Rockwool, manufacturers of non-combustible stone wool insulation, has improved its Ablative Coated Batt product following major investment in its production line at its factory in South Wales.

The product will now come in 1200 x 600mm dimensions as standard.

Rockwool Ablative Coated Batt is the only fire-stopping batt that is manufactured using a fully automated process, which includes the spray application of the ablative coating to Rockwool stone wool slab. This ensures uniform coverage and thickness of the ablative coating which is not always achieved in manually applied processes.


The new sized product comes as Rockwool also makes its Acoustic Intumescent Sealant available in a 600ml foil sausage for the first time. This offers contractors double the capacity of conventional sealant cartridges. A further advantage of the new format is that there is significantly less packaging waste created, as the sausage compresses down to a small disc which can be easily disposed of in mixed waste skips, creating less on-site waste and therefore less landfill.

Rockwool's new Ablative Coated Batt has been tested in conjunction with Rockwool Intumescent Acoustic Sealant and can provide effective fire stopping solutions with up to 4 hours protection.
