How To Calculate How Much Composite Slatted Cladding Material You Need

When it comes to installing EcoScape cladding, often the first and hardest step is figuring out exactly the quantities of each component you need. We’re here to make this job easier with this handy guide! 

You can either use detailed plans to calculate how much material you’ll need, or you can use the following steps and equations to find your final figures. 

H2 Step 1: Measure the Length of Trims 

The first step is to work out which type of trims you require and how many metres of each you will need. We can supply two trim styles – end trims and corner trims. Both trims are 3.6m long, so you should divide the total length required by that number. 

For example, if the total length required for corner trims is 50m and for end trims 14m, the equations will look like the following: 

50/3.6 = 13.8 (rounded up to 14) corner trims required. 

14/3.6 = 3.8 (rounded up to 4) end trims needed. 

Step 2: Measure the m2 Area of Boards 

To work out how many total cladding boards you need, you’ll need to measure the total area to be covered in m2, and multiply this by 8.93. You would then divide this number by 3600mm (3.6m) to work out the total number of individual boards you need. 

For example, if your total m2 area is 55m2, your equation would look like the following: 

55 x 8.93 = 491.15 

491.15/3.6 = 136.43 (rounded up to 137) boards. 

Total Materials 

Using the measurements above, the total cladding materials needed would be 

  • 137 Cladding Boards 
  • 14 Corner Trim Boards 
  • 4 End Trim Boards 

This isn’t the extent of the equipment you will need for fitting cladding boards, however, you will also need to consider cladding clips and screws and the tools you will need – to find out more about the tools and fixings you need in your kit, take a look at this handy guide. 

It is also worth noting that if you are laying your boards vertically, there may be additional waste depending on the wall height. You can use any offcuts above or below windows and above doors to minimise waste product.
