Exterior Pilaster
Polure exterior pilasters bring timeless architectural dignity to building facades, entrance portals, and exterior wall framing. Manufactured from high-density rigid polyurethane (150-220 kg/m³), each pilaster offers wood-like mechanical durability and impact resistance without adding structural weight. Featuring a closed-cell structure with less than 1% water absorption, the profile will not swell, rot, or warp when exposed to severe rain, humidity, or extreme thermal variations between -100 °C / +80 °C. Rated fire class B2, the component arrives factory-treated with a white acrylic primer ready for custom finishing. Designed as decorative non-load-bearing hollow elements, they must enclose internal structural supports if load bearing is needed. Secure installation requires continuous PU assembly adhesive along rear contact surfaces paired with countersunk mechanical screws, followed by acrylic joint filling and light sanding prior to applying UV-resistant exterior paint.
Frequently Asked Questions
Can Polure exterior pilasters carry structural roof or balcony loads?
No, Polure exterior pilasters are decorative and hollow non-load-bearing elements. For structural support, an internal steel profile must be used.
What adhesive should be used for installing an exterior pilaster?
A continuous line of polyurethane assembly adhesive must be applied alongside mechanical screws. Standard silicone is strictly forbidden.
How do Polure exterior pilasters react to harsh weather conditions?
With water absorption below 1% and stability between -100 °C / +80 °C, they will not rot, swell, crack, or warp under severe weather.
What type of paint is required for exterior pilaster finishing?
After light sanding (180-220 grit) over the factory acrylic primer, paint with an elastic, UV-resistant exterior paint to prevent sun fading.
