FirePro® DuctRock® Slab

ROCKWOOL FirePro® DuctRock® Slab is composed of high density, non-combustible stone wool insulation, finished with a high-emissivity black foil facing. FirePro® Glue and Black Aluminium Foil Tape are available for sealing all board joints.

DuctRock slabs are easy to handle, simple to install, and available in three thicknesses. The slabs are installed using stud welded pins, steel washers and FirePro Glue, and can be cut with a hand saw or circular/table saw.

DuctRock® Slab has been tested to the latest harmonized European standard and is capable of achieving a fire resistance up to EI 120, up to two hours’ fire protection for rectangular ventilation and smoke extract ducts and up to one hour fire protection to ducts with a combustible lining (kitchen extract) ducting.

The solution is typically used in commercial and industrial settings where they travel throughout the building passing through fire rated walls and floors.

Insulating ductwork can be beneficial for reducing thermal transmission as well as protecting the structure in the event of a fire which can amount to costly damages. All joints are to be filled with FIREPRO® Glue (see separate product) and held tightly closed.

Features and benefits:

• EI 120 mins on ventilation and smoke.
• Tested on both vertical and horizontal ducts.
• Wide ranging scope for many duct types.
• High quality black foil finish.
• Patented horizontal penetration detail.
