Product Details

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 Slabs have a special additive to make the product water repellent and are produced in three grades:

• DriTherm Cavity Slab 37 Standard has a thermal conductivity ranging from 0.035 to 0.037 W/mK

• DriTherm Cavity Slab 34 Super has a thermal conductivity of 0.034 W/mK

DriTherm Cavity Slabs are for the thermal insulation of masonry cavity external walls, either partially filling or fully filling the cavity. They are approved for use in buildings up to 12m high in any exposure zone and for use in multi-storey applications up to 25m in height.
