Plastic Shims

I quite often use those, but run out of the smaller sizes first as I tend to use bits of scrap timber for larger gaps... if you want lots of

There'll be a plastic building materials wholesaler on one of the industrial estates. They supply the spacers to double glazing installers along with all the plastic trim pieces.

Google 10mm plastic packers and you get hits like this

I want them for spacing ledger plates away from walls when building decks. Washers are a pain to use. I wanted plastic so they won't rot away.

I know it's not what you were asking for (don't you hate it when people do that? :-) but if you can't get a bucket full of 10mm spacers for reasonable wonga wouldn't suitable sections of PVC cladding do?

(I take it you've asked your local double-glazing fitters?)

In the 'window trade' the spacers they use are referred to as Flat Packers, but only seem to go up to 6mm, as the frames are only supposed to be 10mm smaller than the brick to brick gap, i.e. 5mm per side. It may be worth asking at a local uPVC suppliers if 10mm are available or you could use two
