Product Description
Treatment

British Larch Board on Board Cladding

British Larch is a hard wearing, durable softwood with excellent rot resistance. Often compared to its Siberian cousin - Siberian Larch, British Larch is pale pink in colour and contains knots with dark circles as opposed to the pale yellow colour and reddish grey knots of Siberian Larch.

Due to its high knot content, British Larch board on board cladding works well in a traditional setting. It is also freshly cut from the log so, as well as complete flexibility in size, it is also very cost effective.

Typically, our customers opt to leave their British Larch Board on Board cladding untreated as it is classed as moderately durable suggesting at least a 15 year service life. Leaving it untreated will cause the boards to go that traditional silver colour from exposure to the sun.

What are the Options for British Larch Board on Board Cladding?

We supply our board on board cladding planed all round and offer two different profiles:

IWC28 – Traditional board on board cladding, sometimes referred to as Yorkshire cladding is a series of overlapping boards. This style is comprised of PAR square boards fixed onto the battens spaced 29mm apart, there is then another layer placed over that gap, these boards in turn overlap by 20mm either side. This creates depth in the panel and a complete panel to protect the structure beneath from the elements. It’s important with this style of cladding not to fix the top layer of boards to the batten through the boards on the back layer.

IWC29 – Is similar to IWC28 but uses narrower boards, leaving a 5mm gap between the back boards with a thinner strip to span the gap.

Board on board cladding is only suitable for vertical fitting. Our website calculators will factor in board overlap to calculate a price.

What is the difference between British Larch and Siberian Larch board on board cladding?

Due to its harsh growing conditions, Siberian Larch grows very slowly and is very resistant to frost. This slow growth also makes it quite hardy making it ideal for high traffic areas. In cladding though, the extra resilience isn’t as desirable, particularly in the UK climate which makes the lower price tag on British Larch much more attractive.

British Larch shines when a good quality softwood cladding product is needed but within a tight budget as it will perform much better than standard redwood and whitewood cladding that you will find on the shelves of your local builders merchant.

Is Larch Good for Cladding?

Homegrown larch is an excellent cladding timber, it is highly durable due to its high resin content with many knots that have the dark surrounding circle typical of Larch. We have previously supplied British Larch to clad a complete building see photos here: https://www.iwood.co.uk/customer-gallery/28.

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.
