ROCKWOOL 50mm Ablative Coated Batt is a mineral wool insulation product, pre-coated on both sides with a high performance ablative coating. The Ablative Coated Batt is tested to provide up to 4 hours fire resistance whilst also providing an excellent acoustic performance and importantly, maintaining air tightness and reducing unwanted heat losses. Ablative Coated Batts are not intended for use as load-bearing seals.

Key points :
  • Ease of installation - Can be easily cut to the size and shape required to fit the aperture and penetrations.

  • Excellent fire resistance from a single thickness batt - tests have proved the capability of a single 50mm Batt to provide up to 2 hours fire resistance integrity and insulation.  

  • Durable – a reliable and long lasting insulation solution. 

  • Tested for airtightness – also providing the crucial benefits of a proven acoustic seal and preventing the passage of smoke.

  • Environmental – as with all ROCKWOOL products, the Ablative Coated Batt is made from a renewable and plentiful naturally occurring resource. ROCKWOOL insulation saves fuel costs and energy in use and relies on trapped air for its thermal properties.
