Custom Appliques & Onlays

Why do details make all the difference?

High-quality architecture is always built on the contrast between volumes and detailing. Appliques and onlays allow you to emphasize proportions, highlight entry areas and pediments, or conceal structural joints. Just a few of these elements are enough to disguise technical components, transforming them into decorative accents. Using architectural appliques and onlays is the simplest way to add complexity and uniqueness even to a standard facade, while wall appliques and onlays do the same for commercial lobbies and residential interiors.

However, unlike simple off-the-shelf plastic appliques and onlays from home improvement stores, Decorative Architectural Shapes integrates architectural decor into the overall concept of a specific project. With custom architectural foam as our core focus, we handle the architectural fabrication of each piece for your project. This means that your onlays will perfectly match the building’s style, rather than looking like random glued-on plastic.

Where custom appliques and onlays work best

Because each element is made for a specific location, the same approach covers very different parts of a building. On the exterior, appliques and onlays are most often placed on the main facade, above entrances, on pediments and along cornices, where one well-proportioned ornament can anchor the whole composition. Symmetrical pairs placed on either side of an entrance make the entry read as the focal point of the facade. Inside, they are used on panels, door casings and fireplace surrounds, as well as in commercial lobbies, where visitors form their first impression of the space.

Historical restoration is another common task. When an original carved element has been lost or damaged, CNC technology allows us to replicate its shape precisely, and the polyurea coating protects the new piece over the long term. This way, an older building gets back its character without inheriting the maintenance problems of the original material.

Our clients include general contractors, architects, interior designers and property owners working on residential and commercial projects. Contractors value predictable installation, architects need the finished element to match the drawing, and owners want decor that keeps its appearance with little upkeep. Interior designers, in turn, look for pieces that can be adapted to a specific room rather than chosen from a catalog.

How decorative elements are engineered

Although our appliques serve a purely decorative purpose, they are essentially engineered products designed for many years of service:

• Core. Made from high-density Architectural Grade EPS. Unlike wood, this material is not susceptible to warping from moisture, which is critical for elements exposed to the outdoor environment. We take advantage of the opportunity to engineer the shape to minimize wind resistance. The core is also lightweight, which makes the elements easy to handle during installation.
• Protective coating. The key to durability is a layer of Premium Architectural Polyurea (60–100 mil). Unlike standard EIFS mesh, which cracks at corners and joints, elastomeric polyurea stretches along with the house. Each coating is applied according to a custom plan based on the purpose of the applique or onlay — such elements cannot be purchased off-the-shelf.
• Finish. We perform manual calibration of complex engineering assemblies, so carved appliques and onlays keep crisp detail. Every line of the bas-relief is refined to perfection.

From drawing to finished piece: our architectural fabrication process

Every project starts with the customer’s drawings or sketches. Whether you have a photo of a historical ornament, a detailed architectural drawing or only a concept for a new motif, it becomes the basis for the shape, scale and depth of relief. The design is then cut from EPS with CNC technology, which reproduces scrolls, floral motifs and other carved patterns with consistent accuracy from one piece to the next. The scale is set for the actual surface, so the proportions of the ornament work both up close and from the street.

After shaping, each piece receives its polyurea coating and is finished by hand, so the lines of the bas-relief stay sharp under the protective layer. The result is an element made for one project and one location, not a standard piece trimmed to fit on site. This also makes it easier for Decorative Architectural Shapes to keep appliques and onlays consistent in style with the other decorative elements of the building.

Comparison of solutions: why we are worth considering

Traditional materials have their limitations. Carved wood appliques and onlays require constant treatment to prevent rot and cracking; concrete elements require a massive foundation; and products made of ordinary, brittle foam without a coating break apart at the first impact or when water freezes.

Decorative Architectural Shapes offers a system that combines the best of both worlds: the realistic appearance of natural materials with the durability of polymers. Our solutions reduce the risk of cracking and delamination and provide minimum maintenance for decades to come. The elastic polyurea layer compensates for thermal expansion, so cracks do not form at the joints the way they can in rigid plaster systems. Unlike wood, the coated elements are moisture-resistant and do not require periodic repainting. The structure and coating are covered by a 20-year warranty, and based on our completed projects, the actual service life exceeds 50 years. For contractors, this means lower costs for correcting mistakes; for architects, it’s about precise forms; and for owners, it means aesthetic enjoyment without the hassle of maintenance.

How to choose the right applique or onlay

A few practical points help narrow down the design before you request a quote:

• Scale. Measure the panel, cornice, pediment or opening the element will sit on. An ornament that is too small looks lost on a large facade, while an oversized one can overwhelm a door casing or a fireplace mantel.
• Style. Match the motif to the architecture. Classical scrolls and acanthus leaves are good with traditional facades, while simplified geometric shapes are better suited to contemporary buildings.
• Depth of relief. Deep relief reads well from a distance on an exterior, while shallower detailing is often enough indoors, where the element is seen up close.
• Location. Note whether the piece will be exposed to the weather or installed indoors, and what surface it will be mounted on, so the construction and fastening can be planned in advance.
• References. Drawings, sketches or photos of existing ornaments speed up the design stage and help us reproduce the look you need.

Appliques and onlays for interiors

Inside a building, decorative elements are seen at arm’s length, so precise detailing matters even more than on a facade. A carved onlay centered on a fireplace mantel, a pair of appliques on a door casing or a repeating motif across wall panels gives a room a finished, architectural look without major construction work. In a commercial lobby, a custom composition can reflect the company’s brand or repeat a motif from the building’s exterior, connecting the interior with the facade. Because the elements are lightweight and fixed with adhesive and mechanical fasteners, they can be added during a renovation as well as in new construction. The moisture-resistant coating is also useful in entry areas, where interior elements are exposed to changing conditions.

Installation and compatibility

Decorative EPS elements are lightweight and are installed using adhesive and mechanical fasteners, so installation does not turn into a separate construction project. The elements are compatible with facade systems, including EIFS, which means appliques and onlays can become part of an EIFS facade rather than an add-on that fights with it. Lightweight pieces are also easier to position precisely, which helps keep symmetrical compositions aligned on a pediment or above an entrance.

What to send when you request a quote

To prepare an accurate quote, share as much of the following as you have: drawings or sketches of the ornament, photos of the facade or room where it will be installed, approximate dimensions of the surface, the number of elements, and whether they will be used outdoors or indoors. For historical restoration, photos of the surviving original details are especially useful, since they allow the new pieces to be matched to the existing ones. If there are no finished drawings yet, a description of the style and a few reference images are enough to start the conversation, and the design can be developed from there.

Decoration that looks incredibly natural

Our decorative elements don’t just adorn the facade — they also tie the entire design together stylistically. These elements can be crafted as custom compositions designed specifically for each project, including fireplace appliques and onlays, door casing details and entry accents. We can create decorative panels that reflect the location history, the company’s brand, or the owner’s personal preferences. If your project calls for linear ornament alongside decorative onlays and appliques, see our decorative trims. We support your project from concept to final installation, so that you can be confident in both the timeliness and quality of the result.

If you’re looking for a way to make your project look more upscale without increasing installation and operating costs, our solutions will be your best tool. We work at the crossroads of craftsmanship and engineering, creating designs that remain timeless regardless of architectural trends.
