Charred Effect Cladding: A Burn-Free Alternative

Some people love the look of burnt timber but not the mess or the cost. Charred effect cladding copies the finish without burning the board. This post explains how it differs from true charred wood. If you want the real thing, read our charred cladding guide

What “charred effect” means

A charred effect board is not burnt. The dark, textured surface is created by finishing, in the same way a painted board is coloured. That is the key difference from shou sugi ban, where the surface itself is charred.

What we sell: SertiWOOD DragonWOOD

On our site the charred effect product is SertiWOOD DragonWOOD, a 19x146mm tongue and groove board. The product page describes it as follows:

• Charcoal black, RAL 9005.
• Treated with preservative and painted in controlled factory conditions.
• A heated roller embossed charred, burnt or scorched effect pattern.
• No extra staining needed.
• Tongue and groove on all four edges, installed horizontally or vertically.
• Suitable for interior and exterior cladding, and custom furniture projects.
• A finish warranty is mentioned on the page. Ask us for the terms.

The product page lists 2.4m and 3.0m lengths, and a sample piece is available.

DragonWOOD or real charred cladding?

The consistency of a factory finish is a plus if you want a uniform wall. Real charring is more variable and many people prefer it for that reason.

The charred product pages carry a notice that the cladding is for non-permanent applications and not certified under CPR 2013 for permanent construction use. DragonWOOD is a different product, but check its status for your project and ask us for its documentation.

Where charred effect cladding suits

Typical uses are:

• Feature walls, inside and out.
• Garden buildings and extensions, subject to your regulations.
• Furniture and joinery, as the page suggests.

If fire performance matters for your building, charred effect does not answer that question by itself. See fire retardant cladding and talk to us.

Installing and finishing

The page says no extra staining is needed. We also list a SertiWOOD black featheredge and DragonWOOD wood finish in our finishes range. Ask us whether it suits your project.

Use stainless fixings appropriate for exterior use, and ask us about the best fixing method for the profile.

Cost

We do not quote prices in this post, but the sample is a cheap way to compare. For the wider cost picture, see charred timber cladding does not need to be expensive.

Choosing between the two

Ask yourself three questions:

1. Do you want variation or consistency? Real charring varies from board to board. A factory finish repeats.
2. Is the project permanent construction? If so, check the certification of whichever product you choose, and ask us for the documents.
3. How will it be maintained? A painted or embossed finish is maintained differently from an oiled charred surface.

Both are legitimate choices. Neither is better in every case. If you are torn, put a sample of each side by side in daylight against your other materials, such as render, brick and window frames.

Trends to watch

Whichever finish you choose, ask for the paperwork behind it: documentation, warranty terms and how the product ages. Compare these across products, including real charred timber.

In December 2025 the government published research on the fire hazards of timber cladding (applies to England). It found that fire-retardant treatment reduces the external fire spread hazard of new timber cladding, but made no statement on aged or weathered cladding, and that slatted configurations showed a greater external fire spread hazard than flat or lapped cladding. It is research intended to inform future guidance, not a change to the rules in itself, so check the current Approved Document B and speak to building control about your project.

If your project is sensitive to fire performance, a finish alone does not settle the question.
