Earthwool Dritherm Cavity Slab 32 Ultimate

DriTherm Cavity Slabs
For the thermal insulation of masonry cavity external walls, either partially filling or fully filling the cavity.

Description
DriTherm Cavity Slabs are semi-rigid or rigid slabs of non-combustible, glass mineral wool with a water-repellent additive. They are 455mm wide to suit standard vertical wall tie spacings, ensuring a closed joint with adjacent slabs.

DriTherm Cavity Slab 37 Standard has a thermal conductivity ranging from 0.035 to 0.037 WmK
DriTherm Cavity Slab 34 Super has a thermal conductivity of 0.034 WmK
DriTherm Cavity Slab 32 Ultimate has a thermal conductivity of 0.032 WmK
