Thermowood Rainshield Cladding

Thermowood Rainshield

Thermowood Rainshield cladding is a contemporary product which combines machined smoothness with traditional feather edge overlapping. Although it isn’t overlapped quite as much as what feather edge is, the Rainshield profile we supply has the overlap built into it with the chamfer on both faces for the top and bottom of the board. This design is to help water run of the face of the timber naturally while allowing air to circulate behind (which is always helped by a breathable membrane as well).

The Thermowood iWood supplies is a Scandanavian Pine which has been heat treated so that the most amount of moisture as possible has been removed from the timber. This improves durability and stability. The third benefit of this treatment is that is dries up any resin and tannin in the wood so helps to prevent it from rotting. Due to this process the characteristics of the wood are changes so that it struggles to take on moisture, this makes it ideal for external use, and means you don’t need to seal it with a paint or oil.

If you do wish to paint the timber or preserve the colour, you can get a wide range of treatments at wood finishes direct. Thermowood will take the paint well, so you will get the finish you desire.

We provide Thermowood Rainscreen cladding in our IWC8 profile in a Sawfalling grade. This grade of wood does contain a fair number of knots, most of which will be sound. It is worth accounting for the dead knots that may appear in the timber though, so we recommend ordering an extra 10% so you can cut around these knots.

A Suitable Alternative to Siberian Larch

With current supplies of Siberian Larch being difficult int eh current climate, we have been looking for a suitable wood to fill the void and Thermowood fits the bill perfectly. It is highly durable with little maintenance and take s a paint really well. Making it a solid choice for any cladding project you have.

Our Thermowood is available as PEFC certified because it is sourced from sustainable sources.

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.
