It depends what insulation value you are after.and what the make up of the house is.

At the mo 90mm eps is popular for its thermal value

Hi Rob,

All depends on what Insulation you want to go for and what U Value you require.

As Dan says 90mm is the most common due to the U Value it will give you.

Is the cavity filled or not?

A 90mm EPS system onto a wall with a filled cavity will give you a U Value of 0.22, a wall with an unfilled cavity will give you a U Value of 0.29

If you need anymore information please let me know
