Exterior Pilaster Molding
Polure exterior pilaster moldings bring refined vertical architectural emphasis and classical trim detail to building facades. Crafted from high-density rigid polyurethane (150-220 kg/m³), these facade trims offer wood-like mechanical durability while being light in weight. Their closed-cell structure maintains water absorption strictly below 1%, protecting exterior walls against moisture, rotting, swelling, and mold growth. Thermal resistance from -100 °C / +80 °C guarantees that the moldings will not shrink, warp, or crack under harsh weather conditions. Certified B2 for fire safety, each length is factory pre-treated with white acrylic technical primer. Installation requires dual fastening: continuous polyurethane assembly adhesive on wall contact faces and mitered joint edges paired with mechanical screws. Fill joints with facade putty, sand smooth, and finish with elastic UV-resistant exterior paint.
Frequently Asked Questions
What material is used for Polure exterior pilaster moldings?
Polure exterior pilaster moldings are manufactured from high-density rigid polyurethane (150-220 kg/m³), offering wood-like strength and B2 fire rating.
Will exterior pilaster moldings rot or warp in rain?
No, with closed-cell water absorption under 1% and resistance from -100 °C / +80 °C, they will not absorb water, warp, or rot.
How do you install exterior pilaster moldings on facades?
Clean the wall, cut 45° miters, apply continuous PU assembly adhesive on contact edges, secure with screws, fill joints, and paint with exterior paint.
Is silicone adhesive permitted for exterior pilaster molding mounting?
No, silicone is strictly forbidden because it lacks structural bonding strength. Polyurethane assembly adhesive combined with screws must be used.
