A blowtorch flame being applied to a piece of decking material, causing it to smoke and char.

The video begins with a close-up of a blowtorch flame applied to a piece of light-colored composite decking material, which begins to smoke and char. This is followed by a shot of a man, Geoff Van, identified as a firefighter and owner of Van's Construction. The video then shows a side-by-side comparison of three different decking materials (Class A, Class B, Class C) being subjected to flames from blowtorches. The Class A material (TimberTech Advanced PVC Vintage) shows minimal damage and smoke, while Class B (Capped Wood-Plastic Composite) shows more significant charring, and Class C (Mineral-Based Composite) burns intensely and begins to disintegrate. The video concludes with shots of a finished deck and the TimberTech logo.
