Exterior Pilaster Shaft
Polure exterior pilaster shafts feature weather-hardened architectural profiles designed to create vertical relief and shadow lines on exterior building facades and portal surrounds. Molded from high-density rigid polyurethane (150-220 kg/m³), these flat-backed shafts deliver wood-equivalent physical strength and high impact resistance while maintaining a lightweight form for easy wall assembly. Their closed-cell structural composition retains water absorption strictly under 1%, ensuring they will not warp, swell, rot, or harbor mold under heavy rain, freeze-thaw cycles, or humidity. Rated B2 for fire safety and stable from -100 °C / +80 °C, each shaft arrives factory pre-primed with white acrylic technical primer and requires UV-resistant exterior facade paint. Installation requires dual fastening using polyurethane assembly adhesive and mechanical screws.
Frequently Asked Questions
What characterizes a Polure exterior pilaster shaft?
An exterior pilaster shaft features a weather-resistant flat-backed profile designed for vertical architectural framing on exterior walls.
Are Polure exterior pilaster shafts load-bearing?
No, Polure exterior pilaster shafts are non-load-bearing decorative wall elements.
What density material is used for exterior pilaster shafts?
They are molded from high-density rigid polyurethane (150-220 kg/m³), providing wood-like physical strength and impact resistance.
How are exterior pilaster shafts attached to facade walls?
Apply continuous lines of PU assembly adhesive along all joining edges and wall contact surfaces, then secure with countersunk mechanical screws. Fill screw heads with putty, sand, and paint with exterior paint.
Can silicone adhesive be used to bond exterior pilaster shafts?
No, silicone adhesive is strictly forbidden because it lacks structural bonding capability. Only polyurethane assembly adhesive paired with mechanical screws must be used.
