Description

ROCKWOOL Ablative Coating is used to further improve the fire resistant properties of ROCKWOOL stone wool slabs. The ablative nature of the coating resists flame spread and forms an insulated char which protects the stone wool slab.

The coating is available separately to enable site repairs to Ablative Coated batts that may have been damaged during installation. ROCKWOOL Ablative Coated Batt is intended to act as an air seal barrier to reinstate the fire resistance and acoustic performances of concrete floors, masonry walls and dry wall systems when voids have been created for the passage of services. This includes pipes made of plain or stainless steel, cast iron, copper, polypropylene (PP), high density polythene (HDPE), PVC and ABS along with all sheathed cables up to 80 mm and supported cable bundles up to 100 mm.

The product is a water based coating which may be brush or spray applied to stone wool slabs. The coating is available in white and in other colours subject to minimum order quantities. The coating may be over painted if desired. Consult ROCKWOOL technical for suitability over paints.

Advantages:

  • Designed to be spray or brush applied onto ROCKWOOL Ablative Coated Batts.
  • Dries to give a sound, flexible white surface finish.
  • During installation of Ablative Coated Batts, the cured coating reduces delamination and increases surface stability for adhesive and fixing sealant application.
