Exterior Pilaster Capital
Polure exterior pilaster capitals provide weather-hardened architectural crowning capitals designed specifically to top exterior wall pilasters, portal surrounds, and facade projections. Molded from high-density rigid polyurethane (150-220 kg/m³), these flat-backed capitals deliver wood-like physical strength and high impact resistance, protecting facade tops from wind shear and outdoor elements. Their closed-cell structural body retains water absorption strictly under 1%, ensuring they will not rot, swell, warp, or foster mold growth under heavy rain, freeze-thaw cycles, or humidity. Rated B2 for fire safety and stable from -100 °C / +80 °C, each capital comes factory pre-primed with white acrylic technical primer and requires final painting with UV-resistant exterior facade paint. Installation requires dual fastening using polyurethane assembly adhesive and mechanical screws.
Frequently Asked Questions
What is the primary function of a Polure exterior pilaster capital?
An exterior pilaster capital serves as the decorative crowning capital for wall-mounted pilasters on exterior building facades.
Are Polure exterior pilaster capitals load-bearing?
No, Polure exterior pilaster capitals are non-load-bearing decorative elements.
What density material is used for exterior pilaster capitals?
They are molded from high-density rigid polyurethane (150-220 kg/m³), providing wood-like physical durability.
How are exterior pilaster capitals protected against outdoor weather?
They have less than 1% water absorption and withstand temperatures from -100 °C / +80 °C. They must be painted with UV-resistant exterior paint after installation.
Can silicone adhesive be used to mount exterior pilaster capitals?
No, silicone adhesive is strictly forbidden because it lacks structural bonding capability. Only polyurethane assembly adhesive paired with mechanical screws must be used.
