Question 1

How long does this cladding last?

Accepted Answer

Thermo Ash is Class 1 durable—the highest durability classification—with an expected service life of 25–50+ years. This performance is backed by a 20-year manufacturer's residential warranty against rot and decay.

Question 2

Does it require maintenance?

Accepted Answer

If left untreated, it will age into a beautiful silver-gray patina. To maintain the original deep chocolate-brown "Crème Brûlée" tones, apply a UV-protective oil once a year.

Question 3

Is it resistant to termites?

Accepted Answer

Yes. The thermal modification process removes the natural sugars (hemicellulose) that insects feed on, making it naturally pest-resistant without toxic chemicals.

Question 4

Can it be used in fire-sensitive areas?

Accepted Answer

Yes, it holds a Class B Fire Resistance rating, suitable for premium residential and commercial projects.
