Full-fill systems not only provide the best U-value to wall width ratio but are also the lowest in cost. Even with dense concrete blocks it is possible to achieve very high thermal performance in a manageable wall width.
Masonry cavity walls built using our DriTherm solutions do not require cavity barriers, and full-fill systems can be installed in all types of buildings across the built environment.
DriTherm Cavity Slabs are a range of lightweight semi rigid or rigid slabs of glass mineral wool with a water repellent additive. They are manufactured to fit between wall ties at standard vertical spacings.
