Exterior Facade Frames
Polure exterior facade frames deliver timeless architectural definition around building windows, doors, and entryway surrounds. Engineered specifically for harsh outdoor conditions from high-density rigid polyurethane (150-220 kg/m³), these exterior moldings resist mechanical impacts, hail, and structural stress. Their closed-cell polymer core ensures under 1% water absorption, completely eliminating risks of rotting, swelling, or frost damage. Rated B2 for fire resistance and stable from -100 °C / +80 °C, each frame arrives pre-coated with a white technical acrylic primer. Installation mandates a dual fixing system: apply a continuous bead of PU assembly adhesive along all wall contacts and joint seams, then anchor mechanically with heavy-duty countersunk screws (screw outdoor pieces to each other at joints). Fill screw heads and joints with exterior facade putty, sand flush with 180-220 grit, and finish with elastic, UV-resistant exterior facade paint to prevent UV degradation.
Frequently Asked Questions
What density material is used for Polure exterior facade frames?
Exterior facade frames are crafted from high-density rigid polyurethane (150-220 kg/m³), delivering wood-like strength and resistance to hail.
Are exterior facade frames affected by freeze-thaw cycles or rain?
No, with water absorption below 1% and thermal stability between -100 °C / +80 °C, they will not crack, swell, or rot in freezing rain.
What paint must be applied to exterior facade frames?
They must be painted with an elastic, UV-resistant exterior paint to protect the factory primer from long-term solar UV degradation.
How are exterior facade frames installed securely on outdoor walls?
Installation requires continuous PU assembly adhesive on all contact edges, countersunk mechanical screws, and screwing adjacent pieces to each other at joints.
