Exterior Architraves
Polure exterior architraves deliver grand architectural framing to building entrances, exterior doors, and facade window surrounds. Precision-molded from rigid high-density polyurethane (150-220 kg/m³), these exterior trims provide wood-like mechanical durability and impact resistance (withstanding hail and environmental stress) without warping or rotting. Their closed-cell polymer structure maintains water absorption strictly below 1%, making them impervious to heavy rain, frost, coastal humidity, and mold growth. Operating reliably across temperatures from -100 °C / +80 °C with Class B2 fire safety certification, each length is pre-coated with factory white acrylic primer. Installation onto facade surfaces requires cutting 45° miter joints with a fine-tooth saw, applying a continuous bead of polyurethane assembly adhesive across back contact faces and miter edges (silicone is strictly forbidden), and securing with countersunk mechanical screws. Fill screw heads and joints with facade filler, sand smooth with 180-220 grit paper, and apply two coats of UV-resistant exterior paint.
Frequently Asked Questions
Will Polure Exterior Architraves rot or swell when exposed to outdoor rain?
No, with closed-cell polyurethane construction and water absorption below 1%, they will never rot, swell, or cultivate mold outdoors.
What density material is used in Polure Exterior Architraves?
They are manufactured from high-density rigid polyurethane (150-220 kg/m³), offering wood-like durability and hail resistance.
What type of paint should be used on Exterior Architraves outdoors?
Outdoors, you must apply two coats of elastic, UV-resistant exterior paint to prevent UV fading.
Is silicone adhesive allowed for installing Exterior Architraves?
No, silicone is strictly forbidden. You must use polyurethane assembly adhesive combined with mechanical screws.
