Polyurethane Beam End Cap
Polure polyurethane beam end caps provide a polished, authentic conclusion to faux wood ceiling beams, exposed rafters, and rustic interior framing. Formed from high-density rigid polyurethane (150-220 kg/m³), these end caps capture detailed wood grain textures while maintaining a lightweight composition that simplifies overhead installation. The non-porous closed-cell material absorbs less than 1% water, ensuring absolute immunity to swelling, rot, or insect infestation in kitchens or humid environments. Thermal resistance spanning -100 °C / +80 °C and a B2 fire safety rating guarantee long-term stability. Delivered factory-primed with a smooth white acrylic coat, each cap can be easily trimmed with a fine-tooth handsaw. Mount using continuous polyurethane assembly adhesive on contact edges and secure with countersunk screws. Fill fixing holes with acrylic putty and sand smooth prior to applying topcoat paint.
Frequently Asked Questions
What is the function of a polyurethane beam end cap?
It seals and decorates the open ends of faux wooden beams, providing a clean, realistic log or timber cross-section look.
Are polyurethane beam end caps resistant to moisture and insects?
Yes, with water absorption below 1%, high-density polyurethane will never rot, swell, or attract wood-boring insects.
How do you install a polyurethane beam end cap onto a ceiling beam?
Apply continuous PU assembly adhesive to joining edges and secure with countersunk mechanical screws. Fill holes with putty and sand.
Can polyurethane beam end caps be painted or stained?
Yes, light sanding (180-220 grit) over the factory acrylic primer allows application of water-based or synthetic paints and wood glazes.
