Capped composite decking is known for its low maintenance requirements, as it doesn’t require the regular staining, sealing, or painting that traditional wood decks often do. It’s a popular choice for homeowners seeking a durable, long-lasting, and attractive decking option that can withstand various weather conditions.
PROTECTIVE SHIELD
Capped composite decking refers to the protective outer layer or cap that is typically made of a high-performance polymer. This cap shields all four sides around its inner WPC core from the elements, making the decking even more resistant to staining, fading, and general wear and tear.
COMPOSITE CORE
The core is from Bongywood wood plastic composite materials, which uses recycled plastic and recycled wood.

Nevitably weathered with splits, peel and cracks
Wood enventually resuly in deforestation
Capped Composite Decking FAQs
What is capped composite decking?
Capped composite is also called co-extrusion WPC. it has an advanced tough plastic shield encasing all four sides around its inner WPC core, which provides added protection against the elements and everyday living.
What is the difference between capped and traditional uncapped composite decking?
The main difference is that capped composite decking has a plastic cap or shell that encases the composite core. While the cap provides added protection against the elements and everyday living, so capped composite decking claims to more durable and has better mold, stain and fade resistance than uncapped composite decking. To lean more please review our Composite Vs. Capped Composite Decking page.
What is the main benefit of 4-sided capping vs. 3-sided?
4-sided capping ensures the entire board, including the bottom and the grooves, is protected from moisture. This prevents “cupping” or warping caused by moisture absorption from the underside of the deck.
Why is Bongywood Capped Composite Decking better than wood?
Bongywood capped composite decking is more durable, requires less maintenance, and is resistant to issues like rot, insects, and splintering when compared to traditional wood decking, and never needs staining or painting. What’s more, Bongywood composite decking is made from 95% recycled materials, that is an eco-friendly decking choice you can feel great about. To lean more please review our IS COMPOSITE DECKING VS. WOOD DECKING: WHICH IS THE BETTER CHOICE? page.
Does Bongywood Capped Composite Decking cost more than treated wood?
In the short term, composite decking may be more expensive to manufacture, but it’s a more sustainable solution in the mid to long term. You will end up saving money each year due to the maintenance requirements of timber, which is more susceptible to termites, rot, split and warp. So, in the long run, you’ll be saving money.
Can capped composite decking get too hot in the sun?
Capped composite decking can get warm in direct sunlight, but it generally doesn’t become as scorching hot as some traditional wood decks. Choosing lighter-colored decking can help reduce heat absorption.
Is Bongywood Capped Composite Decking suitable for all climates?
Bongywood Capped composite decking is suitable for various climates, but it’s particularly popular in regions with extreme weather conditions due to its resistance to moisture, mold, and temperature fluctuations.
Are there any drawbacks to capped composite decking?
While it has many benefits, capped composite decking can be more expensive upfront compared to wood. Additionally, it can expand and contract with temperature changes, so proper installation is crucial.
Is co-extrusion decking slippery when wet?
No. Our boards are engineered with an anti-slip texture, making them safe for poolside installations and rainy climates.
Is Bongywood Capped Composite Decking environmentally friendly?
Bongywood capped composite decking use recycled materials and have a long lifespan, reducing waste and the demand for new resources. Their durability and low maintenance also contribute to sustainability by reducing the need for replacements and frequent maintenance, making them a more environmentally responsible choice compared to traditional wood decking.
What maintenance is required for capped composite decking?
Bongywood capped composite decking requires minimal maintenance. Regular cleaning with soap and water is usually enough to keep it looking great. Unlike wood, it doesn’t need staining or sealing. To lean more please review our Is Composite Decking Really Maintenance Free? page.
Can you install capped composite decking yourself, or is professional installation recommended?
Many homeowners choose to install capped composite decking themselves, especially if they have some DIY experience, and our Installation Guide provide details. However, professional installation is also an option for those who prefer it.
