Individual components for the KPEN11 polyurethane window surround and molding set
Create a classic exterior look with matching parts for the KPEN11 window trim. This set includes P2839 pediment, P9927 and P6065 decorative brackets, and P1459, P1458, P1456 framing profiles. All components fit together seamlessly.












The KPEN11 architectural window surround set offers an elite framing solution for premium building facades. This grand assembly transforms standard window openings into majestic focal points, drawing inspiration from classical Roman and Renaissance architecture. By combining a highly decorative pediment with matching side pilasters, it delivers an instant upgrade to the structural aesthetics of high-end residential and commercial properties.
Measuring 2000 mm in width, 2280 mm in height, and with a prominent depth of 217 mm, this robust framing system provides exceptional dimensional stability. Fabricated from high-density rigid polymer (150-220 kg/m³), it mimics the look and density of carved wood but is highly resistant to moisture, decay, and insect damage. Unlike heavy concrete or plaster alternatives, this lightweight structure imposes minimal static load on the building's exterior wall, while offering resilient performance across a wide temperature spectrum from -20 °C / +70 °C.
Aesthetically, the KPEN11 set is characterized by its exquisite symmetrical detailing. The top pediment showcases a central coat-of-arms crest flanked by elegant scrollwork and floral carvings. The side pilasters feature intricate acanthus leaf brackets and fluted columns that terminate in detailed base blocks. This elaborate combination produces a striking three-dimensional relief, creating deep shadow lines that enhance the architectural character of any facade.
This ornate trim package is designed specifically for large-scale window openings on luxury villas, historic restorations, boutique hotel facades, and upscale estates. It serves as an impressive architectural statement on main facades, entrance windows, or grand reception halls where classical grandeur is desired. The white factory-primed surface is ready to be coated with any high-quality UV-resistant paint to perfectly match your exterior color palette.
Installing this polymer set is significantly faster and cleaner than handling heavy cast stone or gypsum. The components are cut, positioned, and fixed using a high-strength polyurethane (PU) mounting adhesive, supplemented by mechanical screws for long-term safety. Minor seams can be filled, sanded, and painted to achieve a seamless, monolithic appearance that outperforms wood and EPS alternatives in both durability and detail preservation.
- The KPEN11 decorative framing set is primarily engineered for premium exterior window trim, but its architectural versatility allows for broader applications
- It is ideal for showcasing grand front-facing windows of luxury villas, classical country houses, and heritage building restorations
- On commercial properties, it elevates the street presence of boutique hotels, upscale restaurants, and embassy buildings
- For large-scale interior spaces, such as high-ceilinged hotel lobbies, grand ballrooms, or luxury home libraries, this set can be used to frame monumental interior windows or decorative mirrors
- To maximize its visual impact, pair it with complementary architectural elements like dentil moldings, corbels, or rusticated corner stones on the building facade
- Ensure a UV-resistant topcoat is applied for all outdoor installations to preserve the crisp details and pristine finish
- Ensure the installation surface is dry, clean, and structurally sound
- Begin by carefully measuring and dry-fitting the pediment and side pilasters
- Apply a generous bead of high-performance polyurethane (PU) mounting adhesive (do not use standard silicone) to the back of each component
- Press the pieces firmly against the wall and secure them mechanically using corrosion-resistant screws to ensure permanent stability
- Fill all screw holes and joints with a durable exterior-grade acrylic filler
- Once the filler is dry, sand the areas smooth using 180-220 grit sandpaper
- While the product comes with a factory-applied primer, applying an additional optional primer is recommended to ensure optimal paint adhesion
- Finish the installation by applying two coats of high-quality, UV-resistant exterior paint
- The high-density polymer composition makes maintenance remarkably simple
- For outdoor installations, the frame can be cleaned periodically using low-pressure water or a soft brush with mild soap to remove dust and environmental buildup
- Avoid using high-pressure power washers at close range
- For interior settings, a simple wipe down with a damp cloth is sufficient
- If the surface is accidentally chipped or scratched, it can be easily repaired by applying a small amount of exterior filler, sanding it smooth, and applying a quick paint touch-up
- Checking the paint finish every few years is recommended to ensure continuous UV protection
Is the KPEN11 window surround suitable for extreme outdoor weather conditions?
Yes, the KPEN11 set is highly durable and engineered to withstand extreme climates. Made from high-density rigid polymer, it features a closed-cell structure that absorbs less than 1% moisture, making it resistant to rain, snow, rot, and frost. It maintains excellent dimensional stability in temperatures ranging from -20 °C / +70 °C without warping or cracking.
What are the advantages of this polymer material over traditional cast concrete or plaster?
Unlike heavy concrete or gypsum plaster, this polymer material is extremely lightweight, which prevents added structural stress on your building's walls and simplifies the installation process. It is highly impact-resistant, finely detailed, and suitable for areas exposed to moisture and insect damage, offering durable performance with minimal maintenance compared to wood or plaster.
Does the window surround come pre-painted, and what paint should I use?
The product is delivered with a white factory-applied primer coat, preparing the surface for painting. For outdoor installations, it is mandatory to apply a high-quality, UV-resistant exterior paint to prevent yellowing. For indoor installations, any water-based or synthetic paint can be used. Applying an additional primer before painting is optional but recommended by paint manufacturers.
What adhesive should be used for mounting this window frame?
For a secure and permanent bond, always use a high-strength polyurethane (PU) mounting adhesive. Do not use standard silicone adhesives, as they do not provide the necessary structural hold. Additionally, mechanical fastening with corrosion-resistant screws is required to ensure long-term safety and stability.
Can the dimensions of the KPEN11 window frame set be adjusted?
The KPEN11 is a fixed-dimension combined set measuring 2000 mm in width and 2280 mm in height. However, for minor adjustments, the side pilasters can be carefully trimmed at the base using standard woodworking tools before mounting. For larger or custom-sized windows, please contact our technical support team to discuss modular combinations.
