In 2009, UL adopted UL 1618-2009 as the standard for Wall Protectors, Floor Protectors and Hearth Extensions. AJ, and other manufacturers of hearth protectors, worked closely with UL to develop this standard. The result is a system that simplifies matching the appropriate floor protection to the hearth appliance. Floor protectors are divided into two basic categories – Type 1 Ember Protection and Type 2 Thermal protection.

Many modern hearth appliances do not require thermal protection (heat resistance) on the floor. These products may specify a non-combustible material or ember protection. A Type 1 floor protector provides protection from accidental ash or ember spillage. A Type 1 protector has a thermal resistance of R = 0.

If any amount of thermal resistance is required by your appliance, then Type 2 Thermal Protection is necessary. The appliance may express the requirement as a “k” factor, an “R” value, or an equivalency in thicknesses of millboard. AJ Type 2 floor protectors have a minimum R value of R = 1.1. R values up to R = 10 are available. Check with your hearth retailer to ensure you choose a floor protector that meets or exceeds the appliance specifications.
