Light Trough Profile
Polure light trough profiles provide dedicated recessed housing channels for indirect ambient lighting along ceilings. Precision-molded from rigid high-density polyurethane (150-220 kg/m³), these structural lighting troughs combine high mechanical strength with lightweight handling. Featuring a closed-cell polymer structure with water absorption under 1%, they resist warping, rot, and mold in moisture-prone rooms like bathrooms. Certified fire safety class B2 and thermally stable between -100 °C / +80 °C, all profiles arrive pre-coated with factory white acrylic primer. Installation is completed by applying continuous polyurethane assembly adhesive along contact edges and reinforcing with countersunk mechanical screws.
Frequently Asked Questions
What density material is used for Polure light trough profiles?
They are molded from rigid high-density polyurethane (150-220 kg/m³).
Are light trough profiles affected by heat from lighting?
No, they maintain structural stability within a temperature range of -100 °C / +80 °C.
How are light trough profiles anchored to walls or ceilings?
Apply continuous PU assembly adhesive to contact edges, fix with countersunk mechanical screws, fill, sand, and paint.
Is silicone adhesive permitted for installation?
No, silicone is strictly forbidden due to insufficient adhesion; specialized PU assembly adhesive is required.
