The P8021A decorative facade element is designed to serve as a crowning detail for window tops and door jamb systems. Combining the rich relief art of classical architecture with modern material technology, this product adds depth and character to exterior facades or prestigious interior designs. With its large-scale and voluminous structure, it creates a focal point on facades, transforming ordinary wall surfaces into monumental architectural statements.
This product features dimensions of 267 mm in depth, 652 mm in width, and 493 mm in height. These substantial proportions offer a balanced scale, particularly in high-ceilinged spaces and wide villa facades. Manufactured from high-density rigid polyurethane (150-220 kg/m³), it delivers wood-like durability while remaining lightweight to avoid adding unnecessary load to the structure. Its closed-cell structure prevents water and moisture absorption, completely eliminating risks of freezing, cracking, or rotting. Furthermore, it exhibits high dimensional stability against temperature fluctuations ranging from -100 °C / +80 °C.
The design details, featuring symmetrical acanthus leaves, a central oval medallion, and circular bead motifs, infuse the product with a classic Baroque elegance. The sharpness of the carved and embossed surface details offers a level of smoothness and clarity unattainable with traditional plasterwork. This deep relief structure creates aesthetic shadow plays on the facade in daylight, highlighting the architectural quality of the building.
This versatile piece can be positioned as a keystone or pediment at the top center of windows, or as a portal ornament for doorways. Indoors, it can be elegantly used for classic fireplace mantels, supporting column capitals, or as a decorative corbel in large wall panel designs. Thanks to its lightweight nature, it saves labor and time during installation, and unlike fragile plaster, it prevents waste from breakage during transport and application.
The product is shipped with a factory-applied primer coat on its surface, which facilitates the adhesion of the final topcoat. However, since paint manufacturers do not guarantee applications made without their own priming products, applying an additional primer before installation is optional and at the customer's discretion. Polure does not assume responsibility for paint performance. For exterior applications, UV-resistant paints must be used to prevent yellowing of the material.
- The P8021A decorative window pediment is highly favored in both exterior and interior projects due to its versatile application areas
- Externally, it is used for villa window headers, as a keystone at the center of door arches, and as a decorative support at wall molding intersections
- Internally, it delivers outstanding results as a fireplace mantel crown in classic living room designs, or as an overdoor accent in wide corridors and lobby entrances
- It can also serve as a corbel or bracket to enhance the classical atmosphere in restaurants, hotel lobbies, and historic building restoration projects
- The application surface must be completely free of dust, moisture, and grease
- Apply Polure Polfix polyurethane adhesive to the back of the product and position it on the wall
- Since this is a heavy and voluminous piece, mechanical fastening with stainless steel screws is mandatory to secure the product until the adhesive cures
- Screw heads and joints should be filled with exterior-grade putty and sanded smooth with 180-220 grit sandpaper
- The factory primer is ready for painting; however, applying an additional primer for paint warranty purposes is entirely at the user's discretion
- Complete the process by applying at least two coats of UV-resistant paint for exteriors, or water-based/synthetic paint for interiors
- Due to its polyurethane composition, the product is completely resistant to water and moisture, making maintenance exceptionally easy
- For interior spaces, it can be easily cleaned with a damp or soapy cloth
- For exteriors, it can be washed with low-pressure water to remove dust
- Abrasive chemicals and stiff brushes must be avoided during cleaning
- In exterior applications, it is recommended to inspect the painted surface every few years and repaint if necessary to extend the paint's lifespan and maintain its UV resistance
Can this product withstand harsh outdoor weather conditions?
Yes, manufactured from rigid polyurethane, the P8021A model is resistant to temperatures ranging from -100 °C / +80 °C. Thanks to its closed-cell structure, its water absorption rate is below 1%, meaning it will not crack or rot due to rain, snow, or frost. For long-lasting exterior use, it must be painted with UV-resistant paint after installation.
Which adhesive should I use during installation?
Only Polure Polfix polyurethane adhesive should be used for installation. Silicone or similar flexible adhesives do not provide long-term durability. Additionally, due to the voluminous structure of this model, mechanical fastening with stainless steel screws is mandatory alongside the adhesive for a secure installation.
Can the product be installed directly without being painted?
The product comes with a white factory-applied primer. However, unpainted polyurethane material may yellow over time due to exposure to sunlight (UV). Therefore, painting the product after installation is highly recommended. The factory primer prepares the surface for painting, while applying an additional primer is an optional choice based on the paint manufacturer's warranty terms.
What advantages does it offer compared to plaster or wood ornaments?
Polyurethane is significantly lighter and shatterproof compared to plaster, reducing the load on the building facade and simplifying installation. Unlike wood, it is unaffected by moisture, meaning it won't warp, crack, or attract pests. Compared to EPS foam products, it is highly impact-resistant, and its surface design details are much sharper and more defined.
What are the exact dimensions of the product, and does it fit every project?
The product measures 267 mm in depth, 652 mm in width, and 493 mm in height. Due to its prominent and high-relief structure, it provides a perfect scale and rich presence, particularly on wide windows, villa entrances, and high-ceilinged classical interior designs.
