Expansion joints in Fascia Board

[cdh]

Hi

I am in the process of fitting new fascia board. I have done one side of the house, but have recently read that there should be a 5mm expansion joint.

Should this be at both ends of the board and is it critical that this is followed. The sections that I have done so far only have the joint at one end.

Thanks

What colour are you fitting?

The make is freefoam, 17mm thick and white.

Hi

Does anyone know if the colour makes a difference?

Wanted to try and get cracking tomorrow on the other side.

Thanks

Sorry you fell off the radar there for a bit!

Anyway, darker colours are more prone to movement but i have not witnessed any problems with white thus far. We haven't used expansion joints in the past and have not noticed any prob's.

Wisdom would say leave a gap though......

If its a cold day leave 5mm at one end and 4mm at either end for woodgrains/blackgrains.

All the creaking and cracking on a hot day is usaully done by the guttering
