PURPOSE: Protects surfaces under fire pit from heat damage created by portable gas & wood burning Fire Pits & Chiminea's.FUNCTION: Place "Deck Defender" under your Fire Pit or Chiminea and burn as usual.OPERATION METHOD: Deck Defender blocks heat by balancing three elements that apply to the principles of radiant heat transfer. 1) High shine metals reflect heat, 2) Aluminum acts as a heat sink, and 3) Multi layered metals with air spaces in between create an insulation effect because air is a poor conductor of heat. NASA uses this principle in insulating space suits & crafts. Simple, lightweight, no moving parts or necessary maintenance.TESTED: It's 100% fire-proof & has been tested to extreme conditions. Fire pits average app. 1,200 degrees F.MATERIALS: Aluminum top plate and lower steel sub-frame operate together in a 2-piece construction.

APPLICATION: Use with standard gas & wood burning Fire Pits & Chiminea's. WARNING: NOT FOR USE with oxygen supplied fires.
