Thornhill questions
Does security film work on Thornhill's original 1960s-70s windows?
Yes — it bonds to the interior face of the original glass and holds it together if struck, resisting forced entry without requiring a window replacement.
My neighbour built a taller second storey — will frosted film help?
Yes. Frosted film holds its privacy day and night, which matters once a window that used to face open space now faces a rebuilt, taller neighbouring house.
