Caledonian Decking continues to set the standard for the rest of the domestic and commercial industry.

BS7976-2 – The Pendulum Test – for skid resistance and slip potential

Caledonian Decking deckboard demonstrated low slip potential during wet and dry test conditions, when tested using BS7976-2. The test produces a Pendulum Test Value (PTV) and a value above 36 indicates a low slip potential. In wet and dry test conditions, Caledonian Decking deckboard produced PTV’s of 48 and 55 respectively.

What this means to the consumer

The slip resistant qualities of Caledonian Decking mean that owners need not worry about using their deck during, or after, wet weather; something which we are more than familiar with in the UK! Similarly, the slip resistance of Caledonian Decking combines with its water resistant properties to offer a perfect poolside surface which is safe for adults and children alike. Importantly, Caledonian Decking is also ideal for constructing entrance ramps and steps to increase accessibility without compromising on safety or style.

BS EN 660-2 – The Frick-Taber Test – for wear resistance

The Frick-Taber Test, or Volume Loss Method, determines the wear resistance of resilient floor coverings. Wear resistance is determined by the volume of material lost during extreme abrasion tests. Caledonian Decking deckboard demonstrated good wear resistance, recording a volume loss of more than 2mm3 but less than 4mm3. The results are then assessed against the specifications of BS EN 649 – homogeneous and heterogeneous polyvinyl chloride floor coverings.

What this means to the consumer

The impressive durability of Caledonian Decking means that it will look as good as new, even after very heavy commercial or even light industrial use. The remarkable wear resistance means that the wood-grain effect is not lost, nor is the low slip potential. Try as they may, children and animals will not damage the deck as it withstands the rough and tumble of every day living, as well as more special occasions such as garden parties and al fresco lunches.


BS476: Part 7: 1997 – Fire tests on building materials and structures

This test measures the rate and extent of flame spread. Caledonian Decking deckboard was subjected to the fire test, with the grain running both vertically and horizontally. The run of the grain did not affect the performance of the deckboard, and it was awarded with a Class 1 Fire Rating.

What this means to the consumer

The Class 1 Fire Rating offers owners the assurance that it is highly unlikely that a Caledonian Decking deck will ever set alight. Should this happen, the PVC-U will self-extinguish and will not fuel the fire in the same way that wooden decking and fencing would do. Homeowners can barbecue in confidence and commercial users can be sure that their customers are in safe hands on a Caledonian Decking deck.


balustrade load test

BS 6399-1:1996 – Code of practice for dead and imposed loads – Balustrades

For domestic and commercial applications, barriers or balustrades should be installed where there is a difference in ground level greater than 600mm and 380mm respectively. BS 6399-1 tests the suitability of balustrades to prevent people from falling from areas subject to overcrowding e.g. a Caledonian Decking deck. Extreme pressure was exerted at various points on the balustrade, and the sample passed the BS 6399-1 test.

What this means to the consumer

Quite simply, Caledonian Decking balustrades will protect people from falling from the deck. Users can lean on the balustrades without the risk of them breaking or collapsing, and this accreditation will certainly appeal to domestic or park home users who want to keep their children safe when they play outdoors.

Static Load Test on Free Standing Deck Structure

The Static Load Test measured how much static weight a Caledonian Decking deck could withstand until it collapsed. The deck comfortably held six tonnes of static weight, and only collapsed when half of the load was dynamically dropped four times!

What this means to the consumer

This will be music to the ears of commercial customers who will hope for as many people using their Caledonian Decking installation as possible.

Similarly domestic and park home users can safely use heavy garden furniture on the deck, such as tables, chairs, patio heaters and barbecues, to entertain as many friends as they can gather.
