ABOUT SUNDI WPC
WHAT IS THE SUNDI WPC(WOOD PLASTIC COMPOSITE) MADE OF?
SUNDI WPC(Wood Plastic Composite) is a green energy saving & environmental protection product, which is mixed the wood flour and high performance modified plastics with special additives, and extruded by special equipment and our patented molds to make our high performance composite materials.
SUNDI wood plastic composite decking is made of 50% recycled wood fiber – 40% recycled HDPE & 10% additives.
WHAT IS THE ADVANTAGES OF SUNDI COMPOSITE DECKING THAN WOOD?
SUNDI composite decking offers the natural appearance and aesthetic appeal of wood with the durability and resilience of plastic.
Unlike timber, SUNDI composite decking never need to be stained, oiled or painted. It doesn’t split, warp and is also resistant to termites. Kind to be bare feet, it won’t splinter and is slip resistant. Being made from 95% recycled materials makes, it is an eco-friendly alternative to wood.
DOES SUNDI 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 perish, rot, split and warp. So in the long run, you’ll be saving money.
WHAT’S THE DIFFERENCE BETWEEN SUNDI TRADITONAL AND CAPPED COMPOSITE DECKING?
SUNDI traditional composite decking are made from a single mold of wood and plastic composite material, making them a long-life alternative to timber decking. But some of these products developed mold/mildew, and/or prone to staining.
SUNDI capped composite decking has a protective outer layer that is extruded to the traditional composite material core during the manufacturing process. This encapsulates the product and provides added protection against the elements and everyday living. SUNDI capped composite decking has all the great features of traditional composite decking, with the added benefits of improved stain, mold and fade resistance. It’s easy to understand why more and more homeowners are making the smart move from wood decking to composite decking.
WHAT’S THE DIFFERENCE BETWEEN SUNDI HOLLOW AND SOLID CORE BOARDS?
SUNDI solid board looks more like lumber. Some homeowners prefer solid composite decking because they look more like the real lumber traditionally used for decking. Their deck board ends are more authentic looking. And solid boards, because of their denser construction, are particularly strong. So, if you want your deck to look like solid wood with high stability, you might prefer solid composite boards.
SUNDI hollow board is much lighter than the same size solid board. This makes them easier to work with. Building your own deck is a labor-intensive process. So, If you want to work with lighter-weight materials, you could benefit from hollow boards, which weigh considerably less than their solid counterparts. You might have an easier time transporting and positioning the boards, as well.
What the weather temperature is suitable to use our COMPOSITE MATERIALS?
It’s from -40°c to 60°c.
DOES SUNDI COMPOSITE MATERIAL EXPAND AND CONTRACT?
All composite materials will expand and contract with the changing temperature. It will expand during the hotter season and contract during the colder times. This expansion and contraction is a natural characteristic.
The rate of expansion and contraction is depended on the difference between the temperature during installation and your local area’s maximum temperature. Correct board spacing is essential to ensure adequate space for normal expansion and contraction. Depending on the weather and temperature conditions on installation day, the amount of normal expansion and contraction of the boards will vary.
In general, allow 3/16 inch to 1/4-inch gaps between boards to allow for expansion and contraction as well as to let dirt and water flow away naturally.
WILL COLOR FADE BECAUSE OF EXPOSURE TO THE SUN?
For SUNDI traditional composite products, composite products will fade a little after it is exposed to the sun and undergoes the weather. During the first 3 months, the color may fade a little with a approximated percentage of 5% to 10%, this will not affect the overall effect. After that, the color will stay in a stable level through the lifetime of the product.
For SUNDI capped composite decking has protective shell technology which provides far superior fade and stain resistance, and in turn will not fade whatsoever.
ARE SUNDI COMPOSITE DECKING RESISTANT TO STAINING?
SUNDI traditional composite decking board is uncapped, meaning is not fully resistant to spot stains. If spillage or stain occurs, we recommend treating immediately with absorbent cloths, following up with a general clean with warm and soapy water.
SUNDI capped composite decking board is capped in a polymer shell that forms a protective shield around the core. This provides excellent stain resistance and an easy-clean surface.
DOES SUNDI WPC DECKING GET HOTTER THAN WOODEN DECKING UNDER THE SUN?
On a hot day with a blazing sun, nearly any outdoor materials’ surface will get uncomfortably hot. Lighter colored boards tend to be slightly cooler than darked composite decking boards. In extensive studies, it has been found that the color of the composite decking boards, regardless if it’s made of wood-plastic composite or wood is the most significant factor in the “heat retention” of the board. In these studies, pressure-treated wood stained the same color as ours are actually hotter than SUNDI composite decking boards in the same test conditions.
CAN I INSTALL THE DECKING IMMEDIATELY WHEN RECEIVED THE PRODUCTS?
When received your WPC decking boards, we recommend you allow them several days to adjust to your local temperature and conditions before starting working. We do not recommend installing your deck in cold weather.
DOES WPC PRODUCT NEED THE GOOD VENTILATION AND DRAINAGE?
Yes, like timber, it s important to provide adequate ventilation and drainage to ensure WPC decking is able to dry out after being wet Lack of ventilation and drainage can cause the products to swell over time Should carefully check the installation guide before installation.
DO I NEED SPECIAL EQUIPMENT OR TOOLS TO INSTALL SUNDI COMPOSITE DECKING?
You don’t need special tools to install composite decking, using the same tools you would use to install the timber decking. You need standard woodworking tools for cutting and building. Since composite decking materials cut just like wood, you can use a circular saw or a miter saw for installation. This type of decking also accepts nails and screws like real wood.
CAN COMPOSITE DECKING BE INSTALLED TO BOTH TIMBER AND METAL FRAMING SYSTEMS?
Yes! SUNDI composite decking can be installed on our composite joist, and it is possible to install our board onto timber or metal subframe, customers can choice what you want. The clip fastener is used on all systems but the screw is different. Please specify to your supplier whether you are using composite, timber or metal framing.
ARE THERE TOXIC PROBLEMS THE CONSUMER SHOULD BE AWARE OF?
There are no toxic chemicals or preservatives involved in the manufacturing of WPC Decking.
HOW DO I MAINTAIN/CLEAN SUNDI COMPOSITE DECKING?
All exterior building materials require cleaning and SUNDI decking is no different. To maintain the beauty and clean of your SUNDI decking, a little care and cleaning goes a long way. We recommend a semi-annual cleaning with a composite deck cleaner, soap and water cleaning or a gentle pressure washing will do the trick. Using a pressure washer(maximum 1200 psi) is an effective way of cleaning any surface dirt and debris from the deck boards, applying the spray a minimum of 30cm from the deck surface will ensure this process doesn’t damage the boards.
DO SUNDI WPC PRODUCTS NEED PAINTING OR STAINING?
SUNDI composite products are designed to be a low-maintenance alternative to wood decking. As the difference with the wood, SUNDI composite products delivers its own line of vibrant colors that do not need to be stained or painted.
