Exterior Pilaster Base
Polure exterior pilaster bases deliver weather-resistant plinth foundations engineered specifically to ground wall-mounted exterior pilasters and facade entrance portals. Molded from high-density rigid polyurethane (150-220 kg/m³), these flat-backed bases offer wood-equivalent physical strength and high impact resistance, shielding facade bases from foot traffic and splashback. Their closed-cell structural composition retains water absorption strictly under 1%, ensuring they will not rot, swell, warp, or foster mold in freeze-thaw climates or rain-soaked outdoor conditions. Rated B2 for fire safety and stable from -100 °C / +80 °C, each base arrives factory pre-primed with white acrylic technical primer and requires UV-resistant exterior facade paint. Installation requires dual attachment using polyurethane assembly adhesive and mechanical screws.
Frequently Asked Questions
What is the primary function of a Polure exterior pilaster base?
An exterior pilaster base serves as the flat-backed bottom plinth foundation for wall pilasters installed on exterior building facades.
Are Polure exterior pilaster bases load-bearing?
No, Polure exterior pilaster bases are strictly non-load-bearing decorative elements.
What density material is used for exterior pilaster bases?
They are molded from high-density rigid polyurethane (150-220 kg/m³), offering wood-like strength and high impact resistance near ground level.
How are exterior pilaster bases protected against rain and sun?
Their closed-cell structure keeps water absorption under 1%. They must be painted with UV-resistant exterior facade paint after mounting.
Can silicone adhesive be used to mount exterior pilaster bases?
No, silicone adhesive is strictly forbidden because it lacks structural bonding capability. Only polyurethane assembly adhesive paired with mechanical screws must be used.
