The “your product” Exclusion Applies if the Product is not Fundamentally Changed

Recently, in Liberty Mut. Fire Ins. Co. v. MI Windows & Doors, Inc. (Fla. 2d DCA 2013), the Court relied on a “your product” exclusion of a CGL policy to partially reverse summary judgment that was entered in favor of insured window and door manufacturer and against insurer.  The court ruled that the exclusion applied since the fact that a third party added transoms to the insured’s sliding glass doors did not fundamentally change the nature and function of the doors, thus the doors remained the insured’s product.
