance, lightweight design, and B2 fire class rating.
Will an exterior balcony railing withstand frost and moisture?
Yes. With water absorption under 1% and thermal resistance from -100 °C / +80 °C, the railing will not rot, swell, or deteriorate outdoors.
How is the exterior balcony railing properly installed?
Install using continuous PU assembly adhesive along contact faces combined with mechanical screw attachment. Joints and screw holes are filled with facade putty, sanded (180-220 grit), and painted.
Can silicone adhesive be used for exterior balcony railing installation?
No, silicone is strictly prohibited as it cannot handle structural outdoor loads. Only polyurethane assembly adhesive paired with screws must be used.
What paint should be applied to an exterior balcony railing?
After lightly sanding the factory acrylic primer with 180-220 grit sandpaper, apply two coats of elastic, UV-resistant exterior paint.
