KLB height offset blocks, thermally insulated

To achieve space heights that deviate from the 25 cm grid, KLB offers thermally insulating, slotted vbl height offset blocks of type SW1 with a height adapted to the flat solid blocks of 124 mm. The length of these blocks corresponds to the standard height blocks with 30 cm thickness = 497 mm, with 36.5 cm thickness = 247 mm. The blocks are manufactured in the strength classes 2 and 4 with the gross density classes 0.45 and 0.60. The coefficient of thermal conductivity matches the SW1 flat blocks with thermal conductivities λ_R = 0.10 W/mK or λ_R = 0.14 W/mK respectively.

These blocks form the upper wall finish for the thermal insulating blocks SW1 or W3 finished with thin-bed or thick-bed joint.
