Daehyup Spray S

Fire Protection

Fire protection is probably the insulation form that raises the highest demands on the material and the
    method of application. Steel construction is one of the areas where Spray is of great advantage.

No mechanical fastenings are needed and there are no seams that will have a negative impact
    on the fire resistance. No other tested system, where only rock wool and polymer binder and used,
    exists on the world market today.

Spray S, density 150㎏/㎥ is grey in its natural colour and has the same qualities as Spray G in sound
    absorption, condensation control, and thermal insulation, but is used where a fire rating is needed.

Spray S is used as fire protection in almost any application : such as in steel construction, offshore
    installation, lead-through in fire walls and turbine insulation, for ceilings, duct insulation, and angles
    of roofs. But especially in the offshore environment Spray is well ahead.

Spray S has been approved as fire insulation, A-60 Deck and Bulkhead, by Det Norske Veritas(DNV),
    IMO Resolution A.517(13).

Spray is tested according to IMO/ISO-regulations which have tougher criteria than BS/ASTM.
