All FIBERFRAME windows & doors,
under normal use and service, are warranted to be free from defects in material and workmanship for the lifetime of the lifetime of
the product. The fiber glass is warranted not to corrode, peel, rot, rust, warp, bow, twist or blister. Remember, fiber glass is
used in boats, planes, bridges, and for industrial flooring in highly corrosive atmospheres such as chemical plants. Why?
Because it's practically indestructible. it has a greater tensile strength than wood, vinyl or aluminum. The means if you
could safely stand four elephants on vinyl or 10 on aluminum, you could stand 20 elephants on pultruded fiber glass!
