Description
Upgrade your chimney system with the DuraVent DuraPlus 7" Square Ceiling Support Box. This essential component is meticulously engineered to elevate safety and performance. Say goodbye to worries about overheating and creosote fires, and step into a world of superior chimney efficiency.
DuraPlus is your trusted solution for maintaining a cool exterior while generating a hot draft within. Its innovative design includes two insulating layers – a refractory blanket and an airspace – ensuring consistent heat distribution and eliminating those troublesome hot spots common in traditional insulation. Even in the event of a creosote fire, the compressible blanket insulation allows the chimney liner to expand safely, preventing damage to your chimney and your home.
Crafted to endure continuous operation at temperatures of up to 1000°F, DuraPlus surpasses the stringent HT requirements of the UL standard. It has been rigorously tested, enduring one hour at 1400°F and three ten-minute chimney fire tests at a blistering 2100°F. With DuraPlus, you can trust in its exceptional fire-safe design, safeguarding both your chimney and your home.
