Question 1

How long does this cladding last?

Accepted Answer

Thermo Scandinavian Pine is rated Class 2 durable with an expected service life of 20–30+ years in exterior applications. This performance is backed by a 20-year manufacturer's residential warranty against rot and decay, giving you lasting confidence in your investment.

Question 2

Does this product require maintenance?

Accepted Answer

Thermo Scandinavian Pine is virtually maintenance-free from a structural standpoint—it will not rot, warp, or cup. If left unfinished, the wood will naturally weather to an elegant silver-gray patina. To preserve the original warm honey-gold tone, a UV-protective oil can be applied every 1–2 years.

Question 3

Is this product suitable for exterior use?

Accepted Answer

Absolutely. The thermal modification process at 212 °C fundamentally changes the wood's cell structure, dramatically reducing moisture absorption and making it highly resistant to rot and insects. Thermo Scandinavian Pine is engineered specifically for demanding exterior applications such as cladding, siding, and soffits.

Question 4

What is the difference between the two length options?

Accepted Answer

The Random Length Mix (6'-14') ships immediately from stock and includes a variety of lengths for a natural, staggered installation. Custom Specified Lengths allow you to order exact lengths tailored to your project, with a typical lead time of 4–6 weeks.

Question 5

Is this product safe and non-toxic?

Accepted Answer

Yes. Thermo Scandinavian Pine is modified using only heat and steam—no chemicals, preservatives, or toxic treatments of any kind. It is 100 % safe for interior and exterior use, including around children, pets, and food-contact areas.
