Shade Sail Fabric Heat Resistance

Our shade fabric is made of extruded high density polyethylene fibers, commonly known as HDPE, which is a plastic polymer. This means that exposure to excessive heat can melt or burn the material. As such, we discourage placing shade sails over or near heat sources like grills or fire pits. Beyond heat, you want to avoid allowing smoke from fires to gather under the sail or discolor it.

As noted on our fabric page, our fabric is fire rated as a “Class I/A Fire Retardant”, and has fairly low flammability and flame spread indexes. See the fabric data sheet for specifications.
