I have a grade II 16th century timber frame farm house in Essex. Our windows are historic oak framed with leaded lights, we have fitted secondary glazing internally using Perspex and magnetic tape. The secondary glazing is almost invisible, caused no damage to frames or window surrounds. It is easy to remove if required with no damage to anything. It cuts drafts & noise considerably
