Exterior Building Corner Trim
Polure exterior building corner trim provides clean architectural framing and protective quoining for outer facade corners. Molded from high-density rigid polyurethane (150-220 kg/m³), this exterior trim offers wood-equivalent mechanical strength that effectively resists hail impacts without denting. Featuring a closed-cell physical matrix with water absorption under 1%, it will not absorb moisture, swell, rot, or degrade during freeze-thaw cycles. Tested to operate between -100 °C / +80 °C with B2 fire retardancy, every length is pre-coated in factory white acrylic primer. Installation requires clean masonry, continuous polyurethane assembly adhesive on wall contact backs, and mechanical countersunk screw fixings. Silicone bonding is strictly forbidden. Joint lines and screw holes are filled with exterior acrylic facade filler, sanded smooth with 180-220 grit, and finished with UV-resistant elastic facade paint.
Frequently Asked Questions
What material is Polure exterior building corner trim made from?
It is molded from high-density rigid polyurethane (150-220 kg/m³), providing timber-like strength, hail resistance, and a B2 fire safety rating.
Is exterior building corner trim resistant to severe winter conditions?
Yes. Water absorption is under 1%, preventing moisture penetration, rot, or cracking during freeze-thaw cycles down to -100°C.
How is exterior building corner trim properly mounted?
Apply continuous PU assembly adhesive to contact backs and secure with countersunk screws. Silicone is forbidden. Fill joints with facade putty.
What paint finish is required for outdoor building corner trim?
Exterior installations require elastic, UV-resistant facade paint applied in matching primer systems to prevent fading.
