Exterior Door Moulding
Polure exterior door mouldings deliver grand architectural framing to entrance portals, exterior front doors, and patio gateways. Manufactured from high-density rigid polyurethane (150-220 kg/m³), these exterior door trims offer wood-like mechanical strength and hail-proof impact protection without swelling or rotting like natural wood. Engineered with a closed-cell polymer structure with water absorption under 1%, they withstand heavy rains, humidity, and freeze-thaw weather cycles without warping or decaying. Thermally stable across temperatures from -100 °C / +80 °C and rated B2 for fire safety, they arrive pre-coated with factory white acrylic technical primer. Installation requires cutting 45° miter joints, applying continuous PU assembly adhesive along wall contact lines and joining edges, and securing with countersunk screws. Fill screw holes and joints with facade putty, sand smooth (180-220 grit), and paint with UV-resistant exterior facade paint.
Frequently Asked Questions
What material is used for Polure exterior door mouldings?
They are manufactured from high-density rigid polyurethane (150-220 kg/m³), providing hail resistance, B2 fire rating, and high impact durability.
Will exterior door moulding rot or swell from rain exposure?
No, with water absorption below 1% and closed-cell polymer structure, polyurethane mouldings will never rot, swell, or absorb rain.
How is exterior door moulding installed?
It is installed using continuous PU assembly adhesive on contact edges combined with countersunk screws. Silicone is strictly forbidden.
Does exterior door moulding require UV protective paint?
Yes, for exterior applications, it must be painted with UV-resistant exterior facade paint to prevent solar yellowing.
