upvc double glazed window fit

[zena]

I need help with sealing round my double glazed window I put in. It is costly to call someone in so I need to know how is best to fill the gap round the window in the brickwork? expadable foam and sealant? or is there more?

large gaps say 15mm or larger use foam then cover with 30mm plastic trim. remember to only fill 50% depth, let the expansion do the rest. less than 15mm external silicone sealant will do.
