Single-Family Residential
Production schedules leave little room for surprises, and at Belco, we don’t think they should have to. Our products give single-family home builders consistent quality that installs quickly (often with one set of hands vs. two). Additionally, Belco XT Products resist rot and warping, ultimately reducing installation costs and callbacks.

Individual Exterior Trim Applications
Fascia Board
Horizontal boards attached to rafter/truss ends at the eaves or face of the overhang. Serves as a termination point for roof sheeting, while also providing an additional positive nailing surface. Also provides an extra layer of protection between the gutter and truss tails. Typically 2×8
Fascia is one of the most visible (and most vulnerable) parts of a home. Belco XT fascia arrives straight, factory-primed, and ready to install in longer lengths that reduce joints, waste, and returns. That means builders finish faster with fewer callbacks, and dealers move inventory that performs consistently instead of piling up in the cull bin.
Quick Tip: – Belco XT Plowed Fascia includes a built-in bevel and relief cut for water runoff, eliminating the need for add-on drip strips. Crews save labor on-site, and dealers gain a product that installs right the first time, protecting deadlines and profit margins. It’s the one-step fascia solution.
Bargeboard
Exterior house trim along a gable. Similar to fascia, but with a specific application for gables. Provides a decorative finish while protecting the roof structure from weather damage. Bargeboard also provides a positive nailing surface for the roof sheeting. Typically 2×8
At the gable ends, bargeboard trim takes the brunt of wind and weather beating. Belco XT bargeboard offers the strength and stability needed for clean lines along the roof peak, with saturated preservative treatment and factory priming that protects against moisture intrusion where failures are most common. Its longer lengths simplify layout and reduce splices, keeping both curb appeal and project schedules on point.
Quick Tip: – When installing bargeboard, fewer joints mean less risk of water entry and paint failure. Belco’s extended lengths (up to 20 feet) enable crews to span gables with fewer cuts, saving labor and reducing the likelihood of callbacks.
Garage Door Trim
Decorative trim enclosing the garage framing members. Enhances the aesthetic appeal of the garage and protects against moisture and pests. Typically 2×8
Garage doors are often an exterior elevation focal point, making trim choice a higher-stakes design and performance decision. Belco XT garage wrap delivers clean lines and lasting curb appeal while standing up to the everyday impacts of car doors, lawn equipment, and constant exposure near the concrete slab. Unlike brittle fiber cement options or high-maintenance traditional wood species like SYP, Belco XT is preservative-treated throughout with Wolman® AG, so even if the paint surface is scratched or nicked, the fibers remain protected against rot and decay. The result is a reliable, polished frame that minimizes ongoing maintenance.
Quick Tip: – When installing garage door trim, maintain a small gap between the bottom edge of the trim and the concrete slab. This prevents moisture absorption and swelling, ensuring long-term performance and protecting the clean, finished appearance of the garage opening.
Corner Trim
Decorative trim to help protect the corners where siding joints come together. Innovative one-piece installation, adding structural integrity, and eliminating typical horizontal butt joint issues, as well as the need for vertical corner seams. Typically 2×4
Belco XT Corner Trim is a true “One and Done” solution. Its one-piece design eliminates the seams, gaps, and multi-board assemblies that make corners a notorious failure point. Available in 10′ and 20′ lengths, it installs in half the time of traditional methods, resists wind-driven rain and moisture intrusion, and delivers a seamless, professional finish from ground to gable. It protects against rot even in hard-to-reach second-story corners, cutting down on callbacks and maintenance headaches. For inside corner applications where siding meets, Belco XT Inside Corner Trim provides the same single-piece simplicity. It creates a clean, uniform joint while eliminating the need for pieced-together solutions that can shift or separate over time.
Quick Tip: – Use 20′ one-piece corner boards on multi-story builds. They eliminate horizontal butt joints, which are often skipped in flashing and are prone to leaks. This provides superior moisture defense and a clean, uninterrupted line that homeowners love and dealers can stand behind.
Drip Edge
Trim strip under the roof edge installed on the bargeboard (gable end fascia) to protect against moisture intrusion. The drip edge is cap flashed to protect against rot while providing a standoff, so that the water that runs off the gable end does not leak down over the barge, causing unsightly streaking and potentially leading to rot. Typically 1×2, 1×3
Drip edge may feel negligible when considering all of the exterior trim applications, but it plays an outsized role in protecting gable ends and roof systems. Installed at the top of the bargeboard, Belco drip edge creates an essential gap for flashing while shielding trim from wind-driven rain and runoff. Unlike fiber cement or OSB, which are brittle or prone to swelling, Belco’s preservative-treated wood resists decay, holds paint beautifully, and integrates seamlessly with standard flashing systems. The result is a clean roofline detail that prevents streaking, pests, and rot for years to come.
Quick Tip: – Pair Belco XT drip edge with properly installed cap flashing. This combination closes the gap against moisture intrusion, giving dealers fewer warranty claims and builders lasting protection at one of the roofline’s most vulnerable points.
Frieze Board
(TOP OF WALL) Trim member connecting the siding with the soffit. Enhances architectural detailing and provides a finished look to the exterior by trimming out and hiding the cut edge of the siding at the top of the wall. Typically 1×4
Frieze boards may sit quietly at the top of the wall, but they do some of the hardest work in exterior applications, closing the gap between siding and soffit while keeping out moisture, pests, and wind air intrusion. Sharp square edges create crisp shadow lines for a clean architectural finish that can be custom finished onsite to enhance visual impact. Unlike cedar or composites that can swell, fade, or dent, Belco’s treated SPF trim resists rot and reduces maintenance over time, and the likelihood of profit-eating callbacks.
Quick Tip: – Flash above horizontal frieze boards before installation. This simple step ensures protection against seeping water behind siding cutlines.
Door Trim
Decorative trim for exterior doors to enhance visual interest, curb appeal, and style. Maximizes style continuity while also providing important functionality such as weather and pest resistance.
Entry doors set the tone for a home, and the trim that frames them needs to look sharp, have staying power in high-traffic use, and install seamlessly. Belco XT door trim is milled for consistency, so builders can expect beautiful lines, smooth edges, and reliable paint adhesion from board to board. Its lightweight SPF substrate makes handling and cutting easy on-site, while the factory primer ensures a professional finish with minimal prep. The result: faster installs, cleaner details, and doorways that make a lasting impression without adding time or complexity.
Quick Tip: – Angle-cut the bottom edges of exterior door trim at 45° to shed water away from the threshold. Sealing cuts with primer preserves the protective barrier and extends the life of the installation.
Batten
Narrow strips of wood used to cover joints or as decorative vertical members over plywood or wide boards. Adds texture and visual interest while providing additional weatherproofing. Typically 1×2, 1×3
Board-and-batten is back in a big way, and Belco makes it easier to deliver the look without the headaches. Lightweight, straight, and preservative-treated, they install cleanly over siding joints to provide both depth and weather resistance. Unlike brittle fiber cement or premium-priced cedar, Belco XT offers builders a cost-effective way to achieve modern farmhouse style or classic vertical accents with the confidence of long-term performance.
Quick Tip: – When installing battens over horizontal trim, leave a 3/8” gap above band boards and avoid caulking between them. This allows proper water drainage and prevents moisture buildup that could compromise the siding system.
Belly Band
The nontechnical term for decorative cladding that runs horizontally around a house or building. It usually wraps around the building at the height of the first or second floor and is typically used as a breakpoint between two different styles of siding, ie, lap and shake. Typically 2×10, 2×12
Belly bands are the trim detail that ties an elevation together, creating a clean horizontal break between siding styles while also bridging differences in thickness. Belco XT belly band trim arrives in extended lengths up to 20′ and a thicker profile than fiber cement, making it the reliable choice for spanning wide runs without extra joints. Kiln-dried, preservative-treated, and factory-primed, Belco outperforms cedar, OSB, and composites, delivering architectural presence with long-term protection against rot, swelling, and mildew.
Quick Tip: – Install belly bands with sloped Z-flashing above. This prevents water from pooling on the board face and, paired with Belco’s preservative treatment, ensures a crisp visual break that endures.
Balustrade
A barrier system of form and function, consisting of two key components: rails and balusters. Rails are the horizontal structural elements that provide stability and support, while balusters are the vertical members that create a secure, stylish barrier. The balustrade enhances the visual appeal and architectural style of stairs, balconies, and porches. Sizes for balusters and rails vary in range, typically 2×2 to 2×4.
A well-designed balustrade provides a safety barrier (especially on upper-story balconies) and adds architectural interest, framing outdoor living spaces in ways that make them more distinct and inviting. With Belco XT rails and balusters, builders can achieve both classic vertical rail designs and modern horizontal styles, as shown here. Each option offers a unique personality to the porch while maintaining the structural integrity and long-term durability Belco is known for. Belco XT rails and balusters offer a balance of strength and design flair that elevates the curb appeal on any residential project.
Quick Tip: – Experiment with rail and baluster orientation to achieve distinctive porch styles without changing materials. For example, vertical balusters highlight traditional architecture, while horizontal layouts create a sleek, contemporary aesthetic.
Window Sill
Decorative trim elements for windows that provide a surface for water runoff. Maximizes style continuity while providing weather resistance and structural integrity. Typically 2×3
Window sills are another vulnerable point on a home’s exterior, often exposed to standing water and constant runoff. Belco XT sill stock is engineered to solve these challenges with a precisely milled profile that combines reliability with refined appearance. The 15-degree bevel sheds water away from the structure, while an underside relief cut prevents moisture from wicking into the trim below. The result is a sill that resists rot and enhances architectural detail with clean, professional lines.
Quick Tip: – Fasten sill stock by nailing into the beveled face at a slight angle into the framing member, alternating between the face and underside at 16″ on center. This technique secures the sill while preserving its ability to shed water effectively.
Window Trim
Decorative trim elements for windows to add visual interest through increased textures and shadow lines. Enhances the aesthetic appeal and functionality of windows. Typically 1×4, 5/4×4
Window trim may seem like a small detail, but it’s one of the most powerful tools for shaping a home’s character. Whether used to create bold frames, subtle slimline accents, or contrasting color borders, Belco XT trim gives builders the design freedom to match any architectural style. Beyond aesthetics, every piece is preservative-treated and factory-primed, so the beauty of those details endures through harsh weather, seasonal shifts, and years of homeowner use.
Quick Tip: – Reduce waste on multi-window installations by planning cuts with Belco’s Window Trim Cutlist Optimizer. Longer 14–20′ lengths minimize splices, while optimized cut patterns save labor, material, and money on every job.
Porch Posts
Glulam wood, fully laminated structural column for porches and decks. Manufactured to eliminate the need for additional wrapping, substantially cutting labor costs. Typically 6×6
Belco XT® Posts are engineered for strength, designed for beauty, and built to save time and cost on every job. Unlike solid-sawn timber that can twist or require costly wrapping, Belco’s glulam construction delivers straighter, lighter, and stronger posts that install efficiently and perform reliably. Pre-primed and preservative-treated, they arrive ready for paint with no extra prep or wrap, cutting labor in half compared to multi-piece systems. The result is a post that lowers total installed cost while delivering the load-bearing capacity builders need and the long-term curb appeal homeowners deserve.
Quick Tip: – For added versatility, choose Belco XT® Posts with a built-in conduit chase. They make routing porch lighting or electrical features simple, saving labor and preserving the clean look of the column.
Soffit
A decorative covering consisting of interlocked T&G boards to add depth and texture to exterior ceilings, eaves, and overhangs. Used to dress up the underside of the rafter tails so the future homeowner is not stuck looking at the painted underside of the roof sheeting. Typically 1×6
Belco T&G brings natural pine beauty and versatile design potential to soffits and beyond. With a smooth, reversible face and tight-knot grain, it delivers warmth and architectural interest whether used overhead on porch ceilings and eaves or indoors on accent walls and wainscoting. Lightweight and bundled for convenience, Belco T&G installs quickly with a secure tongue-and-groove fit, giving builders a cost-effective way to add refined detail and homeowners a custom look that lasts.
Quick Tip: – For soffit installs, blind nail at an angle through the tongue to keep fasteners hidden and maintain a clean finish. Pair with proper ventilation to preserve airflow and prevent moisture buildup in covered outdoor spaces.
