AJ Manufacturing, LLC is a family owned business that manufactures safe, high quality floor protection for wood and pellet stoves. From humble beginnings, AJ has grown to be the premier manufacturer of floor protectors for hearth products in the Eastern United States. Today, AJ offers a broad selection of products to suit every taste and budget. Every AJ product is first quality, regardless of price. Durability is ensured by the use of high quality materials including the tile and/or stone surface materials, steel and/or wood components, and the appropriate substrate (the material under the finished surface). The thin-set mortar, used to adhere the tile or stone to the substrate, is specially modified to ensure a very strong, permanent bond. Every AJ floor protector carries a 3 year limited warranty.
