Comparative test for the three leaders of synthetic teak decking 

The use of synthetic teak in marine decking is quickly and successfully replacing that of the natural wood.

There are many companies producing this material today but only three are the most popular and the most widespread ones. We therefore decided to compare the best of the current production in a no-holds-barred test.

synthetic teak comparative deck, aesteticsSo, we contacted the three companies and asked for some samples. The only request we made was that the synthetic teak to be sent to us was their best product and the one most similar to natural teak.

This way, we had the opportunity to test and compare, in a very simple way, the features that most affect the choice of synthetic teak (all our staff was involved in the test and everyone was asked to express his own opinion).

The synthetic teak we tested is, in alphabetical order, the Flexiteek, the Permateek and the Plasdeck.

Here’s what we found out:

Synthetic teak : aesthetics and touch feeling

First of all, we decided to analyze the aesthetic appearance and therefore the element that makes both boat owners and their guests fall in love at first sight.

Of course, it’s a subjective yet important choice since, once chosen, the synthetic teak has the implicit characteristic of maintening the same appearance over years.

More specifically, Flexiteek shows veins and shades that make it, in a natural way, very similar to real wood. Its colour is light biscuit.

Plasdeck, too, is synthetic teak comparative deck, touchbiscuit-colored but its finishes are less processed, which makes it look a little “flatter” and less natural.

The Permateek Classic, instead, is very different from the others since its darker colour makes it more similar to aged or oil-processed wood. However, the typical nuances of wood are absent. The veins in relief, reproduced during the processing phase, are instead very marked and visible throughout the panel. But they don’t seem natural at all.

Another difference between the three products concerns the width of slats and seams. Flexiteek’s ones are narrower, slimmer and more elegant while the other two are wider.

As for the tactile sensation, we noticed that there’s a big difference between the three products. Permateek is made of harder and rougher plastic, Flexiteek is softer while Plasdeck is somewhere in between.

In our opinion, this test concludes with the following ranking: 1 Flexiteek – 2 Plasdeck – 3 Permateek

Sun exposure

synthetic teak comparative deck, temperatureNow, it’s time consider another important aspect, that is the temperature that synthetic teak reaches when it is exposed to the sun. We tested this aspect in a July sunny day (with external temperature of about 30 degrees) where we left the three teak panels exposed to the sun for some hours. At regular intervals, we measured the temperature with an infrared thermometer. The test started at lunch time, that is the hottest time of the day.

After more than one hour of sun exposure, our teak synthetic panels reached the maximum temperature peak. The Permateek was the hottest one, with a temperature of 60.8 degrees, followed by the Flexiteek with a temperature of 57.3 degres and the Plasdeck with 53.5 degrees.

Yes, it’s true, the synthetic teak comparative deck, heat retentionPermateek is also the darkest one but, at the end of the day and even after having remained in the shadow for more than one hour, it was still the hottest one (36.8°), which suggests a longer heat retaining effect.

The other two panels, instead, turned cold more quickly and, after having remained in shadow for one hour and despite the difference in their peak, they reached the same temperature of 34.8 degrees.

In addition to thermometric measurements, we also tested the sensation of warmth transmitted by the materials, walking barefoot on the different teak panels. This step resulted in a further confirmation and a surprise.

The Permateek was the hottest and the contact with the sole of our foot confirmed that. Moreover, the sensation of warmth remained on the foot for some minutes, which confirmed the excellent warmth retention capacity of the material.

Flexiteek, instead, while not registering the lowest surface temperature, when it came into a prolonged contact with our foot, proved to have the lowest warmth retention capacity. This suggests that the material composition (Flexiteek G2 patent) ensures greater heat dispersion.

In conclusion, this second test concludes with Plasdeck and Flexiteek coming joint first and Permateek in last place.

Weight

We calculated the weight of our panels on a m2 basis. This time, Flexiteek proved to be the best product. This is an important aspect to take into account when dealing with a boat. The following table shows the overall weight of teak decking on a 13-meter sailboat.

Sample cm cm cm² weight in kg weight/m²
covered surface
kg in total
Flexiteek 40 40.2 1,608 0.1608 0.721 4.484 30 134.515 Flexiteek
Permateek 39.5 40 1,580 0.158 0.848 5.367 30 161.013 Permateek
Plasdeck 41 41.5 1,701.5 0.17015 1.003 5.895 30 176.844 Plasdeck

Let’s take into consideration a sailboat, especially a performing one. A lower weight on the deck not only contributes to reduce the overall weight but also and above all reduces the weight positioned above the waterline. This way, the centre of gravity of the boat remains lower, which contributes to reduce heeling when sailing while improving performance.

This is also true for motorboats that, as you know, have wider decks and therefore need more square meters of synthetic teak. On these yachts, the main difference lies in comfort and not in performance. Especially if these boats are equipped with a flybridge: a lower weight on this means lower rolling for the yacht itself.

Ranking: 1 Flexiteek – 2 Permateek – 3 Plasdeck

Resistance to dirt

The main goal of synthetic teak comparative deck, resistance to dirtour test was to see the real reaction of the three materials to the contamination caused by the overthrow of some of the most common staining products, those that pass on the deck day by day: coffee, wine, vinegar and sunscreen.

For the first part of our test, we spilled some staining substances and we left them on the teak surface for about one minute; then, we removed everything with what is the most used method on each boat, ie water.

The result is the same for all the three products: stains were removed with a simple cleaning carried out with the hands under the flowing water.

The three products came joint first

Damage resistance

synthetic teak comparative deck, damageIn this respect, too, the three products are almost the same. All the materials passed our crash tests (we dropped anything on our samples, even very heavy items) and no damage was registered.

Things changed when we tried to pierce the panels with our scissors and screwdrivers in order to simulate the most common deck accidents. This time, no sample passed the test: all of them let themselves be pierced ( the Permateek with a little bit of difficulty). This is maybe inevitable with a plastic material that, after all, is not so different from natural wood that, unlike synthetic teak, cannot be repaired if not with a long work.

The three products came joint first

Grip

In order to test grip, synthetic teak comparative deck, gripwe decided to carry out a very simple test: to create an inclined plane where to put our teak samples with a sailing shoe containing a weight on it. The maximum inclination reached by the shoe without slipping was very similar for all materials. We tried many times and we reached a 36-degree inclination: an excellent goal, beyond which no material produced enough friction for the shoe to remain glued to the surface.

To the touch, the Permateek proved to be the roughest material, capable of the best grip thanks to its more market veins.

Ranking: 1 Permateek – pari merito Flexiteek e Plasdeck

The back of panels, predisposition to gluing

synthetic teak comparative deck, back surfaceThe three materials have a much different side B.

Flexiteek is highly processed and shows a series of grooves (another patent of the company) that facilitate gluing without bubbles and “slipping” effects. Permateek has a micro-perforated bottom while Plasdeck is the smoothest one.

For obvious reasons of simplicity and installation quality, this chapter concludes with this final ranking: 1 Flexiteek – 2 Permateek – 3 Plasdeck

Conclusions

Rankings speak for themselves and, even if individual differences are not big, Flexiteek is undoubtedly the absolute winner.

It proved to be multi-purpose, highly efficient in all respects and even the most similar one to natural wood.

However, it is also true that boat owners, or better their personal tastes, have the final say. These synthetic teak panels are offered for sale in many colour options, so you can choose the colour combination you like the most or that best matches your boat.

We thank all three manufacturers that, as proof of their good faith, accepted the test without hesitation.

  1. Thanks for this article, very interesting!
    any chance to add to the test a piece of real teak?
    Also, quite important, particularly on racing boats, the abrasion test. Ropes and sailbags dragged on the foredeck could leave marks…

    thank you

  2. As a certified synthetic teak installer that has installed all three products and watched them weather over several years, Permateek looks newer longer. It is slightly heavier and stiffer but goes down straighter.
    Flexiteek is challenging to keep the lines straight upon installation.
    I have found the 2G has a tendency to mold on the surface where the others do not.
    The grooved back of Flexiteek is only good on paper! When installed over aggressive non-skid, the grooved back may allow for water penetration. This can damage the gel coat and allow moisture to enter the coring.
    Your test only showed the appearance and
    Temperature concerns while there are many aspects to consider.
    If Permateek submitted a similar color to the others, the temperature difference is insignificant.
    All surfaces are sanded when manufactured. And again when fabricated.
    The texture can be anything from smooth to “hairy”.
    Yes, Flexiteek is a good product but it’s not as good as you tauted it to be.
    Real world testing is suggested in the future.

  3. DRB Marine used to dabble in Flexiteek before switching over to Dek-King, which had excellent feedback all over the US and beyond. They have now been acquired by Flexiteek, which is a compliment on the standard of quality manufacturing performed at their U.K. location.
    Indeed, Flexiteek is now produced fully at this factory with glowing success!
    As my Company handles the Importing for the Americas, let’s remember that DRB chose ‘not’ to go with an existing factory that had worked well for the last three years, and continues to increase the quality control levels in order to maintain the #1 status.
    Don produces excellent work, just a shame he chose to jump ship for reasons not related to the quality!
