Maintaining your Cladding

Discover all of our tips on how to maintain your timber cladding here, where we answer your frequently asked questions!

Do I need to maintain ThermoWood?

Whether you chose to maintain your ThermoWood cladding is purely down to personal preference. It is not essential for maintaining it’s lifespan. The techniques outlines would just be for cosmetic purposes. The only thing that we would advise doing, is cleaning your boards periodically. Especially if your cladding is near the ground or prone to being splashed with mud. To clean your natural ThermoWood boards, you can use a jet wash or a hose (please note that when cleaning charred cladding, you should use a sponge and water instead).

If you do not want your natural ThermoWood cladding to weather to a grey hue, you could apply an oil which would prevent this weathering.

The advantage of thermally modified hardwoods is that you don’t need to do anything with it. You can simply install your cladding and leave it. Your decision to maintain your timber is purely down to personal choice, since weathering does not affect the durability of the material.

Does all timber fade to a grey colour?

At some point, as with all natural timbers, the material will fade to a silvery-grey colour. Some timber species’ fade quicker than others. Generally, a lighter coloured timber will take a lot longer to fade then a darker timber. This is simply as a result of UV oxidisation on the surface of the timber. If you scratch that surface, you would find the original colour underneath. Weathering is not something that you need to worry about in terms if the materials’ durability. It is purely an aesthetic factor.

How long does timber cladding last?

Our ThermoWood cladding offers a lifespan of 30+ years. Your timber cladding should last this long however, it depends on how well your material is installed. Softwood materials would hold a slightly shorter lifespan. However, this is all down to the exposure that the materials endure. If your project is located on the coast and is constantly being battered by salt spray, then the timber will weather quicker compared to an area that endures less exposure to the elements. Ultimately, if your project has been properly constructed, it will offer a good lifespan.

Can cladding be painted?

You can apply a range of finishes to your timber cladding. For example, we have a ThermoChar® range that offers different charred finishes. We also have an AtelierClad® range which offers different colour coated finishes. So ultimately, yes, you can apply a coating to your cladding, but it is all down to the type of material that you use. If you coat a cheap softwood, it will expand and contract, and then the paint will crack since the paint will not move with the changes in the board. The most important thing to consider in the UK is to have a very stable and durable timber, which will not expand, contract, twist and warp. These properties will offer you the opportunity to incorporate a painted surface on a board that will last a long time.
