We carefully match films to glass using LLumar’s compatibility guidelines to avoid risky pairings. That said, window manufacturer warranties are issued by the window maker/installer—not by Peak—and terms vary by brand, age, and glass construction. For definitive coverage details, please check with the dealer who sold/installed your windows or the window manufacturer.
Good to have for your estimate: brand, year installed, glass type (tempered/annealed/IGU), and whether/where a Low-E coating is present.
(Note: LLumar residential films carry a limited lifetime manufacturer warranty for the film itself; ask us for details.)
