HPC Deck Insulation Kit

Locating any kind fire pit on wooden or composite decking used to be a definite no-no!
For wood-burning fire pits, that is very much still the case. Unfortunately, spark guards do not stop 100% of sparks and embers, so it is just too risky.

Gas fire pits, on the other hand, do not spit out red hot projectiles, but some essential precautions must be taken when building a gas fire pit on a deck.

Gas Fire Pit On Decking

The temperature inside the structure of a gas fire pit can be very high, and this is where the risk lies when the fire pit is built on decking.

The first thing to check is that your deck is strong enough to support the weight of your fire pit! Some form of reinforcement may be necessary.

Your hard pipe gas feed should come up from underneath the deck and be located in the center of the fire pit structures footprint.


To correctly use the HPC Deck Insulation Kit, the manufacturer recommends that you cover the entire base area of the fire pit structure with a layer of paver blocks (1″ min. thickness) commonly found at your local builder’s store.

The insulation kit should then be laid over the entire area of the paver blocks, with the heat reflective silver side up and the gas pipe stub sticking up above the center’s layer.

The specially engineered thermal barrier made from flameproof volcanic rock fiber ( Basalt ) blocks the transmission heat.
Providing it is installed following the manufacturers’ instructions, temperatures underneath the Insulation Kit are kept within the safety zone, and way below the range that can damage your decking.

The HPC Deck Insulation Kit cuts easily with a utility knife making installation simplicity itself. There are two standard sizes of the sheet to choose from, the smaller kit is 19.5 x 19.5 inches, and the larger one is 39.5 x 39.5 inches ( 1 sq. meter ).  For larger fire pits, use multiple pieces of the Basalt Insulation Kit and always follow the manufacturers’ instructions.
