With such a wide variety of charred timber cladding available, it can be a little confusing as to which is best for you and why. There are many things to consider before purchasing charred cladding and so today we are going to be answering some of the most commonly asked questions about it.

1) How long will my charred timber cladding last?

The length of time that your charred timber will last will depend on what type of timber it is. Some types of charred timber cladding can last for 50+ years. This is made possible due to the specific way in which the charring is carried out, as it creates a protective layer of carbon during the process of charring.

Generally speaking, the heavier the charring the longer it will last. This is because of the way that wood naturally weathers over time. The thinner the depth of the charring the thinner the protective top layer will be, exposing the sound timber below to the damaging effects of weathering, rot and insects. Timber with a thicker depth of charring creates a thicker and more protective top layer and as such will last longer.

2) How to seal charred wood

We have put a lot of research and development into sealing our charred wood and we manufacture specific finishing products depending on the timber and final finish to maximise the protection given. These are our trade secrets so we can’t reveal them to you but rest assured that when purchasing charred timber from Exterior Solutions, your timber will be well-protected.

3) Does charred wood rot?

Charred wood is extremely resilient to rot as well as insect damage. In fact, the charring process on some woods even makes it resistant to fire to Euro Class B. This is because the process of charring the wood draws out moisture from within and leaves a natural protective chemical compound on the surface.

All wood, regardless of the type or finish applied will eventually succumb to rot. Wood is a product of nature and as such will eventually return to nature. However, the harder the timber, the more resistant to rot it will be and the longer it will last – in some cases 50 years or more.

4) What wood can you char?

Some timbers accept the charring process better than others.  Things that affect the char include the timber species, moisture/sap content, how it has been cut, air moisture and temperature.
