All forms have 70mm of EPS either side of the concrete core.
Contractor4	Core :102mm	Restricted to intenal walls, or in conjunction with full brick wall
	Overall: 242mm
Contractor6	Core: 158mm	Our most widely used core size, used for most houses and flats, meets Part E for party walls, and can be used in partly submerged builds.
	Overall: 298mm
Contractor8	Core: 203mm	Used for basements and for increased noise performance
	Overall: 343mm
Contractor10	Core: 254mm	Used for unpropped retaining walls
	Overall: 394mm
Notes	Acutal performance will depend on the finish used, for more information see our chart "U value by finish".
	When used to build basement walls 2.5m deep (or more) the U value improves to 0.15-0.16w/m2k

The Logix Eco range

U = 0.21 - 0.19w/m2k
Made using Neopor (grey) EPS bead with FRA (fire retardant additive).

Eco6	Core: 158mm	Our most widely used core size, used for most houses and flats, meets Part E for party walls, and can be used in partly submerged builds.
	Overall: 298mm
Notes	other sizes are available by special arrangement only.
	Acutal performance will depend on the finished used, for more information see our chart "U value by finish".

The Logix XRV range 

U = 0.17 - 0.11w/m2k
Made using Neopor (grey) EPS bead with FRA (fire retardant additive).
The inner EPS is 70mm thick, while the outer EPS can be varied to alter the  value.
The first number in the code refers to the core size, while the 2nd number refers to the outer foam thickness.
XRV6-4	Outer EPS: 102mm	U = 0.17w/m2k
	Overall:  330mm
XRV6-5	Outer EPS: 127mm	U = 0.15w/m2k              (The minimum required for Passivhaus)
