Guys, thanks for your ongoing assistance...
I find it strange that I saw no lifting before the silicone was installed about 2 weeks ago. The floor had been down for probably 3 weeks prior to this with no bead and I hadn't noticed any lifting throughout that time.
I would agree with foxhole that silicone wouldn't stop expansion if the floor had absolutely nowhere to go but maybe the silicone is strong enough to cause the floor to lift? As said before, I think the only way I'll find out is to score the silicone bead and see if the floor expands into the perimeter gap. If it doesn't solve the problem then its a skirting off to investigate as Ken says.
FYI the floor is on a suspended timber floor not concrete.
