All siding,soffit and accessories manufactured by Heartland have a Class A fire rating based on ASTM E84 test results.
All siding, soffit and accessories manufactured by Heartland meet specifications in accordance with ASTM D-635 and ASTM E119-88
certification of a fire endurance rating of I hour. Important: Fire Safety Information-When rigid vinyl siding is exposed to significant
heat or flame, the vinyl will soften, sag, melt, or burn, and may thereby expose material underneath. Care must be exercised 'when
selecting underlaying materials because many underlayment materials are made from organic materials that are combustible.You should
ascertain the fire properties of underlayment materials prior to installation. All building materials should be installed in accordance with
local,state and federal building code and fire regulations.
All Heartland siding, soffit and accessories are considered by the maker to be superior products in both performance and weather
resistance.All products are extruded flat and formed immediately after extrusion to insure a uniform product
