This lower lambda improves U-Values and meets Zero Carbon standards, proving an excellent choice for passive and low energy builds. XO/CW (T+G) partial fill can achieve a passive U-Value of 0.15 W/m2K in a traditional cavity wall. Using XO/CW (T+G) allows the residual cavity to be maintained, offering excellent protection against wind driven rain.
