Decking with a differenceThe Hybrid decking board from Duraflex is no ordinary deck board. Made with both PVC and woodthis product provides you with their unique properties rolled into one single base material with thelow maintenance and durability of PVC and the appearance and strength of wood.
The result of this is a decking product of extremely high quality, which exhibits excellent slipresistant properties tested against the Health and Safety Executive’s grading system, as well asexcellent resistance to organic growth matter.
An accelerated weathering test further strengthens the view that Hybrid decking provides theperfect performance criteria.
Hybrid is a material that is strong, resilient, water resistant, low maintenance, slip resistant,combined with an option for an attractive, ribbed or brushed finish, as well as a range of colours tosuit your particular application.

Hybrid DeckingMarine and CommercialIn 2007, Duraflex was approached by a number of players in the Decking and Wood Plastic Compositeindustry with a request to enter the arena in order to bring sustainability of performance and supplyto this emerging but fragmented market.
Duraflex Marine and Commercial Decking is the result of three years' research, development andproduct evaluation.
During the development cycle, Duraflex evaluated products and materials currently on the market, inthe extensive Research and Development facilities at Masco Headquarters in Michigan.
Concerns were expressed with regard to the variability found with some recycled materials. Unable tosatisfy ourselves that consistent product quality could be achieved with the samples tested, Duraflexmade the decision to work exclusively with virgin polymers.
Investigations led us to the conclusion that raw material selection was a vital consideration.
Discussions ensued with potential customers and further concerns were raised that when in use, someof the composites were deflecting more than anticipated, with this deflection becoming permanentwith time. We therefore, determined that flexural modulus and bend strength were the key designparameters.
It is widely reported that Water Absorption leads to a reduction in flexural modulus, and thereforebecomes the third most important parameter. Our research laboratory performed a 14-day immersiontest of decking material, results as follows:
Typical Recycled Duraflex Decking Polyethylene Decking
Flexural Modulus MPa 6000 - 7000 2500 - 3000
Bend Strength MPa 64 20 - 35
Water Absorption (%) 1 - 5% 10 - 20%
Having established the core physical properties, we then focused on performance, in particular slipresistance, growth of organic matter on the deck surface and weatherability.
Immersion tests showed that the Duraflex deck exhibited the least organic growth when comparedwith typical Recycled Polyethylene Deck filled with wood flour or rice hulls, thus improving the slipresistance in service.
The form and finish of Duraflex decking exhibits excellent slip resistance when tested against theHealth and Safety Executive's published grading system.
Accelerated weathering results further reinforced the view that virgin PVC / WPC gives excellentperformance, as would be anticipated, with the long history of PVC-U as an exterior product.
When compared with hollow or solid recycled polyethylene decking, the Duraflex Deck outperformedall samples tested in terms of △E and LAB colour shift.

Solid vs Hollow Boards
Duraflex Composite Decking | Technical Guide11
It has been reported that solid boards perform better than hollow boards.
It should be noted though, the case is made "based on boards of similar dimension and materialmake up".
The real debate should be based on the results achieved with firstly the "base material" andsecondly the board itself, irrespective of design or material.
Facts resulting from laboratory analysis comparing board for board, show significant differences inperformance.
Internal and external sources were used to conduct a range of tests, coupled with a comparison ofpublished data.

Water Absorption*: The above test results are based on a 24-hour test. In our laboratory weextended the water immersion test with the following findings after 14 days:
Duraflex Board 4.5%Hollow Recycled PE with Rice Hulls 9.5% Hollow Recycled PE with Woodflour 17% Solid Recycled PE with Woodflour 20%
The argument of hollow vs solid has far less relevance than material selection. The choice betweenrecycled polyethylene as a feedstock or PVC, should be made on performance criteria. If we considerthe Flexural Modulus, Bend Strength, Burning Behaviour and Tensile Creep (a critical structural testrarely given for polyethylene), then PVC based WPC becomes an obvious choice.

Many misconceptions exist in terms of the environmental credentials of PVC-U
Less than 50% of the feed stock used in the manufacture of PVC is oil-based derivatives, unlike otherbulk polymers, such as Low Density Polyethylene and High Density Polyethylene, where oilderivatives are the major ingredient.
PVC primary feed stocks are Common Salt (57%) and Ethylene (43%). In more recent times, thereliance on oil derived ethylene has been further reduced with the production of ethylene fromsugar.
With respect to PVC/WPC, the ethylene requirement is further reduced by the addition of 50% woodflour. In this regard, Duraflex has made a decision to use wood flour that carries PEFC certification,further enhancing the sustainability credentials.
The recycling of WPC/PVC can be handled either directly through Duraflex, taking the benefit of ourin-house recycling facility or by using one of our partner members of Recovinyl, who segregatematerial types on receipt and recycle accordingly.
Currently, very little WPC is entering the recycle market, however, as volumes grow, the industry willinevitably expand its recycling capabilities. The market requirement for recycled quality WPC is fargreater than the current availability.
On a more general note with regard to the environmental credentials, Duraflex have exceededgovernment energy saving targets for the 10th consecutive year, which has resulted in a surplus ofover 9,000 tonnes of CO2 (Carbon Credits).
