Heat Treated Aspen Panel 15×120 STS

Heat treated aspen panel is an excellent choice for saunas and bathrooms, but it also works beautifully in other areas of the home and interior design. The STS panel features a modern, sharp-edged profile and is very easy to install on both walls and ceilings by following our sauna panel installation instructions.

This durable, thermally treated aspen panel is knot-free and resin-free, and it doesn’t become hot, even in intense sauna steam. Alongside alder, aspen is one of the absolute best choices for sauna paneling. Heat treated aspen panels can be installed on walls and ceilings to bring warmth and deep elegance to your space. For a cohesive look, pair it with sauna benches made from durable thermally treated aspen.

A Sustainable and Environmentally Friendly Choice

Heat treatment of wood involves only heat and steam, making the process completely eco-friendly and chemical-free. It significantly improves the durability of the wood. Heat treated aspen retains its dimensions better than untreated wood and gains a noble hardwood-like surface along with a pleasant natural scent. It can be used untreated in its natural wood state or surface treated as desired. Treating the panel with paraffin oil enhances its rich dark tone, protects the wood, and makes cleaning easier.

Heat treated wood belongs to the best indoor air quality class, M1.
