which silicon for sealing round PVC window frame to wood

latecomer

We are cleaning up the bathroom window at the moment and have removed all existing silicon which now obviously needs replaced. I've been looking at all them online but there are a huge variety available, most of which would claim to be suitable. Needs to be suitable for sealing to PVC and wood and be white.

Also need some clear sealant too which is going on wood (round the frame)

Anyone got any recommendations?

This was recommended to me and after a bit of ringing around local merchants found 1 stockist. Silirub 2, has good adhesion and flexible properties. I know they stocked white and clear (oxime).

Heres some technical data

any white mould resistant silicone will be fine.

Thanks guys. Will be needing some sanitary sealant in the near future and hence will see if I can get one suitable for both.

You shouldn't use the same sealant for sanitaryware etc as for window frames. Get the proper stuff for each job. Frame sealant should be one that is a "low modulus" sealant, sanitary sealant is a "high modulus" one. See http://www.thewindowman.co.uk/sealants.htm for a bit of an explanation.

For sanitary sealant i just bought Unibond Anti-mould shower and bathroom sealant - 35 year guarantee. Can't remember what i use for the windows...probably a Unibond product though.
