The P2838B architectural ornament is a decorative pediment designed to elegantly accentuate the tops of door and window openings. Combining classic architectural details with modern material technology, this product is an ideal choice for architects and homeowners looking to add depth and character to their living spaces. Thanks to its smooth surface structure and crisp relief lines, it creates striking shadow plays on any surface it is applied to, forming an eye-catching focal point.
The product measures 140 mm in depth, 1080 mm in width, and 332 mm in height. These generous dimensions offer a perfect scale balance for standard door frames, wide windows, and fireplaces. Manufactured from high-density rigid polyurethane (150-220 kg/m³), this crown molding offers wood-like durability while remaining remarkably lightweight. Thanks to its closed-cell structure, its water absorption rate is below 1%, completely preventing rotting, swelling, or warping in humid environments, bathroom transitions, or exterior facades.
Looking at its visual design, elegant heart-shaped curves meeting at the center of a symmetrical structure stand out. Acanthus leaf reliefs flow gracefully outward from this central motif, ending in a gentle outward curl at the tips. The sharp detail definition entirely eliminates the bubbling or roughness common in traditional plaster moldings. Compared to wood alternatives, it does not attract insects, crack, or lose its shape by splintering over time.
With a wide range of applications, this decorative pediment is highly preferred not only for interior living room transitions or headboard designs but also for exterior window casing combinations. Demonstrating high dimensional stability against temperature fluctuations between -100 °C / +80 °C, it can be safely used in harsh weather conditions without expanding or contracting.
The product is delivered with a factory-applied primer coat. This primer layer facilitates the adhesion of the final topcoat. However, since paint manufacturers do not guarantee applications made without their own primers, applying an additional primer coat is entirely at the user's discretion. For outdoor applications, using UV-resistant paints is mandatory to protect the material from sunlight degradation.
- The P2838B polyurethane pediment model offers functional decoration solutions for both interior and exterior applications with its wide range of uses
- Indoors, it is used above living room door transitions, as a crown molding for wardrobes and headboard units in bedrooms, or to create a focal point above fireplace mantels
- It is highly preferred as a top ornament in wall paneling (wainscoting) projects in prestigious areas such as offices, hotel lobbies, and restaurants
- On exteriors, it is ideal for creating portal designs over entrance doors or crowning the tops of window casings to achieve a classic facade look
- For outdoor applications, painting with UV-protected paint after installation is highly recommended
- Installation of the P2838B pediment model must be carried out on a clean, dry, and smooth surface
- First, the installation area is determined and alignment lines are drawn
- Polure Polfix polyurethane adhesive, which has high bonding strength, is applied to the back surface of the product; silicon-based adhesives must never be used during installation
- After applying the adhesive, the product is placed on the wall, and mechanical fastening using screws is MANDATORY to prevent slipping until the adhesive cures
- Screw heads and gaps at the wall joints are filled with an exterior-grade filler
- Once cured, the surface is smoothed with 180-220 grit sandpaper
- Following an optional additional primer application, the installation is completed by painting with at least two coats of water-based or synthetic paint
- Thanks to the closed-cell structure of the polyurethane material, its maintenance is highly practical
- Dust accumulated indoors can be easily cleaned with a damp cloth
- For exterior use, mud or dust accumulated on the surface can be washed off by spraying low-pressure water
- Abrasive chemical cleaners containing thinners, acetone, or strong acids must be avoided during cleaning
- For exterior applications, it is recommended to inspect the paint surface every few years and refresh it if necessary to extend the life of the paint and renew UV protection
Will this product be affected by rain and sun on the exterior?
Thanks to its water absorption rate of under 1%, the P2838B polyurethane pediment is unaffected by rain and snow and will not rot. However, to provide protection against solar UV rays, it must be painted with a UV-resistant paint after exterior installation.
Is it sufficient to use only adhesive during installation?
No, for the safety and long-term durability of the product, mechanical fastening with screws is mandatory after applying Polure Polfix adhesive. Using only adhesive may lead to sagging or falling risks over time.
Can the product be used directly in white without being painted?
The product comes with a factory-applied white primer. However, painting the product after installation is necessary to conceal the screw and filler applications made during assembly, as well as to provide UV protection outdoors.
What advantages does it have compared to plaster pediment models?
Polyurethane pediments are extremely lightweight compared to plaster, carrying no risk of breaking or cracking during transport and installation. Furthermore, being moisture-resistant, they help maintain their original form over time in wet areas like bathrooms or on exterior facades.
Can it be sanded or touched up?
Yes, thanks to its high-density structure, polyurethane can be worked just like wood. After installation, once the filler applied to the screw holes dries, the surface can be smoothed with 180-220 grit sandpaper to achieve a perfect painting surface.
