Solutions for comfort insulation

  1. Comfort insulation can be used alone where there is no other demand for the deck and bulkhead.
  2. Comfort insulation can also be used together with fire insulation or sound insulation.

When the minimum insulation thickness has been found for protecting against sound or fire, the thermal transmission (U-value) of this material can be calculated from the λ-value. If a higher insulation level is requested the construction can be improved by adding an extra layer of a lower density product.
In all cases of insulation towards cold temperatures the wool must always be covered by a vapour tight surface. This surface can be aluminium foil or another kind of vapour barrier. The gaps should be tightly sealed with alu tape.
When adding additional insulation to a fire construction it should be documented and approved by the local surveyor.

Floor connection

When making a surface towards the exterior it is necessary to end the insulation 50 mm above the floor. This to make sure that condensate from the bulkhead can be drained away.

All ROCKWOOL SeaRox products fulfil the IMO rules of 'non combustibility' and 'low flame spread'. Besides this the products have excellent water repellent properties which are also important as thermal insulation is often placed directly up against the outer construction with changing temperatures.
