Fire Performance

Dura Deck Resist achieves superior fire resistance to any other co-extruded decking on the market. British Standards and European codes use different grading systems to class fire performance of materials, resulting in confusion for the industry. Dura Deck Resist is designed to cut through the noise. Some competitor composite decking may reach Class B when tested specifically with certain fire rated substrate barriers but fail when following their own install guide (due to lack of airflow).

Dura Decking Resist features a co-extruded 360° outer armour which protects the core of the plank, increasing its defensive properties against fire. Customers can have confidence that Dura Decking Resist has been certified and tested by a UKAS accredited body, satisfying current fire legislation; with testing carried out in an environment to closely resemble that of an actual installation for the avoidance of doubt.

Understanding European classification (BS EN 13501): B fl s1

The standard includes seven classification levels, from A1 to F, with A1 representing the highest level of performance and F representing the lowest level. Dura Decking Resist achieves Class B. The ‘s’ part relates to total smoke propagation, during the first ten minutes of exposure. These determine a ‘smoke’ index which affects visibility in case of a fire. The lower the number the less smoke propagation, s1 representing the highest level of performance.

How Much Do I Need?

We want to ensure that you have all the correct decking boards and fixings to create a beautiful outdoor space. Use our simple Dura Composites online decking calculator to find out the area of your space.


How to Calculate Your Materials

We want to ensure that you have the correct materials to create a beautiful outdoor space.

Please use the information below to calculate the number of decking boards and fixings you will need to complete your project.

Follow this simple two-phase calculation to generate your material quantities!

Calculate the square meterage of your project area.

  1. Measure the length and width of the space you would like to deck and multiply these figures.

For example: 7m x 3m = 21m²

Now calculate the number of Dura Deck Resist boards you require.

  1. Taking the square meter area calculated in step 1, divide this area by 0.55

For example: 21m² ÷ 0.55 = 39 Dura Deck Resist boards. (You may consider adding a board or two for waste (most professionals factor up to 10%))

To calculate fixings, use the following calculation.

Dura Composites recommends 21 clips and 21 screws per square meter.

Fixing clips are sold in boxes of 100 pieces and screws are sold in boxes of 200.

Referring to step 1, multiply your square meterage by 21. Take this answer and then divide by the box quantity for both the Fixing Clips (100pcs) and then Screws (200pcs) to calculate the number of boxes you will require.

For example, for 21m² you will need 5 boxes of Fixing Clips and 3 boxes of Screws.

You will require Start/Stop Clips for your project, however the quantity of these will be dependent on your project design. If you are unfamiliar with using these types of clips, please refer to our Dura Deck Technical Manual.
