XO/CW (T&G)

XO/CW (T&G)

Partial Fill Cavity Walls

XO/CW (T&G) is an innovative partial fill
wall insulation system incorporating robust
facings, engineered jointing details,
performed corners and a certified lambda
of 0.021 W/mK.

This lower lambda improves U-Values and
meets Future Homes standards, proving an
excellent choice for passive and low energy
builds. XO/CW (T&G) can achieve a passive
U-Value of 0.15 W/m2K in a traditional cavity
wall. When building with XO/CW (T&G),
a residual cavity is maintained, offering
excellent protection against wind driven rain.
