Outdoor living spaces remain sought-after home upgrades, with ever-increasing numbers of homeowners installing backyard patios and decks. Composite decking delivers an ideal blend of beauty, durability, and sustainability. However, consumers looking to build composite decks face a critical decision – should they opt for hollow or solid composite boards?
Key takeaways
- Hollow boards are lighter and budget friendly, while solid boards handle heavy loads better
- Use hidden fasteners and correct joist spacing recommended by the board manufacturer
- Capped composite boards resist stains and fading but still need occasional cleaning
- Compare total project cost, including framing, fasteners, and trim, not just board price
This choice impacts everything from cost efficiency to structural integrity and aesthetic appeal over the lifetime of a deck. By grasping the nuances of hollow and solid composite constructions, homeowners can make informed selections aligned with their budgets and performance expectations.
Hollow Composite Decking – Lightweight Convenience
Hollow composite decking revolutionized the market with its patented production process centering on a voided interior column sandwiched between rigid exterior shells.
This hollow space significantly reduces weight compared to solid wood and composite alternatives, allowing for easier transport and handling. Even full-length 16-foot deck planks can be lifted and fastened into place by homeowners without heavy equipment.
Despite the inner cavity, structural stability and integrity remain superb through the dense bonded outer layers that resist moisture, UV fading, mould, and everyday wear-and-tear.
Hollow composite boards maintain the opulent visual qualities of natural hardwoods with variable grain patterns and rich colouration options from warm chestnuts to coastal greys.
The hollow design utilises fewer raw materials in fabrication, substantially reducing manufacturing costs. This makes quality hollow composite decking boards an excellent value purchase.
Solid Composite Decking – Robust Heavy-Duty Performance
In response to demand for premium decking capabilities, major manufacturers developed non-hollow composite alternatives constructed from advanced polymers and compression moulding technology.
Proprietary solid core boards withstand over 2,000 lbs of distributed weight per square foot, resisting damage from crowds, hot tubs, planters, and storm debris that cause hollow boards to crack or buckle.
Speciality composites like Ecoscape offer structural warranties – lasting up to five times longer before sagging or splintering than cheaper hollow or wood boards.
Capped composites add a protective polymer sleeve around solid cores, shielding the deck from environmental factors like spilled liquids, excess moisture, and tree debris that ruin uncovered boards.
Deep embossing and multi-tonal variegated finishes further enhance solid composite boards with an unmistakably upscale, hand-crafted aesthetic.
Comparing Key Characteristics of Hollow and Solid
When evaluating the superior choice of decking for your particular backyard vision and household needs, critical factors bubble to the surface.
Structural Strength and Durability
Hollow composite decking suffices for most residential settings with periodic rearrangements of outdoor furniture and family gatherings. Solid composite endures practically punishing loads equivalent to commercial flooring – proving the wiser investment for elevated decks, roof gardens, and lively communal spaces.
Aesthetics
Both hollow and solid composites mimic premium hardwoods across a spectrum of graining and rich colour palettes. Solid boards offer more durable protective polymer caps and dimensional designs like deep embossing. But hollow composites still provide pleasing wood-alternative visuals suitable for most homes.
Sustainability
All composite decking contains recycled plastic, wood fibres, and reclaimed content. But due to lighter weight and highly efficient manufacturing, hollow boards utilise fewer overall raw resources. Both varieties ultimately divert waste from landfills and conserve natural forests.
Concluding Thoughts
When planning a new or replacement deck, homeowners must decide between affordable convenience with hollow boards or robust heavy-duty performance from solid composite. Patented hollow fabrication allows for accessible DIY installation and complexity-free upgrades down the road. Meanwhile, solid composites promise enduring structural integrity worthy of oceanfront properties and desert climates.
Take time to accurately evaluate the outdoor space and forecast how your family will utilise it for years to come before committing. Whether you crave a weekend project or a lifelong investment, composite boards now cater to every preference. Your perfect outdoor oasis starts here.
How to Choose Between Hollow and Solid Composite Decking
Start by picturing how you will actually use the deck. A small ground-level deck for a table and a few chairs is a very different job than an raised deck that will host large gatherings, heavy planters, or a hot tub. Matching the board type to your real load and climate is the surest way to avoid regrets.
Next, think about exposure. Decks in full sun can get hot underfoot, and boards in humid or shaded yards face more moisture and mildew pressure. Ask about expansion and contraction too, since composite boards move with temperature and need correct gapping. In areas with harsh winters, freeze and thaw cycles and snow loads are worth factoring in as well, since boards and framing both need to handle seasonal stress without warping or loosening.
Finally, check local building codes and the manufacturer’s installation guide. Some products are rated only for certain joist spacing or uses, and following those rules helps keep any warranty valid. Your local building department can tell you whether a permit is needed, and a qualified deck builder can confirm whether your existing frame is strong enough for the board type you prefer.
- Light patio use: hollow boards are often enough
- Hot tubs, heavy planters, or raised decks: lean toward solid
- Hot climates: consider lighter colors that absorb less heat
- Coastal or humid yards: look for fully capped boards
Budget Factors Beyond the Price per Board
Board price is only part of the story. Deck projects also include framing lumber, hidden fasteners or clips, fascia boards, end caps for hollow profiles, railings, stairs, and labor if you hire an installer. These extras can add up quickly, and prices vary by region and supplier. Hollow profiles also usually need end caps or fascia to hide the open ends, which is an extra line item many people forget to include in early estimates.
Hollow boards typically cost less per foot and are easier to carry, which can reduce labor time. Solid boards usually cost more upfront but may suit projects where durability and load capacity matter most. Get at least two or three written quotes that list materials and labor separately so you can compare fairly.
It also helps to weigh long-term costs. Composite needs no annual staining or sealing, so maintenance savings over the years can offset part of the higher initial price compared with wood. Think about how long you expect to stay in the home, too. If you plan to live there for many years, the lower upkeep and longer service life of a well-built deck can make the overall value easier to justify.
Cleaning and Caring for Composite Boards
Composite boards are low maintenance, not no maintenance. Pollen, leaves, and dirt can collect between boards and hold moisture, which encourages mildew. Sweeping regularly and clearing the gaps with a thin tool keeps water draining freely and boards looking fresh. Trim back overhanging branches where possible, since falling leaves, berries, and sap are some of the most common causes of stains on light-colored boards.
Twice a year, wash the deck with warm water, a mild soap, and a soft-bristle brush, working along the grain. Rinse well. For grease spills from a grill, clean them promptly before they set. Check the manufacturer’s care guide before using a pressure washer, since high pressure or the wrong nozzle can mark some surfaces.
In winter, use a plastic shovel and a de-icing product the manufacturer approves. Metal shovel edges and some rock salts can scratch or discolor boards. Before winter, do a quick inspection for loose boards, raised fasteners, or wobbly railings, and fix small problems early so they do not become safety hazards for kids and guests when the weather warms up again.
- Sweep weekly and clear gaps between boards
- Wash with mild soap twice a year
- Use rugs rated for outdoor decks to avoid trapped moisture
- Avoid metal shovels on snowy days
Frequently Asked Questions
Is hollow composite decking strong enough for a family deck?
For most ground-level family decks with furniture, grills, and gatherings, hollow boards installed on properly spaced joists perform well. They are less suited to very heavy loads like hot tubs or large stone planters. Always follow the manufacturer’s span and fastening guidelines, and ask a builder if you are unsure about your deck’s intended use.
How long does composite decking last?
Quality composite boards often lasts several decades with basic care, and many manufacturers offer long warranties against fading, staining, and structural defects. Lifespan depends on the product, climate, installation quality, and the condition of the framing underneath. Reading the warranty terms carefully tells you what is covered and what maintenance is expected.
Do composite deck boards get hot in the sun?
Yes, composite boards can get noticeably warm in direct summer sun, especially darker colors. Lighter shades and some newer heat-reducing products stay cooler, but none are completely heat-free. Adding shade from a pergola, umbrella, or nearby trees and keeping sandals handy for kids can make a sunny deck more comfortable.
Can I install composite deck boards myself?
Many handy homeowners install composite boards themselves, especially on an existing sound frame. You will need correct joist spacing, the recommended fasteners, and careful gapping for expansion. Raised decks, stairs, and structural changes are more complex and may need permits, so consider hiring a qualified contractor for those parts.
