Lava Rock Fire Media – 25 lb Bag
Enhance your fire feature with natural lava rock fire media, a durable and heat resistant material commonly used in fire pits and fireplaces. Lava rock creates a natural base that improves airflow around the burner while adding depth and texture to the flame presentation.
Formed from natural volcanic stone, lava rock withstands extreme temperatures without cracking or breaking down. Its porous structure helps distribute heat evenly and supports stable flame performance in both propane and natural gas fire features.
Simply pour the lava rock into the burner pan or fire pit basin to create a clean, natural looking fire bed.
