When it comes to heating your home efficiently and safely, the DuraVent DuraPlus Ceiling Support Box is your trusted partner. Crafted to perfection, this ingenious addition to your chimney system redefines stove performance and offers ultimate peace of mind.

Step into a world where fireside coziness meets cutting-edge engineering. Designed to keep cool on the outside while delivering a hot draft within, the DuraPlus Ceiling Support Box elevates stove efficiency to new heights. Say goodbye to heat loss and hello to a snug, warm home.

But it doesn't stop there. Our DuraVent DuraPlus is more than just a chimney component; it's a guardian of fire safety. With a triple-wall construction featuring two insulating layers – a refractory blanket and an insulating air space – this support box ensures your chimney remains in top shape. No more worrying about common hot spots, thanks to our secure insulation that's here to stay. And in the unlikely event of a creosote fire, our compressible blanket insulation allows the chimney liner to expand outwardly, averting potential disasters.

It is very important that you inspect the packaging of your items when they arrive and check if you received all boxes listed on the delivery receipt. If you notice any damage or shortage of packages, you must make note of it on the bill of lading, take pictures, and refuse delivery. Your note should say "refused due to damage". 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.
