secondary Glazing

If the secondary glazing panels are large and of the lift-off type they are a bugger to remove for cleaning due to the weight. I have used the clear acrylic sheet type; they are lighter but easily scratched.

B&Q?

But they won't work as well for sound insulation.

We used those for a time but couldn't get a good enough seal to prevent dirt and tiny (very tiny) insects getting into the void.

Same here, we could not even get rid of the draughts. They are gone now replaced by sealed units with rubber seals to prevent draughts.
