JET Lichtbandzargensystem Typ K

Continuous rooflight kerb system, Type K | VELUX Commercial

Safe and secure roof connection, even for narrower continuous rooflights


The Model K continuous rooflight kerb system not only provides you with a permanent safe andsecure roof membrane connection, but also has numerous additional advantages. The kerb system isstructurally pre-dimensioned and, in addition to the luminous efficacy, also looks attractive due to the optional colour coating in RAL 9002.


The rock wool thermal insulation up to 80mm thick is perfectly tailored to the kerb geometry, and therefore offers excellent thermal insulation values. The continuous rooflight can also be assembled temporarily independently from the roof membrane connection by utilising the OPTIMAL connection rail.


In addition, the Model K continuous rooflight kerb system fulfils the conditions from DIN 18234-3 on the kerb head without any additional on-site measures, and guarantees additional safetyfor the second drainage level due to the outwardly sloping 8° inclination of the kerb head.
