The Dark Room Dr 120 has a thermal film finish that offers 97% thermal protection.

The Dark Room Grow Room is the most advanced grow tent available. It is the first line of grow tents to utilize thermal film on the interior, which is highly reflective, waterproof and extremely insulative (offering 97% reflection and thermal protection). This film is also non-toxic and won’t release any harmful gasses that can damage sensitive plants. The Dark Room also utilizes innovative, adjustable Dual-Sock Ports that enable the grower to attach equipment or ducting to both sides of the tent while maintaining a lightproof environment, and doesn’t require the use of clamps or tools.
