When it comes to your home's safety and warmth, there's no room for compromise. Introducing the DuraVent DuraPlus Attic Insulation Shield, your steadfast guardian against potential chimney hazards. This product has been engineered to meet not just industry standards, but the highest expectations of homeowners like you.

Inside this unassuming collar and base assembly lies a world of innovation. DuraPlus is more than just a shield; it's a guardian of your family's well-being. With a triple-wall construction that includes refractory blanket insulation and a ventilated air space, this shield keeps your chimney cool on the outside while delivering a hot draft on the inside. The result? Enhanced stove efficiency and a fire-safe design that safeguards both your chimney and your cherished home.

But what truly sets DuraPlus apart is its ability to withstand the harshest conditions. Tested to endure continuous operation at 1000°F flue gas temperatures, it goes above and beyond with UL standard compliance. With a track record of enduring an hour at 1400°F and not one, but three ten-minute chimney fire tests at 2100°F, you can rest assured that DuraPlus is built to perform when it matters most.

You must also take photos of all sides of the box and send them to us within 2 days. If there are no damages visible before opening the box, you must note "subject to further inspection may contain concealed damage". If you notice any damage after receiving the delivery, do not throw the box away, and contact us with the photos. After we receive information from you about the refused delivery or concealed damage, we immediately initiate a claim with the shipping company or with the manufacturer. After the claim is fully processed, we ship all replacements at absolutely no cost to you.
