Large Architectural Capital
Polure large architectural capitals bring grand classical proportions and intricate sculptural detail to monumental building facades and expansive luxury interiors. Manufactured from high-density rigid polyurethane (150-220 kg/m³), these substantial column crowns reproduce historical stone carving without the immense weight or structural danger of masonry. Their hollow interior design encases internal structural steel cores while maintaining strict dimensional stability across temperatures ranging from -100 °C / +80 °C. With closed-cell water absorption under 1%, these capitals will not decay, warp, or mold when exposed to rain and frost. Featuring a B2 fire safety classification, each capital comes factory pre-primed with white acrylic technical primer. Installation requires robust dual attachment: apply continuous polyurethane assembly adhesive on wall contact faces and joint seams, mechanical screw anchoring, filling joint seams with exterior acrylic sealant, and painting with UV-resistant paint.
Frequently Asked Questions
Are Polure large architectural capitals structural load-bearing components?
No, Polure large architectural capitals are decorative non-load-bearing elements. Structural loads must be sustained by an internal steel column profile.
What material is used for large architectural capitals?
They are crafted from high-density rigid polyurethane (150-220 kg/m³), offering wood-like mechanical durability and B2 fire rating.
Can concrete be poured inside a large architectural capital?
No, pouring concrete inside polyurethane column components is strictly forbidden as curing heat and expansion will crack the material.
How do you install large architectural capitals on building facades?
Mount using continuous PU assembly adhesive on joining surfaces combined with mechanical screws, fill joints with acrylic sealant, sand, and paint.
