Treatments

Most people leave their timber to go the traditional silver-grey in the sun. We recommend talking to www.wood-finishes-direct.com if you would like to treat your timber. If you do decide to treat your timber, it needs to be treated all the way round including the ends to prevent moisture getting in at all.

To get a price, you can type in how many square metres of cladding you need. It's very easy to work out.

We're going to work out the total area of one side of a building, then subtract the windows and doors, then add 10% extra for wastage.

1) For each wall that you’re cladding, measure the full width and the height in metres to work out the total area.

In this (expertly designed) example, the frontage is 9 metres wide and 4.7 metres high. 9 x 4.7 gives a total 42.3 square metres.

How to measure For Cladding Step 1

Total area of frontage = 9 * 4.7 = 42.3 square metres

2) Work out the area of the doors and windows

In this house front there are four windows and a door. Measure the width and height of each window and door, then add the areas together:

How to measure For Cladding Step 2

  • Window 1: 1.9 x 1.2m = 2.28 square metres
  • Window 2: 1.2 x 1.2m = 1.44 square metres
  • Window 3: 1.2 x 1.2m = 1.44 square metres
  • Window 4: 1.9 x 1.2m = 2.28 square metres
  • Door: 1.0m x 2.0m = 2.00 square metres

Total area of windows and doors = 9.44 square metres

3) Subtract the area of the doors and windows from the total area of the wall.

We now have our total area (42.3 square metres) and the total area of the doors and the windows (9.44 square metres). Because we don't want cladding to cover the windows and door, we take the door and window area away from the total area.

Total area to clad = 42.3 – 9.44 = 32.86 square metres to clad

4) Add at least 10% spare for wastage

We recommend ordering at LEAST 10% more cladding than you've measured for to account for the required cutting and shaping.

32.86 square metres + 10% = 36.146 square metres. In this case, we'd round it up to 37 square metres.

Total to order = 37 square metres

Do the same for any other sides of the building, add them together and you'll have your grand total.

When working with set lengths it is important to take into account any waste.

This is easy enough if you can select the exact length you need, however, that isn’t always the case which is where you need to take a bit more care when ordering. If you can select the length you want, our website will automatically work out the number of pieces required, otherwise you will have to work out the additional quantity.

So for example, if you are cladding a wall that is 2.3m high and 6m wide (as seen in the below image) with vertical cladding, you may want set lengths so that you have no vertical joins.

Set length Example Wall

To work out your coverage you will need to do the quick calculation to work out your area:

Square Metre Calc

Height x Width = Square Metres
2.3 x 6 = 13.8m2

Once we have this we can work out your linear meters (Our website will let you enter either square or lineal metres as a quantity and will automatically work out the other for you).

The linear metres required depends on the profile, so for this example we are using IWC1 which has a 135mm face.

Linear Metre Calc

Square Metres / Face (in metres) = Linear Metres
13.8 / 0.135 = 102.22

Set length Example Quantity

This is where we need to work out what quantity you actually need. For a 2.3m length in this example, the closest set length is 2.44m so to get a price the iWood website will do the following calculation.

Number of Pieces Calc

Linear Metres / Length of Pieces (Rounded to next highest number) = Number of Pieces
102.22 / 2.44 = 41.89 – Rounded to 42

Now to work out the actual number of pieces we need, we need to change that calculation to this:

Linear Metres / Length Wanted = Actual Number of Pieces required
102.22 / 2.3 = 44.44 – Rounded to 45

So, with the first calculation we would have been 3 pieces short.

So now we need to work out the actual number of lineal metres we need in order to not be short on order. So now we need to rework out our quantity.

Number of pieces needed * Length of Pieces = Actual Quantity
45 * 2.44 = 109.8

Enter the new Actual Quantity into the linear metres and you will get the correct price.

We do recommend adding 10% waste on all cladding orders just to account for any cutting that needs to be done on site.

Wastage Calc

Qty (either square metres or linear metres) * 1.1 = total with 10% waste.
