Synthetic teak deck

Cooler, lighter, greener

Dek-King 2G is a premium synthetic decking which is a third cooler and lighter than its traditional synthetic counterpart.

In an article for IBI, Dek-King Joint Managing Director Chris Berry said: “Our premium 2G decking may look the same and has retained its non-slip properties, but you can really feel the difference under foot. It’s 30% cooler, making it ideally suited to warmer climates where the warmth of a deck has previously been an issue.

“We’ve also reduced the weight by 32%, which equates to greater efficiency while under sail or power, which can lead to faster performance and less fuel consumption.”

Manufactured using state-of-the-art technology, the new material is also more environmentally friendly as it contains less PVC, uses a phthalate free plasticiser and is REACH compliant whilst remaining 100% recyclable.

2G – The Facts

 

MaterialSpecific Heat per volume unit*Thermal conductivity**
1G Material (Standard Synthetic Teak)1.825 MJ/m3K0.194 W/mK
2G Material1.245 MJ/m3K0.143 W/mK

The 2G sample tested has a lower thermal conductivity, 26.3% less than the 1G sample.  This is as expected when comparing the densities of each product, with the lower density 2G resulting in a lower thermal conductivity. Similarly, the 2G sample gave a 31.8% reduction in Specific Heat per volume.

* Definition of Specific Heat Capacity per volume unit: The heat required to raise the temperature of the volume unit of a material by one degree.  The higher the value, the easier it is to transport heat through the material. For any given “material”, the heat capacity of a body is directly proportional to the amount of “material” it contains (measured in terms of mass volume). Doubling the amount of “material” in a body doubles its heat capacity.

** Definition of Thermal Conductivity: The rate at which heat passes through a specified material, expressed as the amount of heat that flows per unit time through a unit area with a temperature gradient of one degree per unit distance. Heat transfer occurs at a higher rate across materials of high thermal conductivity than across materials of low thermal conductivity.
